DXi6902 Array and Expansion Modules
The DXi6902 Array modules (RBODs) and Expansion modules (EBODs)
are used to provide additional capacity (backup data storage) for the
DXi6902 system. Each Array or Expansion module contains 12 drive
carriers and provides 34 TB of licensable storage.
The DXi6902 includes 1 or 2 Array modules (RBODs). Array modules
connect to the Node and contain dual RAID controllers, which provide
storage management logic. The DXi6902 includes 0 to 13 Expansion
modules (EBODs), which connect in a chain to the Array modules, and
which provide additional storage capacity only.
Note: Storage capacity is licensed in 17 TB increments.
The DXi6902 Array and Expansion modules have a series of LED
indicators and buttons located on the front and back of each
component:
• Array and Expansion Module Front Panel Features and Indicators
• Array and Expansion Module Hard Drive Carrier Indicators
