                                Notes and Tuning

<> Disks were bound in 5 disk RAID-0 groups.
<> Each RAID group contained 1 of the File Systems under test.
<> An additional 9 disk RAID-5 group with 1 hot spare disk was accessible by both disk controllers, but not used in the test. The storage backup for the NVRAM also resides on these 9 disks in a special area.
<> The IP4700 Storage Processors are referred to as SPs (SPA & SPB).
<> Each SP controls half of the RAID Groups/filesystems (SPA: A1-A9, SPB: B1-B9). However, each SP can see the RAID Groups owned by its peer SP in order to facilitate failover. Failover is automatic should an SP fail.
<> Each SP has 1 Gb network port. Both network ports reside on the same subnet. This facilitates network port failover. Failover is automatic should a network port or SP fail.
<> Checksum offloading was enabled on the Alteon ACEnic adapters.
