Good evening,
After a horrid experience with Vmware's VDR, I've downloaded a trial of Veeam and am playing with it. We use an Iomega StorCenter as our backup device in iSCSI mode.
My question is whether I should make a virtual disk that uses the StorCenter and add it to the Veeam server or whether I should use the software ISCSI initiator in Win2k8 R2 to connect to the Iomega directly?
Thanks very much,
Chris

Re: iSCSI Storage Configuration for Veeam
Hello Chris, I do not really understand the first option, but second option is the correct way to configure Veeam Backup server for direct-from-SAN backups. And there is another way too, if your Veeam Backup server is installed in a VM, you could use vStorage Virtual Appliance processing mode - this does not require any additional configuration at all. Thanks!

Re: iSCSI Storage Configuration for Veeam
Our ESX hosts have local storage, not SAN storage, but our backup device is the StorCenter. I've put one VM on each ESX host and installed Veeam on it so I can use virtual appliance mode on both boxes. Performance is pretty good.
If I understand things correctly, there are two ways I can configure the iSCSI drive for Veeam to use.
1. I create a new virtual disk on the iSCSI datastore and mount that disk in the virtual machine. All done through VMware.
2. I use the Wink28 iSCSI iniator on the VM to talk directly to the StorCenter.
I was wondering if there was a preferred method.

Re: iSCSI Storage Configuration for Veeam
Thanks for clarification, I get it now. I did not realize you were talking about backup target.
In terms of performance, option 1 is preferred method. ESX4 has completely rewritten iSCSI initiator, and VMware had put a lot of effort in it. Very fine piece of software, nicely tuned and will beat the one found in Windows any day hands down.
I do not mean to say that Windows software iSCSI initiator is horrible, not at all - it is pretty solid - just not the best performance, and Windows getting in the way with its strange TCP "optimizations".
