Battery Free Cache Protection (1)
Battery Free Cache Protection (1)
Reduced maintenance window
SCU* is maintenance free for 5 years
• Battery replacement was required every
three years in the previous models
Avoid data loss during extended power
outages
Migrating cache data to a nonvolatile memory
ensures unlimited data retention time
• Previously battery back up supported cache
data for approximately 96 hours
Cached write performance recovered
almost immediately after power restoration
SCU recharge time about 3 minutes
• Exact battery recovery time depends on how long the power has been
unavailable
In the event of a power failure, the data is migrated from cache to a nonvolatile RAM.
For improved reliability, power for the migration process is supplied by a SCU* (System
Capacitor Unit) rather than a battery
In the event of a power failure, the data is migrated from cache to a nonvolatile RAM.
For improved reliability, power for the migration process is supplied by a SCU* (System
Capacitor Unit) rather than a battery
• SCU is a unit with electric double layer
capacitor. Electric double layer
capacitor has the advantages of being
very resistant to degrading and by
providing a short recharge time
compared to traditional batteries.

LUN Concatenation
LUN Concatenation
Can expand the capacity of existing LUN by creating new LUN
and concatenating it to an existing LUN
Data on existing LUN will be kept
• Independent of RAID level in use
• Minimum required capacity of a LUN is greater than 1 GB
• Maximum number of LUNs that can be concatenated is 16
• Maximum capacity of a concatenated LUN is 32 TB
