曹圖強(qiáng):There are 2 major protocol today in IP storage, iSCSI and FCIP. Typically, features such as, DH-CHAP, IPSec will provide the secured storage network and compression offers customers with large data transfer at limited bandwidth. For example, at 2:1 data compression, turn on compression could provide a effective throughput at 2 x bandwidth. Hope this answer your questions.
