HP A3311A Jamaica Deskside Box and cluster under Linux

all gurus here:

I have been searching for months for a HA array that support access from 2 hosts, in order to build a cluster testing environment at home. (array like HP's xp256, SUN A1000/D1000/a5200). This HP Jamaica array come to my mind, here is the question:

1) If I put in a HVD scsi adapters (as the array is running on DF disk) to each PC, can 2 hosts be able to access the array from 2 PCs running on Linux? any additional driver for the array required??

2) anyone can recommend any HVD adapter for PC, other than AHA-2944 and AHA-3944 (which I may need to look for driver, as there is not any Linux driver from Adaptec)

3) any one have any idea what kind of SE/HVD SCSI this Jamaica array have? as I see there are so many type of HVD SCSI connector, say Fast Wide, Ultra SCSI, Ultra SCSI, Wide Ultra SCSI,

like to know suggestion from all the experts here.

as a result of discontinued product, i can barely get any documentation from HP's web site. Suggestion in any form would be deeply deeply deeply appreciated!!!

See this link:

That unit is an SE single ended SCSI device.

Most adaptec scsi cards will be detected automatically by the Linux kernel. There is no need for drivers.

Just pick one that handles single ended scsi, not LVD.

thanks for the reply, i know A3311A would have 2 type of SCSI connector SE and differential (believe should be HVD instead of LVD), depend on the actual disk used. in my case, the disk listed as DF disk, so i believe is differential . correct me if i am wrong.

You are correct.

Definitely not LVD.
