The following list describes the new features and enhancements in the current release:

Increased capacity availability for the DR2000v system — This release adds the ability to support 12 TiB capacity in the DR2000v. Refer to the Dell DR Series System Interoperability Guide for detailed information about the increased capacity availability and the supported platforms and operating systems for the DR2000v.
Hyperscale version of the DR2000v — A DR Series hardware system with a Hyperscale license can now function as a regular DR Series system with full DR Series capabilities.
DR2000v registration with DR Series system hardware — This version of the DR2000v can be registered with a DR Series hardware system running either or release versions of the DR Series software.
New cleaner statistic for CLI — When using the stats –cleaner CLI command, the last time the cleaner completed is now displayed. Release

For your reference, the following list describes the features and enhancements that were included in the previous release:

FIPS 140-2 support has been added.

HTTPS requirement — Starting with release, the DR Series system Web interface is accessible via HTTPS only; all HTTP calls to port 80 are redirected to HTTPS (port 443). This requires JavaScript as a prerequisite for browsers. If you attempt to access the DR Series system on port 80 with JavaScript disabled, you are asked to enable JavaScript and the following message appears in the browser:

This application cannot run with JavaScript disabled. Please enable JavaScript.

NVRAM patch — A new hardware check has been added in this release to detect super capacitor failure.
Samba patch — This release includes the Samba patch that addresses the Samba “CVE-2015-0240” vulnerability.
Configurable RDA opdup retries — In the event of a connection failure, the number of RDA opdup retries is now configurable. Instructions for configuration are listed as follows.

For Windows:

For Unix:

A field called “Latest mtime of replicated files” has been added to the daily container stats report. You can optionally configure the DR Series system to send this report every day. This additional field specifies the latest modification time of the last file that is in-sync with the target. It implies that all files, which had final modifications completed prior to the time shown in the report, are also in-sync with the target.

You can enable the daily container stats report when you register the system by clicking the button, Notify me of [DR Series] daily container stats reports.

You can also manage the daily container stats report via CLI by using the following commands:

alerts --email --daily_report <yes/no>

alerts --email --daily_report_time <time>

Updated RDA platform support — With Release of the DR Series system software and NetVault Backup 11.0, RDA is supported on the Solaris Sparc and Intel platforms. A standalone RDA installer is also available.
CIFS and NFS accelerator support for NetBackup 7.7 — NetBackup 7.7 has been tested for CIFS and NFS accelerators.
RMAN Oracle support — RMAN Oracle 12C is now supported.
Updated Veeam feature support — The following advanced features of Veeam 9 have been qualified.
Moonwalk 9.3 support — Moonwalk 9.3 update1 has been qualified for CIFS and NFS.
HP Data Protector support — HP Data Protector 9 has been qualified for this release.
vRanger 7.3 support — vRanger 7.3 has been qualified with the default RDA plugin.

3.2 Release

For your reference, the following list describes the features and enhancements that were added in the 3.2 release:

Virtual Tape Library — This release of DR Series system supports the creation of four virtual tape library (VTL) containers. This is a new container type introduced in this release. The VTL emulation will be for two types of libraries:

Each library will be initially instantiated with 10 tapes of either of the following tapes sizes 10GB, 50GB, 100GB, 200GB, 400GB and 800GB. Additional capability is provided to append new media (tapes) as required.

Support for NDMP and iSCSI backup protocols for VTLs — VTLs can be accessed by either NDMP or iSCSI protocols. The DR VTL will be represented as an iSCSI target to iSCSI software initiators running on media server operating systems. In the case of NDMP, the DR will host a NDMP tape server which will provide access to the VTLs serviced by the NDMP tape server. For supported Data management applications for both NDMP and iSCSI VTL access, see the Dell DR Series System Interoperability Guide version 3.2.
Encryption of Data at Rest — Data backed up to the DR appliance can now be optionally saved in an encrypted format. When the encryption option is enabled, data is encrypted before it is saved to disk. The DR supports Industry standard FIPS 140-2 compliant 256-bit Advanced Encryption Standard (AES) encryption algorithm for encrypting and decrypting the user data.  Key management is done via Static mode or an internal mode. In static mode, a global, fixed key is used to encrypt all data. In internal mode, lifecycle management s performed where keys are rotated at periodic intervals which can be set by the administrator.
RFE: Continue OFSCK from nearest logical point if it has been stopped during regular run (OFSCK restartability) — In this release OFSCK has been enhanced to restart from the point it left, if it is interrupted due to a crash or any other reason. The restartability is currently provided in phase-1 of OFSCK where datastores are being crawled.
Replication: Performance improvement for overwrites and appends — As part of improving the replication process a change has been made wherein only the changed blockmap entries for replicated data files is sent over the wire in lieu of the entire blockmap.  This improves the replication performance and replication completion issues seen for constantly updating source data files are alleviated.
Replication: Multi Connection support (hidden feature, can be enabled through customer env) — In prior releases a single connection is maintained between the source and target container pair. This enhancement is being added to enable multiple TCP connections over which replication or RDA opd-up can occur in parallel, between a pair of containers. The number of connections increased is per container for container replication. The maximum TCP connections will be 64. It can be set through env variable (REPL_CLNT_MAX_CONNS).
250 million file support — This release will now support up to 250 million files for DR appliances hosting internal drives greater than 2TB.
Hyperscale: Supports DR4x00 and DR6000 as a License server for DR2000VMs (up to 3000) — This release will now support DR4x00 and DR6000 systems as license server for up to 3000 DR2000v systems.
RFE: Provide per-job de-dupe stats at RDA/OST plug-in — Supported Symantec (OST) and Dell (RDA) Data Management Applications will now report de-dupe savings as part of backup logs and events.
RFE: Enhance ODIV to report when the container was last verified for Data Integrity — Advanced Data protection reporting will show when the container was last verified for Data integrity.
Container creation Wizard in GUI — This release has a new wizard for creation of containers and assigning relevant properties such as protocol and DMA access and marker types assignments.
Support for Rapid CIFS and Rapid NFS on all platforms — This release has support for Rapid CIFS and Rapid NFS on DR4x00, DR6000 and DR2000v platforms.

CIFS usage graph shows that there are CIFS writes, when running iSCSI I/O only.

The stats reported on the iSCSI graph are accurate. Due to a bug false stats getting reported on the CIFS chart which can be ignored. This issue will be fixed in the upcoming 3.2 hot-fix.


Changing machine host name doesn't get updated in all components

This issue does not cause known failures to the normal operation of the DR and can be ignored. It will be fixed in a future release.


Cannot join into domain by adding DR into multiple OUs

In the authenticate command type as follows:--ou topLevelOU/middleLevelOU/LowerLevelOU/TargetOU 


Specific umount options do not work for Rapid NFS.

The -l and -f options are not supported in the rdnfs unmount procedure.


Replication traffic that is configured to go through an assigned bond may still run through the default bond (bond0).

If you want to run replication traffic through another bond interface, contact Technical Support to update the route.


Manual modifications made to the Rapid NFS rdnfs.cfg file are not preserved between plug-in updates.

Manually modify the rdnfs.cfg again after upgrading the plug-in.


An NVBU backup will stop if the DR Series system goes into maintenance mode as it moves into a read-only condition when this occurs.

Restart the datacopy operation after the DR Series system enters the operational mode.


Advanced networking allows you to change the IP of an interface that is part of a replication link.

Understand your current configuration before adding new advanced networking configuration so that you do not impact the current system configuration.


When you try to get replication statistics, the system displays the Software error: Use of uninitialized value in division (/) at line 3548 error.

This is due to the replication target not being in an operational state. Correct the replication target and refresh or use the CLI. The information is available by using the command line. We will correct this error in a future release.


After you install the Rapid CIFS plugin and replication operations are performed, you receive a blue screen and the following error: STOP 0x00000027 (parameter1, parameter2, parameter3, parameter4) RDR_FILE_SYSTEM

This is a Microsoft bug that occurs on shared network resources on a computer that is running Windows Server 2008 R2 or Windows 7. To fix, see Microsoft Knowledge Base article 2584874.
