NetApp - Major acquisitions

1 2005 - Alacritus: The tape virtualization technology Alacritus brought to NetApp was integrated into the NetApp NearStore Virtual Tape Library (VTL) product line,

introduced in 2006.


NetApp - Filers

1 In 2006, NetApp launched a Virtual Tape Library (VTL) product for magnetic tape data storage

virtualization.


iSCSI - Targets

1 The underlying implementation can deviate drastically from the

presented target as is done with virtual tape library (VTL) products


High-performance computing - Software tools and message passing

1 The parallel architectures of supercomputers often dictate the use of

special programming techniques to exploit their speed. Software tools for distributed processing include standard Application

programming interface|APIs such as Message Passing Interface|MPI and Parallel Virtual Machine|PVM, Virtual tape library|

VTL, and open source-based software solutions such as Beowulf (computing)|

Data deduplication - Source versus target deduplication

1 * Target deduplication is the process of removing duplicates of data in the secondary store. Generally this will

be a backup store such as a data repository or a virtual tape library.


Data deduplication - Major players and technologies

1 * CA's ARCServe and XOsoft, SIR, FDS (Virtual Tape Library, Single Instance

Repository, and File Deduplication System)


FalconStor - Products

1 FalconStor's Software includes Virtual Tape Library (Virtual tape library|VTL)

with data deduplication, Continuous Data Protector (Continuous Data Protection|CDP), File-interface Data deduplication|

Deduplication System (FDS) and Network Storage Server (NSS), each enabled with

Wide area network|WAN-optimized replication for disaster recovery and

remote office protection


Cofio Software - ViStor

1 ViStor is a software implementation of a Virtual Tape Library (VTL). It was

released in 2007 to OEM's in Asia specifically who create VTL

appliances using the ViStor software. Software runs on a version of Linux and supports the iSCSI protocol as

well supporting Emulex Fibre Channel Host Bus Adapters. This product was

EOL after the HDS acquisition.https://store.theartofservice.com/the-virtual-tape-library-toolkit.html

Data Domain (corporation) - History

1 Unlike most of its early competition, it was first packaged as a file-system

appliance; this made it more predictable than a software product

and simpler to manage than a virtual tape library system.


Virtual Tape Library

1 A 'virtual tape library' ('VTL') is a computer storage|data storage

Storage virtualization|virtualization technology used typically for backup

and recovery purposes. A VTL presents a storage component

(usually hard disk storage) as tape library|tape libraries or tape drives

for use with existing backup software.


Virtual Tape Library

1 While a virtual tape library is very fast, the disk storage within is not designed to be removable, and does not usually involve

physically removable external disk drives to be used for data archiving in place of tape. Since the disk storage is always connected

to power and data sources and is never physically electrically isolated, it is vulnerable to potential damage and

corruption due to nearby building or power grid lightning strikes.


IBM Tivoli Storage Manager - Product details

1 Actual user data is managed via a cascading hierarchy of storage media (Primary Storage

Pools) presented as raw devices (UNIX), filesystem containers (Windows and Linux),

streaming tape or optical media. Additionally, emulated tape from a Virtual tape library|Virtual Tape Library or EMC Corporation|EMC Centera

WORM archival device are supported. Duplicate copies (Backupsets or Copy Storage Pools) of

any subset of data may be created on sequential media for redundancy or off-site

management.


IBM Storage - Virtual tape libraries

1 * TS7620 ProtecTIER Deduplication Appliance - Preconfigured repository that can be configured with either a

Virtual Tape Library or Symantec OpenStorage interface with a

capacity of up to 35 TB.


IBM Storage - Virtual tape libraries

1 * IBM Virtualization Engine TS7700 series - The TS7700 is a virtual tape

library for System z (mainframe) that uses disk drives for cache to accelerate backup operations


Seven tiers of disaster recovery - Tier 3: Electronic vaulting

1 The facilities for providing Electronic Remote Vaulting consists of high-

speed communication circuits, some form of channel extension equipment and either physical or a virtual tape

library and an automated tape library at the remote site


Glossary of backup terms - Terms and definitions

1 ; virtual Tape Library (VTL) : a storage device that appears to be a tape library to backup software, but actually stores data by some other

means. A VTL can be configured as a temporary storage location before data is actually sent to real tapes or it can be the final storage location

itself.


Disk staging

1 The process of disk staging is controlled by the same software that

performs actual backups, which is different from virtual tape library where intermediate disk usage is

hidden from main backup software. Both techniques are known as D2D2T

(disk-to-disk-to-tape).


Network Appliance, Inc. - Major acquisitions

1 * 2005 - 'Alacritus': The magnetic tape data storage|tape virtualization

technology Alacritus brought to NetApp was integrated into the NetApp NearStore Virtual Tape

Library (VTL) product line, introduced in 2006.
