very high latence when start 10 VM
hi
i have create replication node with iscsi failover
when i start 1 VM , all is ok , latence (VM reporting) is under 20 ms
but when i start 10 VM latence up to 1500 ms ! and i need up 1 hour to start all VM
actualy i use 1 nic (GB) for iscsi
on my NAS i have raid 5 with SAS disk
and i use hw raid Areca ARC 1880
i need to restart vm for my trainning class
you have an idea to get better result.
Regard Sebastien.
With 1 NIC for the iSCSI Auto Failover is not recommended - see link below as you need a dedicated NIC for the Volume Replication.

Also make sure the Write Back Cache set on the controller?

Hi ,
i have 1 nic for isci
and 1 for replication
and one for management
yes write back is enable
Any chance that you can get another NIC and use the MPIO with VMware?

What was the Bandwith settings for the Volume Replication set for and how many volumes are you running in the task?
All the best,
