We had the direct attached in the beginning... then reconfigured it. I need to search my brain why it was not working right.
I also need to present the LUNs to our Backup machine (external Proliant) to perform faster backups and do not have pressure on the hyper-v hosts.
I do not think that we a have a 4 port controller in our 3Par. So i need to buy one anyway if i proceed with FC.
If i have a dedicated 2 port 25gbs card for the storage in each server - how could be my best configuration for this?
Well, there is no onboard ports on the 3PAR for iSCSI, and if you’re going for cifs thru File Persona (which isn’t recommended for virtualization) you would be limited to 1Gbit onboard RCIP port (also not recommended). So either way it seems to me that you either need to get additional HBAs for the 3PAR or continue with FC switches.
If you’re going for iSCSI you should have switches designed for iSCSI with DCBX and if you don’t have that it will also add to the cost on top of the added complexity over direct attached FC. neither iSCSI or File Persona supports direct attach.
Based on what you’ve posted I assume you ditched FlatSAN (not direct attach) because you ran out of ports, and based on the info provided I don’t see a cheaper and less complex way out of this that direct attach.
