Is Data Domain a VTL?

Data Domain systems simultaneously support data access methods through VTL over Fibre Channel, remote Network Data Management Protocol (NDMP) access over Ethernet for network-attached storage (NAS), Network File System (NFS) and Common Internet File System (CIFS) protocols over Ethernet, and EMC Data Domain Boost.

What is DD VTL?

DD VTL software provides up to 64,000 virtual slots and an unlimited number of virtual tape cartridges, with the ability to dynamically change the number of virtual slots and cartridge access ports.

How does virtual tape library work?

A virtual tape library is an enterprise data storage system that emulates physical tape drives and stores backup data on array-based, RAID-protected disk drives. The virtual tape library works sequentially like tape and writes data to disk in tape format.

How backup is performed using virtual tape library?

A VTL presents a storage component (usually hard disk storage) as tape libraries or tape drives for use with existing backup software. Virtualizing the disk storage as tape allows integration of VTLs with existing backup software and existing backup and recovery processes and policies.

How does Ddboost do deduplication?

As files and data sets are sent over the network, the DD uses RAM and CPU to deduplicate common data, writing only unique data segments to disk. By adding DD Boost, a large part of the deduplication work can take place before the data is sent over the network to the Data Domain.

How do I make a virtual tape library?

Setting up virtual tape storage

1. In IBM Navigator for i, expand Configuration and Service > All Tasks > Tape Devices > Create Virtual Device.
2. Follow the instructions to create a virtual device.

What is IBM virtual tape?

IBM® TS7700 is a mainframe virtual tape solution that optimizes data protection and business continuance for IBM Z® data. TS7770, the latest generation of the family, operates at disk speeds while maintaining compatibility with existing tape operations.

What is VTL and VTS?

VTS eliminates data retrieval latency by storing an instance of frequently used programs in disk caches to provide faster access to the data. VTS also uses a virtual tape library (VTL) built over storage virtualization to reduce the amount of tape disk required.

How much virtual tapes can be their in each tape library?

Each Gateway can manage up to 1,500 virtual tapes or a total of 150 TB of storage in its Virtual Tape Library. Virtual tapes in the Virtual Tape Library can be mounted to a tape drive and become accessible in a matter of seconds.

What does DD Boost do?

By distributing parts of the deduplication process to the backup server, DD Boost speeds up aggregate backup throughput on EMC Data Domain deduplication storage systems by an average of 50 percent, while significantly reducing load on backup LANs and backup servers.

What is DD Boost protocol?

What is Data Domain (DD) Boost? Simply put DD Boost is software that enhances how backup servers and clients interact with a Data Domain backup appliance. It is based on Symantec’s OST (Open Storage Technology) protocol, and is a means to extend Data Domain features back to the source.

Which is used as backup media in virtual tape library?

VTLs are typically used for backup and data archiving purposes. The array of disks is presented to the backup software as tape. Data is written sequentially, just as it would be as if it were being written to rotating tape, but can be written and read more quickly because disk is the underlying media.

Which is data domain system supports VTL access?

Data Domain systems simultaneously support data access methods through VTL over Fibre Channel, remote Network Data Management Protocol (NDMP) access over Ethernet for network-attached storage (NAS), Network File System (NFS) and Common Internet File System (CIFS) protocols over Ethernet, and EMC Data Domain Boost.

How many virtual tape libraries are there in VTL software?

Data Domain VTL software emulates up to 64 virtual tape libraries with up to 540 linear tape-open (LTO)-1, LTO-2, or LTO-3 virtual tape drives. Our VTL software provides up to 64,000 virtual slots and an unlimited number of virtual tape cartridges, with the ability to dynamically change the number of virtual slots and cartridge access ports.

How to configure DD VTL in San Dell Community?

1. Connect all cables. The standard configuration uses a single dual-port FC adapter card in your Data Domain system. Three different speeds (2Gb, 4Gb, and 8Gb) of FC adapter cards are available as well, depending on the Data Domain system, and it is necessary to connect them to the SAN switch.

How many virtual tape libraries can emulate EMC Data Domain software?

However, EMC Data Domain VTL software eliminates tape-related failures by enabling all EMC Data Domain systems to emulate multiple tape devices over a Fibre Channel interface. Data Domain VTL software emulates up to 64 virtual tape libraries with up to 540 linear tape-open (LTO)-1, LTO-2, or LTO-3 virtual tape drives.
