Sorry for the double-post, but another thought if it's not obvious already: with such a large dataset, making sure to employ striping and high-RPM disks will be important for speed. I'd recommend looking at RAID 1+0 with dual SCSI channels and 15K RPM disks if you're looking in the Dell PowerEdge series. The more disks you can stripe across, the better (to a point of course). Multiple SCSI channels help too. RAID 5 is pretty effective too for read speed.

Hi, I have a table (structure below) which will hold 2.5 billion rows. I'm currently choosing the hardware i'll need. Does anybody know what the minimum spec of machine is likely to be that I comfortably use? I imagine the table will have to be Innodb split across a number of files. It will also need careful indexing to be able to access with rapidly. I was thinking of something along the lines of the Dell PowerEdge 1950 or 2950?
