iSCSI Performance
I'm looking at the performance of our SAN.
We created a new Windows 7 guest with no fragmentation to the disk files and we are getting the speeds below.
Can anyone suggest the average speeds we should be seeing?
Our Equallogic is a PS4100 which has the 1Gbps network interfaces.
LAN and iSCSI traffic are in separate VLANS.
Thanks

What kind of setup do you have?
- Hypervisor?
- how many network cards on the host for iSCSI?
- is the test being run on the guest's hypervisor-provided disk (vhd,vhdx or vmdk) or a raw disk or guest-attached iSCSI?
- if guest-attached iSCSI, is the guest piggy backing the same NICs for iSCSI that the host is using for iSCSI?
- how many and what model switches for iSCSI? Are these dedicated to iSCSI or also being used for other traffic (LAN, VOIP, vMotion, heartbeat, etc)?

Thanks for your response.
The hypervisor is vSphere 5.1.
The host has 2 x 1Gbps ports for iSCSI
The guest disks are vmdk files which are stored on the Equallogic.
Our server is an Intel Modular server which has two inbuilt switches for redundancy, the Equallogic has a 1Gbps connection to each switch. The Intel swiches are connected into a 3 port trunk in a HP Procurve 5406zl. iSCSI and LAN traffic are in seperate VLANS. We don't have a dedicated switch for the iSCI traffic.
Thanks

Thanks for the info. I'll compare our setup with the documentation.
