Hi ... i've rescued a good few Raidtec CS3102 (obsolete) storage boxes from being tipped. Why, i hear you ask?  Well, maybe, just maybe i can use it. Each one has got 12 sata hotswap bays but the interface is sata->ultra scsi 320 (x2 outputs). Just out of interest, given that i know absolutely nothing about attaching 'extra' storage to unraid, would this be do-able as extra storage for an unraid server. Obviously i'd need a scsi card inside my server but would unraid be interested in seeing whatever is hanging off the other end? I've seen others attach via sas->sata but ultra320scsi??

Anyone any input? Must be some SCSI attached devices still out there.

Last time I used ultra-scsi is more than 10 years ago ...

Doubt Unraid will have many SCSI controller drivers, if any, I remember some time ago I installed a SCSI controller for data recovery on a SCSI disk and there wasn't a driver, had to use Arch Linux.

Thanks to the both of you! I'll stick a card in and see what's what then. The wiki suggests storage can be attached via SCSI so let's give it a go. Surely an Adaptec card should be supported? How can I check without hoping someone who does have a SCSI attached das can see this thread ... would be handy if it works.  How about SCSI to usb adaptor??

 

Just an update. Most of these das boxes power up just fine and I can get a web connection to their frontend. What I can't do however is check out the disk config because I'm missing a bit of software, now long depleted, called 'Raidtec Manager'.  Bit of a longshot but does anyone know whereabouts of said sw or have a very old archived copy on their box 😃. A bit off topic I know, but if I can get these working they will be used on unraid so there's my cover!

If Raidtec CS3102 use sff8087 connect disk blackplane, then try connect them by SAS expander would be a simple solution.

HI ... cs3102 is ultra320 scsi internally and externally i believe. Still need to disassemble and take  look.  Doubt v.much that there's any 'new' technology in the box. There are a couple of ultra320 to usb adaptors out there but, again, doubt they'd have the capacity via usb to do much.

Ultra320 SCSI is 320 MB/sec ... 12 drives ... even w/ 2 ports running is ~50 MB/sec per drive [if it can really share its bandwidth reasonably]

Just an update and maybe someone can give me some advice. The SCSI controller card is in the server and shows up in its own group but no drives are being seen? Would this possibly need some configuring "pre-unraid boot" in which case I'll need to dig out a monitor and stuff or should I be doing anything within unraid to see them? The unraid wiki seems to say that SCSI attached devices should be ok. The fact that the controller card was even being seen makes me want to get this working if I can ... cheers!

Is a driver being loaded? You can post the diags to confirm.

How can I check?

thought the same thing, we was in hog  heaven when the company moved to 320 on the servers. All them cheetah drives!

Here you are ... i'm not confident that unraid will be able to see these DAS attached files despite what the wiki says about supporting block level files. Just wondering if a win10 vm may be the way to utilise? The card is available for passthru. My VM skills are limited (very!) however and i'd prefer the drives 'see able' by unRaid of at all possible. Ta!

 

ps .. this is a small test microserver i'm using, completely empty aside from what i'm trying to achieve.

No driver is loaded:

Not really a surprise:

Unraid install strips all unneeded drivers/modules to keep it as small as possible.

Must be some scsi stuff out there using unraid, it's still available. i'll need to pickup info on vm creation then. What a letdown eh!

Maybe ultrascsi to usb3??

Never seen anyone using SCSI with Unraid, also don't forget it will likely only work with small drives, so IMHO not much point.

These DAS boxes take 12 drives so even at 'small' 2TB size thats a reasonable size box of disks to use as a backup medium. I've got 8 of these DAS boxes, all working aok yet not of any use it seems to unRaid. 100TB of viable storage i cant use. Heyho.

You can always make a feature request for LT to include that driver, they are usually good at including requested drivers, though since this one would be for a single user not sure, but it won't hurt to ask.

Might just do that, nothing to lose eh, thanks for your time as always.
