Level 3 RAID components
Level 3 RAID components
The Level 3 RAID components are:
• The chassis with passive midplane board
• One or two RAID controllers (K2 Level 3R) or two expansion adapters
• As many as fifteen Fibre Channel disk drives per chassis
• Two RAID chassis power supplies (K2 Level 3) or expansion chassis power
supplies
Any unoccupied slot (RAID controller or disk module) has a filler module to maintain
air flow and compliance with electromagnetic interference (EMI) standards.
The RAID controllers, expansion adapters, disk drives and power supplies are
hot-swappable field replaceable units (FRUs), which means you can add or replace
them while the Level 3 RAID is powered up.
IMPORTANT: You must not hot swap operational RAID controllers or disk drives
without first disabling the target component using the Grass Valley Storage Utility.
An optional second RAID controller module in the Level 3 RAID, allows for
continued access to the Level 3 RAID if the primary RAID controller fails. Refer to
the K2 Storage System Instruction Manual for detailed connection and configuration
instructions.
The following figure shows the RAID Storage Chassis components. Details on each
component follow the figure.
