Page 9: Introduction To The Dr Series System
Introduction to the DR Series System The DR Series system documentation contains topics that explain how to use the Dell DR Series system to perform data storage operations and manage storage and replication containers. The DR Series system topics introduce and describe the DR Series system graphical user interface (GUI) that you can use to manage your backup and replication operations.
Page 10: Source Code Availability
NOTE: Always check for release notes on support.dell.com/manuals and read the release notes first because they contain the most recently documented information about known issues with a specific product release.
Page 11: Understanding The Dr Series System
NOTE: The 300 Gigabyte (GB) drive capacity (2.7 TB) version of the DR Series system does not support the addition of expansion shelf enclosures. Using Dell deduplication and compression algorithm technology, this system can achieve data reduction levels ranging from 10:1 to 50:1. This reduction in data results in less incremental storage needs and a smaller backup footprint. By removing redundant data, the system provides deduplication and compression that delivers: •...
Page 12: About The Dr Series System
About the DR Series System The Dell DR Series system is a solution designed to reduce your backup data footprint using a number of comprehensive backup and deduplication operations that optimize storage savings. Collectively, the DR Series system comes in two types: •...
Page 13: Internal Drive Capacity
• DR4100 system—which consists of preinstalled DR4000 system software on an modified Dell R720xd appliance platform. Internal Drive Capacity The capacity values listed in Table 1 represent the internal drive and available physical capacities that have been adjusted for the associated overhead in the DR4000/DR4100 system releases.
Page 14 the best results for routine and repeated data backups of structured data. Block-level deduplication works efficiently where there are multiple duplicate versions of the same file. This is because it looks at the actual sequence of the data– the 0s and 1s–that comprise the data. Whenever a document is repeatedly backed up, the 0s and 1s stay the same because the file is simply being duplicated.
Page 15 During replication, the system processes data storage requests from a specified source to a specified destination (also known as a target) that acts as a replica of the original source data. NOTE: Starting with Release 2.0, the DR Series system software includes version checking that limits replication only between other DR Series systems that run the same system software release version (DR Series systems running Release 2.0.x software can only replicate with other DR Series systems that run the same release system software).
Page 16: Data Deduplication And Compression
DR Series system software. Based on technology that is now part of the Dell Fluid Data Architecture, the DR Series systems provide a key component that performs backup, recovery, and data protection operations.
Page 17: Replication
DR Series system provides data deduplication and compression support for four data capacity points: 35 Terabytes (TB), 70 TB, 130 TB, or 270 TB. Dell DR Series NOTE: For a complete list of supported DMAs in the 2.0 release of the DR Series system, see the System Interoperability Guide for details.
Page 18: Reverse Replication
One system acts as the source and the other as a target in this replication pair (for example, acme-west and acme-east). When this type of relationship exists between distinct containers on two distinct DR Series systems, it can be considered bidirectional in the sense that: •...
Page 19: Reverse Replication: Alternate Method
Delete the replication relationship and re-create a replication relationship (restoring original source and target destinations). Under this scenario, a fraction of the data to be recovered is sent across the WAN link. This could speed up a remote restore significantly. However, there are some downsides to this type of scenario: •...
Page 20: Cifs
SMB that was originally developed and used by Microsoft. NOTE: The DR Series system does not currently support the Server Message Block (SMB), version 2.0. NOTE: For details on CIFS feature restrictions, see the Dell DR Series System Interoperability Guide , at support.dell.com/manuals. CIFS ACL Support Starting with the DR4000 system Release 1.1, the DR Series system software supports the use of access control lists...
Page 21: Existing Containers (Pre-1.1 Release)
default ACL is the same as that which would be created by a Microsoft Windows 2003 Server. Therefore, these new containers with the default ACL support the following permission types: NOTE: Any user that is part of BUILTIN\Administrators can edit ACLs on CIFS shares. The local DR Series system administrator is included in the BUILTIN\Administrators group.
Page 22: Unix Permissions Guidelines
NOTE: Dell recommends that administrators apply a set of permissions to existing containers that are similar to the way defaults are set for new containers. However, careful consideration needs to be given about granting access that addresses any specific security needs for individual users.
Page 23: Openstorage Technology (Ost): Dr Series System
OST via the Dell OST plug-in allows NetBackup and Backup Exec to take full advantage of such DR Series system features as data deduplication, replication, and energy efficiency. DR Series systems can access the OpenStorage API code through the plug-in, which can be installed on the media server platform choice you make (Windows or Linux).
Page 24: Openstorage Technology (Ost) Api
Supports different retention policies between source and replica NOTE: This capability to use OST, also known as DR Rapid Data Access within Dell, adds tighter integration with backup software applications, such as the two Symantec OpenStorage-enabled backup applications supported in this release: NetBackup and Backup Exec.
Page 25: Software Components And Operational Guidelines
Backup Exec: version 2010 Release 3 (Windows 2008 R2, 64–bit), and 2012 (Windows 2008 R2, 64–bit). NOTE: The Dell DR Series system licensing is all-inclusive, so that no additional Dell licensing is required to use OST or the optimized duplication capability. The Dell OST plug-in that gets installed on a supported Linux or Windows media server platform is a free download from Dell.
Page 26: Dr Series System And Data Operations
DR Series System and Data Operations Data is stored and resides on the Dell DR Series system, a two-rack unit (RU) appliance, which comes preinstalled with the system software. Starting with the 2.0 release. the DR Series system comes in two types: •...
Page 27: Dr Series Expansion Shelf
1 Terabyte (TB), 2 TB, or 3 TB hard drive capacities. The physical disks in each expansion shelf are required to be Dell-certified Serial Attached SCSI (SAS) drives, and the physical drives in the expansion shelf uses slots 1–11 configured as RAID 6, with slot 0 being a global hot spare (GHS).
