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.
