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.

It is actually fine, but its recommended to set rule at your storage so that only esx hosts can see vmfs LUNs

Exactly. I would use the iqn names to allow access to the LUN's to their respected machines.

Thanks for your help, I'm going to leave this open for a short bit to see if anyone else has anything to add.

Thanks!

It is as "ryder" described. Configure as you commented above and you should be golden.
