Why Applications don’t perform?Waiting for data…
• Apps on Multi-core, Multi-Socket Servers limited by slow storage• Datasets double every 9 – 12 months

Enterprises desperate for Performance Storage
Moore’sLaw
Not so Much

Alternative Solutions
• Add more DRAM• Not enough Slots• Multicore's eat it up• Power Hungry Memory• Cache too small
• Build large Disk Arrays (SAN)• Space and Power Hog• Doesn’t help latency
• Custom application tuning• It’s on the List

• Steady, Predictable Performance under various workloads― 4x better performance than alternatives― 300,000 random IOPS sustained , mixed read-write, 4K Block Size
› Equivalent of 1000 FC HDDs― Performance achieved at full capacity
• Enterprise-class Data Reliability― Advanced multi-level error correction― Global wear-leveling ― Flash-aware Hardware RAID
• Modular Design for Field Serviceability― Flash modules - Stackable, Removable― RAID life cycle for module recovery

PCIe Gen 3 Future
PCIe Cluster with Shared I/O • PCIe Gen 3• Hot swapping• Peer-to-peer communication• Much lower overhead thanks to a new 128/130-bit encoding scheme• 1.5 percent overhead compared to 20 percent in Gen 2
• Growth in Multi-core CPU chips with rumored PCIe Native Support • Intel – “Ivy Bridge - EX” 10-20 Core Processors in 2012• AMD – “Terramar” 10-20 Core Processors in 2012
• Major OEMs designing servers with front-loading PCIe slots• Industry standardization around a PCIe SSD Drive form factor
