Yes, I own such a box. I hate it a bit. Why? - rather low pricing, but lots of anti-features: no snapshots, no virtual disk copy, no "performance tier" (yea, they really slow down the box intentionally and you have to buy for releasing the brake). Pay about 4k€ extra to have a working SAN. - only 10K SAS disks available for 2,5" - Bad connectivity: 4x 1GE only, 8x1GE possible, but only one storage controller can be active AFAIR; if you have 24 SAS disks in there, it's a bad bottleneck IMHO - I dislike the many multipaths, two times 10GE would really be nicer - only one iscsi target. You have to do funny lun rescanning all the time, which is doable, but if you don't take very good care when removing the iscsi LUNs and if it's still in use by multipath, it can crash your complete box (still analyzing why); also you cannot have two iscsi targets for two network zones (production/testing) for better separation - bad performance, the local 2,5" SAS 15k disk brings twice the performance the SAN. Still searching why, maybe I'm writing something about that later. - I really hate the windows interface, an integrated webserver would've been nicer (that's personal taste only, and yes, there is still the CLI) I'm still in the process of setting this up, but I don't like this box at all. I'd really like to test an Equallogic as replacement but Dell (or rather our reseller) doesn't seem to be willing to take exchange, even if we buy a much bigger equallogic.
