Overview
This exciting new product allows for fast and easy
JBOD expansion to the new line of
Aberdeen Storage
Servers with SAS Expansion. Storage servers
with external either one or two external SAS ports
may connect to these JBOD at a substantially lower
cost than purchasing a new server. Each
external SAS port can connect one of these JBOD and
then each JBOD can connect to another JBOD.
The maximum supported number of JBOD in any daisy
chain is four. In practice, the 3U
X315 and
X319, the
4U X419 and the 5U X527 each have a single
compatible SAS port. Therefore up to
four JBOD may be attached. The 6U X634, X841 and 8U
X881 each have dual compatible SAS ports and may
actually add up to eight more JBOD!
High Performance and
Scalability
Aberdeen storage servers and JBOD enclosures provide
a scalable solution to
manage growing storage needs via efficient
expansion. The maximum performance per host connection is
1,200MB/sec, which is higher than a single 4G or
even 10G Fibre Channel connection. The performance
of the bus is achieved by combination of four SAS
channels with each supporting 3Gbps full duplex
speed. Together with the high-speed SAS
RAID controller card in the storage server, the storage
enclosure provides not only capacity but
unprecedented performance.
16TB or 32TB RAID Volume Support
External SAS expansion ports on the compatible
storage servers are fully capable of controlling
four 16TB RAID arrays in a JBOD daisy chain.
Also two JBOD may be used together to create a
single 32TB RAID array! And of course 2 more
may be daisy chained on these for another 32TB
array.
Easy Maintenance and Management
All Aberdeen XDAS and JBOD solutions have a similar
modular design. Components like fans, power
supplies and I/O modules have easy swap features
with convenient thumb screws. The JBOD supports 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.
