Hi,

I use the Equallogic AutoSnapshot Manager to replication from my primary SAN to my secondary SAN.

Due to the nature of the network infrastructure, the iSCSI traffic has to traverse my core network switch to get accross the WAN to the secondary SAN.

The iSCSI traffic is VLANed on all the switches but is currently routable between network and iSCSI VLANS.

Is there any need for routing between these VLANS? Does the ASM require this? I'm just a little unclear as the communications path.
I'd like to completey isolate the iSCSI network for security and integrity.

Any comments, tips or pointers to articles I've missed would be appreciated.

Thanks
