So I have a SAN connected to VM hosts using a 100mb CISCO router. Apparently this results in a maximum data transfer rate of 12mbps, which is very poor.
There is full redundancy between the SAN and the hosts using 2 switches which are HP ProCurve 2910al 24g models.
I am lead to believe that these switches support some form of routing, so that essentially I could set a switch as the default gateway for the SAN Storage Processor A, and the second switch as the default gateway for the SAN Storage Processor B - is this correct and, if so, please can someone explain it to me like I am 5?
Essentially I want to utilize existing kit to get the best possible data transfer speeds between the SAN and my hosts.
Edit: a bit more info about the connectivity in the network:
SAN: 2 storage processors, A's IP is 10.12.0.2, B's IP is 10.12.0.3 Management network for SAN is part of the LAN range 172.17.1.0/24
VMotion and iSCSI traffic are completely isolated - there are two HP 2910al 24g switches that carry the VMotion and iSCSI traffic between the hosts and SAN.
We then have 2 Cisco switches carrying the LAN and VM management traffic on the 172.17.1.0/24 range.
At the moment, we have a router sitting there connecting the 172.17.1.0/24 to the 10.12.0.0/24 range so that we can manage the SAN. This effectively has 2 IP interfaces, one with the IP 10.12.0.1 and one with the IP 172.17.1.47.
The SAN and VMK ports have a default gateway of 10.12.0.1 (the router). We don't currently use any VLANs at all (in the entire network).
For background info, I took over the whole sysadmin team about 18 months ago. The infrastructure was/is old and I'm trying to drag it kicking into this century. We've virtualised, but i'm on the VCP course this week and it's giving me some real thoughts about best practise, leading me to believe the current routing arrangement is a huge bottleneck and is probably wrong.
