1 Matrix recovery management Overview
Matrix recovery management is a component of the HP Matrix Operating Environment that provides
disaster recovery protection for logical servers and for
Matrix infrastructure orchestration services
Logical servers and Matrix infrastructure orchestration services (
) that are included in a
Matrix recovery management configuration are referred to as
logical servers and IO
services. A DR Protected
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
. When a
DR Protected logical server is running on a virtual machine under the control of a hypervisor, it is
referred to as a
. DR Protected IO services can run on VM hosted logical
servers only.
A Matrix recovery management configuration consists of two sites, each managed by the HP Matrix
Operating Environment. The site where the Central Management Server (CMS) you are logged
into is located is referred to as the
, and the other site in the Matrix recovery management
configuration is referred to as the
. Matrix recovery management pairs symmetrically
configured logical servers or IO services across the two sites. One logical server or IO service in
the pair is activated at one site, while the other (peer logical server or IO service) is deactivated
at the other site. The boot images of these DR Protected logical servers and IO services, including
applications code and data, reside on disk array volumes. The source volumes at the site where
one of the logical servers or IO services in the pair is activated are replicated at the other site
where its peer logical server or IO service is deactivated. These volumes are part of a
that uses storage array supported replication. One or more logical servers or
IO services can be associated with a single Storage Replication Group – this is referred to as a
.
In a Matrix recovery management configuration each Recovery Group has a
where
you prefer it to be activated, and a
where you prefer it to be deactivated. A
Recovery Group 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
—see
. Recovery Group Sets can be selected for activation or deactivation at the Local Site.
Recovery Group Sets can be failed over from one site to the other site in a Matrix recovery
management configuration. For example, if a disaster occurs at the Local Site, the administrator
at the Remote site can trigger a failover for all of the Recovery Groups that were activated at the
Local Site by activating them at the Remote site. This prepares the storage associated with the
deactivated DR Protected logical servers and IO services at the Remote site for read-write access,
and activates those logical servers and IO services.
