IBM FlashSystem is IBM's portfolio of all-flash storage arrays that provide ultra-low latency, high performance storage for transactional databases, virtualization, and other I/O intensive workloads. The arrays use custom FPGA technology and a layered data protection approach including chip-level ECC, variable stripe RAID, and 2D flash RAID to optimize performance while maintaining reliability. Models are available with SLC or eMLC flash and range in capacity from 1TB to over 1PB within a single rack. IBM FlashSystem can accelerate performance of Oracle, SAP, virtual servers and other applications by up to 12x over conventional storage.

As such, additional processing power alone does little or nothing to improve performance. By placing all read data on low latency flash storage, reads will be performed much faster, boosting Oracle performance by up to 12x over conventional disk systems with no tuning or changes to code or system architecture. IBM FlashSystem shared flash storage systems will • Decrease I/O wait time in mission critical Oracle workloads • Deliver the lowest latency available on any SAN platform • Accelerate commonly I/O-bound workloads, including transactional, batch and complex analytics Delivers Extreme Performance, Macro Efficiency, and Enterprise Reliability for

- 21. © 2013 IBM Corporation21 Virtual Servers and VDI with IBM FlashSystem™ Customer Challenge - Virtualized servers and Virtual Desktop Infrastructure (VDI) push conventional storage systems to their performance limits. The result? Poor application response times and a bad customer experience. Introducing an IBM FlashSystem into virtualized environments will result in up to 16x faster response times for the most common virtualized applications. Couple this performance to the ‘log on’ or ‘boot’ storm and make system use productive again. IBM FlashSystem shared flash storage systems will • Eliminate I/O density and hot spot issues that are common to highly virtualized environments • Control and mitigate ‘log on’ or ‘boot’ storm performance issue • Deliver storage consolidation without sacrificing performance, thus driving a higher V:P ratios thus increasing server utilization Delivers Extreme Performance, Macro Efficiency, and Enterprise Reliability for

SAP is pushing clients to accelerate performance by adopting the HANA in-memory database architecture. This often leads to a significant re- architecture of the entire SAP infrastructure, which drives high cost and a risk of disruption in service delivery. IBM FlashSystem shared flash storage systems will • Eliminate I/O bottlenecks in mission critical SAP workloads • Provide the lowest latency of any SAN-based storage solution for time-sensitive workloads with IBM MicroLatency™ • Enable a small, cost-effective pool of flash storage to deliver extreme performance improvements • Support a phased approach to HANA adoption by delivering consistently higher performance for SAP BW workloads with no re-architecture required Delivers Extreme Performance, Macro Efficiency, and Enterprise Reliability for &
