Software
Application Integrated Snapshots
The StoreVirtual Application Aware Snapshot Manager allows for the creation of application
consistent snapshots of VMware and Hyper-V VMs and of Microsoft VSS enabled applications.
Application Integrated snapshots create instant point-in-time copies of data on a per-volume basis.
Snapshots can be created in a variety of ways to meet business or application requirements.
Administrators can create them manually ad-hoc, on a scheduled or scripted basis, or via the
Microsoft VSS framework, and can then access these point-in-time snapshots to recover individual
files or folders from the volume, or rollback an entire volume. Unlike most storage vendors that
require a snapshot reservation, StoreVirtual Snapshots are always thinly provisioned for efficiency,
only consuming storage space on the array for the data written to the snapshot, eliminating any
upfront space reservation or guesswork that could lead to snapshot and backup job failures.
Built into the StoreVirtual storage and Centralized Management Console, application integrated
snapshots provide automated quiescing for Microsoft VSS enabled applications without additional
software or hardware requirements. Sets of VSS snapshots are easily created, scheduled, and
recovered using the CMC.
Remote Copy
StoreVirtual Remote Copy lets customers replicate thin provisioned snapshots between primary and
remote locations. Because remote copies are thin provisioned no space reservation at the remote
location is required. Remote Copy is used for centralized backup and disaster recovery and can be
set up on a per-volume basis. Remote copies placed on a recurring schedule allow customers to
achieve point-in-time asynchronous replication of the data between locations, sites, or data
centers.
Integrated into the StoreVirtual Remote Copy software is intelligent bandwidth management
ensuring that the data traffic can be sent across shared WAN links without adversely impacting
other network traffic. Administrators simply set the bandwidth limit for remote copies between the
two sites and the LeftHand OS software holds that limit.
A failover/failback wizard is also included with Remote Copy for step-by-step, easy to execute
disaster recovery procedures when needed most.
Remote-Copy leverages application integrated snapshots to enable VMware and Hyper-V VMs as
well as Microsoft VSS applications to be replicated in a quiesced state, providing faster application
recovery.
Adaptive Optimization (VSA and 4335 only)
HP StoreVirtual Adaptive Optimization is an innovative technology that greatly increases the
efficient use of faster storage devices (such as SSDs or Storage Accelerators) by intelligently
moving data between storage devices with different performance characteristics within a single
storage system.
The StoreVirtual Adaptive Optimization feature reduces planning complexity by utilizing innovative
algorithms to pinpoint hot data at a highly granular level and re-provision data in real time while
maintaining a balance between background IO operations and application IO requirements. The
result is an effective solution that increases performance substantially without administrator
intervention.
Adaptive Optimization is configurable on a per volume basis, and requires no tuning or specialized
configuration to implement.
Performance benefits are available immediately, as the StoreVirtual Adaptive Optimization engine
constantly monitors the IO demands placed on the StoreVirtual cluster and reacts in near real-time.
There is no need to wait for a scheduled operation to move data to the proper tier.
