File Manager and Backup File Manager

File Manager and Backup File Manager
The File Manager is a rack-mount, dual-processor computer running the
Windows 2000 Workstation operating system.
The File Manager maintains the storage location information for the drive set
by caching a complete set of file system metadata in memory. To ensure the
integrity of this metadata, the File Manager uses error-correcting code (ECC)
memory and periodically writes three complete copies of the metadata to
multiple drives in the storage subsystem. The metadata is also written to the
drive set when the File Manager service is shut down.
In addition to the active File Manager, another computer can be set up as a
backup File Manager to provide system redundancy. The backup File
Manager automatically picks up for the active File Manager, within
1to2minutes, if it goes offline for any reason.
Fibre Channel Adapter Boards
Each File Manager, PortServer and MediaNetwork Fibre Channel client
requires a Fibre Channel adapter board to connect to the Fibre Channel
network.
The File Manager’s Fibre Channel adapter board allows it to connect to the
storage subsystem, access the Fibre Channel drives, and manage and maintain
the file system on the drives through the MEDIASwitch 16-4G.
The client’s adapter board allows them to access the storage subsystem and to
send messages to the File Manager through the MEDIASwitch 16-4G.
MEDIASwitch 16-4G
The shipping 4-Gb MEDIASwitch 16-4G contains 16 ports. The
MediaNetwork workgroup can have 1 or 2 switches. The switch allows you to
connect the File Manager, several PortServer or PortServer Pro systems,
several MediaNetwork Fibre Channel clients, and up to six MEDIArray ZX
drive enclosures (either individually or in pairs of daisy-chained enclosures)
together.
