Why Tape Virtualisation?


Why Companies look at VTLs Tape Drive

Backup Job

 Backup jobs not
completing?
 Tape drive utilisation low?
 Tape drive quality
problems?
 Aggressive recovery time
objectives (RTO)?
 High operating costs of
nearline infrastructure?

… But Tape is Still Important © by Sophie Graf

 Best economy of scale
 Best medium for long term archiving
 Most energy efficient way of storing data
 Less error prone than disk

 52% of disk & tape users plan to increase
tape usage*
 13% decrease of disk only systems in 2007*
 58% of disk only users plan to start using
tape*

Integrating the best of both worlds

How CentricStor addresses both worlds

Focus Backup Application on Core
Competence Policy Driven Mgmt of Storage
Location
 No need to actively manage the Backup Appl.
storage location of a saveset  Long term / less access on
CentricStor tape
 Offload media mgmt tasks to
CentricStor  Demanding RTO on disk
LD LD
 Short term data on disk only
 Critical data on mirrored disk /
multiple tape copies
LV LV

Improve Quality of Tape Operation logical
 No stressful start/stop operation physical
 Automatic tape reorganisation PD PD

 Automatic tape refreshing PV PV
 Dual / Triple Save / Vaulting
Physical Library
 Seamless migration to new tape

Support future growth and standards:
No limits – unmatched scalability

CentricStor Grid Architecture
 The “centric” storage for data protection
 Modular building blocks
 Designed for
unlimited disk cache
 Performance

 actual models with
> 2 PB capacity (compressed)
 1.500.000 Virtual Volumes

 Scalability in all dimensions
 Frontend
- Virtual tape drives
- Throughput
 Backend
- Physical tape drives
- Backup capacity


Business continuity:
Protected data needs to be replicated

CentricStor Grid Architecture Redundant data protection
 Building blocks spread across  Active-active disk cache mirroring
different physical locations
 Immediate recovery after a site outage
 Long distance connections
 Automated triple save for tape:
 Automatic failover against site outages - two local copies against media errors
 Unmatched disaster resilience - third copy at the vault location


Seamless change to future technology:
Some data has to be stored for years

True Tape Virtualization Without server drawback
 Always the newest tape technology  Seamless swap
 Technology change by CentricStor VT  Maintain only one current standard
 Easy doubling physical library capacity  Always the most economic footprint


Support different retention policies:
ILM with disk and tape

CentricStor VT - the only “Dual Target”
virtual tape solution on the market
 Optional choice of
 D2D2T / long term
 D2D / short term
lifetime of your backup

Economic use of disk
 Compression of tape data
before entering disk
Tape encryption
 Protection against loss of data
 Seamless plug-in integration
 Best of breed encryption appliances


The most energy efficient technology:
Green Storage – CentricStor VT

The most advanced integration of tape
 Not all data needs to be stored on disk
 Resource usage appropriate
to the value of data
 Tape is still the most energy
efficient way to store data
 Managed tape storage needs less
power than comparable disk solutions

Consolidation reduces
 Total cost of backup storage
 Footprint for backup and archiving
 Power consumption
 Data center air conditioning
