Why Solid State Disks?Drives are getting Bigger not Faster

• 1956 RAMAC– The first hard disk drive– 5 MB storage– 1,200 RPM

• 2008 – 1 TB storage– 15,000 RPM

• From 1956 to 2007:– 12.5 times increase in RPM– 200,000 times increase in capacity

How do disks Arrays try to solve performance issues?

• Massive Arrays of Disks:

• This only ensures that access time doesn’t degrade below the 5 - 10 ms Access time, and that parallel operations can be handled.

• Can Solve: IO per second problems, Bandwidth problems

• Does not solve latency problems

Solid State Disks: A New option

• Dramatically lower response time• Extremely high IOPS and Bandwidth• No difference in performance for random or sequential

performance.

RamSan-500 Specifications

Performance• 100,000 IOPS (sustained random read)• 25,000 IOPS (sustained random write)• 500,000 IOPS to Cache (sequential reads or

writes)• 2 GB/s sustained read or write bandwidthLatency• <200 us for random reads• <15 us cache hit (read or write)

RamSan-500The 1ST Enterprise Flash SSD

• Announced August 2007• Deployed December 2007• To date the largest customer deployment is

10TB• A European Telecom is currently using 5TB

in production for Oracle acceleration• Currently deployed on 3 continents

Why Didn’t TMS Make a form factor SSD?

• Drives take their shape based on the spinning platter

• Flash has no similar physical requirement

Typical RamSan-500 Deployments

• Used as a storage tier between memory and disk

• Allows much higher capacities than server memory at a much lower price.

• Databases that have >256GB of performance sensitive files.

• Bandwidth intensive applications (1 rack can hold over 20 TB of storage with 20 GB/s of bandwidth)

RamSan Solid State Disks:Customer Examples

Nexa Technologies, Inc.

• Nexa Technologies, Inc. – Online Brokerage Solution Provider

• Placed most active files - including temp space and redo logs on the RamSan.

• Result: cut average latency by 67%, and doubled the orders processed per second

TMS Customer

Fox River Financial Resources

• The RamSan is used to rapidly acquire tick data in an oracle database for their proprietary modeling software that executes trades.

• The RamSan has allowed their system to maintain rapid response time irregardless of trading volume.

• A side benefit was that batch process run time reduced from 3 hours to 20 Minutes (6x improvement) with the RamSan

• Fox River Financial Resources Offers an order execution service to large institutional clients.

• Offers a better execution price than the Clients can achieve on the market, and profits by trading at better prices. Clustered Oracle Servers
