Hi all;
ONTAP 8.0/8.1 mix.
Looking for best practices on optimizing seqential read (throughput) access via CIFS from WAN locations (up to 80ms latency).
Here's what I have so far:
- Enable SMB 2.0 on filers. - Increase CIFS TCP Window size to ~2MB (default seems to be 17520 bytes)? - Ensure clients at remote sites have either large TCP window sizes set or allow for TCP window scaling (clients are OSX).
Obviously some sort of WAN acceleration appliance at the remote site could help as well.
Anything I'm missing?
