用 IB 唔一定有錢嫁,,只不過係配合各方需要

似係network 問題
NFS 本身就好大overhead，否則人家都唔駛出san 同iscsi 啦，
你呢個spec 早就要用san 或 iscsi 了

仲有，switching 同routing 有無set qos 有無bottomneck?
有無出現global synchronization的情況? file sharing 好常見的

NFS 係 application level, SAN/iscsi 係 block level 唔同野來 wor

係直頭改design 唔響network 度行file sharing，走類似vmfs 響上面行CLUSTER

ching 我中心思想是 nfs service 有 bottom neck ,點樣去排除 ,network 方面我覺得不是重点 ,因为我是行 cloud compting ,他计好數就行 Ib直落 storage ,direct attach 的

cloud computing? 但又 LSI raid 5 又 NFS, 又 IB?
不如你先將你啲嘢畫張圖解釋下先.

We use Isilion and the NFS performance is very good (3000MB/s) , NFS is just a network service to exchange file chunk , file system performance and design is more important  (eg, file seek time , caching, read write latency ) ...for storage sub system ,  using a cheap cheap LSI card will not give good result ... also RAID-5 read write latency is too high, normally if we want good I/O , we will use mirror
