Intelligent multi-level cache algorithm with
adaptive delayed write & read ahead functions
Intelligent Battery Backup Unit
BBU Support for even more Data Reliability
72 Hours of Cache Memory Protection
●
GDBBU, ICP Controller plus ICP Battery
Backup Unit, includes BBU support in hardware and
firmware
●
With GD BBU functionality can optionally be
updated by putting the battery (ICP BBU) into action
●
RAID cache holds all data and stores it even in the
case of power failure, at system/controller restart all
data in cache will be written back to hard drives
●
Lithium Ion Battery with typ./min. hold time of
72 hours (appropriate handling required), depending
on the used memory module
●
Intelligent battery management via ICP RAID software
for monitoring current, voltage, temperature and
actual capacity of battery, for instance
