QNAP performance

[Bruce123]

Hi all,

 

We have a QNAP used as an iSCSI target and a user/customer is experiencing performance issues when using InDesign to load and save files (like 60 second delay when opening or saving or worse)

 

But when we/they do a test transfer of a large ISO file (to and from) we're getting close to 1Gbit transfer rate (and the total sign of the InDesign file including images etc. isn't that big).

 

So we're not sure what the root cause of the performance issue is or how to address it.

 

Currently the link from the HyperV server to the QNAP is 1Gbit Ethernet cable (not going through switch) and we plan to replace this with 10Gbit. But having checked the utilisation of the port, it never seems to max out, so I'm not certain this is where the bottle neck is.

 

The QNAP TS-EC1280U is fitted with 12x 8TB HDDs as RAID 6.

 

I am wondering if the issue is with the QNAP itself and it just doesn't have the performance (IOPS, memory, CPU, effective seek speed) to meet their requirements (at least how it is currently configured RAID, HDDs etc). When the user saves locally or to a VM hosted on an HP SAN, they don't experience any issues (but we don't have the space on the SAN to store the files there - 7TB required).

 

Any advice would be appreciated?

 

Kind Regards,

 

Bruce.

We use a few QNAPs and apart from one having a faulty mobo that burnt out some RAM, we have not had any issues. A few things you may want to check, is the firmware up to date, is the firmware up to date for the nics and last one is, did you setup the storage on the QNAP asBlock-base Think LUN?

We also noticed that we needed between 32GB and 64GB or RAM if we was doing a lot of read rights to the drives to keep the speed up over time.

How big are these indesign files each roughly, and are there multiple users accessing InDesign files at the same time?

 

It it's 8tb hdd in a raid array then the performance is not going to be spectacular as these HDDs are significantly slower and less responsive than the modern SSD drives that would usually be used as local storage on these types of PCs.

 

You may find that the NAS "feels slow" just because is not SSD storage and everyone is so used to SSDs being instant nowadays.

Depending on age / model of QNAP device, you can add an SSD storage layer to act as a cache to speed up some read / write operations.
