Bandwidth variation—number of OST services and number of client nodes
B–9
B.6 Bandwidth variation—number of OST services and number of
client nodes
The graph in Figure B-5 shows how the aggregate file system bandwidth varies as the number of client nodes
is increased and the file stripe count used by the client nodes also increases.
Figure B-5
Bandwidth variation—increasing numbers of client nodes of and OST services
Each client node writes its own file. These results are based on the following configuration:
•
Up to four Object Storage Servers
•
Four SFS20 arrays attached to each Object Storage Server
•
Each array populated with twelve 250GB disks and configured as one 2TB LUN with ADG (RAID6)
redundancy
•
Voltaire InfiniBand interconnect
All results are based on tests using new, empty file systems with default MDS and OST mount options and
without quotas enabled.
