• OST Automatic Image Replication - If you are using Symantec
NetBackup 7.1 or higher, you can configure an LSU for Automatic
Image Replication. If enabled, data on an LSU is automatically
replicated to a remote LSU that resides on a DXi in a different
NetBackup domain (see Replicating OST Data on page 316).
• Concurrent Optimized Duplication - With Concurrent Optimized
Duplication, as data is written to the storage server, it is
simultaneously replicated to the target DXi. When optimized
duplication or Automatic Image Replication subsequently occurs,
the operation is more efficient because a portion of the required
data has already been replicated to the target storage server (see
Replicating OST Data on page 316).
• DXi Accent Improvements - DXi Accent supports Windows based
media servers running Symantec Backup Exec or NetBackup. In
addition, data sent from the media server to the DXi can be
encrypted using AES (Advanced Encryption Standard) encryption
methods (see DXi Accent on page 343).
•
Fibre Channel Port Management
- Detailed port layout diagrams
make it easy to identify Fibre Channel Ports on the back of the
system. Also, you can change the mode of a Fibre Channel port to
initiator or target (see FC Initiators and Targets on page 352).
• Consolidated Job Scheduler - All scheduled functions of the DXi
are now managed on the Scheduler page, including the scheduling
of replication, replication throttling, e-mail reports, healthchecks,
and space reclamation (see Scheduler on page 353).
•
VLAN Tagging
- You can enable VLAN tagging and Jumbo Frames
for any configured network interface on the DXi (see Network on
page 366).
• Space Reclamation Improvements - Scheduled and on demand
space reclamation has been tuned for increased performance, while
automatic space reclamation during low space conditions provides
maximum free space recovery. Also, the blockpool automatically
reuses free bytes when ingesting data (see Space Reclamation on
page 435).
