Oracle HSM - Slow Data Transfer Performance Over NFS To SAM-FS Filesystem (Doc ID 2062246.1)

Last updated on OCTOBER 25, 2016

Applies to:

Oracle Hierarchical Storage Manager (HSM) and StorageTek QFS Software - Version 5.3 and later
Information in this document applies to any platform.

Symptoms

When mounting a SAMFS filesystem on a client system (Linux or Solaris) via NFS, the write performance is extremely poor.

Below are the tests which can be run in order to isolate the issue:

read/write over NFS to local disk on Solaris = OK
read/write over NFS to ZFS appliance (ZS3-2) shared through Solaris = OK
read over NFS from SamFS = OK
write over NFS to SamFS = NOT OK
