I need to add a second SAS Tape drive to my server. I have a second PCI-E SAS card, however I don't have any free PCI slots in the server. Is there any way to daisy chain external SAS devices together from a single external SAS port? similar to the way external SCSI works?

Look at your SAS tape drive(s).

Do you see one SAS port or two SAS ports?

If you see one, you don't have any options to daisy-chain.

  • Thanks. Yeah, that's the beast. Only one port. I was hoping there was multi-lane external SFF-8088 cable option or something that I just wasn't finding on google. Feb 27, 2015 at 15:19
  • You could buy a second tape drive specifically with both ports and leave this one at the end of the chain.

Certainly SAS does support daisy-chaining but obviously individual products don't have to support that if they don't want. So it all comes down to the exact products you have, if you have a device that has both in and out ports then I say go for it - it won't be too hard to try and if it doesn't work you'll know about it pretty quickly.

On a separate note I can't believe you've been allowed to have that user namer on here for so long - would you consider changing it please as it infers some form of officiality that's not the case - sorry to be a pain about it but I'd sooner you change it than the admins.
