scsi-2 and scsi-4

Mquinn6 — Mon, 10 Apr 2006 11:31:37 GMT

I am attempting to increase the capacity of a development server (HPD310) and have noticed the largest HVD 68 pin scsi2 drive available is 18gb (and they want a pretty penny for it!). Everything I read indicates that I can put a LVD 68 pin scsi4 Ultra320 drive in the hot plugable module and it SHOULD work. This is only for development and would NEVER be used in a production live envionment. Some of the information I am using is http://www.paralan.com/glos.html and a very good conversation with Andrew at http://www.cablestogo.com/resources/scsi.asp?

I am planning on using a ST373207LC
73GB drive and understand my limitation would be the performance - not the capacity (which I am seeking (no pun intended)).

Has anyone done this?

I haven't done it on a D310 although I hace used a BlackBox LVD/HVD SCSI Bus Converter on a D380. As long as you are not using this as a boot disk, I see no problems and the fact that you disk is not an HVD SCSI device should be completely invisible to the host. I have used the converter for both disks and tape drives on a D-box.

It is hard to justify a 750 dollar Ultra2 SCSI LVD/HVD Multimode Expander by black box to add drives to an old D310. Anyone else have any luck with this?

hi,

yes it can be done, but with caution.

Not all the HP caddies have the same adapter in them and will not work, its trial and error really. I would avoid using u320 disks aswell really and stick to u160/7200 at the most. This is as the newer disks do get alot hotter and could overheat. u320 disks usually run at 10k/15k rpm.

I would open the caddy and look at the disk already in, go to the disk manufacturers web site and look at the specs. If you have a disk that is a se scsi-2 disk then it will most likely work. If its a Wd scsi-2 disk inside then it wouldnt.

try and contach jesse in this thread for more help, he may sell you some already made up or tell which drives they use

The hot plugable drives in the HP D310 are DF drives which thru further investigation - LVD is backward compatable to SCSI SE not SCSI DF. The thought is to use
http://www.ramelectronics.net/catalogbyProdID.asp?prodid=460I-2CN80MF and replace the tape drive which is SE with the Cheetah drive. Anyone else have their fingers crossed?
