To enable Hybrid Columnar Compression (HCC) on Direct NFS Client, perform the following steps:

1. Ensure that SNMP is enabled on the ZFS storage server. For example:

   C:\>snmpget -v1 -c public server_name .1.3.6.1.4.1.42.2.225.1.4.2.0
   SNMPv2-SMI::enterprises.42.2.225.1.4.2.0 = STRING: "Sun Storage 7410"
   

2. If SNMP is enabled on an interface other than the NFS server, then configure oranfstab using the management parameter.

3. If SNMP is configured using a community string other than public, then configure the oranfstab file using the community parameter.

4. Ensure that Wsnmp32.dll and snmpapi.dll are installed by checking if snmpget is available.
