VM Direct Path - NIC teaming (VMDirectPath I/O pass-through devices)
Quesion on if this will work and if it's sensible.;
Software: Running ESX 5.1 U1 (standard licence so no dVSwitches)
Hardware: HP ProLiant DL380p, 3 x HP Ethernet 1Gb 4-port 331T Adapter
Problem/Issue: We need to backup some large exchange VMs via the network to a physical TSM Server.
The physical TSM Server has 4 teamed NICs and is on an ether channel. We need to aggregate the bandwidth on the ESX / VM to get faster backups from point to point.
The Hardware is connected by cisco 2960x switches
The plan is to configure the VM to use VMDirectPath I/O for one of the 4 Port adapters and configure it with HP NIC teaming software.
Would this work?, Ie, would the possible bandwidth be increased from/to the VM ?
Would the bandwidth be increased specifically for the TSM backup traffic - I'm thinking of IP/MAC hashing and the fact that its a single application and it is a specific one to one connection. (I guess i'm asking would it still just use one port in/out of the switch/VM as it's a one to one mapping (ip and MAC) rather than a one to many mapping.
Unfortunately my comms knowledge is not great - hence the above question.
Any suggestions welcome - shoot me down in flames also OK.
