What NewsShare NAS Does
Thomson Grass Valley NewsShare NAS is a storage appliance that combines
storage area network (SAN) performance with network attached storage (NAS)
ease-of-use. It consists of server nodes, disk arrays, and a software utility that
supports the storage appliance.
NewsShare NAS supports centralized file sharing in a multi-platform, multi-
vendor environment. It provides up to seven terabytes (assuming you use 146
gigabyte disk drives) of user storage and allows for up to 16 file systems.
NewsShare NAS allows multiple users to simultaneously capture and process
large files among workstations, servers, back-up, and archival systems.
NewsShare NAS has no single point of failure. All active components — NAS
server nodes, RAID controllers, disks, power supplies, and fans — are high-
availability and redundant.
>>> CAUTION: Before replacing any component, back up all array data.
Optionally, NewsShare NAS offers bandwidth management and storage
quotas. These features provide differentiated network storage services based on
the needs of a specific application or client.
Network Architecture
NewsShare NAS server nodes relate to a network in either of these ways:
• Attach NewsShare NAS server nodes to a switch, and then directly attach
each PC, Mac, or Unix workstation to the switch. The connections form the
network. Set up user and group permissions to specify each client’s access
to files on the disk array.
• Attach NewsShare NAS server nodes to an existing network by defining the
mount point and gateway of the server nodes on the network.
File System Management
To increase speed, file system management can be distributed between the
NewsShare NAS server nodes. Specify which server node will manage each file
system. If a server node fails, the surviving server node assumes management
of all file systems. When the failed server node is replaced, it automatically
resumes control of its original file system.
