1.2.1 Lustre 1. 4 .11
SFS 2.3 now uses Lustre 1.4.11, plus patches for numerous bugs fixed in Lustre 1.4.12 and later.
1.2. 2 NFS re ex p o r t o n Li nux 2. 6
SFS 2.3 now supports NFS reexport on Linux 2.6.
1.2.3 O F E D 1.2 o n ser vers
When configured to use OFED, SFS 2.3 runs OFED 1.2 on servers (InfiniBand OpenFabrics Enterprise
Distribution version 1.2).
1.2.4 OFED 1.2, 1. 2.5 , 1.3 o n clie n t s
OFED 1.2 is the default OFED InfiniBand stack for clients. OFED 1.2.5 and 1.3 are also included in the client
enabler kit. Using the appropriate build options, one can choose either of these two stacks.
1.2.5 Support for multiple OFED InfiniBand interfaces
SFS 2.3 supports multiple IB interfaces when running OFED.
• On the SFS client side, this allows to increase the per node aggregate bandwidth. The IB traffic is
distributed over the available IB interfaces on a per OSS target base.
• On the SFS server side, there is no real performance benefit in using a second interface since the
limiting factor is the storage bandwidth. But adding IB interfaces allows connecting of a single SFS
system to multiple IB fabrics.
In both cases, it is required to configure multiples LNETs. Please refer to the SFS System User Guide section
7.9a for configuring multiple IB interfaces.
