The Graveyard - Products No Longer Supported => D-Link Storage => DNS-343 => Topic started by: AlsRT10 on October 29, 2009, 11:25:29 AM

I own two DNS 343 units with 4 x 1.5 TB drives in each. I have a 1 gig switch that they are both attached to. I just had some problems with HD #1 in one of the units and now that I have swapped it out, I want to reformat this unit. I am transferring 2 gigs of Data to the other unit but the speed is only at 7.7 MB. At this rate it will take me a week to transfer all the data.
Can anyone offer any suggestions?
-
Nah..2GB of data at that rate will take an hour or 2. What is the transfer rate when reading and writing to and from each unit from your PC?
-
To and from the PC is quite fast. I just purchased a new computer with windows 7 and the fastest Intel i7 processor with 12 gig of ram..everything on this computer is fast. Just the transfer rate betwen the two units is very slow. It is now transferring at 8.0 MB. I even tried to enable jumbo frames, but to no improvement.
-
What is the transfer rate and is it the same to and from on both DNS-343 units?
-
The current transfer rate is 5.82 mb. I am only transferring one way right now, because I'm backing up the 1st NAS unit. According to the transfer rate, I should be finished in 20 hours!!
-
Strange I have transfered 1TB at about 7Mbps in about 8 or 9 hours. Oh I see you have the transfer going now so you cannot tell me the speed from your PC to each NAS right now.
-
I'm going to stop the transfer and push the files to my PC then back to the other Nas unit. I'll let you know.
-
I transferred 2 movie files from each of the two units back to my PC. They both transfer the files at approx. 30 mb
-
So transferring from NAS to NAS you get 7.7 Mbps and from PC to the same NAS you get 30Mbps??
-
From the NAS units to the PC I got 30 Mbps, from the PC to the NAS I'm getting (right now) 6.01 Mbps.
-
So you are able to read from the NAS at 30Mbps and write to it at 6.01 Mbps..correct? Just want to verify I have to correct information.
-
That's correct for both units.
-
What devices does you network consist of?
-
A D-Link DGS1008D switch, Speed Stream Modum.
My computer has an Intel i7 975 at 3.33 GHz, with 12 GB of Ram,
Marvell Yukon PCI-E Gigabit Ethernet Controller
Hard wired

Have you tried setting a static IP address to the PC and DNS-343 and connecting them directly?
-
I currently have static addresses for both NAS units and my computer. Even if I bring the units to the computer and hook them up directly, this would then defeat the purpose of having them on a network. My NAS units feed my home theater systems throughout my home. I have a very complex system, and having them hooked up to the computer will prevent access. What is this designed read/write rate? Can this be improved through software changes or is this a hardware issue?

Yes it would defeat the purpose of having them on a network however it would help diagnose where the problem might be in order to resolve your issue.

Old trick - If slow between computer and NAS, go your network adpater (control panel/device manger/network adapters/properties/advance/speed & duplex) if set at auto-negotation change to 100 or 1000 Mbps full duplex. My transfer speed increased a lot.
-
Thanks for the tip, however, it only increased from 5.8 Mbps to 8.8 Mbps. I was looking for something much faster then this. I can only hope that D-Link is looking into this issue.
-
8.8 Mbps? you must mean MB/s instead, surely? On my setup I get 28 Mbps or 30 Mbps (16 MB/s or 18 MB/s) approx.. But i don't use any RAID setup and i'm using a Gigibit network.

What would it be you would like us to be looking into? Did you try removing the switch and connect the DNS-343 directly to your PC using a static IP address and locking the the NIC and DNS-343 to 1000?
-
After trying "dichamw" old trick the speed increased a little, but then both DNS-343 units crashed. "System Halting" message was on for so long that I pulled the plugs. Then it took several tries before I could get it to reboot completely. I have not tried the direct approach, because frankly, this would not be a solution that I can live with. I purchased these units to perform on a network capable of sharing movies across two media servers, without have the computers on. However, have you tried this solution, and if so what read/write speeds did you get? Is the RAID setup the problem here? "skrupka" is getting 28 to 30 Mbps. The NIC is set to 1000.
