Hi,
for a specific application we need a low-profile SCSI card (PCI) with external 50pin connector. I thought about getting an "Adaptec SCSI Card 2930LP". However I was not able to find any usable information about wether this card is supported by Linux/CentOS 5.x or not. Does anyone have this card working with a CentOS 5.x machine?
Alternatively: Are there any linux-supported low-profile PCI SCSI cards with 50pin connector which are supported by CentOS 5.x and which you can recommend?
Thanks in advance

ALL Adaptec SCSI Cards (except for a few bleeding edge 64-bit PCI cards) are supported, out-of-the-box using stock kernels on all versions of CentOS (3.x, 4.x, and 5.x):
On my CentOS 4.8 box:
sauron.deepsoft.com% strings /lib/modules/2.6.9-89.0.16.EL/kernel/drivers/scsi/aic7xxx/aic7xxx.ko |grep 2930 Adaptec 2930CU SCSI adapter Adaptec 2930C Ultra SCSI adapter (VAR) Adaptec 2930 Ultra SCSI adapter Adaptec 2930 Ultra2 SCSI adapter
And in a CentOS 5.2 install:
sauron.deepsoft.com% strings /CentOS52/lib/modules/2.6.18-92.el5/kernel/drivers/scsi/aic7xxx/aic7xxx.ko | grep 2930 Adaptec 2930CU SCSI adapter Adaptec 2930C Ultra SCSI adapter (VAR) Adaptec 2930 Ultra SCSI adapter Adaptec 2930 Ultra2 SCSI adapter
It is supported.

Go with the Adaptec card.
Thanks in advance

Except that nowadays, some cheap desktop-motherboards may not know how to enable booting from such a card. It's years since I used SCSI-drives for desktop-use - and then it was a workstation-class Dual-Xeon board, Socket 604. So I can't say if this is still true today - but I've read that people have problems like that.

I seriously doubt a SCSI card with a 50 pin (max 10 or 20MB/sec?) external connector is going to be used as a boot device. more likely, this is for some older tape class device like a DAT.
btw, the original poster should know, you can convert wide (68 pin) SCSI to narrow (50 pin) SCSI with a 'half-terminator' cable adapter, such as http://www.ramelectronics.net/computer-parts/scsi/scsi-adapters/hd68/hd68-hd... (random google hit, I know nothing of this vendor)... this terminates the top half of the scsi BUS and passes the low half through. All SCSI controllers support narrow devices by design.

Almost right. No booting from this card is required. It's for the connection to a X-ray data collection system.

I've been told by the vendor of the said X-ray data collection system, that 68pin connectors "never worked with Linux" for their device.

I *suspect*, given the OP's specific request for a 50-pin external connection that this is for something like a scanner or tape drive, not an internal boot disk.

Great & thanks

I'll use this string search next time I'm looking for device support. I didn't know I could do that.
Greetings from my host (balrog) to your's :-)
