plus redundant power and fans.
Up to 12 Engines are supported in the ISIS | 5500 network:
With 2 TB media drives, the system delivers 384 TB of shared storage

The first ISIS Engine provides System Director and Management Console functionality in
addition to media storage. The Avid ISIS | 5500 network can support up to 90 Ethernet connected

Avid ISIS ensures media protection and availability using the following techniques:
Mirrored system drives are used for system operation and System Director metadata storage.
A failed system drive can be replaced without interrupting the operation of the Avid ISIS.
The 16 media storage drives are configured into three RAID 5 groups with one drive
reserved as a global hot spare. If any of the RAID drives fail, the Avid ISIS automatically
uses the spare drive to rebuild the RAID group. The failed drive can be removed and
replaced with a new drive without interrupting the operation of the Avid ISIS.
