Synology DiskStation DS713+ transfer speeds
-
I was at a client site where they were complaining about speed on the CAD stations. I asked them to show me what was slow, and it came down to file open and save operations. I checked in to that and found out they are saving to a rebranded Synology DS713+. The transfer speeds I was getting was 15MB/s. I looked it up the specs and it says it can do 202 MB/s read. It's only a two drive unit. Is it possible they mean it can do that with an expansion unit, but not with a single spinner?

RAID 0 or RAID 1? Is all the cabling good? Switches? Gigabyte Ethernet I assume?

I have to have the vendor give me access to the Synology.
They had 4 CAD machines and some mills connected to a 8 port NetGear Gig switch before going back to the Unifi switch I put in months ago. I wanted to test the line, but they didn't want to knock everyone off and kill the jobs they had running. I told them to let me know when I can get a maintenance window.

@mike-davis Did you test speeds directly from the Unifi switch?
-
@mike-davis If they have 4 users writing a million smaller files at once I can definitely see it bogging down to an average of 15 MB/s with 2 spinners.
-
Ah, you're talking about reads, I can get 90Mb/s on my super old DS213j with 2 spinners copying a single large file, writing to an older laptop with a 7200rpm drive. 15 definitely seems slow.

Good call. While I was onsite, I left when they didn't have creds to the Synology, but when you said that I realized I have access to the server and that had a drive mapped with cached creds, so I repeated the test from the Synology to the server which are both directly connected to the Unifi switch. The transfer varied from a max of about 70MB/s to a low of about 5MB/s. Average was in the 40MB/s range.
Write speed of the server might be an issue. I just drilled in to it and it's running two WDC WD1003FBYZ drives in a software mirror, so it seems like it should be capable of better. OF course they set up Server 2012 R2 physical, so who knows what else is messed up.

@mike-davis Might be time to replace the 8 port NetGear Gig switch

I've told them that about 3 times. Each time they turn it down. When I came in they had a 10/100 switch as their core and Server 2003 acting as their firewall. I told them they would have to replace a bunch of stuff just to get up to today's standards. They hemmed and hawed about the price, but I told them to look on the bright side, they haven't spent any money on IT in 20 years...

Well, its failed now... so no choice

I don't know about failed - but they are complaining about speed.
OK - you see this points at NAS, you are maxing out it's capability speed wise. If you want more speed, you must replace that. BUT, be aware, there is a domino effect likely here. You see this points at 8 port switch this is likely to be the next cause of issue because reasons. So simply replacing the NAS likely won't solve your issues, you'll also likely need to replace this switch.
etc, etc, etc,

yep, you get it. They need to hear it a few times.
