Can't use SAS SSD for storage with a QXP-12g2e (SAS-12G2E)

English Storage

I can only use external SAS SSDs for caching not for storage with a QNAP QXP-12G2E. If it works for caching there is really no valid reason to disable their use as a simple storage pool.

2

You mention a SAS card, but not the actual host for the card

3

The card is intended only for the expansion enclosures. That may be why the NAS isn’t recognizing the HDD.

4

But OP mentioned they can use it for caching, so it must be compatible on some level.

5

It’s a TS-673A with 32GB of RAM, 6x 8TB SATA Seagate IronWolf + 2x 1TB NVME Samsung 990 Pro. I can configure the external SAS drives as Cache, but now I could prove they work by relying on a workaround of assigning/dedicating the QXP adapter to a virtual machine and now I run an Unraid that sees all drives and it can access it all, so yeah, the drives and the hardware works, not just with Qnap natively for creating/expanding QNap volumes which kinda sucks.

That card does not show up on the compatibility list, just the SAS-12G2E

7

Yes it is that card, I was just going with what the QNAP GUI gave me but it is a SAS card

I would say open a ticket, if that card is on the list without caveats (like min BIOS version etc) then it should work.

I would love to purchase a QNAP genuine “home” SAS enclosure like the QNAP REXP-1000 Pro but it’s not available anywhere (not even used). QNAP REXP-1000 Pro | QNAPWorks.com So yeah QNAP forces options that don’t exist and artificially blocks anything else, and no I won’t install the rackmount options that have very noisy fans and that are very bulky and clearly not made for home use.

Thanks, I was considering this. Will do it this week to see what they can offer supportwise

11

Oh, so if it’s not used with a QNAP enclosure, the ticket might not do much.

I think the only 3rd party enclosures QNAP supports, are some Segate EXOS JBOD’s

It’s nice to know it’s an option but I can easily find Rackmount SAS enclosures from QNAP used (quite cheap too) like the REXP-1200U-RP or the REXP-1600U-RP but… …from what I have read they are super noisy and meant only for datacenter uses and not for home. It will be sitting 12 inches from my head as I type this, so noisy options are out of the picture unfortunately. Although I’m curious since it’s the first I heard about third party options, does QNAP have a list of all the compatible options out there ? I could certainly check out such a list for options I had not considered before.
