Fibre-Fibre RAID
Controllers
Overview
The NS-RC 2510FS is what you need for the
2Gb/s Fibre-Fibre RAID storage applications. It is designed
for achieving the highest level of data availability,
performance, and storage sharing. Its modular design minimizes
the time for maintenance and adds scalability in the SAN
environments where the demands for more capacity and higher
performance can never cease. It is a durable subsystem
that can be easily configured and operated with the cross-platform
GUI. It comes with complete component redundancy and FC
support, including that for dual-loops and multi-host
configurations.
Models
Four models in the series stand for the various customizations
using single or dual controllers. For the applications
that aim at performance rather than redundancy, single
or dual-single controllers may be sufficient. For the
applications that require 24-7 availability, the "dual-redundant"
models have all the necessary functionality to ensure
the system will survive catastrophic events.
Feature Highlights
2Gbit Fibre-to-Fibre; FC-AL, point-to-point, and switched
fabric
4 or 6 redundant channels in the dual-active redundant
mode up to 12 FC channels in the dual-single mode
Modular and hot-swappable design of all critical components
Designed for No Single Point of Failure
Full-featured active-active redundancy with synchronized
cache
LUN Filtering - RAID-based and centralized access management
in SAN
Battery-protected cache memory; architecturally supports
up to 1GB
Chassis: 1U or 44mm (H), x 427mm (W), x 537.1mm (including
front ears -D) and 19" rack mountable
High Performance
The controller incorporates Infortrend's proprietary
dual-ASIC and separate-bus architecture with a state-of-the-art,
64-bit PowerPC processor. The controllers can achieve
an exceptional performance transferring data at a maximum
read bandwidth of 700MB/s (dual-single), RAID 0 write
bandwidth of 640MB/s and RAID 5 write bandwidth up to
350MB/s.
Flexibility
Pre-set schemes are available in firmware for an optimum
setup of host and drive channels and system resources.
Logical configurations of drives can be assigned to
different controllers/multi-IDs with different LUN filtering
entries. This can be done for both load sharing and
access management in the shared-storage environments.
The controller head supports a complete range of RAID
levels 0, 1 (0+1), 3, 5, 10, 30, and 50 storage. It
is capable of advanced data protection and the complete
system redundancy. All critical components are hot-swappable,
including RAID controllers, power, fan, and even the
I/O modules. In the active-active configuration, data
cached on one controller has an exact replica on another
controller through the communications over drive loops
or a dedicated data path. Controller failover and failback
are totally transparent to host computers.
Data availability is guaranteed by a long list of sophisticated
firmware functions: Dedicated/global hot-spares, battery-protected
disk cache, configurable reaction schemes against SMART
detected errors, remote and real-time array monitoring,
and more.
SAN Fratures
The controller supports LUN Filtering, a centralized
access management capability. Up to 1024 filtering entries
are supported and multiple entries can be mapped to
each logical unit. Various functions; like host port
auto-identification, filter type selection, entry naming,
and access mode configuration; make shared storage an
easier task.
Manageability
The Java-based RAIDWatch GUI manager provides easy-to-use
interfaces, is rich in configuration options, and allows
users to remotely manage their storage system over a
network. Its submodules, Event Monitor and NPC, provide
system managers the freedom of real-time monitoring
via a variety of notification methods.
