| High Performance
The NS-IS 's high performance comes from the 64-bit
Power PC CPU and proprietary ASIC. For higher efficiency
and more throughput than most small to medium sized
servers or workstations, the bandwidth of the 64-bit
bus runs at 66 MHz between the SDRAM and the CPU. Data
is distributed through a high speed 64-bit path at a
burst rate of 533MB/second. The system's overall performance
reaches up to 109MB/second and 5480 IO/second nearly
equaling the combined performance of all the drives.
The dual independent PCI bus design eliminates bandwidth
bottlenecks for IO traffic. The balanced bus loading
and highly scalable design make the NS-IS an optimal
RAID solution for a wide range of SCSI based PC's, single
user workstations, NT, Linux and Unix based servers.
High Data Availability
The system provides RAID levels 0, 1 (0+1), 3 and 5.
RAID configurations can be managed either through the
LCD control panel or by the system-embedded configuration
utilities.
Its high data availability and protection derives from
the following capabilities: automatic drive failure
detection, automatic failed drive rebuilding, hot spare
and background rebuild, disk hot swap, and online background
rebuilding.
Redundant Power Supplies
Two Hot-Swappable redundant Power Supplies provide zero
down time and fault tolerant power. With two Power Supplies
installed, both will share the current power needs of
the whole system. If one should fail, an alarmwill
sound and the remaining power supply will take over
the full load until the faulty unit is replaced. The
Hot-Swap feature ensures that the system remains operational
while replacement is taking place.
Redundant Cooling Fans
Two cooling fans are integrated for redundancy. Failures
are displayed by the RAIDGuide manager software.
The system's ventilation is from front to back. Specially
designed airflow passages dissipate heat from the hard
disks and the controller. Power-supply modules are equipped
with their own independent cooling fans.
Setup and Status Monitoring
The system will automatically initialize based on the
number of disk drives installed at start up. Manual
configuration and monitoring can be done through the
LCD control panel. The firmware contains an embedded
management program that can be accessed using a terminal
connected to the RS-232C port.
RAIDGuide Manager
RAIDGuide, an advanced and user-friendly GUI management
program is also available to communicate between the
host and the array through a proprietary in-band SCSI
protocol. RAIDGuide is a complete management interface
to the disk array. Users may view the status of all
the connected drives, enclosure components, and controller
board at a glance. The GUI design makes maintenance
of the enclosure a simple matter of point and click.
