PFC500 product description
The PFC500 is a 3.5 RU 10 drive Fibre Channel disk array with RAID drives, hot
spare drives, dual power supplies (optional), redundant controllers (optional) and
spare fans – all hot swappable. The PFC500 comes with either 18 GB (PFC518),
36 GB (PFC536), or 73 GB drives (PFC573).
PFC500 expansion is available using the PFC500E Expansion Chassis which houses
5 or 10 drives, but does not need a RAID controller. The PFC500’s RAID controller
will control up to 2 expansion frames (30 drives total). All PFC 500 chassis must
contain the same size disk modules to make full use of the storage capacity.
NOTE: Grass Valley Group does not support mixing disk drives of differing
capacities in any RAID chassis connected to a Profile XP media platform. All disk
drives in any RAID chassis connected to a Profile XP media platform must be of the
same capacity. For example, if a PFC 500 and a PFC 500E are connected to a
Profile XP system, all the disk drives in both the PFC500 and the PFC 500E must
be of the same capacity.
The PFC500 offers optional redundant RAID controllers for automatic failover.
Failover can occur when the primary RAID Controller, Fibre Channel Port of the
Profile XP, or Fibre Channel cable fails. When failover occurs, the system continues
to run with minimal interruption.
For additional information on the PFC 500 Fibre Channel RAID chassis and the
PFC500E Expansion chassis, refer to the PFC500 Instruction Manual.
Storage capacity estimates
The storage capacity is determined by the number and size of disk drives in system,
and the video data rate selected to record video. The PFC500 Fibre Channel RAID
storage system can be configured with five to thirty disk drives, including the
PFC500E Expansion chassis.
You can refer the following tables for storage capacity estimates based on the number
of disk drives installed and the video data rate. The estimates in these tables are based
on use of four audio channels and one time code channel per video channel using the
525 video format.
