first i try to explain my problem.
We configured an iSCSI Target with SLES10.3. We can write (20GB) from another Server to that Target over NW with eg. 400MB/s. Using the iSCSI Target.
Now we configure our ESX Server to use this Target as HBA. Create a VM on an NFS Storage, create a hard disk on this Target. Now we repeat the writettest. We're not able to get more than 100MB/s.
Why? Can we change something? If its normal, which element decrease the speed?
I spent much time to find a solution for this problem. But i find4 nothing helpful.
ESX Server (ESX 3.5 build 153875):
HP DL 380 G8, 32 GB RAM, 8 x 2,833GHz, NW 2 x 10Gbit Ports with CX4.
No Name Server / 8 x 500GB Raid 0 / NW 2 x 10Gbit Ports with CX4.
Thanks for helping, if you need more infos, write short info.
3.5 only supports 1Gb/s traffic on the VMkernel network ports (iSCSI and NFS). If you want to fully utilize a 10 Gb/s link, you need to update to ESX 4.0.
