3. Cosmos Business Systems & IBM Hellas The New Flash Era – IBM Storage Flash Technology& StorwizeFamily ? What is the role of the storage is:

4. Cosmos Business Systems & IBM Hellas The New Flash Era – IBM Storage Flash Technology& StorwizeFamily The role of the storage is: Read Data to give/take data at the request of the application In consequence, the only impact storage has to the application performance is the amount of time the processors must wait Write

5. Cosmos Business Systems & IBM Hellas The New Flash Era – IBM Storage Flash Technology& StorwizeFamily CPU performance up 10x this last decade Storage has grown capacity but unable to keep up in performance Systems are now Latency & IO bound resulting in significant performance gap Performance Gap From 1980 to 2010, CPU performance has grown 60% per year* …and yet, disk performance has grown ~5% per year during that same period**

14. Cosmos Business Systems & IBM Hellas The New Flash Era – IBM Storage Flash Technology& StorwizeFamily Variable Stripe RAID™ • 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 Unique Business Benefit: Fewer Flash Module Replacements 10 Chips RAID Group … 16 Planes FAIL …

15. Cosmos Business Systems & IBM Hellas The New Flash Era – IBM Storage Flash Technology& StorwizeFamily 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. ExternalInterfaces (FC, IB) RAID Controllers RAID 5 withinFlash Modules(9 data + 1 parity) IBM 2D Flash RAID Unique Business Benefit: Maximize Data Protection RAID 5 across Flash Modules (10 data + 1 parity + 1 hot spare)
