如果只需要 FastPath 用于 SSD RAID 0，只要用普通版 PERC H700 就行？

Boomer

不需要 CacheCade 之类的高级功能~

PERC H700 1g版本的还是好些

价格要贵 1/3 以上…

1g nvram的需要多少钱啊

要確認很簡單..
看tty log..
查看MFC設定..
只要確定CTIO打開即可..

Dell是把FastPath和CacheCade捆綁在一起的

根據我檢查512MB版本的tty log..
CTIO並沒有被關掉...
只有SSCD被關掉..

早前實測過512MB的版本，IOPS被限制在10萬以下

你有確定CTIO是開的??...

看我之前H700的测试成绩 IOPS到16W了啊  我的512M版本的

看了 TTY Log，确实是 CTIO 已经打开~那么就可以肯定，512MB 普通版本的 PERC H700 是带有 FastPath 功能的了？

4K-64thrd 可以跑到 150000 IOPS…

就我所知是這樣..
例如未使用FastPath的9260-8i..
CTIO是關的..
使用FastPath後..
CTIO=1會開啟...
CTIO就是dell Tech. book講的Cut-through I/O技術...
也就是LSI的fastpath..

畢竟tty log是f/w log..
MFC的設定是來自f/w初始化載入的...
應該是不會有失準..

嗯~看来 Dell 那是相当厚道，哈哈~
