StorSave™ with BBU
Technical Brief
System Reliability  
The StorSave platform enhances controller  
performance and increases SATA storage 
system reliability by offering a unique set of 
data protection and data recovery features, 
combined with a BBU.
3ware uses both controller cache and disk 
cache during SATA RAID operations, which 
strengthens array performance during optimal 
usage as well as degraded RAID operations 
including faster rebuild times.
Disk Based Features  
Dynamic sector repair increases drive  
reliability with on-the-fly correction of drive 
media errors in redundant arrays. Drives are 
never degraded because of soft media errors.
Drive power-on reset detection reliably  
detects unplanned drive power cycles through 
ATA security commands and automatically 
degrades a drive that may have potentially  
lost data.
Extensive drive timeout recovery is an  
intelligent timeout algorithm that maximizes 
drive error recovery within server operating 
system constraints thereby reducing transient 
errors in drives and the controller. StorSave 
enhances the reliability of drive detection  
during controller boot up with out-of-band 
(OOB) signaling retry, a low-level controller/
drive handshake.
BBU for Data Protection  
The StorSave Platform supplies on-board 
memory protection and sends power to the 
cache memory module in the event of a system 
power loss. It enables the use of controller and 
drive write caching for best performance while 
preventing data loss during critical events.
Secondary power loss support safeguards data 
against on-site power interrupts and during 
routine system power up. Missing array detection 
eliminates silent data loss by retaining  
unwritten data from an unusable array until  
the user intervenes. Cached write data is not 
LSI 3ware’s revolutionary combination of powerful reliability
enhancements and a BBU maximizes data protection without  
sacrificing performance
