LSI™ MegaRAID® LSIiBBU08
Intelligent Battery Backup Unit for 6Gb/s MegaRAID
SAS Controller Cards
Product Brief
K E Y F E A T U R E S
Helps protects integrity of cache in
the event of power or server failure
Higher maximum ambient tempera-
ture tolerance than previous genera-
tion battery backup units
Multiple modes of operation and
retention times
Transparent and shorter learning
cycles
For use on all existing 6Gb/s
MegaRAID controllers
Customize mounting location in
chassis with remote mounting
options
Higher Ambient Temperature Toler-
ances and Increase Serviceability
The LSIiBBU08 can tolerate higher ambi-
ent temperatures around the battery
backup unit as compared to the previ-
ous generation battery, with tolerances
of up to 55°C versus 45°C for ambient
cell temperature. There is also a remote
mount option available which allows
customers who have limited chassis
space or a constrained thermal environ-
ment to reposition the battery backup
unit away from the RAID controller card
for cooling purposes.
A lower temperature environment will
generally help prolong the service life of
a battery backup unit, while high tem-
peratures and extreme conditions will
shorten the battery life. For example, if
the battery is set to a 12-hour DRT and
45°C mode, it may not require replace-
ment for the life of the RAID controller1.
However, using a 48-hour DRT and 55°C
mode with your battery may cause a
situation where the battery requires
replacement after the rst year of use2.
Multiple modes of operation and
retention time
The LSIiBBU08 allows for multiple
modes of operation, which let the user
select a shut-o data retention time
(DRT) of 12, 24, or 48 hours with as-
sociated operating temperatures, learn
cycles, and estimated service lives. The
MegaRAID controller rmware will use
the LSIiBBU08 until it calculates that
the battery can only guarantee cache
data for the selected period of time in
the event of power loss to the server.
With previous generation MegaRAID
batteries, there was only one mode of
operation with a retention time of 72
hours. By oering these multiple modes
of operation, the LSIiBBU08 provides the
exibility to select the optimum DRT,
performance based on cache policy, and
maximum operating temperature that
best ts their specic application and
environment.

1. Life of the controller is estimated at three years based on
standard warranty
2. Estimated Calculation based on; 1GB (5 chips) DDR2 and one
1500 mAh Lithium ion cell, individual results may vary.
3. Based on internal calculations regarding estimated battery life
and losses over time, individual results may vary.
Note: BBU warranty is still one year for all modes of operation.
