Release Notes

a. The Standard STK L700 library with 10 Ultrium 3850 LTO4 drives
b. An OEM – Dell version of the same library.
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.
