I am getting dismal performance when copying to or from my ISCSI SAN.
My copy speed is averaging around 20MB/s. This seems quite slow by ISCSI standards.
Hardware is listed below:
Dell PowerEdge 2800 with 2 Intel Pro/1000 PT Server adapters dedicated to SAN.
(Windows Server 2003, SP2, 4GB RAM)
Dell PowerConnect 5424 switch.
IStor IS325 ISCSI SAN.
I am using MS ISCSI Initiator 2.08
I have taken the following steps in an attempt to improve performance:
Checked the "Enable advanced performance" option in the drive policies.
Enabled Jumbo frames on the NIC's, set to 4088.
Enabled Jumbo frames on the switch, no place to specify MTU size.
Enabled Jumbo frames on SAN LAG, set to 4088.
Flow control is set to Generate and Respond on the NIC's.
Flow control is enabled on all the switch ports.
Spanning Tree is disabled on the switch.
At the SAN, ports 1 and 3 are grouped in a LAG (Jumbo frames set to 4088)
Any help is GREATLY appreciated.
