This comment doesn't make any sense to me, would you care to expand? If you're suggesting AoE and putting the OS and temp/scratch/swap space all on centralized storage ... Then we're talking a single Ethernet bottleneck for all machines. It may give the flexibility of relocating a virtual server from one hardware to another, but at the expense of diminished performance compared to local disk. Here's what I have: A dozen or so compute nodes, which all do heavy temporary disk IO, compute and memory intensive jobs, while under load doing batched jobs. To alleviate the bottleneck of centralized storage, there are two solutions: SAN with nonoverlapping LUNS on separate physical disks, or local disk. The local disk is a lot cheaper. The only thing I see to gain with the SAN is the ability to VMotion or Live Migrate to different physical hardware, which is an unneeded feature in our environment. _______________________________________________ Tech mailing list [email protected] http://lopsa.org/cgi-bin/mailman/listinfo/tech This list provided by the League of Professional System Administrators http://lopsa.org/
