¡´Channel connection. The performance of the bus
is achieved by combination of four SAS channels with each
supporting
¡´3Gbps full duplex speed. Together with a
high-speed SAS HBA or SAS RAID controller card on the server,
the storage
¡´enclosue provides not only capacity but
unprecedented performance for applications like High Definition
Video Editing or
¡´high speed transaction applications.
¡´For cost and capactiy consideration, Xtore
provides both 3U-16 and 2U-12 solutions, employing 3.5¡¨ drives.
For applications
¡´where power consumption, thermal or
environmental elements, and space limitations are
considerations, Xtore provides
¡´1U-10 and 2U-24 enclosures using 2.5¡¨ drives.
All of Xtore¡¦s SAS Disk Enclosures are designed with dual host
and cascade
¡´paths for further capacity expansion.
¡´Xtore enclosures support a scalable solution to
manage growing storage needs via efficient expansion. Each SAS
I/O
¡´Module supports a downlink cascade path with
four SAS channels maintaining 1,200MB/s speed.
¡´All of Xtore¡¦s SAS Disk Enclosures are designed
in a modular base, completed with redundant and hot-swap I/O
modules,
¡´fans, and power supplies for easy maintenance.
The systems support in-band SES (SCSI Enclosure Service) with
¡´embedded SEP for error and status reporting.
Each drive has activity and failure LEDs to indicate the drive
status. Firmware
¡´can be upgraded through in-band SAS ports or
serial port.
¡´For highest performance and reliability, systems
can be configured with dual I/O modules and high reliability SAS
drives by
¡´providing a 1,200 X 2 MB/sec speed and dual-port
failover capability. An application for a clustering transaction
server can
¡´apply the above scheme with the best throughput
and reliability. On the other hand, customers looking for
performance but
¡´not requiring redundancy can deploy the single
I/O module system with SAS drives without sacrificing
performance and
¡´reliability. Applications such as Video Editing
can use pure SAS interface for on-line storage usage. For the
lowest $/GB
¡´consideration, customers can apply the single
I/O module system with large capacity SATA drives to achieve the
best
¡´performance/cost investment. It is the best and most
cost-effective near-line or backup storage available.
