Solid ‐state Storage(SSS)


Solid State Storage (SSS) is a non‐volatile storage replacement for traditional hard disk drives (HDD)

Flash SSS vs. HDD:• Fast, efficient, reliable• More expensive ($/GB)• Better price/performance ($/IOP)

Deployed Capacity


Estimated overall rough average of total storage capacity

comprised of solid‐state: 3%

Estimated Footprint in 24 Months


18

Applications Driving Adoption


19

Use Cases


• Target Use Cases and Applications• Early adoption was focused on

• HPC and custom government apps• Database acceleration• Data mining• Metadata (especially for scale‐out NAS)

• Gradually enhanced by • Auto tiering and caching • More horizontal apps (server virtualization, VDI)

20

Alleviating IO Bottlenecks?


21

Benefits: Actual vs. Expected


22

Challenges


Identifying the Best Solution


• Can you identify apps needing a performance boost?• Does some or all of the capacity need a boost?• Will it fit in SSD?• If so, can you afford it?• Does it need to be shared by multiple servers? • Does it work with existing infrastructure and apps? • Will it be hard to deploy?

Design Considerations


• PCI is faster than drive form factor• In the server is faster than in the array• Caching or tiering gives you more bang for the buck• Caching in real time is better than reactive tiering• Shared storage requirements magnifies the cost of a host‐based SSD solution

• Real‐time capacity reduction magnifies the savings Deduplication Compression
