The EonStor subsystem combines 
either 2Gbps Fibre (A12F) or Ultra 
160 SCSI (A12U) host channels with 
12 SATA drives in a storage 
subsystem. The system design 
provides users massive storage 
capacity with SATA benefits such as 
high performance and full bandwidth

ES A12U-G1A3      2 SCSI-160     12 SATA-1

Featuring a 64-bit 133MHz memory 
bus, the unparalleled bandwidth 
makes the subsystem's high data 
throughput more than sufficient for 
small-to-medium sized servers or 
workstations.  Data can be distributed 
at the burst rate up to 1066MB/sec.  
The dual PCI bus design virtually 
eliminates all imminent bottlenecks on
IO traffic, providing sufficient 
throughput for a wide range of 
applications on SCSI-based PCs, 
single-user workstations, NT, Linux, 
or Unix-based servers. These 
applications 

include disk-to-disk 

backup, Video on Demand, CCTV, and 
stream editing. 

Media Scan is an innovative 
intelligent drive management function 
that can be used for data retrieval 
from the occurrence of bad sectors on 
hard drives. If two bad blocks occur on 
two member drives of an array, the 
integrity of the stored data will be 
endangered.  Intelligent drive 
management capabilities can be used 
to retrieve data from the damaged 
sectors.  Media Scan is able to handle 
low quality drives in both the 
degraded mode and during the rebuild 
process.  Other intelligent drive 
handling features, which provide 
further data security, include the 
transparent resetting of hung hard 
drives, power-failure management 
and bad  drive handling during LD 
expansion.    

The RAID controller embedded in the 
EonStor RAID subsystem ensures 
unprecedented data security for ATA 
RAID.  The available models (see 
table) in these series provide users 
with versatile options enabling them 
to purchase a subsystem that will 
meet their needs.  

The SATA models enables users to 
use serial ATA drives in the 
subsystem whereas the availability 
of a separate dongle kit allows for the 
use of PATA drives providing a less 
expensive option for an economic yet 
reliable RAID subsystem.  

Running on an architecture trusted 
by the most demanding applications, 
the subsystem is equipped with 
intelligent algorithms capable of 
bridging the point-to-point bandwidth 
of SATA drives with high speed host 
channels.  Its separate-bus 
backbone is built around the 
dedicated XOR engines capable of 
fast parity calculation and I/O 
turnarounds.  The distribution of data 
can be optimized with configurable 
array settings and the free 
association between individual 
arrays and different optimization 
modes.  

to each connected device, in a safe 
subsystem environment where a 
highest level of data availability is 
assured.
