Virtual Tape Library Solutions by Hitachi Data Systems
VTF Open—a Virtual Tape Library
Solution for open systems
VTF™ Mainframe—a Virtual Tape
Library Solution for mainframe systems
ProtecTIER™ VT—a Virtual Tape
Library Solution for open systems featuring HyperFactor™
advanced data de-duplication technology for capacity
optimization Virtual Tape Library Solutions by Hitachi Data Systems enable storage managers to obtain all the benefits of backing up to disk without changing established backup policies or procedures. The integrated suite of the software, server, and disk creates a "virtual" tape library that appears to the backup application as one or more real tape libraries.
Replacing slow tapes with high-speed disk,
enables customers to increase backup/recovery performance,
optimize their storage infrastructure, and achieve their business
resilience objectives. Virtual Tape Library Solutions delivers
streamlined backup and recovery operations, greatly improved
recovery point objectives (RPOs) and recovery time objectives
(RTOs) objectives, along with significantly reduced total cost of ownership (TCO).
VTF Open
VTF™ Open is a scalable enterprise-class software solution that emulates tape libraries without changing the practices, policies or procedures of your backup application.
VTF Mainframe
VTF™ Mainframe is a scalable mainframe-class software solution that emulates tape libraries without changing the practices, policies or procedures of your backup application.
ProtecTIER VT
ProtecTIER™ is an enterprise-class data protection platform that, when combined with its HyperFactor™ deduplicating technology, reduces the required backup disk capacity by up to 25x without disruption to your backup infrastructure.
- ProtecTIER™ is an enterprise-class data protection platform that, when combined with its HyperFactor™ deduplicating technology, reduces the required backup disk capacity by up to 25x without disruption to your backup infrastructure.
- Shortens the backup window.
- Consolidates heterogeneous tapes and helps you gain control of your decentralized open systems data.
- Simplifies data management.
- Utilizes remote disk for disaster recovery enabling rapid data restore with a high degree of integrity while significantly reducing manpower costs.
- Significantly reduces storage total cost of ownership (TCO).
"We've studied tape processing extensively and we're here to say that tape isn't going away, but it can be improved and that's exactly what Diligent and Hitachi Data Systems have done...improved tape processing."

6 Reasons the HDS VTL is a better than Data Domain |
Reason #1 - Performance
Data Domain
HDS ProtecTIER
Reason #2 - Scalability
Data Domain
-
Data Domain VTL Appliance
-
Data Domain’s largest appliance, DD580, provides 15 TB of
useable disk
-
When this capacity is exhausted, companies must purchase
another appliance
HDS ProtecTIER
Reason #3 - Guaranteed better data deduplication factoring
ratio
Data Domain
-
If multiple appliances are required, each will be its own
“compression domain”
-
Data on one box cannot be shared with other boxes providing
lower overall de-dupe capability
HDS ProtecTIER
-
Uses variable block sizes to maximize factoring
-
Not sensitive to insertions, deletions, name changes
Reason #4 - Guaranteed not to have data corruption issues
Data Domain
Hash Based
-
Creates a fingerprint (Hash) for each chunkette of data
-
De-duplicates when the same fingerprint is computed on new
data
-
Does not compare stored data to new data
-
Possibility of unique data being discarded resulting in data
corruption
HDS ProtecTIER
Reason #5 - Guaranteed to require less management resources
Data Domain’s small boxes result
in appliance
sprawl
-
DD’s largest appliance, the 580, has only 15TBs of useable
disk
-
Many companies end up with multiple DD appliances as the
amount of data they are backing up grows
HDS ProtecTIER with Hitachi
storage is
expandable
-
Capacity can be increased without adding additional servers
-
One ProtecTIER server provides performance equivalent to
three or four Data Domain appliances
-
Multiple ProtecTIER servers can be managed from a single
console
Reason #6 – Limited VTL Support and Experience
Data Domain’s VTL
Appliance
-
Only announced VTL interface in Q1 2006 (3 years after
Diligent)
-
No success stories with customers using VTL interface
-
Limited to only 47 LTO virtual tape drives
HDS ProtecTIER
-
Extensive virtual tape experience since 2003
-
One ProtecTIER server can emulate 16 tape libraries, 256
drives and 8192 tape cartridges
