High CPU Load on SP A, suggestions?
Hi,
We are running an NS-120 with two Datamovers (one in standby and one primary). We want to create more CIFS servers but are concerned there is already a high CPU load on the first datamover (around 95%).
So two questions, how can I investigate what is causing the high load (or should we conclude it is normal for our size/setup)?
And, what are the potential problems, benifits of using the standby datamover as a 2nd primary and presuambly splitting the load across the two processors?
Thanks in advance,

This is more of Celerra question and maybe the moderators can move this to that forum as you might get a better answer over there. Maybe you should change the title of this thread to "High CPU Load on DataMover1"
I dont know alot about the celerra product and i am not sure if you can configure your standby DM to be a 2nd primary. If it can be done you would have to keep in mind that if you had a DM failure, you wouldnt have any failover and could be stuck with an outage untill that DM is fixed or replaced.

you can configure a celerra with no standby datamovers but as it was mentioned, you will then have no failover for either production datamover. the server_standby is the cli command that is used to create datamover types. nas_server -l will list you the datamovers and their policy type. type 1 is production, type 4 is standby.
Probably better to have emc dial-in and investigate the performance load.

you want to investigate what clients/process are causing high utilization, look into server_stat command
