38 CONFIGURING THE HP EFS WAN ACCELERATOR

Enabling the

NFS-

Application

Streamlining

You enable NFS-application streamlining in the Optimization Service - Protocol: NFS

page. NFS-application streamlining provides latency optimization improvements for

NFS operations primarily by prefetching data, storing it on the client HP EFS WAN

Accelerator for a short amount of time, and using it to respond to client requests.

You enable NFS-application streamlining where NFS performance over the WAN is

impacted by a high latency environment.

NFS file system objects have owners and permissions and NFS-application

streamlining conforms to the file system permissions model by enforcing file server

and volume policies. You must ensure that the policy is set correctly to Read-Only or

Global Read-Write as appropriate. Setting the policy to Read-Only on a non-read-only

file system results in Read-Only file system (ROFS) errors.

To enable the NFS

optimizer

1. Click the Setup tab to expand the Optimization Service menu.

1. Click Protocol: NFS to display the Optimization Service - Protocol: NFS page.
