stability of iscsi on hardy

[Simon Croome]

we are currently have 4 production VMware ESX servers and 2 Disaster 
recovery servers again running ESX server,
have not had chance to look at Xen but I have read some quite exciting 
things about it, my only other bit of advice using open-iscsi would be to 
make sure
that you use a RAID 10 for your disk layout as RAID 5 reduces performance 
greatly and when using a VM environment disk performance is key.

I would also recommend using gigabit networking loopback for communication 
between your servers and the iscsi unit as network throughput can suffer and 
also security can also be an issue although I'm using iptables to protect 
our iscsi units.

Hope this helps, Simon.
