HP StorageWorks Scalable File Share - Manual (Page 340)

Performance figures B–12
Figure B-9 9000 MTU average write MB/sec
Figure B-10 9000 MTU average read MB/sec
These results are based on the following configuration:
• One Object Storage Server
• Four SFS20 arrays attached to each Object Storage Server to ensure that the storage bandwidth
would not artificially reduce the network throughput figures.
• Various interconnect combinations with one and two active links.
Streaming read or write accesses can be increased by a factor of two when an additional link is added to
the server. In this case, each client node wrote (or read) a separate 4GB file striped across four SFS20
arrays.
The graphs also show that client bandwidth can be increased by the addition of a second link.
It is not currently possible to use an MTU greater than 1500 for bonded Gigabit Ethernet links.
