HP StorageWorks Scalable File Share - Manual (Page 73)

The OSTs were populated with 146 GB SAS drives. Stripe placement was controlled by default
operation of the HP SFS file system software. Specific control of striping can affect performance.
Due to variability in configuration, hardware, and software versions, it is not valid to directly
compare the results indicated in this section with those indicated in other sections.
A.8.1 Benchmark Platform
The performance data is based on MSA2212 controllers for the HP SFS component. The
configuration described in Section A.1 was modified only in terms of the link connecting the
clients to the HP SFS servers. In the modified configuration, depicted in
Figure A-14 , a set of
eight blades were connected to each of two blade switches in the blade enclosure. Each blade
switch was then connected through a four-line trunked set of 10 GigE lines to a ProLiant 8212zl
switch. Each of four OSSs, the MGS, the MDS and the head node of the client cluster was connected
to the 8212zl through its own 10 GigE connection.
Figure A-14 10 GigE Connection
NOTE: Please refer to the documentation for the network switches utilized in your specific 10
GigE interconnect. The design of the network connections should account for the capabilities
and options available for the utilized switches. Carefully study the mechanism responsible for
routing packets through the links comprising any involved trunk.
Network buffers maintained in each of the involved network switches can affect overall
performance in a manner that is difficult to predict. For these tests, flow control was enabled
throughout the 10 GigE network components to reduce the effects of buffer overruns. System
