Help troubleshooting rndp6000

I am troubleshooting some issues with new old (newly acquired) RNDP 6000 100NAS.

 

This board won't allow me to post my log in zip format.

 

Not sure if disk network or other problem. Trouble with writing to NAS from computer with Acronis true image 2019.

 

p.s. some of the higher temperature operation is when I had the A/C off of minute and should not be an issue.

 

Please advise.

Uses "ac" I think.

 


It's not mine - I don't work for Netgear (neither does anyone else you've been connecting with here).  This is a community forum, you are talking with other users.

 

It is an 802.11ac device (2x2 in the 5 ghz band), so you should be seeing better speeds if you are close to the cradle.  Perhaps confirm that you are connecting to the 5Ghz band.

There is some privacy leakage if you post the full log zip file, so please don't do that. 

 

It's fine to cut/paste a small section though.

Are you seeing any issues reading/writing to a NAS share?  You can use Nastester to test this: http://www.808.dk/?code-csharp-nas-performance.

Re: Help troubleshooting rndp6000

You're entering the wrong thing.  You need to specify a NAS share as the destination, and you need use the UNC format.

 

For instance, if you have a share called Media, enter \\192.168.100.21\Media in the network path field.  Note the direction of the slashes - that matters.

It looks incredibly slow.  Over gigabit ethernet you should be seeing something close to 100 MB/sec.  Is this over wifi?

Re: Help troubleshooting rndp6000

Not undestanding logic of the NAS.

 

The log indicates a command timeout occurred on one drive several days ago.

 

Yet when I did a disk check since then (which took forever) it showed a green light in the software and said it was completed. Apparently no errors (wouldn't it have shown it in the log?

 

So how can there be a timeout when the disk check is 100% ok?

Dropped packets are being dropped by the NAS itself for some reason, not the network.  Occassional drops happen (sometimes related to a lost connection to the NAS).  That stat doesn't look concerning.

 

I do see you have ipv6 enabled on your NAS - you likely are just using ipv4 on your network, so I suggest disabling ipv6 on the NAS.

 

At the botton of the file you shoule see the negotiated ethernet speed for each link.  Can you let us know what speed  and Duplex you are seeting for eth1?  It is normally 1000 MB/s / Full Duplex.

The disk check is running the disk self-test that is built into the drive.  The NAS just reports the results of that diagnostic.  There likely are thresholds built into that test - a couple of errors likely won't result in a fail, but they would show up in the SMART statistics (which are also kept by the drive).

 


@nickel22222 wrote:

Well, obviously you haven't had more command timeouts since then, and the other SMART stats look fine.  I suggested earlier that you keep an eye on the drive, since command timeouts (like reallocated sectors and pending sectors) are an indicator that something might be going wrong.  I wouldn't get too concerned about an isolated command timeouts, but I would be worried if the count starts to increase.

Re: Help troubleshooting rndp6000

Ok, so the NAS is using full duplex gigabit, which can deliver about 100 MB/s throughput.

 

When you ran NAStester (and got ~7 MB/s), how was the PC connected to your home network?

Re: Help troubleshooting rndp6000

The PC was wifi connected to router.

 

Router was ethernet connected to one of LAN ports.

 

If I upgrade from old 1.8 Ghz cpu to 2.6 Ghz, and double to 4 GB ram, will speed improve?

 

Much?

That makes a huge difference.  Are you using 802.11g, 802.11n, or 802.11ac?

You should be seeing ~100 MB/sec over wired ethernet with your current CPU and RAM.  The bottleneck you are seeing now isn't the NAS hardware, it's almost certainly the PC's wifi connection.  You should solve that before considering hardware upgrades for the NAS.

Re: Help troubleshooting rndp6000

That is much better.  The read speeds should also be in the 100 MB/s range, but that might be related to the PC (for instance if antivirus software is running on the PC).  You could see if ethernet flow control is enabled in the PC driver - if it's not, you could try enabling it and see if the read speed increases.

 

Still, it is possible to get much better speeds over wifi.  If you are interested, give us more details on the router model and the PC wifi specs.

Re: Help troubleshooting rndp6000

The wifi uses your Netgear DC112A-100NAS cradle with ATT wifi hotspot.

Uses "ac" I think.

 

Coincidentally LAN connections to this cradle bought on 1-12-18 are erratic at times.

Sorry. yes I'm only on 2.4 ghz due to old devices but that's ok lan is ok.

What is the best I could get for write speed for lan? It seems 115 MB/s is best I can get. I could upgrade ram and cpu maybe.

 

I found flow control enabled for wifi but not in lan device manager settings.

I have 20 tb to backup. anything I can do to speed up within reason is an option.

Gigabit ethernet (1000 Mbits/second) translates to 125 MB per second (for 1000*1000 bytes) and 119 MiB per second (for 1024*1024 bytes).

 

There is overhead (ethernet framing, IP headers, SMB protocol overhead) so you'll never see those values.  So you are at the limit of gigabit ethernet for large file transfers.  RAM/CPU upgrades won't increase your speeds.  The main reason to consider those upgrades is to speed up apps (including Antivirus and File Search in OS-6) on the NAS.  The upgrades won't speed up the file server speeds.

 

If you had current wifi you could certainly gets 25-30 MB/sec speeds over wifi. (translating to wifi speeds in the 200-300 mbits range).

Your PC only has one LAN port, so you are still limited to 1 gigabit for transfers to/from the PC.

 

If you have a lot of simultaneous users you can use Link Aggregation (using both LAN ports) to increase throughput.  But it won't improve the speed of a single client. 

 

About how many wired devices do you think will be accessing your NAS at the same time?
