Looking at my Sun SB2500, I'm thinking of ways to make it less noisy and
less power hungry and one of the obvious ones would seem to be replacing
the 10k SCSI drives with some SSD.
The mechanical problem of getting everything mounted I can deal with.
But what I would like some advice on is which PCI cards are well suited
to being mounted inside the SB2500 and that will support booting from SSD?
My sb2500 boots from a CompactFlash card in an adaptor plugged into the
unused onboard ATA port ( the other one is hooked to the DVD drive ).
It's only UDMA33 but just for loading the kernel and a rescue system
that's more than enough. For everything else I have a 500GB SATA-II
disk on a Silicon Image PCI-X card, sitting in one of the 66MHz slots
so there's plenty of bandwidth to go.
The adaptor is ~$5 at monoprice, the SATA card was about $20 or so.
