The HiperDisk-42 JBOD subsystem leverages
multiple LSI SAS Expander chips to provide
maximum drive capacity / density and
maximum throughputs. The series features
high-capacity/high-density with 42 hot-swappable
SAS/SATA II hard disk drive bays in
a 19-inch 4U rackmount unit, scaling
to a maximum storage capacity in near
the 100 terabyte range, and capable
of providing up to 4000MB/sec.
Feature
Hi-Lites:
- Cable-less IO module and backplane(bottom-plane)
- Menu-driven front panel display.
- Innovative Modular architecture.
- Broad range of SAS RAID controllers
support.
- Very High Capacity Density Solution
yet the most cost-effective solution
- best rack space and power economy
and efficiency.
- Solid mechanical design and making
eliminates harmonic vibration, which
enhances the over all reliability
and availability.
- Optional Dual IO Modules for redundant-path/path-failover,
or share the box between two systems.
- Include Interposer/MUX adapters
for SATA II disks to utilize Dual IO
Modules for redundant-paths.

Typical Applications for Dual
IO Modules:
Application-1: Redundant Path-Failover.
With SAS disks installed, when used
with LSI SAS MegaRAID such as 8880EM2
or 8888ELP, it supports redundant path-failover
between two SAS connections from a single
SAS RAID adapter. Such function does
not require any special configuration;
it is natively supported by the SAS
RAID adapters and the Dual IO Modules.
Application-2: Share Device
between multiple controllers.
With SAS disks installed or
SATA disks installed with interposer/MUX
adapters, the In-port of each IO Module
can connect to a different SAS RAID
adapter, so some of the 42 disks can
be assigned to one SAS RAID adapter
and the rest be assigned to the other
SAS RAID Adapter. Be aware, this is
“sharing the device”, but not “sharing
the disks”. There is no disk that can
belong to both SAS RAID adapters.
Application-3: Bandwidth Aggregation
for Extreme Performance
Each IO Module can be configured
as 1 x In-port or 2 x In-port. When,
the IO Module is configured as “2 x
In-Ports”, the JBOD has total of 4 x
In-Ports, and you can use up to 4 x
SAS RAID Adapters in a single Host Computer,
with each SAS RAID controller owes about
10 or 11 disks, and delivers about 1000MB/sec
transfer rate per controller. Then,
use the OS to stripe across all volumes
from 4 SAS RAID controllers to achieve
the extreme performance by bandwidth
aggregation. |
