Open-e has been very stable fast and efficient for me. It puts extra ram to good use for read cache and can handle loads with minimal effort from the CPU. If these are existing VM's or Physical machines that you are planning on placing on an open-e storage platform. I would recomend gathering statistics on storage performance from them via perfmon or an aporpriate tool for your enviroment. Once you know more about your I/O work loads you will in a better position to decide what you need for hardware.
I am running about 10 VM's via Xenserver. All except a SQL server are running off of ten 1 TB WD RE3 in a Raid 10 Configuration. This supports a typical Infrastructure for about a 100 work stations. But this says very little about my acutal work load.
Iometer Testing for my Open-e Server from a Windows 2003 Server VM hosted on xenserver:
8k Random IO 70% Read 30% Write ~8000 TPS sustained.
64k Sequential Reads 200MBps (Mega Bytes)
64K Sequential Writes 90 MBps ( Mega Bytes )
My numbers would be better but my Drives are in an external array and the cable lenght made Sata 300 unstable so they are throttled down to Sata 150. The above test also were taken with all of my VM's and users active so they are my available capacity while in use.
Good luck with your project let us know more about your work loads if you would like more input.
