EXECUTIVE SUMMARY

This paper examines the economics and performance of a new data center infrastructure solution from Ericsson called Ericsson Hyperscale Datacenter System 8000 that is poised to reshape how enterprise data centers are architected to meet the challenges of the hyper-connected Networked Society. Based on the paradigm-shifting ® Rack Scale Architecture, Ericsson Hyperscale Datacenter System 8000 delivers a hyperscale cloud solution for enterprise data centers that will enable quantum leaps in efficiency, infrastructure elasticity, and economics.

Our research found that companies implementing Ericsson’s hyperscale platform can capture significant TCO savings compared to traditional data center infrastructures — generating CAPEX savings of up to 55%, OPEX savings of up to 75%, and a return on investment (ROI) of up to 138% for large enterprise data center operators over a five-year period.

Ericsson Hyperscale Datacenter System 8000 generates these savings by delivering performance and scalability on par with data center leaders such as , and in a commercially available platform. By creating a pool of infrastructure components leveraging Intel’s new RSA technology, SDI techniques, and optical networking, data center operators can better match infra- structure capacity with application and network workload requirements, thereby improving utilization of these resources. In this white paper we detail the range of value drivers that support these results and estimate the impacts across different data center scale scenarios.

In an economy where companies face exponentially rising data traffic and demands for new cloud computing capabilities, data center operators need to take a close look at new ways to provide IT services that are more flexible, cost-effective and vastly more scalable than what they offer today. Operators need to ask themselves whether they are ready for the Networked Society.

WELCOME TO THE NETWORKED SOCIETY

We live in a world where five billion people are connected and where mobile, broadband, and cloud are transforming the fabric of society. Ericsson calls it the Networked Society and it is impacting our everyday lives in profound ways, not unlike the titanic shifts of the industrial revolution more than a century ago. Today, Internet connectivity and mobile communications are taken for granted.1 And with the rise of the Internet of Things, more products are becoming “smart” and connected with other things across an expanding global cloud network. Meanwhile information streams from these networks are proliferating, spawning opportunities to harness Big Data for competitive advantage as well as social progress.

CHALLENGES FACING The world’s data traffic is exploding as a result. Analysts estimate that global workload growth will DATA CENTERS increase by 81% between 2015 and 2018, with the highest growth (113%) being cloud-based work- TODAY loads. And Ericsson is currently forecasting compounded annual growth of mobile traffic of 45% • Scaling to support between 2015–2021.2 All of this is placing enormous pressure on businesses and data centers to keep exponential growth of pace. Indeed, one of the most critical challenges facing enterprise data centers in the next few years application and network will be how to scale their computational capacity to meet exponentially growing digital workloads workloads with minimal in an economically efficient way. additional costs to the business (OPEX/CAPEX) To thrive in the Networked Society, businesses will need to seize fast-emerging digital business • Transforming service opportunities that require immediate deployments of compute, storage and networking resources. capabilities from back Demand can also recede or shift to new projects just as quickly, so enterprise data centers need to be office operations to a able to turn capacity on and off at short notice. This means data centers will need to provide business strategic revenue driving, stakeholders with the same “infrastructure on tap” capabilities that modern cloud-service providers customer-facing asset like have pioneered.

• Increasing flexibility and Indeed, as McKinsey & Company has observed, one of the top priorities for enterprise data centers speed of delivery of will be establishing a commercial-style business relationship with internal customers. This will require infrastructure services to an ability to standardize the data center’s service offerings, provide a solid “bottom-up” service cost meet the dynamics of digital industrialization structure, implement robust infrastructure management solutions, and reinvent the way they serve customers.3

TRANSFORMING THE ENTERPRISE DATA CENTER

The great majority of enterprise data centers today are ill-equipped to help businesses succeed in the Networked Society. Designed primarily to deliver back-office applications to internal business users, the traditional data center is burdened with an inefficient and costly architectural design that prevents it from scaling and flexing rapidly to meet the changing workloads of a modern digital enterprise.

One of the biggest design inefficiencies of the conventional data center is the creation of separate silos of hardware and software for each application workload. Because resources are not shared between workloads, investments in capacity buffers (over-provisioning) and high availability need to be made separately for each workload, adding to the overall data center cost burden.

Increases Proportionally Reduces hardware capital increases operating resource expenses expenses utilization

Moreover, because traditional data centers typically follow a lengthy “procure-to-provision” process tied to the business’s annual capital investment cycle, system architects will typically over-provision the infrastructure to weather these lengthy procurement cycles. Enterprise architects we interviewed said they typically design 30% over-capacity for a standard workload and up to 60–70% for mission- critical workloads.

Adding to data center complexity and cost is the wide variety of proprietary infrastructure components associated with each application stack. The bill of materials includes database appliances, storage solutions, servers, and networking solutions — all procured on a per-application, per-department basis. Heterogeneous environments like this always require more people to administer, adding to OPEX.

Virtualization and Software-Defined Infrastructure

To address these inefficiencies, the traditional data center is evolving. Server virtualization technology has allowed system administrators to have more flexibility in provisioning infrastructure resources. According to Forrester Research, 77% of x86 servers in enterprise data centers have been virtualized.4 Analysts estimate that virtualization has lifted x86 server utilization from 5–10% to over 30%.5 SOFTWARE-DEFINED INFRASTRUCTURE The success of server virtualization has opened the door to virtualizing other data center components, (SDI) such as network and storage, and leading to the next wave of enterprise data center optimization — Software-defined infrastructure software-defined infrastructure (SDI) — which seeks to virtualize the entire data center infrastructure. is the definition of technical Accelerating the spread of this new architecture is an industry-standard technology blueprint developed computing infrastructure by Intel called Intel® Rack Scale Architecture (RSA). entirely under the control of software.

Hyperscale Pioneers

In fact, our research found that these custom-built hyperscale data centers, when accommodate increasing compared to traditional data centers, deliver four times the level of CPU utilization, increase network volumes of data and work- utilization by as much as 26%, and dramatically lift productivity by enabling a single IT administrator loads.

Recognizing the game-changing potential of Intel Rack Scale Architecture and software-defined infrastructure, technology leader Ericsson developed a data center solution — Ericsson Hyperscale Datacenter System 8000 — that brings the benefits of hyperscale computing to enterprises in a commercially available solution. For the first time, enterprises can deliver cloud computing performance and manageability on par with hyperscale leaders Google, Facebook and Amazon.

As discussed above, traditional data centers typically build dedicated infrastructures for each workload. Server virtualization has helped break down some of these silos, but in practice this technique can only be applied to a portion of enterprise workloads. Many enterprise applications, for example, are too costly to virtualize, while other legacy applications can present performance and tuning challenges

in virtualized environments. In addition, the performance of certain business-critical workloads — particularly high-speed, revenue-generating, and customer-facing applications — can suffer from the overhead latency effects of virtualization, and are excluded for that reason.

Ericsson Hyperscale Datacenter System 8000 overcomes these limitations by creating a pooled set of physical layer infrastructure components to support the virtualized and application layers, enabling businesses to flexibly support the dynamic demands of heterogeneous workloads.Administrators use management software — the HDS Command Center portal (or via APIs to an existing enterprise management system) — to define the optimal infrastructure components for each workload. Figure 3 compares a traditional data center architecture with the Ericsson platform, showing the advantages of deploying a centralized and homogenous bare metal layer of resources managed by a centralized software controls system (HDS Command Center) across all workloads.

The ability to rapidly match workloads with hardware components in a common pool of bare-metal infrastructure enables data centers to increase the average utilization of components. Our research indicates that system administrators could routinely maintain server utilization rates of approximately 60% across most workloads.7 Disk Disk

Copyright © 2016 Mainstay, LLC 7 An Economic Study of the Hyperscale Data Center White Paper

We found three critical drivers of utilization improvements. By replacing the “procure-to-provision” planning process with a streamlined, software-defined “pool-to-provision” planning process (see next section), system administrators can better match infrastructure to workload demands, removing the overprovisioning allowance that is prevalent in current workload planning decisions. In our discussions with data center experts, we found this driver could improve utilization by up to 60%. Another utiliza- tion booster is the ability to dynamically allocate CPU resources across servers and racks, allowing administrators to quickly migrate resources to address shifting demand. We found this can drive 100–300% greater utilization for virtualized workloads and 200–600% for bare-metal workloads.

Finally, HDS Command Center’s open platform approach allows data center operators to manage their entire data center infrastructure (other vendor solutions as well as Ericsson) through a single portal. This enables system administrators to identify opportunities to allocate infrastructure to multiple workloads, improving utilization by up to 50%. For example, infrastructure used to support Workload A, which experiences peak demand during the day, could be shifted to Workload B, which experiences peak demand during the night. The visibility and reporting capabilities of HDS Command Center also allow operators to audit all infrastructure components, enabling them to locate under-utilized “ghost servers” (those not procured or managed by IT) and bring these resources under IT management. By leveraging the management and reporting capabilities of HDS Command Center, data center operators could improve utilization by up to 10%, our research shows. Figure 4 summarizes the range of utilization improvements that could be achieved by implementing the Ericsson Hyperscale Datacenter System 8000 platform.

By contrast, server utilization rates for traditional data center workloads typically range between 6% and 15%, with hardware virtualization benchmarks averaging closer to 30%.8 Whether applications are virtualized or running on bare metal, the ability to pool infrastructure at the component level using the Ericsson Hyperscale Datacenter System 8000 platform creates a homogeneous data center infrastructure across all workloads.

Optimized Data Center Infrastructure Management: From “Procure-to-Provision” to “Pool-to-Provision”

Ericsson’s software-defined data center platform will modernize the way operators manage infrastructure planning and procurement. The focus of planning cycles, for example, will move from procuring infrastructure for individual workloads (“procure-to-provision”) to managing the disposition and deployment of the data center’s entire of pool of hardware (“pool-to-provision”).

This shift to more holistic planning will eliminate traditional over-provisioning practices and enable rapid reallocations based on actual usage patterns. To effectively manage the new planning approach, operators may find they need to modify their organizational structures somewhat, relying less heavily on individual component solution specialists (server, storage, and networking experts) and more heavily on cross-component designers and SDI experts.

INSIDE THE ERICSSON HYPERSCALE DATACENTER SYSTEM 8000 PLATFORM Ericsson’s new platform introduces unique capabilities to enable companies to build a software-defined hyperscale data center.

• Resource pooling. Leveraging RSA, Ericsson’s platform reinvents the way system administrators provision, manage and monitor data center infrastructure assets through the pooling of infrastructure components. Resource pooling results in significant improvements in asset utilization.

• HDS Command Center. This system management portal gives IT administrators full visibility into all data center infrastructure elements (including non-Ericsson system elements via APIs) and enables composing a system using pooled resources that include compute, network and storage based on workload requirements. Command Center also provides auto-provisioning, real-time performance tracking, and triggers to adapt to workload shifts.

• HDS Optical Backplane. Ericsson’s state-of-the-art optical interconnect removes the traditional distance and capacity limitations of electrical connections, enabling maximum pooling of resources and flexibility in physical placement of data center assets, while increasing the lifespan of racking chassis and cabling by 3-4x.

BUSINESS IMPACT AND TCO ANALYSIS

What specific benefits and savings can businesses expect to achieve if they implement the Ericsson Hyperscale Datacenter System 8000 platform? Our analysis, based on extensive discussions with data center engineers and industry experts, estimated a range of impacts spanning three key business-value categories, as summarized in Figure 59: Figure 5. Ericsson Hyperscale Datacenter System 8000 Economic Value Tree: Impact Categories

• System administration savings via Command Center workload lifecycle management Operating Expense • Power savings from improved asset utilization, density, PDU architecture (OPEX) Savings • Optical backplane wiring and lifecycle cost savings • Server/CPU consolidation and improved utilization reduces component costs • SDN Architecture + Ericsson hyperscale networking solution reduces cost per port Capital Expense • SDS Architecture + Ericsson hyperscale storage solution reduces total capacity required (CAPEX) Savings • Facility infrastructure density improvement • SDI agility to migrate infrastructure reduces total capacity requirements • Enable revenue generating services Revenue and • Deliver Networked Society strategic opportunities Other Strategic • Create “infrastructure on tap” or “AWS-like” asset nimbleness Impacts • Improve “green” data center measures

Estimates of TCO and business impact will vary depending on the existing maturity and operating practices of the enterprise data center being studied. To simplify our analysis, we used third-party benchmarks to estimate the current operating practices of data centers today. For example, virtualization of enterprise data centers has helped to drive additional cost savings and higher efficiencies but our research has found that the range of virtualization can vary from 25% to 75% of data center workloads.

Operating Expense (OPEX) Savings

Our analysis showed that the Ericsson Hyperscale Datacenter System 8000 solution offers clear opportunities for reducing operating costs. These drivers of OPEX savings can be grouped into five categories, as shown in Figure 6 and summarized below.

• Power and cooling savings. Our research shows that Ericsson’s high-utilization platform will enable data centers to operate with substantially less physical infrastructure, as detailed in the section on CAPEX savings. Based on these estimates, the average data center could reduce overall power and Source: Mainstay Partners cooling costs up to 72%.11

• Reduced software licensing and support costs. As organizations boost component utilization and cut back on data center hardware — particularly CPUs — the cost of software licensing would fall proportionally. Based on our earlier estimates, companies could realize as much as a 30% reduction in ongoing virtualization software license costs.12 However, these savings are offset by software license investments in HDS Command Center Software. Our analysis found that this TCO category would be a net investment for operators.

• Lower real estate costs. In most cases, real estate cost savings will take the form of cost avoidance as companies find they can accommodate growth more efficiently and thus use existing data center space longer.

• Server CAPEX savings. As enterprises shift workloads to Ericsson’s software-defined infrastructure, they can expect to reduce capital expenditures on servers (CPUs) in line with our earlier 2-4x utiliza- tion improvement estimate. In estimating the total savings potential for an enterprise data center with Strategic 75% virtualizedImpacts workloads, we calculated a 65% TCO savings for server-related CAPEX spending. Companies can also economize on CPU costs by optimizing how they are deployed in the hardware pool. For example, as a CPU ages and newer components are brought online, administrators can match older components to less critical workloads, extending the average life of a CPU from three to five years, according to data center experts we interviewed. Many companies will see additional savings in lower software license costs tied to CPU cores or sockets.

• Storage savings. By employing an advanced erasure coding storage Figure 10. Traditional vs. algorithm, Ericsson Hyperscale Datacenter System 8000 storage Ericsson hyperscale platform’s minimizes the replication of unstructured data across the data center, unstructured data storage enabling cost reductions in disk storage by as much as 35% (Figure Amount of Storage Required for Similar Workloads in Petabytes 10). In addition to lowering physical disk CAPEX, the enterprise 3.6 should also see reductions in storage-related software license costs.

• Network CAPEX savings. Ericsson’s software-defined networking topology, combined with the physical advantages driven by its optical 1.7 backplane racking solution, will increase the overall efficiency and effectiveness of the data center’s physical switch infrastructure, enabling capital cost reductions in this area. In addition, our analysis Traditional Ericsson Hyperscale

shows that network-layer savings will increase exponentially as the scale and complexity of the data center increases.13

• Power and cooling equipment savings. A side benefit of migrating to Ericsson’s streamlined infrastructure is a corresponding reduction in the amount of power backup systems and cooling equip- ment required. Since these savings are likely to represent only a small portion of overall cost savings, they are documented here for completeness but not included the TCO calculations that follow.

Revenue and Other Strategic Impacts

Although the specific purpose of this study was to detail the potentialTCO savings of the Ericsson hyperscale platform, our research and discussions with data center and industry experts also uncovered a range of strategic and revenue-generating opportunities that enterprises could capture when they are equipped with hyperscale data center capabilities. Although the sheer diversity and unpredictability of these opportunities makes it impossible to quantify for the average company, they may well represent the greatest potential source of value for many enterprises, especially those seeking business transfor- mation through digital initiatives.

For example, a hyperscale platform like Ericsson’s is ideally suited for enabling IoT and Big Data initiatives, both of which require massively scalable compute, networking and storage capabilities. McKinsey estimates that the IoT could have a total economic impact of $11.1 trillion per year by 2025,14 the equivalent of 11 percent of the world economy. However, to exploit IoT opportunities, data centers will need to bring new capabilities into play, such as enabling interoperability and the ability to analyze huge volumes of data. Ericsson Hyperscale Datacenter System 8000 makes all of this possible and at a lower cost basis than the competition. For “hyperscale-enabled” companies, billion-dollar opportunities become addressable markets.

Other capabilities enabled by the Ericsson hyperscale platform, such as rapid workload provisioning, optimal hardware utilization, and better infrastructure visibility and manageability, will enable enter- prise data centers to provide services comparable to what’s available from public cloud providers such as AWS. Furthermore, by increasing data center density, conserving space, and improving power usage effectiveness, or PUE, the Ericsson hyperscale platform will help companies meet environmental sustainability goals, an important strategic priority for many companies.

5-YEAR TCO IMPACT FOR ENTERPRISE DATA CENTERS

What is the total economic benefit enterprises could gain from implementing Ericsson Hyperscale Datacenter System 8000 in a typical data center? To estimate the impact, we created a total cost of ownership (TCO) model, factoring in the range of value drivers described in the previous section. The model analyzes operating scenarios for three sizes of data centers: small (1 rack), medium (6 racks), and enterprise-scale (60 racks), recognizing that infrastructure components can vary greatly in each case depending on industry, geographic coverage, the types of applications being run, and other factors.

TCO and ROI Summary

The results of our TCO analysis are clear: Enterprise data centers that adopt the Ericsson Hyperscale Datacenter System 8000 platform can expect to capture significant savings — as much as 55% in CAPEX savings and 75% in OPEX savings for a 60-rack data center (see below for more details on our TCO modeling), with an estimated overall TCO savings of 63%. This translates into an estimated ROI of 138% over five years.

One of the key drivers of TCO savings is greater CPU utilization, which allows for the deployment of fewer servers and CPUs, less network hardware, and less storage disk. The Ericsson platform’s ability to transform the “procure to provision” process into a vastly more efficient “pool to provision” process enables more frequent, collaborative planning efforts that help avoid over-investment in infrastructure. For these utilization and labor efficiencies to be fully realized, however, organizational changes may be required to facilitate collaborative planning across departments and optimize compute, storage and network capacity.

Ericsson’s Optical Backplane solution drives more efficient cabling, resulting in fewer cables procured and ease of physical deployment resulting in lower OPEX spending. The automation and orchestration with HDS Command Center, results in being able to scale up the amount of infrastructure managed per systems administrator. Less infrastructure additionally reduced power and cooling, software licenses and hardware and software support costs.

Figure 11 summarizes the estimated magnitude of cost savings and ROI that could be achieved at different scales of deployment. Figure 12 shows a more detailed breakdown of savings by data center cost category.

TCO Model Approach and Assumptions

To establish realistic assumptions and benchmarks used in the model, we worked closely with data center and industry experts, including operators at Fortune 500 companies, and took a conservative view of the potential cost savings of the Ericsson hyperscale platform. For example, wherever possible, we have assumed a conservative basis for calculations, such as using discounted “market” prices for hardware and other components.

For the same reason, we chose not to include the potential revenue or strategic benefits that might result from providing the enterprise with greater agility, speed or environmental sustainability, as outlined in the previous section. Although these benefits could be substantial, even exceeding the other categories of benefits, we judged them to be too variable and unpredictable to include in theTCO model.

The relative percentage of virtualized vs. non-virtualized (or bare metal) workloads can vary on a case by case basis. We chose to present a conservative view of the impact by assuming that 75% of the workloads had already been virtualized, thus using a relatively efficient baseline for our analysis. Based on our research, we set the average CPU utilization in non-virtualized environments at 15%, and virtualized environments at 30%. Because of the Ericsson platform’s superior resource pooling and disaggregation capabilities, its utilization rate was set at 60%, which is consistent with performance levels achieved at leading hyperscale data centers.

The TCO analysis covers a 5-year period and factors in the depreciated costs of the infrastructure. The following CAPEX elements were considered: server hardware, storage HW, network hardware, cable hardware, physical deployment effort, virtualization software, management software. The following OPEX elements were considered: hardware support, software support, HDS Command Center software support, system administration, power and cooling, and space utilization.

Our analysis assumed a greenfield approach to implementing the Ericsson platform. In our model, the compute-storage-network environment is completely converted to the Ericsson hyperscale platform on Day One and compared to a traditional, non-hyperscale operating model. Since the infrastructure is assumed to be fully-depreciated, there is no time-lag or phasing of impacts. A phased approach model would need to be created for cases that are not greenfield implementations. Our recommendation is to use the framework, benchmarks and research provided in this paper as a “starter kit” to develop a custom ROI analysis that takes into account the unique features and opportunities of your individual data center.

THE JOURNEY TO HYPERSCALE

For most enterprise IT organizations, moving to an Ericsson hyperscale platform won’t happen overnight. In reality, it will be more of a journey than a flip of the switch. Enterprise data center management will be tasked with not only transforming the physical architecture of the data center, but also changing work processes and job descriptions in order to maximize TCO savings — a process that will likely take months, if not years.

EARLY RESULTS: GOING HYPERSCALE AT ERICSSON’S STATE-OF-THE-ART DATA CENTER Ericsson is committed to being its first and best customer with its hyperscale data center platform. As part of its 2016 IT planning efforts, Ericsson has prioritized its engineering systems infrastructure as the best place to start. In our interviews, IT executives explained that the Ericsson Hyperscale Datacenter System 8000 solution was particularly well suited for the engineering systems environment given the very high CPU demand of its application workloads.

Executives said that the platform’s HDS Command Center will help the IT team more effectively manage the infrastructure and meet the unique requirements of its engineering applications. With Ericsson’s hyperscale platform, the IT team is expected to achieve an estimated 400% improvement in system utilization across more than 30,000 servers.

The team expects to launch the hyperscale project in 2016 and then expand the platform’s capacity over several years. Results from the project will be analyzed and shared widely within the company to help improve the product for internal users as well as Ericsson’s customers.

In most cases, enterprises will be best served by following an incremental approach to hyperscale transformation. That could mean starting with a pilot on a selected workload in order to demonstrate the benefits of pooling resources and delivering “infrastructure on tap.”Another initial step, which Ericsson itself took internally, is to leverage the audit capabilities of the HDS Command Center to gain full visibility into the utilization of the existing infrastructure and find dormant or shadow infrastructure that may be unknown or poorly leveraged. This activity can provide an early return by eliminating dormant or underproductive assets.

After successfully proving the platform’s capabilities in the pilot, most organizations will be ready to plan for a wider rollout. Ericsson, for example, decided to leverage the visibility gained from its HDS Command Center audit to identify areas of the data center that could benefit most from the hyperscale platform and then start the deployment there (See callout: “Early Results: Going Hyperscale at Ericsson’s State-of-the-Art Data Center”).

Capital depreciation schedules will likely influence the pace of change, since most companies will want to avoid write-offs of existing equipment and prefer to phase in the hyperscale platform only when legacy hardware has been fully depreciated. This financial constraint would suggest a three- to five-year journey for most enterprises.

Considering the comprehensiveness of Ericsson’s hyperscale platform and its potential for transforming the business, companies should take advantage of Ericsson’s experts in their planning efforts. This could include the development of a multi-year business case, a phased implementation approach, and a technical design evaluation that explores the range of opportunities for leveraging this next-generation data center architecture.

To be conservative, the analysis assumed 75% of the workloads are virtualized, leading to a 69% improvement in server utilization across the data center. 9 Given that the solution has not been released commercially at the time of this paper, all quantifications of impact are estimates based on available research and assumptions made in concert with the experts interviewed. 10 These savings are dependent on enterprise data center operators transforming the people, process and technology practices as described in this piece. 11 Assumes $0.10 per KWH @ 8,736 hours per year; wattage per component (storage, network, server) estimated based on available benchmarks; assumes rack occupies 30 sq. ft. of data center space at $310/sq. ft. 12 Data center infrastructure TCO includes software license costs and annual support costs for operating system software, virtualization software, disaster recovery software, and the like. 13 This is due to two major factors: (1) As the complexity and requirements for the network increase the costs of the switching environment grow exponentially; (2) The fabric-based network environment, coupled with the fiber-based racking environment, allow for more flexibility in how you physically deploy the network switches into the racking environment. Due to electrical connection limitations, typical top-of-rack switches are required to manage very dense environments. With the Ericsson hyperscale platform, these physical switches can be better utilized because of the distance and low-latency capabilities of optical connections. 14 Mckinsey Global Institute’s June 2015 survey. 15 Cost savings are estimates are based on full adoption the Ericsson Hyperscale Datacenter System 8000 solution as well as implementing new organizational best practices discussed earlier, such as holistic infrastructure planning that reduces hardware overprovisioning. 16 CAPEX includes: server, storage, network, cabling, power and cooling equipment hardware costs, and virtualization and orchestration software license costs. 17 OPEX includes: server, storage, network hardware support costs, virtualization and orchestration software support costs, system administration labor costs, power, cooling and space costs.
