If I would be running Solaris on my boxes I would do just that (notice that I have only 2 SATA slots on the system, so there's no space for another drive once you go RAID 1). However, as a vserver user, my options are limited to the fs that Linux natively provides. So no SSD caching for me, until btrfs goes production, and actually can deal with SSDs intelligently. > Something like: > http://www.kingston.com/ssd/kc100.asp > > Which would (in the 120Gbyte size) run you about $2/Gbyte and > give each client machine a local 90K IOPS cache in front of > your old server network connected at only 1Gbs. > Caching locally about 5% of the network data would greatly > reduce your network load. > > Unless you can upgrade your networking to 10Gbs fiber, I think > this would give you about the next best performance. > > Mike > > I think I'll go with an NFS.
