LGX-4TBR-N
4 terabyte RAID hard disc storage device
for use with TOTAL SHARE option
Expanded Media Storage
The UltraNEXUS TOTAL SHARE option dramatically increases your digital media
storage capacity. TOTAL SHARE allows you to configure a private, dedicated
digital media storage network using approved network attached storage (NAS)
devices. The expanded private storage network is exclusively for local digital
media storage and is isolated from the primary gigabit Ethernet port used for
system control. Up to 12 terabytes of expanded storage may be configured
in addition to the standard USB storage for an overall system capacity of 16
terabytes!
Increased Channel Capacity
Increase your system's channel capacity by attaching two UltraNEXUS/NEXUS
video servers to the TOTAL SHARE network. The UltraNEXUS/NEXUS units
share all NAS devices on the TOTAL SHARE network, creating a modular video
server system.
Visit www.leightronix.com/total_share.php for more details on expanded storage
and channel capacity.

on MPEG-2 encoding with full D1 resolution (720x480) video and 256Kb/sec
audio bit rate. The UltraNEXUS also supports variable bit rate (VBR) encoding,
offering the potential for even more storage time.
