240 TB, Drawer 2 (Bottom) — Initial Media Drive Slot Locations and RAID Groups
ISIS 2000-120 Media Drive Configuration
The ISIS 2000-120 has 42 media drives with two drives reserved as hot spares. The drives are
configured in the Avid ISIS-120 Engine as four RAID 6 groups (10 drives in each group). The
hot spares are initially created in the bottom drawer and are automatically used whenever a
RAID set detects a degraded drive. This allows for continued access to your workspace data with
no data loss during the failure and repair.
c
The spare drives are created in the bottom drawer when the RAID groups are initially
configured. Once a drive group has used a spare drive and a new spare is established, the
original configuration no longer applies.
c
When replacing a failed media drive, you must install the replacement drive in the slot
where you removed the failed drive. Do not install replacement drives in the slots identified
as “Not Used” in the following illustrations.
