The 3ware 9550SX PCI-X to Serial ATA II RAID 
controller delivers over 800 MB/sec RAID 5 reads
and exceeds 380 MB/sec RAID 5 writes, making it
200% faster than the industry leading 3ware
9500S RAID controller.  7th generation StorSwitch

™

non-blocking switch fabric technology and
sophisticated SATA II features including 3 Gbps
transfer speed, Native Command Queuing, and
Port Multiplier support drive this unmatched 
performance. 

AMCC’s exclusive StreamFusion

™

caching algorithms

assure the most efficient use of available band-
width when transferring multiple simultaneous
data streams to an array. The on-board PowerPC
processor manages RAID controller functions,
which allows the host system CPU to manage 
system applications.  

The 9550SX’s advanced RAID features and power-
ful performance architecture make it the ideal
controller for mid-range database applications,
print and file server applications, and vertical
applications including NAS storage, web servers,
cluster servers, supercomputing, near-line backup
and archival, security systems, and audio and
video streaming applications.

StorSave

™

, AMCC’s data reliability platform, delivers

a comprehensive suite of advanced data protec-
tion and data recovery features, combined with 
a Battery Backup Unit.  The BBU, complete with 
write journaling, provides added data protection
in the event of a power outage.  Reliability is 
further strengthened with features like out of 
band (OOB) staggered spin up, SMART disk drive 
monitoring and reporting, hot spare/hot swap,
automatic rebuild, and dynamic sector repair.  

Enterprise RAID features such as on-line capacity
expansion allows flexible scalability of the RAID
array, while RAID level migration allows the 
reorganization of arrays when data protection
requirements change.  Other scalability features
include 64-bit LBA support for addressing arrays
greater the 2 TB and support for multiple cards
within a system for large storage requirements.
The 3ware 9550SX controller supports RAID levels
0, 1, 10, 5, 50, Single Disk, and JBOD.  

AMCC’s award winning Multi-lane

™

SATA cabling 

system significantly reduces the number of cables
needed to connect controllers, backplanes,
and  standard SATA drives. Multi-lane combines 
four SATA ports into a single locked connection. 
A 16-port controller requires only four cables 
with Multi-lane. A reduced cable count facilitates 
systems scalability and improved airflow.
