The FAST Suite Dynamically Optimizes IO For FLASH 1st At A 64K Page Size

• FAST Cache

– Caches Data From The HDD Or NL-HDD Tiers In The Pool

– Operates At A Page Granularity Of 64K

• FAST VP

– Dynamically Moves Data Between Tiers In The Storage Pool

– Operates At A Slice Granularity Of 1GB

• Deploying Both Together Ensures Maximum IO Granularity

Getting The Right Blend Of Flash3 Fundamental Business Questions

• How Much Data Is Under Management Today?

�30 TBs

• How Much Is Your Data Growing Each Year?

�50% Y/Y

• How Long Does Your Data Stay Hot?

�60 days


How Long Does Your Data Stay Hot?


Calculating Net New DataNet New Is A Function Of Amount Of Starting Data And Growth

• 50% Of 30TB Is 15TB

• The Average Amount Of Data Generated Each Day:

– 15 X 1024 GB / 365 =42 GB per day

50% Growth Rate

30 30

Start Year 1

Calculating Needed FLASHFLASH Only Needs To Be Large Enough To Hold Hot Data

• FLASH Capacity:– 60 Days X 42 GB =2,520 GB

• Flash Percentage:– FLASH Capacity/Total

Capacity – 2,520 GB/(45 X 1024) GB X

100 = 5.4%
