Virtualized SAP HANA on VCE Vblock in Production White Paper VIRTUALIZED SAP HANA® ON VCE VBLOCK IN PRODUCTION — A REALITY Benefits of Running Virtualized SAP HANA on VCE Vblock™ with Deloitte Cloud ServiceFabric™ on Hybrid Cloud EMC Global Solutions Group Abstract An international team of Deloitte, EMC, VMware, Cisco, and VCE functional and technical experts worked to identify the challenges of running virtualized SAP HANA on a Vblock in Production and over a hybrid cloud. Through this Proof of Concept, named Project RUBICON, that multi-company team created real- world use cases for testing Production workloads, analyzing the results, suggesting solutions for mitigating risks, and offering solutions for possible implementation of SAP’s new S/4HANA in virtualized mode.

Yet, HANA deployments in Production, whether virtual or bare metal, are not as common as traditional SAP NetWeaver so it is natural that certain customers have concerns with the maturity, system behavior, and reliability under Production-level workload, and customers are even less certain of how HANA would work in a hybrid cloud. This white paper provides proof points and a reference architecture for customers desiring to take advantage of the efficiencies, performance and scalability of virtualized SAP HANA environments running on Vblock under Tailored Datacenter Integration (TDI) mode and in a hybrid cloud model instead of on bare metal physical appliances. This paper addresses those customer challenges and concerns by: Proving that virtual SAP HANA “appliances” on a VCE Vblock can easily handle Production workloads while offering long distance disaster recovery not possible with bare metal Demonstrating that monitoring and reporting tools can provide the required insight to ensure stability and scalability of virtualized SAP HANA on a Vblock under TDI Validating how to operate SAP HANA in a hybrid cloud model over long distance Deloitte, EMC, VMware, Cisco, and VCE in conjunction with Blue Medora and Worksoft worked together to show how to monitor, measure, and take actions upon the entire computing stack of a virtualized SAP HANA Production system to achieve stability and scalability under heavy workload. This team also showed how SAP HANA can realistically be implemented in hybrid cloud mode between the Deloitte datacenter in Georgia and the EMC datacenter in North Carolina, located 550 kilometers apart. This Proof of Concept used a workload equivalent in volume and scope to a month-end closing event, by loading inventories, creating planned orders, calculating lead times, etc., with over 2,000 concurrent SAP users logged in and multiple MRP batch jobs. Over the 2 hour test run, this massive load generated the equivalent of 784,000 dialog steps, 680,000 Updates, and 144GB of SAP HANA logs per day. Under this large workload, the virtualized SAP HANA “appliance” running on Vblock proved to be stable and scalable according to the monitoring tools from Blue Medora Pack for SAP HANA, Cisco Intelligent Automation for SAP HANA, and EMC ViPR SRM, confirming that there is no difference in stability and performance between a traditional, bare metal infrastructure and a virtualized, converged environment based on the Vblock. The monitoring tools were even able to predict possible future failure, while providing reporting on compliance with agreed-to Service Level Agreements (SLAs). Since long distance disaster recovery for SAP HANA is very important in Production, EMC RecoverPoint proved that it could replicate large amounts of SAP HANA logs over long distance to restart HANA at the remote site, with a more than acceptable Recovery Point Objective (RPO) at peak workload. The POC also demonstrated that Deloitte’s Cloud ServiceFabric™ (CSF) can be extended to a hybrid cloud model by implementing and controlling CSF endpoints in Durham, NC from the CSF provisioning and monitoring portal in Suwanee, GA. By relocating workloads from one datacenter to another without data loss, Cloud ServiceFabric works well in hybrid clouds for maximum optimization of resources. The results detailed in this white paper suggest that perhaps the reference architecture proposed in this POC could be the ideal platform to

    Powerlink May 2013 Frequently Asked Questions: EMC ViPR Software- Defined Storage Software-Defined Storage Table of Contents What's New? Platform Questions Customer Benefits Fit with Other EMC Products What's New? Question: What is being announced? Answer: On May 6, at EMC World, EMC announced EMC ViPR Software-Defined Storage. EMC ViPR Software-Defined Storage is a revolutionary approach to storage automation and management that transforms existing heterogeneous physical storage into a simple, extensible and open virtual storage platform. Question: How does ViPR work? Answer: EMC ViPR is a lightweight software platform that abstracts storage with all its unique capabilities from physical arrays into a single pool of virtual storage. Storage administrators then create virtual storage arrays that they can manage at the virtual layer according to automated policies. Storage administrators define various Virtual Storage Pools that represent storage performance characteristics and capabilities suited for particular workloads. Data services, such as block, file and object data services run on top of the platform and leverage the unique attributes of the Virtual Storage Pools and arrays. ViPR centralizes storage management to monitor utilization and performance all though a single interface across physical and virtual storage. ViPR is also extensible, so any customer, service provider or vendor can easily augment it to support additional non-EMC storage, develop new data services and integrate with cloud stacks such as VMware, Microsoft and OpenStack. ViPR supports open APIs including, Amazon S3, EMC Atmos and OpenStack Swift so applications written to those APIs can run on ViPR. Question: How is EMC ViPR different from storage virtualization? Answer: ViPR is unlike previous attempts at storage virtualization in that it decouples the control path from the data path.

    PRODUCT OVERVIEW DELL EMC VXRACK SYSTEM 1000 SERIES Hyper-Converged Infrastructure at scale Converged infrastructure brings together the disparate infrastructure elements that power IT, including servers, data storage devices, networking functions, virtualization, management software, orchestration, and applications. The purpose: To simplify IT by breaking down the silos in the data center, reversing the status quo of static and inflexible pools of resources. Converged infrastructure solutions are proven to significantly speed deployments, make infrastructure more agile, and simplify IT operations—all of which is critical to successfully deliver IT as a service. In contrast to traditional converged infrastructure solutions, hyper-converged infrastructure (HCI) is a software-defined architecture with integrated compute, networking, software-defined storage, and virtualization. It enables compute, storage, and networking functions to be decoupled from the underlying infrastructure and run on a common set of physical resources that are based on VxRack System industry-standard x86 components. Using hyper-converged infrastructure, customers can start with 1000 Series a small deployment, and then flexibly scale out to support dynamic workloads and evolving Modular hyper-converged infrastructure business needs. system that delivers extreme scalability The VxRack System 1000 series is a hyper-converged platform that complements Dell EMC and flexibility converged infrastructure systems.
