5. 傳統磁碟機將不足以滿足IO需求
Moore 定律驅動著CPU的快速進步，也鞭策著存儲IO須同步增長

6. CPU與HDD速度差距越來越大
CPU增進神速，每十年加快100倍 – 磁碟機無法相比
CPU Continue To Improve
MOORE’S LAW: While Disk Drive

Performance Remains Flat.
As A Result, Applications Will
per Suffer More And More Unless
We Rapidly Move To FLASH.

10. EMC FAST 軟體組合包
以64KB 與1GB 為單位 優化IO
• FAST Cache
FAST Cache - FAST VP Relationship – Caches Data From The
HDD Or NL-HDD Tiers
Controller – Operates At A Page
Granularity Of 64K
• FAST VP
– Dynamically Moves Data
FAST Cache Between Tiers In The
Storage Pool

11. IO曲線例子
與資料成長趨勢, 與AP模式相關
Growth: 50%
Very High Growth: 60% Std. Days Hot: 60
Days Hot: 10
Skew 5.5% Of Data = 80% Of IO
Skew 1% Of Data = 80% Of IO
Growth: 100% Growth: 50%
High Days Hot: 30 Low Days Hot: 90
Skew 4.2% Of Data = 80% Of IO Skew 8.2% Of Data = 80% Of IO

12. 需要多大FLASH空間?
FAST 軟體機動地使用FLASH空間
• Data Follows A Predictable
Size of FLASH FIFO Decay In Activity

Highly Active Data
• The Amount Of FLASH
Required Is Determined
