Hardware configuration: the server 12 gb of memory, 8 g client, server and client are ShuangQian card, writing (from the client to the server), small file under 2 g show soon 200-300 MB/SEC (perhaps because the cache), large file 120-140 MB/SEC, in addition to using the SMB protocol file transfer test completely normal, read, write is 220 MB/SEC, very stable, ISCSI is very unstable, read, and write a little big file speed is too slow,
Moreover LSI RAID card is 9280-8, I have a 512 MB cache, using the SMB and MPIO transmission, monitoring both the network card in the transmission, SMB is full, but each card Iscsi is only 50%, consult, slow slow Iscsi, speaking, reading and writing, especially reading, what is this situation, how to solve?
