I've been cautioned not to create huge LUNs on a SAN (ours is effectively 19TB) but I admit I'm not very knowledgeable about storage issues.
As far as application requirements, I need a 5 TB mount attached to a virtual machine where I can store data. This needs to be physically stored on the SAN. The virtual machine should probably run CentOS.
So, how do I do this? Do I set up RAID on top of multiple iSCSI targets? Is that a bad idea, and if not what does that look like to configure on a Linux box? How do I merge these multiple targets? We use VMWare ESXi 4.1, but I feel like this doesn't offer much benefit for this problem.
