System Node
The DXi8500 System Node contains thirteen 146GB SAS hard drives (1TB
and 2TB systems) or fifteen 300GB SAS hard drives (3TB systems) and
supports RAID 10 or RAID 1 configurations (depending on the type of
data being stored on the drives—boot software or Metadata storage)
with one hot spare. All drives connect to the system board through the
SAS backplane board. Hard drives are supplied in hot-swappable drive
carriers that fit in the hard-drive bays.
The hard drives, which are located on the front of the System Node, are
used to store either the boot software and StorNext File System (SNFS)
journals or the SNFS Metadata (see
Figure 7
and
Figure 8
).

• The first drive in the System Node (Drive 0) is the global hot spare.
