PowerProtect DD System Administration

Backup administrators have observed slow backups in the AIX environment.

To resolve the issue, what should large_send be set to for each NIC, and what should the NFS option be set to?

  • A no and nfs_rfc1323=0
  • B yes and nfs_rfc1323=0
  • C no and nfs_rfc1323=1
  • D yes and nfs_rfc1323=1
Explanation

For this AIX NFS backup workload, disable large_send on each NIC and enable nfs_rfc1323. The nfs_rfc1323=1 setting permits TCP window negotiation above 65,535 bytes for NFS, supporting higher-throughput NFS transfers with large RPC sizes.
