Upgrade from Netware Cluster

[kjhurni]

The NSS read ahead block value set on each volume. Netware sets this to a lower value (typically 2 blocks) than gets set as default on OES2L. Setting the value to 16, 32, 64 or 128 (max) can benefit read performance greatly when moving a Netware NSS volume to OES2L (depending on the type of data stored on the volume and storage used). Groupwise volumes typically perform best with small ra block size (2 or 0).

You can see and set the value using nssmu and looking at each volumes properties.

More info can be found in the OES2 SP1 docs : Section 3.7.2, Read Ahead Blocks Setting

Ah okay thanks. Yes, we found out that if you adjust the block read ahead higher than 2, that GroupWise performance goes down the toilet.

But haven't tried setting it higher on a "normal" data volume to be honest.
