QNAP and 10Gig-E
on Apr 25, 2013 at 8:25:34 am

So, we recently bought two new MacPro systems for our art department, and instead of the Areca based RAIDs we requested, the IT department bought a QNAP NAS box.

I'm not sure of the exact model, but the QNAP has two 10Gig-E ports, and about 6 or the 16 drive bays populated. There are also now SmallTree 10Gig-E cards installed in each of the two MacPros.

Currently they are configured that I connect to the QNAP as a network share via SAMBA (cifs).

Won't I run into the 64bit quicktime bug where I can't write movie bigger than 2GB from After Effects?

If I'm editing in Premiere, will I run into conflicts if both systems try to edit from the same material?

I'm not sure what to expect as I wade into this new vista I've been provided.

I believe the QNAP uses an Emulux 10gig card. Is it compatible with the Small Tree card? Why are you using .smb? The QNAP supports AFP. You will experience the 2.15gig file limit in AE over an AFP (and maybe an SMB) network. Adobe fixed this in Adobe Media Encoder and Premiere, but I believe not in AE. NFS will work however without the 2.15gig file limit.

You do know that you can't add more clients to your system without adding a switch, right ? QNAP makes 8, 10, 12 and 16 bay models, they do not make a 6 bay model. the 8 and 10 do not have expanders, so you can't add more storage to these two models.

Hopefully, you will report your results.

I was trying to write that it was an 18 bay device with only 6 drives populating it.

I did a test today, I can use AFP instead of SMB, but NFS isn't available. I'll have to ask if it's available.

Yes, the 2.15GB limit is there, and I've read on one of Adobe's blogs that the fix will be IN THE NEXT VERSION. So I'll have to convince the company to pony up more money after just buying CS6 Master Collection in February.

Yeah, they are aware that they'll need a switch if they want more users. Right now, this is just for the art room where we have only the two main workstations.

All the Mac Pros in my AFP SAN installations have an internal 2 drive RAID-0 that's used as a scratch, to get around the 2GB export limit. export to the internal RAID, when it's done, move the file to the SAN. it's also nice to have to keep render files and other temp stuff from filling up the SAN volumes

Not a bad idea, and not unlike the days where you would have a separate drive, just for a Photoshop scratch disk. Thanks.

I ran Black Magic's disk speed test on the QNAP. I don't have the results in front of me, but the top read speed was around 900MB/s.

If you play back an animation codec Quicktime from the QNAP, you get some strange results. The movie will apear to play normally, and then speed-up and then slow-down. Up and Down, Up and Down.

I only learned about this recently. There is a special config file for the Small Tree 10Gig-E card that has been installed in the /ETC directory.

I was working with the QNAP on the two separate MacPros we have connected to it.

Interesting behavior: Both computers see the folders created on each others screens, but cannot see the sizes of the directories. Calculate File Sizes is turned on. Even and its variants don't help.

Directory and files will report "Zero Bytes" or other odd sizes. Only the machine that created the folder can see the actual size.
