[Bioclusters] notes and pictures from a "wet lab baby-biocluster" project

I'm interested by your choice of setup.

We've got a cluster that bears a resemblance to this one, we have 30
IBM e series IU duals (older X330 Pentium 3 machines), a Dell
PowerVault 14x146GB U320 SCSI storage unit and a cheap Netgear switch.

Two questions:

1) One thing I liked about the e series is the KVM daisy chain
function; although I can see this is less useful for only 6 machines,
I'm wondering if you chose not to buy it or if they've stopped
offering this. It is great when it works, but it is very picky about
keyboards, seems only to work with Microsoft branded ones (not IBM,

 2) I take it that your application requires massive storage that
isn't particularly fast, hence the array of ATA disks. Or is there
something about the Apple that I'm missing? I would like to see how
its performance over fiber channel compares with an Ultra 320 SCSI
array controlled directly by the head node. 5.6 TB is an impressive
amount of storage.
