IBM PowerLinux Open Source Infrastructure Services Affordable end-to-end infrastructure applications solution for midsize businesses

Businesses demand IT solutions that are relevant, reliable and faster than Highlights ever. Infrastructure and business-specific workloads proliferate as companies grow and address new market needs. The result for data centers is ●● ●●Optimized, open source infrastructure increased server acquisition, expanded storage, new databases, increased workloads solution for faster services floor space and more power consumption. IT costs continue to grow, yet ●● ●●Exceptional reliability and security companies are forced to find ways to reduce expenses. with IBM® POWER7® technology and IBM PowerVM® virtualization Linux has proven that open source applications are as robust as software ●● ●●More throughput per server than developed in traditional ways. As a result, Linux is becoming the open x86 commodity servers standards choice for deploying new workloads that are flexible, secure,

●● ●●Compelling economics to reduce IT costs and cost effective.

Organizations are transforming their IT infrastructures to Linux and open source applications to manage their business. By 2016, it is estimated that open source software will be included in mission-critical software portfolios in 99 percent of Global 2000 enterprises.1

To offset IT software costs, companies are replacing more expensive infrastructure applications with robust open source offerings running on Linux. Open source applications bring savings and flexibility but they can be daunting for companies to deploy and manage. Assembling a solution with components and technology from multiple open source community projects or vendors can result in a complex, hard to manage environment. Small IT organizations in particular do not have the bandwidth to archi- tect or maintain their own solutions. These companies are looking for affordable, ready-to-deploy, end-to-end infrastructure solutions. IBM Systems and Technology IBM Power Systems Solution Brief

To reduce IT hardware costs, companies are leveraging virtualized environments to consolidate workloads on to fewer physi- cal servers. With virtualization, IT organizations are able to lower their x86 server sprawl (less floor space and energy consumption, and fewer servers to manage) but are also faced with new challenges such as virtualization system overhead, and high virtualization software costs. IT staff are looking for a more affordable, efficient virtualization solution.

IBM PowerLinux™ Open Source Infrastructure Services is an ideal platform for fast delivery of essential email, web serving, file/print, and other infrastructure workloads. It provides all the components—key open source infrastructure workloads, Industry standards-based Linux, IBM PowerVM virtualization technology, and IBM POWER7 performance optimized for Linux in an end-to-end solution ready for you to deploy.
