Veeam backup - iSCSI - Lefthand

[murda]

Hi all,

Can someone enlighten me?

We have a physical backup server which is a E5606 Quadcore@2.13ghz - 8GB RAM running Windows 2008 R2. Storage for the backup is a sas connected DAS (12x1TB SAS disks)

Our virtual infrustructure is running vmware on multisite HP Lefthand P4500.

Now i've target the vmware luns as read-only luns to our backup server.
Veeam proxy configured as "direct san access" and this is working ok. ( 50-75% is used 1GB iscsi)

I have 4 HP NC365T networkadapters which can be used for iSCSI backup. (atm I only use 1)
I cannot use the HP DSM MPIO for the lefthand on our backup server because of the LUN locking issues with VMware...
Is their any way to use the 4 network cards in MPIO with iSCSI? Without messing up our virtual environment?

Thanks,

[murda]

These threads are summing up my problem

iSCSI configurations with v6 Architecture
Veeam with HP P4500 San IQ

side question:

What If I wanna build 2 extra VM proxies.

Should I go with a network card in the LAN environment and then on my physical backup server team 2 LAN adapters. (Configure proxy as Hot add)

or

Should I go with an extra network card in the iSCSI lan and then on my physical backup server add another network adapter in the iscsi network. (configure proxy as SAN BASED)

Which option is preferred or the fastest?

Hi,
we use Lefthand in our datacenter and we always used hotadd mode. We can reach 110-115 MBtis which is really near to 1 gbits connection limit. I tested also san mode but having many ESXi and luns, is way too simple to configure lun acl only once for the ESXi and use then hotadd.
About MPIO, have you tried the native Microsoft module? It's well documented, used it few times at customers but it works (http://blogs.technet.com/b/migreene/arc ... 77914.aspx)

PS: you can use hotadd mode only via virtual veeam proxies, not on physical veeam servers...
