About this Manual
Welcome
Congratulations on the purchase of your new NexStor® 4700S Series RAID
Storage System from nStor Corporation. This NexStor series is a low cost-high
capacity, fault-tolerant advanced serial technology architecture RAID storage
system. It’s unique 2U design is optimized to fit in the compact space of today’s
data centers rack environments and fit comfortably as a deskside tower system.
The storage enclosure supports up to twelve hot pluggable 1-inch high Serial
Advanced Technology Architecture (SATA) disk drives in a 2U (3.47-inch) form
factor. Component redundancy is found in the hot pluggable cooling fan module
which contains dual in-line fans and will continue to provide adequate cooling
should one fan fail. An N+1 power system is available by adding the optional
second independent power supply. Each power supply is a hot swappable
component that continues to operate without interruption to normal service with
the loss of one power supply.
Host connectivity is provided through dual independent 320 MB per second SCSI
ports (VHD/CI connectors). Likewise, scalable expansion is made available through
dual independent Ultra320 ports. RAID functionality is provided through the single
onboard nStor designed SCSI-SATA RAID Controller.
The design of the storage system implements Serial ATA II technology which
provides a highly reliable system architecture that supports command queuing and
hot swappable SATA disk drives. Serial ATA brings efficient I/O performance and
boosts storage capacity over conventional RAID storage systems.
