Hi there.

I got myself a pair of old Intel Xeon blades, which I plan to
repurpose with CentOS.
The model is : HP bl20p-g3 server blade

Now, the main problem with this hardware is that LVD UW SCSI HDDs are
hard to find and hella expensive if you find em (and of reduced
capacity).
Any of you know:

1. If there's any third party maker of any daughtercard offering SATA
ports? The main board of the system has daughtercard sockets allowing
for instance SFP ports

Seems to me that there'd be a small but interesting niche for this
kind of adapter.

2. If it's possible to use BootP for booting off a network drive?
I know there are some UWSCSI to SATA adapter daughtercards but those
sell for $250 which is way over my budget.

So, if you had one of these blades but not any UWSCSI HDDs what would you do?

Thanks in advance for any pointer. This hardware is too good to back
to the dumpster where I got mines from...
