Overview

The HP OpenView Storage Mirroring Advanced Service 1 LTU is a software license activating HP's continuous block-level volume replication platform for a single protected server. Where scheduled backup tools create periodic snapshots — leaving a data exposure window proportional to the backup interval — Storage Mirroring operates by capturing and transmitting changed disk blocks to a target volume in near-real time. For a single protected server, this means the target mirror is never more than seconds behind the source under normal operating conditions, and RPO in a failure scenario is measured in seconds rather than hours. The Advanced Service tier extends the base mirroring capability with application-aware failover logic, allowing the platform to manage failover in a manner that accounts for application state consistency, and adds WAN replication controls including bandwidth throttling — critical for sites replicating across limited inter-site links.

This license is positioned for IT environments where a small number of critical servers — file servers, database hosts, transaction processing nodes — require a recovery capability that backup software architecturally cannot provide. The single-LTU model means procurement is targeted: one license per protected server, deployed where the business consequence of a multi-hour recovery from backup tapes is unacceptable. HP OpenView Storage Mirroring runs at the OS volume level, meaning it is not tied to specific HP storage hardware — it operates across Windows Server environments regardless of whether the underlying storage is HP, Dell, or commodity. Organizations evaluating this platform today should prioritize a compatibility check against their current Windows Server versions and HP's current support lifecycle documentation, as this is a mature platform with a defined product history.

Frequently Asked Questions

This Advanced Service LTU (License to Use) activates HP OpenView Storage Mirroring's continuous block-level replication capabilities — synchronizing a source volume to a target volume in real or near-real time. Unlike scheduled backup snapshots, Storage Mirroring maintains a live mirror, dramatically reducing the recovery point objective (RPO) when a storage failure occurs.
The Advanced Service tier adds capabilities beyond basic volume mirroring — typically including application-aware failover, bandwidth throttling controls for WAN replication scenarios, and more granular failover/failback automation. The base license covers fundamental disk mirroring; Advanced Service extends this to protecting specific application data streams and managing the replication relationship over lower-bandwidth links.
This is a perpetual License to Use covering a single protected server instance. In HP OpenView's licensing model, one LTU entitles you to mirror one source server's storage to a target. Organizations protecting multiple servers require one LTU per protected source node.
HP OpenView Storage Mirroring operates at the OS and volume level rather than requiring specific HP storage hardware — it can mirror volumes between Windows servers regardless of the underlying storage array. However, the HP OpenView management framework and appropriate Windows Server OS versions are prerequisites; check HP's compatibility matrix for your specific server OS version before deploying.
Traditional backup software creates point-in-time snapshots on a schedule, meaning data written between backup windows is at risk. Storage Mirroring continuously replicates changed blocks to the target, eliminating that exposure window. For applications requiring sub-minute RPOs — financial databases, transaction systems, critical file servers — this is the architectural gap backup software cannot fill.
