We use 1 build in gig port for cifs access, one for iSCSI (for testing servers), which i want to move away from and use both ports for CIFS (2Gb per controller)
I will be implementing VMWare on blades and want to use NFS for datastores but still want to keep iSCSI for physical servers. I have 2 HP ProCurve 2910al 10Gb up 1Gb down switches that i will use. So i have 2 2 port 10Gb cards that i will uplink these switches.
So, can i use iSCSI and NFS on the same switch?
If so do i have to use 1 10Gb port on a card for NFS and another for iSCSI, or can i use both for both?
Then on a switch side, do i have to use separate VLANs and separate uplinks and switch ports per each protocol, or can both iSCSI and NFS use the same VLAN and then i will be able to use any port as either NFS or iSCSI?
BTW, These switches will not be used for anything else.
Yes, you can use iSCSI and NFS over the same links, and I believe there is even a whitepaper *somewhere* on using iscsi and NFS over the same 10Gb links. I wouldn't recommend it over 1Gb links for a production environment, though.
Ideally storage-related IP traffic should be separated from non-storage IP traffic - so for me having 'general' LAN & CIFS separated from iSCSI & NFS (for ESX provisioning), but iSCSI & NFS using same paths is good enough.
Having said that, there is the TR-3785 document showing feasible approach with just a couple of switches (although pricey Cisco Nexus ones) & couple of 10GbE ports per ESX host:
