8 StoreOnce Catalyst stores
StoreOnce Catalyst technology
HP StoreOnce Catalyst delivers a single, integrated, enterprise-wide deduplication algorithm. It
allows the seamless movement of deduplicated data across the enterprise to other StoreOnce
Catalyst systems without rehydration. This means that the user benefits from:
•
Simplified management of data movement from the backup application: tighter integration
with the backup software to manage file replication centrally across the enterprise from the
backup application GUI.
•
Seamless control across complex environments: supporting a range of flexible configurations
that enable the concurrent movement of data from one site to multiple sites, and the ability to
cascade data around the enterprise (sometimes referred to as multi-hop).
•
Enhanced performance: distributed deduplication processing using StoreOnce Catalyst stores
on the StoreOnce Backup system and on multiple servers can optimize network loading and
appliance throughput.
•
Faster time to backup to meet shrinking backup windows: up to 100 TB/hour* aggregate
throughput, which is up to 4 times faster than backup to a NAS target.
*Actual performance is dependent upon the specific StoreOnce appliance, configuration, data
set type, compression levels, number of data streams, number of devices and number of concurrent
tasks, such as housekeeping or replication. All HP StoreOnce Backup systems can support Catalyst
stores, Virtual Tape libraries and NAS (CIFS/NFS) shares on the same system, which makes them
ideal for customers who have legacy requirements for VTL and NAS but who wish to move to HP
StoreOnce Catalyst technology.
HP StoreOnce Catalyst stores require a separate license on both source and target; VTL/NAS
devices only require licenses if they are replication targets.
Key features
The following are the key points to be aware of with StoreOnce Catalyst:
•
Optional deduplication at the backup server enables greater overall StoreOnce appliance
performance and reduced backup bandwidth requirements. This can be controlled at backup
session/job level.
•
HP StoreOnce Catalyst enables advanced features such as duplication of backups between
appliances in a network-efficient manner under control of the backup application.
•
Catalyst stores can be copied using low-bandwidth links – just like NAS and VTL devices. The
key difference here is that there is no need to set up replication mappings (required with VTL
and NAS); the whole of the Catalyst copy process is controlled by the backup software itself.
•
HP StoreOnce Catalyst enables space occupied by expired backups to be returned for re-use
in an automated manner because of close integration with the backup application
•
HP StoreOnce Catalyst enables asymmetric expiry of data. For example: retain 2 weeks on
the source, 4 weeks on the target device.
•
HP StoreOnce Catalyst store creation can be controlled by the backup application, if required,
from within Data Protector (not available with Symantec products).
•
StoreOnce Catalyst is fully monitored in the Storage Reporting section of the StoreOnce
Management GUI and StoreOnce Catalyst Copy can be monitored on a global basis by using
HP Replication Manager V2.1 or above.
