HP Matrix Operating Environment 7.0 Recovery Management User Guide

1 Overview
Matrix recovery management is a component of the HP Matrix Operating Environment. Matrix
recovery management provides disaster recovery protection for logical servers configured and
managed by HP Matrix OE visualization. Logical servers that are included in a Matrix recovery
management configuration are referred to as DR Protected logical servers. A DR protected logical
server can run on a physical machine (C-class blade), or on a virtual machine hosted by a
hypervisor. When a DR protected logical server is running on a C-class Blade equipped with HP
Virtual Connect, it is referred to as a VC hosted logical server. When a DR protected logical server
is running on a virtual machine under the control of a hypervisor, it is referred to as a VM hosted
logical server.
A Matrix recovery management configuration consists of two sites, each managed by the HP Matrix
Operating Environment. At any point in time, the site where the Central Management Server (CMS)
you are logged into is located is referred to as the Local Site, and the other site in the Matrix
recovery management configuration is referred to as the Remote Site. Matrix recovery management
pairs symmetrically configured logical servers across the two sites. One logical server in the pair
will be activated at one site, while the other (peer logical server) will be deactivated at the other
site. The boot images of these DR Protected logical servers, including applications code and data,
reside on disk array volumes. These volumes are part of a Storage Replication Group that uses
storage array supported replication. The source volumes at the site where one of the logical servers
in the pair is activated are replicated at the other site where its peer logical server is deactivated.
In a Matrix recovery management configuration, a Recovery Group consists of one or more logical
servers that are associated with a single Storage Replication Group. Each Recovery Group has a
Preferred Site and a Secondary Site, but can only be activated on one site at any time. A set of
Recovery Groups that share the same Preferred and Secondary Sites is referred to as a Recovery
Group set. Recovery Group sets can be selected for activation or deactivation at the Local Site.
Recovery Group sets are activated at one site and deactivated at the other site in a Matrix recovery
management configuration. If a disaster occurs at the site where a Recovery Group Set is activated,
the administrator at the other site in the Matrix recovery management configuration can trigger a
failover by activating the deactivated peer Recovery Group Set. This action will prepare the storage
associated with the deactivated DR Protected logical servers for read-write access, and then activate
those logical servers.
Some benefits of Matrix recovery management 7.0
• Provides an automated failover mechanism for up to 500 DR protected logical servers and
associated storage managed by the HP Matrix Operating Environment.
• Extends the HP Matrix Operating Environment value of a common management interface to
the realm of disaster recovery, for logical servers running on physical or virtual machines.
• Supports hypervisor hosted virtual machines.
• Supports standalone HyperV.
• Supports Microsoft Windows Server 2008 with HyperV R2 in a clustered configuration with
cluster shared volumes (CSV).
• Supports flexible cross-technology logical servers - VC hosted logical servers can fail over to
become VM hosted logical servers, and VM hosted logical servers can fail over to VC hosts.
• Supports multiple logical servers in a Recovery Group.
• Supports Bi-Directional failover of Recovery Group sets between two sites, allowing both
activated and deactivated Recovery Groups to exist at the same site.
• Supports HP P6000 Continuous Access Software (formerly known as HP StorageWorks
Continuous Access EVA) storage replication in synchronous and asynchronous mode.
