Single-controller,
8-drive bay SATA RAID Subsystem
EonStor A08U-C2411
The new, highly versatile EonStor A08U (Cube) RAID subsystems are the latest
products in Infortrend's family of highly acclaimed SATA RAID products. The
subsystem can be conveniently configured as either a desktop or a tower
subsystem and its modular architecture is designed for ease of maintenance
and protection for redundant disk array operation.
The 320MB/s SCSI host channel is interfaced through two (2) separate VHDCI
ports in a dual-stack configuration. The VHDCI ports can be either connected to
a host computer or cascaded to a second Cube subsystem. A maximum of four
(4) Cube subsystems can be cascaded together. In the desktop configuration
four (4) subsystems can be stacked on top of each other.

The eight (8) hot-swappable drive bays
accommodate 3Gbps SATA-II disk drives and
are routed through a drive-plane board to
the RAID controller unit in the back.
Two (2) redundant, single-fan cooling
modules and a 250W power supply unit (PSU)
module ensure a stable subsystem operating
environment.
. Up to 1GB SDRAM cache memory
. RAIDWatchR : Browser-based GUI manager on
Windows and Linux platforms
. Auto Cache Flush and Auto Shutdown when critical
conditions are detected
Architecture
Based on an architecture designed for highthroughput applications, the subsystem is capable
A variety of management interfaces are
available: the array can be accessed
through the LCD keypad panel, RS-232C
terminal, telnet, or remotely through the
Java-based RAIDWatch manager. Users are
constantly aware and automatically notified
of array status using any or all of the
following notification methods: email, fax,
LAN broadcast, SNMP traps, MSN messaging,
ICQ, SMS short messages, and the
configuration utility screen.
of very high levels of performance. Its 64-bit
separate-bus backbone is built around dedicated
XOR engines running at twice the data bus speed.
The calculation of parity and distribution of data
can be optimized with the free association between
individual logical arrays and different optimization
settings.

Featuring a 64-bit, 133MHz memory bus, the
unparalleled bandwidth makes the subsystem's high

distributed at a burst rate up to 1066MB/s. The dualindependent PCI bus design virtually eliminates all
imminent bottlenecks on I/O traffic, providing
sufficient throughput for a wide range of applications
on workstations, Windows 2000/XP-/2003, Linux-, or
Unix-based servers. These applications include diskto-disk backup, video-on-demand, CCTV (closed
circuit TV), stream editing, and others.

Intelligent Drive Handling (IDH)
If bad blocks occur on two member drives of an
array, the integrity of the stored data is
endangered. Media Scan, Infortrend's innovative
intelligent drive handling function, repairs and
retrieves data from the affected and adjacent
sectors. Media Scan handles low quality drives in
both the degraded mode and during the rebuild

Auto Switch Cache Policy and Auto
Shutdown
When a RAID controller detects conditions that
exceed the preset thresholds, the following actions
will be initiated to protect the hardware:
Cached data will be automatically flushed and the
array's caching mode will be switched from write-
If the conditions persist past a preset period of time,
auto shutdown of the controller will commence.
Impressively, all the thresholds associated with this
mechanism are user configurable and, once a
subsystem manager restores the normal operating
conditions, the caching mode will change back from
write-through to write-back mode.
