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.
