LAN speed
-
I don't know the cisco commands, but I'm assuming you can run a command on the switch to see what speed each port is currently set to run at.
-
Also, what RAID level did you pick? If you picked RAID 5 for example, the device could be doing some sort of setup across the drives that may have to finish before you'll see full performance (this is only a guess).
-
@Dashrender it is a RAID 10, array of 4 HD, 3TB each
this is what makes me disappointed because i'm supposed to get better performance, i mean the RAID10 include RAID 0 which increase the speed of R/W, but unfortunately i didn't obtain even the normal speed -
You can check by looking at the LEDs on the front of the switch port. If one is a solid green it is 1Gb/s if it is yellow then it is 100Mb/s.

it is blue Sir, all 4 are blue
-
Did the NAS come with the Drives, or did you purchase them separately?
Do you know what model hard drives is in the NAS?

On the Cisco Switch? Where the cables plug in? Not the other side (assuming there are lights on the other side).
-
Oh man... it looks like Solid blue indicates the port is running at 10Mb/s (If I'm reading the right documentation) if the duplex LED is also blue then you are running at half duplex.

Hopefully that's not right - since he did indicate that he checked on the server NIC status and it told him he was running at 1 Gb.

NAS WD my cloud EX4 12 TB
The documentation here PDF jump to Page 125 has all of the network information for this system.
So it's easily confirm-able if this unit is set for Half or Full Duplex, as well as the speed of the NAS NIC.

yeah i'm talking about the NAS LEDs not the switch LEDs,
the switch LEDs are green -

Can you go into the network page on the NAS, and screen shot that for us?
I have a feeling the speed within the NAS is set to Auto. Which if it is, is likely causing the performance of the NIC to be slow. So either there is something wrong with the configuration on your Switch. Or the NAS.
-
the front side of the NAS itself has LED above each HD, i thought you are talking about them

Those LED are status indicators of the drives them selves, not the performance of the NIC connected to the back of the NAS.

yes you are right, the link speed is set to auto, should i change it to 1000 ??

Yes, but be warned.
If for some reason that the speed isn't supported on your switch, you'll likely be unable to manage the NAS without performing a factory reset on it.
It should be supported, but it sounds as if the NAS is connected at 100MB.
Confirm that you can connect to the NAS directly via direct Ethernet before making the switch to 1000MB/s in case you must change it back.
-
thank you for your advice, but the cisco switch (catalyst 3560) is 1 Gb/s, this is for sure
-
It's been a while since I've seen auto not work as advertised,
So I ask - is it still best practice to manually set the switch and server manually to the desired speed and duplex?
