Rapid Data Storage (RDS): DR Series System
Rapid Data Storage (RDS) is developed by Dell Quest and provides a logical disk interface for use with network storage
devices. RDS allows for better coordination and integration between DR Series system backup, restore, and optimized
duplication operations with Dell Quest NetVault Backup (NVBU).
The DR Series system and NVBU integration is done using the Rapid OFS (ROFS) plugin developed by Dell. The ROFS
plugin allows NVBU control over backup image creation, deletion, and duplication. RDS allows deduplication and
compression operations to happen on the client-side so that network traffic can be reduced.
The RDS protocol allows the supported backup applications to communicate directly with the DR Series system and
determine whether a specific chunk of data already exists on the system. If the data already exists, only the pointers
need to be updated on the DR Series system, and the duplicate chunk of data does not need to be transferred to the
system. This process provides two benefits: it improves the overall backup speed, and also reduces the network load.
Rapid OFS (ROFS) API
メモ: Rapid OFS (ROFS) is an internal API used by RDS. The term ROFS is not used in the web user interface or CLI.
The Rapid OFS (ROFS) API is an application programming interface that allows disk-based devices like the DR Series
system to natively integrate with the Dell Quest NetVault Backup. For example, because the DR Series system supports
both data deduplication and replication, the ROFS API allows these supported DMAs to use the DR Series system
appliance features and duplicate the optimized data from one storage appliance to another.
Unlike replication configured directly on the DR4
x
00 for CIFS and NFS, the ROFS API allows the Data Management
Application (DMA) to be aware of the replication copy. The ROFS API allows the DMA to restore directly from any
DR4x00 that are on the same subnet and can communicate with each other.
The ROFS API enables the writing of data to disk and allows NVBU (the DMA) to interact with the DR Series system (the
data backup and deduplication device) using the ROFS API.
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:
• DR4000 system: This consists of preinstalled DR4000 system software on a Dell PowerEdge R510 appliance
platform.
• DR4100 system: This consists of preinstalled DR4000 system software on a Dell PowerEdge R720xd appliance
platform.
The DR Series system consists of a total of 14 drives. Two of these drives are 2.5-inch drives that are configured as a
Redundant Array of Independent Disks (RAID) 1 on the RAID Controller and this is considered to be volume 1. In the
DR4000 system, these drives are internal, while in the DR4100 system, these drives are accessible from the rear. The
data that is being backed up is stored on the 12 virtual disks that reside on the DR Series system appliance. This release
