Performance figures B–6
B.4 SFS20 RAID5 and ADG performance
The graphs in Figure B-2 and Figure B-3 show the streaming write and read performance for HP SFS
configurations using ADG (RAID6) redundancy. The graphs also compare the measurements for ADG
redundancy with the measurements for RAID5 redundancy.
Figure B-2 RAID5 and ADG write bandwidth
Figure B-3 RAID5 and ADG read bandwidth
These results are based on the following configuration:
• ADG configuration
• Four SFS20 arrays attached to each Object Storage Server
