Product Introduction ETERNUS DX60 and DX80

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.

Dynamic LUN Migration

LUNs can be migrated on the fly to

Other drives and different RAID groups

Other drives and different drive types (e.g. SAS to NL SAS, SAS to SSD)

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
