D-Link DGS-1016D and ReadyNAS Duo
Anyone have any experience with the D-Link DGS-1016D? It is an unmanaged switch which I picked up for $130'ish at OfficeDepot. Just getting ready to start tweaking our small office network and didn't see this 10/100/1Gb switch listed. I currently have it installed, but have not enacted jumbo frames. Cabling is all CAT 5e and the two primary PC have 1Gb NICs which show to be operating at that speed as well (via Windows Control Panel/networking). We have had the ReadyNAS Duo installed for approximately 3 weeks. We bought the unpopulated unit and added two 1Tb Seagate ST31000528AS for RAID level 1 (or X-RAID).
Only "weirdness" we are seeing is that the connection to the NAS gets dropped during periods of inactivity sometimes but comes back when the drive mapping is double clicked. OS wise, we have XP and Win 7 (32bit XP mode) - both exhibit this. I have checked the NAS settings and the idle drive parameter has not been activated.

- I don't have any experience with the D-Link rack mount switches, but I have a DGS-2205 desktop switch (apparently now discontinued) that I had in service with my NV+ and it worked well with no problems, until I added my first x-86 class ReadyNAS (NVX Pioneer) and it was fine as long as I was copying file onto the NAS, but disastrously slow transfer when copying files off (less than 1KB/s). Netgear technical support was convinced that I had a bad chassis, and was preparing to issue me an RMA. At the suggestion of this forum, I tried a direct connection and suddenly all the problems disappeared. Needless to say the DGS-2205 is now in my closet, replaced by a Netgear GS-108.
You might want to take one of the client stations that is experiencing this problem and connect the Duo directly to it to see if it could be the switch. - Thanks for the quick follow up. I may try that. I presume I need a direct connect, ethernet crossover cable?
- No. The desktop ReadyNAS line at least, is auto sensing and will adapt. I use the exact same Cat6 cable used between my NAS and the switch, I just redirect it to the desktop instead. Of course if your wiring is in the wall, you would have to carry the Duo to a workstation and use another cable, but with the Duo any good ethernet cable would be good. (With the x-86 you need Cat5e or better).
Also, since the symptom is on multiple workstations, it's unlikely to be the cable. - I've turn the NTP Option "clock sync" off, first night no drop offs but I also playing with the IOMeter tests and ended up running it all night.
My baseline results with our RadyNAS Duo are 22.05Mb/s Write and 34.6Mb/s Read on this 10/100/1Gb switch. These are factory default settings, no jumbo frames and index journaling is still on. It is on a shared UPS, but I have a bought a dedicated APC unit with USB to allow for enabling these advanced options. - You are wrong about the switch. It is not a 10/100, but a 10/100/1000 rated switch according to the D-Link site. Those speeds are typical to a little better than typical for a Sparc Based NAS on a gigabit rated network. My NV+ is typically around 25 MB/s. If you were on a 10/100, it would be a theoretical max of 12 MB/s (100/8).
- Thanks. I've turned on Jumbo frames and disabled journaling and saw a decrease in speed: 14.1MB/s write and 25.7MB/s Read.
- Jumbo frames off and up to: 16.3MB/s write and 26.3MB/s read. May try to re-enable journaling.
- I tested the network after hours with the NAS rolled back to factory defaults; back up to 23MB/s Write and 34MB/s Reads. Me thinks I'll leave well enough alone.
- I don't think you'll get much better with a sparc based NAS. Your read speeds are greater than I can get with my NV+, but not by a whole lot. My test file is a 3GB mp4 file so that may have some effect.

Added the NoSMBDissconnect driver/option and this has gone away.
