Netapp FAS3140 CIFS share bit slow

I've e0a & e0b configured as vif1 & e0M for management port, why I'm getting this log warning message & how it is affecting our storage speed.

My write speed from FAS 4130 to FAS3140 CIFS share is 20 MB/s , is it okay ??? I don't want to put my e0M port on different subnet.keeping in e0M in same subnet is an issue ???

Re: Netapp FAS3140 CIFS share bit slow

My write speed from FAS 3140 to FAS3140 CIFS share is 20 MB/s

Re: Netapp FAS3140 CIFS share bit slow

I don't want to put my e0M port on different subnet. 

Why do you need to configure e0M if it is in the same subnet? e0M makes sense only if you have dedicated subnet for administration and do not want to waste 1GbE port for it.

keeping in e0M in same subnet is an issue ??? 

Yes.

Re: Netapp FAS3140 CIFS share bit slow

If I'll disable e0M then you think that this slowness will be solved ??? I mean then data should not get routed through e0M ?

Re: Netapp FAS3140 CIFS share bit slow

You said you see 20MB/s which exceeds 100Mb/s of e0M port. So it is probably won't help in this particular case.

Re: Netapp FAS3140 CIFS share bit slow

what to do to make sure data not get routed through e0M port ? only through vif1 (e0a  +e0b) so that I can maxmm through-put.

sometime I get 40 MB/s while copying data from (windows 2008 r2 disk to netall cifs share),windows 2008 R2 server of clubbed network card (NW1 +NW2 +NW3 +NW4) , total 4 GBps ,

including all 4 gigabit network card on windows 2008 r2 servere will help in enhancing a data speed ?? from server to netapp cifs share ?

Rashid,

Hi there,

NetApp1> priv set diag

Warning: These diagnostic commands are for use by NetApp

         personnel only.

NetApp1*> registry walk options.cifs.tc

options.cifs.tcp_compat_mpx=8

options.cifs.tcp_window_size=17520

Check your tcp window size, if you want better performance for sequential read/write, you need to increase it. Be aware that it will increase needed amount of memory on the machine. Usualy the default is fine for daily workloads, only change it if you have few clients who do large sequential i/o, for example CAD workstations or media editing. Go for 256k if you want to have 1GBit wirespeed.

Regards,

Thomas

Re: Netapp FAS3140 CIFS share bit slow

I've disable my e0M port, now "route -s" is showing all "vif1" but the speed of reading & writing is same as like before in-fact I can say lesser then earlier.what to do now ?? If I'm copying any CIFS shared folder of 4 Gb in the other volume of same filler , writing speed is varying in between 18 MB/s to 30 MB/s.

Is this speed is fair for FAs 3140 ???? what to do now to increase a NAS (read, write) speed.
