Why “Flash” MattersIBM Texas Memory Systems (TMS)RamSan OverviewWhy TMS?


1. Reduce DB and “per core” licensing 2. Improve application efficiency 3. Improve server efficiency 4. Increase storage operations efficiency 5. Lowest Latency!5. Lowest Latency!

5 reasons why RamSan is a “must” in every data center

What if you could…What if you could…


Low Latency: Do things faster

High Scalability: Do more things concurrently

Low TCO: Save money and boost value

Flash delivers performance and value to boost the applications running your business.

Are you still waiting for the 25K RPM

Business Benefits of Flash

Scale applications further– Do more things with more people/customers/etc– Increase "parallel" performance

Speed up applications– Do existing things faster– Increase "serial" performance

Create new applications– Do more things with data– More analytics -> more insight

Make applications more efficient– Do more with less spindles, CPU cores, license fees, etc

Variable Stripe RAID™ (VSR)

Patented VSR allows RAID stripe sizes to vary. If one die fails in a ten-chip stripe, only the failed die is bypassed,

then data is restriped across the remaining nine chips. VSR reduces maintenance intervals caused by Flash failures
