ReadyNAS 4220 Transfer speed drop
Dear all I have a problem during the transform from the NAS storage , the speed start at 3 Gbps and decrease to 1 Gbps some time to Zero and then back to 1 Gbps , where is the problem might be ? ...
Dear Stephen
the firmware is 6.9.3 , we used iSCS protocol and the problem with both direction
the other device is HP DL380 G7 server and connected directly to the NAS through 10G SFP.
Is this a large file transfer test, or are you copying a lot of small files? If the latter, you might want to try a large file transfer.
Are snapshots enabled? Normally you'd have snapshots turned off on the NAS LUN, since leaving them on will fragment the LUN (and use a lot of snapshot space).
Also, is this a new problem?
Yes , the problem happended with large file also with alot of small files , the snapshot disabled .
in fact i'm new to NAS world and i'm in a place contain server and two NAS storage that connected to the server
with iSCS via fiber link NIC
- is this the best way to connect my storage ?

That should be a good way. My own system (an RN526X) is connected via a 10GbaseT.
It's worth downloading the log zip file from the NAS, and looking at disk_info.log to confirm the disk health, and also looking in system.log and kernel.log for any iSCSI related errors. Network_settings.log should give you some stats on the fiber link.
If this is a new installation, you should have 90 days of phone support - so you could contact Netgear via my.netgear.com.
I'll duble check all logs , another qustion please why the admin page show the storage was full while there was afree space on it .
