FlashSystem Core Performance Concepts

•  FlashSystem provide a hardware-only data path −  Custom FPGA-based data movement

decreases latency vs. software •  Lower latency on standard SAN interfaces vs.

competitors •  Comparable latency on SAN compared to DAS

(PCIe) −  All the benefits of shared storage with no

latency impact •  Distributed out-of-data-path CPU processing

Module-level Variable Stripe RAID™ managed by each module across its chips

Chip-level ECC managed by each module using its chips Bit and block errors

2D Flash RAID


Variable Stripe RAID™ (VSR) • Patented Variable Stripe RAID allows RAID stripe sizes to vary. •  If one die fails in a ten-chip stripe, only the failed die is bypassed, and then data

is restriped across the remaining nine chips. No system rebuild needed! • VSR reduces maintenance intervals caused

by Flash failures

Two-dimensional (2D) Flash RAID •  2D Flash RAID: system-level RAID 5

protection layered on top of module-level Variable Stripe RAID.

•  Provides maximum data protection and minimizes recovery times from flash failures, without compromising system performance or availability.

•  Rebuilds only occur if entire flash modules fail – Variable Stripe RAID takes care of small flash failures.

•  System-level RAID is implemented as 10+1 RAID 5 with 4K stripes, plus 1 module reserved as hot spare.

•  System-level RAID is managed through active-active backplane FPGA controllers, not software.

Oracle Acceleration with IBM FlashSystem™

Customer Challenge – Most Oracle applications are highly read-intensive. 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

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

SAP Acceleration with IBM FlashSystem™ Customer Challenge – The vast majority of the Worlds SAP Databases consume less than 2TB of Storage. 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
