• 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, then
start secure shred. During secure shred, all residual data associated
with the deleted files is securely erased from the disk drives and is
overwritten with random patterns (see
The following enhancements were introduced in DXi 2.1.x Software:
• Additional OpenStorage (OST) Improvements - Enhancements
include support for optimized synthetic full backups, and support
for HP-UX 11i v3 IA-64 platforms (NetBackup only).
• Replication Throttling and Scheduler - With replication throttling,
you can configure the DXi to limit its outgoing data replication
bandwidth to a specified maximum in order to avoid network
contention. Use the new Scheduler page to set up a recurring
schedule for replication throttle, and to manage schedules for space
reclamation and healthchecks.
• AES 256-bit Encryption - When sending replicated data to a target
system, the DXi can take advantage of 256-bit encryption for
stronger security.
• New CLI Functionality - The command line interface (CLI) supports
new and updated functionality for enabling symlinks and hard links
on NAS shares, enabling SMB server signing for NAS shares,
mapping OST IP addresses, scheduling replication throttling, and
performing advanced configuration of network interfaces.
• Improved Space Reclamation Process - The space reclamation
process now better adjusts its use of system resources, consuming
fewer resources during data ingest and performing space
reclamation more quickly when more system resources are
available.
The following enhancements were introduced in DXi 2.0.x software:
• Inline Data Flow - The new, inline data flow enabled by the DXi
2.0.x 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
page 8).
• OpenStorage (OST) Improvements - Enhancements include
increased total performance, including writes, reads, and
replication; simplified deployment (see
