Media Storage Subsystem
The Media Storage Subsystem includes the following components:
Fibre Channel Disk Board
This is a dual port Fibre Channel Disk board for connecting the Profile XP system to
the external Fibre Channel RAID storage system. Both ports use a copper Gigabit
Link Module (GLM) for copper Fibre Channel cables. The system normally operates
with only Port A connected to the PFC500 system. When the PFC 500 is ordered with
the optional second controller board, Port B can be connected to provide a redundant
path to the disks, or for increased disk I/O bandwidth.
PFC500 Fibre Channel RAID Chassis
The PFC500 high performance RAID storage system provides the Profile XP a low
profile, compact storage system with either 18 GB or 36 GB fibre channel drives. The
PFC500 is a 3.5 RU 10 drive Fibre Channel disk array with RAID drives, hot spares,
dual power supplies (optional), redundant controllers (optional) and spare fans – all
hot swappable.
The PFC500 comes with either 18 GB (PFC518) or 36 GB drives (PFC536).
Expansion can be done with the PFC518E/536E expansion system 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 total drives). The PFC500 offers optional
redundant RAID controllers. If one fails, the system will automatically switch over to
the second controller within a few seconds.
