Fibre Channel RAID storage
IMPORTANT: If your Profile XP Media Platform is part of an Open SAN, refer to
the Open SAN Instruction Manual for information about media storage.
The Profile XP Media Platform supports two storage options, distributed and
centralized.
Distributed Storage
Distributed storage is implemented using RAID storage systems connected directly to
each Profile XP Media Platform. Each Profile XP system accesses media on its own
dedicated storage system. Increased availability to storage is provided by an optional
redundant RAID controller board available for the RAID storage system. If the primary
connection fails, the system automatically switches over and uses the redundant
connection. Media is shared in the distributed storage model by transferring the media
files over an optional video network adapter. With Profile streaming protocol, media
playout can begin before the video network transfer is complete.
Centralized Storage
The Profile XP centralized storage solution, the Open SAN, is implemented using a
Fibre Channel switch fabric to connect all RAID storage chassis and Profile XP Media
Platforms. Centralized storage provides multiple Profile XP Media Platforms
simultaneous access to a common pool of media. As in distributed storage, a redundant
Fibre Channel connection option is available to provide a redundant path to the
centralized storage pool in case the primary path fails.
Fibre Channel and/or Ethernet IP Video Networks
The Profile XP family offers true IP networking of media files over Fibre Channel or
Ethernet.
• Faster than real time transfers (up to 40x) with no generation loss
• Reliable transfers using secure file transfer protocols
• IP networking enables files to be moved between devices or between facilities over
standard public networks.
• Profile network streaming enables “play while transferring”
Fibre Channel Streaming enables the file to be used shortly after the destination Profile
starts receiving it — just like you can do with a traditional video router. This eliminates
the traditional drawback of networking in which the file must finish transferring before
a user has access to edit it or play it out.
