Chaparral VFS113 About Serverless Backup, Note:

Introduction

Industry-leading data transfer (MB/sec) and transaction processing rates (IOPS)

Automatic SCSI device discovery and SCSI-to-FC address mapping

Retention of SCSI-to-FC addressing during device removal/addition and between power cycles

Support for Persistent Reserve In and Persistent Reserve Out commands

Support for Report LUNs command

Firmware upgrades via RS-232

Warnings and automatic shutdown for out-of-specification temperature and voltages

Embedded Configuration Application Programming Interface (CAPI) for management and Graphical User Interface (GUI) development

Extended Copy command available for serverless backup

The router is available in both low-voltage differential/single-ended (LVD/SE) and high- voltage differential (HVD) SCSI models.

Note: It is important to know which model you have and the associated features. (See Specifications below.)

About Serverless Backup

Recent advances in data protection architectures have added the ability to back up data by moving it directly from disk to tape without first passing through a backup server. This is called serverless backup, and it utilizes a new SCSI command, Extended Copy (EC). A host is involved in executing the EC command, though it is typically not the server. The Chaparral family of Intelligent Storage Routers is enabled to execute the EC command under the control of most major backup applications.

The EC command consists of three primary pieces of information:

Source addresses

Destination address

In-line data

The source addresses tell the router where the data that is being copied is physically stored, on what device and at what physical locations. This information is provided by a backup application, which must translate file information into the physical storage locations. The application sends this list of addresses in the order it is to be written to the destination device, often a tape drive in a backup scenario.

For the destination address, the EC command assumes that any tape device that is being copied to is in the proper location, so all the router needs to know is its target address, typically a LUN on the SAN. The in-line data is used to allow applications to maintain a specific format, and can be used to write any data the application may require for restoration.
