RAID Levels RAID 1+0 is recommended for

business databases that are updated frequently Select RAID 1+0 for systems

that require high reliability and high performance

RAID 5 (RAID 5+0 if enough disks are available) or RAID 6 is recommended for data that requires less random performance or for systems where there is a high level of reading Global and dedicated Hot Spares are available, all disks can

be used except the system disks

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 three minutes

• Exact battery recovery time depends on how long the power has been unavailable


• 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.

Control of a Failed Disk Two different modes are supported Rebuild

• ETERNUS DX rebuilds the data of a failed drive from the remaining drives and writes it to a Hot Spare • When no Hot Spare is available

ETERNUS DX rebuilds the data after the defective drive is replaced

• Redundancy of the RAID Group is recovered after rebuild is completed

Copy Back • After redundancy of the RAID

Group is re-established, data is copied back from the Hot Spare to the replaced drive

Global and Dedicated Hot Spare Dedicated Hot Spare (DHS) disk Has to be assigned to a specific

RAID Group When a disk of a RAID Group with

a Dedicated HS fails, then this Dedicated HS is selected and used to rebuild the RAID Group

Global HS (GHS) Used by all RAID Groups When a disk in any RAID Group fails

and there is no Dedicated HS available, a Global HS is used to rebuild the RAID Group

Logical Device Expansion Expand capacity (free space) of a RAID Group by adding

unused disk drives RAID level can be changed


Expands

30

LUN Concatenation LUN capacity can be expanded by using LUN concatenation Consolidates unused areas in the same or across multiple

RAID Groups for efficient use of drives NOTE: After LUN Concatenation it may be necessary to adapt

the Operating System and/or application to recognize the increased LUN size Maximum LUN capacity is 32 TB Minimum LUN capacity is 1 GB Maximum number of LUNs that can be concatenated is 16 Able to mix different RAID levels

without interrupting operation Migrate existing LUNs from a RAID Group to a different one Migration between different RAID levels RAID migration to expand LUN capacity Migration is transparent from server point of view

data can exist in the same RAID Group

Possible to encrypt an existing unencrypted Volume For redundancy, the Data

Encryption configuration is saved on the controller(s) and on the disks

Power Saving Eco-mode (1) Reduces power consumption When drives (RAID Groups) are used only a few hours per day

(for example for backup), Eco-mode is an effective way of saving power Drive spin down can be scheduled

• Drives are spun down if idle during the schedule time Drives are spun up automatically when accessed Can be managed with GUI or CLI of ETERNUS DX series
