I am looking for documentation or recommendations for configuration on my LAN to support SAN-to-SAN connectivity. We are in the process of replacing our SAN and adding a new DR SAN at a remote location. We have two (2) 3750Gs supporting redundant iSCSI connectivity between the servers and the SAN. The 3750s are interconnected via the stack cable with one being designated controller A connectivity and the other controller B. All servers have two connections one to controller A and the other to controller B. The controllers from the SAN are connected to the appropiate 3750 as well. All the SAN hardware is configured for a unique network and been completely independent of the LAN.
They now want to start implementing phase 2 where the production SAN talks to a second remote SAN (DR SAN).
My question starts with is there more to it than simply adding the dedicated SAN networks to the LANs as a VLAN? This makes the traffic routable but also seeable by they rest of the company. I am thinking that I also need an access list so these two networks cannot be access by anyother network in the company?
I have never done anythig with SANs and the tech we have from the vendor is not a network / switch expert. He just knows he needs the equivalent of a cable run between the two SANs. I also have to figure this out within the next week or so.
Anyone know of or have a reference to documentation that can get me and keep me on the right path? I have reached through the vendor to a different Tech to see if I can get better information. Connectivity between the two SANs will eventually be across an MPLS network but for initial setup and config connectivity will be through the core.
Thanks in advance ....
