hi,

i found my old post, finally i found the trick in vmware thant i neved posted back here...

In fact, we just have to change the round robin policy (iops options). I assume that you have MPIO working (multiple connections from 1 host to 1 lun)
First, activate round robin in vmware (Manage Path on Datastore) then connect to ESX Host with SSH

list vmfs disk on esx host :

ls /vmfs/devices/disks/eui*
/vmfs/devices/disks/eui.65304753474c3552
/vmfs/devices/disks/eui.65304753474c3552:1

get current config:

/usr/sbin/esxcli nmp roundrobin getconfig --device eui.65304753474c3552
Byte Limit: 10485760
Device: eui.65304753474c3552
I/O Operation Limit: 1000
Limit Type: Default
Use Active Unoptimized Paths: false

modify iops option

/usr/sbin/esxcli nmp roundrobin setconfig --type "iops" --iops=1 --device eui.65304753474c3552

verify option

/usr/sbin/esxcli nmp roundrobin getconfig --device eui.65304753474c3552
Byte Limit: 10485760
Device: eui.65304753474c3552
I/O Operation Limit: 1
Limit Type: Default
Use Active Unoptimized Paths: false

with this config done on all my Host for all my datastore i get 170 - 180Mps in read performance with 2X1Gbit.

Now my last question, can i have the same config with iscsi failover, i just need 2 virtual ip

Thanks

This is correct that you will need 2 VIP's to work with the MPIO.
