The HP StoreOnce B6200s are designed to deliver a resilient solution to provide enterprise wide data
protection. Scale-out capacity and performance to keep pace with shrinking backup windows, reliable
disaster recovery, simplified protection of remote offices and rapid file restore to meet today's SLAs.
Customers can start out by purchasing one HP StoreOnce B6200 48TB system consisting of two nodes
connected in failover configuration as a couplet. This is delivered pre-integrated into HP extended depth
42U racks which also contains the necessary networking capabilities for future expansion within the entire
rack using an HP StoreOnce B6200 switch assembly.
To scale-out in terms of capacity, simply add up to 3 capacity upgrade kits to each couplet. Each upgrade
kit comprises 2 shelves which are added symmetrically, both sides of the couplet. Each shelf contains 12x
1TB or 2TB disks, giving 24TB or 48TB raw capacity (16- 32TB usable), allowing up to a maximum of 192TB
raw capacity (128TB usable) associated with the original node.
Capacity upgrade kits can be added to the couplet while the Backup System is online in order to reduce
unnecessary downtime.
A fully configured couplet with 3 capacity upgrade kits, can be managed as a single file system of up to
192TB raw capacity (128TB usable), however to optimize performance within a couplet, capacity usage
should be balanced across both nodes within a couplet.
To scale-out in terms of performance, add in one more HP StoreOnce B6200 48TB system and again scale
up by adding capacity upgrade kits. This gives you a maximum configuration of two fully configured HP
StoreOnce B6200 48TB system of two couplets with a total capacity of 384TB raw capacity (256TB usable)
in a single rack.

deduplication
- extend data retention
on disk
Data deduplication is a method of reducing storage needs by eliminating redundant data so that over time
only one unique instance of the data is actually retained on disk. As a result, typically 20x more backup
data can be retained in the same disk footprint.
Adding data deduplication to disk-based backup delivers a number of benefits:
HP StoreOnce B6200 Backup
A cost effective way of keeping your backup data on disk for a number of weeks or even months.
More efficient use of disk space effectively reduces the cost-per-gigabyte of storage and the need
to purchase more disk capacity.
Making file restores fast and easy from multiple available recovery points. By extending data
retention periods on disk, your backup data is more accessible for longer periods of time, before
archiving to tape. In this way, lost or corrupt files can be quickly and easily restored from backups
taken over a longer time span.
Ultimately, data deduplication makes the replication of backup data over lower bandwidth WAN
links financially viable (providing offsite protection for backup data) as only changed data is sent
across the connection to a second device (either a second identical device or one that comes from
this product family).
HP StoreOnce deduplication
HP StoreOnce deduplication software simplifies the deployment of deduplication technology across IT
infrastructures. With explosive data growth driving IT sprawl, deduplication technology is quickly
becoming a requirement for many customers to help reduce the capacity required to store information.
Traditional deduplication technologies tend to approach the problem from a fragmented
perspective and this results in multiple deduplication methodologies being deployed adding to the
management complexity of the infrastructure. HP StoreOnce is different; as a next generation
deduplication architecture, it is not sold as standalone software, but rather is a portable engine that
can be consistently embedded in multiple products, eliminating the complexity of first generation
deduplication. HP StoreOnce uses patented innovation and features designed by HP Labs to
maximize backup and restore performance while minimizing management and hardware overhead.
How it works
Deduplication works by examining the data stream as it arrives at the storage appliance, checking for
blocks of data that are identical and eliminating redundant copies. If duplicate data is found, a pointer is
established to the original set of data as opposed to actually storing the duplicate blocks, removing or
"deduplicating" the redundant blocks from the volume. The key here is that the data deduplication is being
done at the block level to remove far more redundant data than deduplication done at the file level where
only duplicate files are removed.
Data deduplication is especially powerful when it is applied to backup, since most backup data sets have a
great deal of redundancy. The amount of redundancy will depend on the type of data being backed up, the
backup methodology and the length of time the data is retained.
Example. Backing up a large customer database that gets updated with new orders throughout the day.
With the typical backup application you would normally have to back up, and store the entire database.
Even incremental backups will result in storing the full database to disk once again, taking up increasing
amounts of disk space with almost identical backup data sets. With block-level deduplication, you can

Features and Benefits
backup the same database to the device on two successive nights and, due to its ability to identify
redundant blocks, only the blocks that have changed will be stored. All the redundant data will have
pointers established.

infrastructures. With explosive data growth driving IT sprawl, deduplication technology is quickly
becoming a requirement for many customers to help reduce the capacity required to store information.

What deduplication ratio can I expect?
The actual data deduplication ratio you can expect will depend on a number of factors including: the type
of data, the backup methodology used, and the length of time you retain your data. However, assuming
standard business data mix and extended on disk retention (periods of more than 12 weeks) you could
expect to see 20:1 deduplication ratio assuming a weekly full and daily incremental backup model
Is there likely to be any impact on performance?
The actual performance achieved using an HP StoreOnce B6200 is dependent upon a number of factors
including data set type, compression levels, number of data streams, number of devices emulated and
number of concurrent tasks, such as backup and deduplication, housekeeping, and replication. In general,
the more process steps, the longer it may take. Consequently, when compared to backup without
deduplication, a reduced amount of data will be backed up AND replicated within the same timeframe.
For help with choosing the most appropriate HP StoreOnce B6000 configuration for your specific
environment, we recommend you talk to your HP partner or sales advisor about using the HP storage

Data
replication network efficient
disaster recovery
Data replication is the process of making a duplicate copy of a data set across a network to a "target site".
It is generally used to transmit backup data sets off-site to provide disaster recovery (DR) protection in the
event of catastrophic data loss at the "source site"
Replicating large volumes of data backup over a typical WAN is expensive. However, today's products with
data deduplication have made it possible to replicate data over lower bandwidth links for a more costeffective, network efficient replication solution that provides a practical disaster recovery solution and an
ideal solution for centralizing the backup of remote offices.
Data deduplication shrinks the amount of backup data that needs to be replicated from the source HP
appliance, and as a result significantly reduces replication bandwidth requirements. Once a replica of the
data backup set has been created on a remote HP target appliance all that is required to keep the replica
identical to the source is the automatic, periodic copying and movement of the new data segments which
are created during each backup. With such small amounts of data being transmitted asynchronously,
lower bandwidth networks offer sufficient performance and a much lower cost solution.
NOTE:
D2D and HP StoreOnce B6200, but not VLS.
HP StoreOnce B6200 Backup
Replication of data can only occur between devices within the same product family ie. HP StoreOnce
HP StoreOnce Catalyst seamless data movement
across the enterprise
HP's data replication feature includes replication bandwidth limiting functionality, restricting the amount
of bandwidth being used when replicating data for even more network-efficient replication. Without
replication bandwidth limiting, a replication job could use as much bandwidth as is available, potentially
making other network activities unresponsive. Replication bandwidth limiting is customer configurable at
the appliance level via the graphical user interface and is set as a percentage of the available network
bandwidth.
HP delivers replication by license, either as a standalone replication solution, or as part of the HP
StoreOnce Catalyst licensing (see the following section below). For the HP StoreOnce B6200, a total of 96
source appliances can replicate to a single HP StoreOnce B6200 48TB target, this increases to 384 when 4
couplets are used. Once licensing has been applied, configuring and using replication is made
straightforward by the graphical user interface and configuration wizard on the HP appliance.
Replication licensing requirements grow as you system grows. Licensing is per target backup system, so
you won't add to the cost no matter how many remote offices you need to replicate to a single HP
StoreOnce B6200 Backup. Each couplet being used as a replication target within the backup system
requires a replication license.
See the 'Related Options - Replication licenses' section of these QuickSpecs for more details.
HP StoreOnce Catalyst brings the HP StoreOnce vision of a single, integrated enterprise-wide
deduplication algorithm a step closer. It allows the seamless movement of deduplicated data across the
enterprise to other StoreOnce Catalyst systems without rehydration. This means that you can benefit
from:
Simplified management of data movement from a single pane of glass: tighter integration with your
backup application to centrally manage file replication across the enterprise.
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).
