Mixed enviroment with VMware & MS SQL Clustering w/ iSCSI
Posted on 2010-01-11
I have a question about mixing an environment with my current VMware layout and adding a MS SQL clustering to it.
I have a blade chassis that is running 3 blades with ESX 4.0 going to my iSCSI SAN. Those connections are using Jumbo frames (9000 MTU on the VMware side & 9252 MTU on the switch side). This network is isolated only to the VMware host and not the internal LAN's.
My question is, I want to add 2 more blades to my chassis that will run Windows Server 2008 R2 that will be a SQL cluster. I would be planning on using the MS iSCSI initiators to connect to the existing SAN (as above) and I wanted to make sure that this wouldn't cause any issues with VMware and/or with the MTU rating that is currently set to jumbo frames.
