What’s New in this Release
Import Mode
Import Mode allows you to import data directly to the lowest configured tier of storage.
Advanced Mapping Display
An option exists to allow advanced mapping information to be displayed. By default, this
option is turned off.
Storage Center 5.2.1
RAID 6
In addition to RAID 10 and RAID 5-5/5-9, Storage Center allows you to select RAID 6 for
any storage tier. RAID 6 provides greater storage redundancy and efficient use of disks.
Secondary DNS Server
Users now have the option of entering a secondary DNS server. If a path is not available to
the primary DNS server, the Storage Center connects to the secondary DNS server.
Import from External Device
Previously, a synchronous replication license was required for data to be loaded from an
external device. Now the command to Import from an External Device and Classify Disk as
External are available without a synchronous replication license. Import from External
Device uses synchronous replication to import data from a non-Storage Center device.
Storage Center 5.1
System Dashboard
The license window that appeared in previous versions of the System Manager is replaced
with a System Dashboard that displays used and available storage space, and a history of
storage use. The Dashboard lets you monitor your space more efficiently. The license
window is available from the Help menu.
Storage Center 5.0
Virtual Ports
Virtual Ports eliminate the need for reserve ports. When operating in Virtual Port mode all
front-end ports accept IO.
Consistency Groups
Consistency Groups create a synchronized Replay of all volumes within the consistency
group while the IO stream on all volumes is halted. This creates a consistent data set.
Consistency Groups can also be replicated to other Storage Centers.
Mapping
Storage Center adds the ability for you to identify the operating system of each server so
that it can map Volumes to Servers based on the rules of the operating system of the server.
