Secure Shred
- With Secure Shred, you can securely and
permanently erase sensitive data stored on the DXi. To securely
erase data, first delete files on NAS shares or storage servers, or
erase tape cartridges on VTL partitions, then start secure shred.
During secure shred, all residual data associated with the deleted
files or cartridges is securely erased from the disk drives and is
overwritten with random patterns (see
Secure Shred
on page 443).
Enhancements in
Previous Releases
The following enhancement was introduced in DXi 2.1.2 Software:
•
Data-at-Rest Encryption
- Data-at-Rest Encryption secures all data
stored on the DXi8500, including file data and metadata,
configuration files, and the DXi software and operating system.
Data-at-Rest Encryption ensures that a hard drive that is physically
removed from the DXi cannot be read using another system or
device (see
Data-at-Rest Encryption
on page 392).
The following enhancements were introduced in DXi 2.1 Software:
•
Inline Data Flow
- The new, inline data flow enabled by the DXi 2.1
Software deduplicates data as it is ingested into the DXi appliance.
Optimized for the new generation of purpose-built DXi hardware
platforms, it provides enhanced performance and more efficient
dynamic use of system resources (see
Data Reduction
on page 8).
•
DXi Accent
- Quantum’s DXi Accent software accelerates backups
and reduces network bandwidth requirements by distributing
deduplication between the backup server and DXi appliances. With
DXi Accent, backup windows are reduced and network bottlenecks
are eliminated (see
DXi Accent
on page 343).
•
OpenStorage (OST) Improvements
- Enhancements include
increased total performance, including writes, reads, and
replication; simplified deployment (see
Manage Users
on page 333);
support for optimized synthetic full backups; and dynamically sized
LSUs with no hard size limit (see
LSU
on page 327).
•
Automatic Replication Trigger
- In the Directory/File Based
Replication, a file is automatically replicated after it is closed (CIFS
shares) or after several minutes of inactivity (NFS shares) (see
Directory/File or Cartridge Based Replication
on page 167). There is
no need for scripting to execute this function. This action makes
files at the target available for access without a local recovery
operation.
