HP Insight Recovery Technical White Paper

Overview of
Insight Recovery
1.0
Concepts
Insight Recovery
1.0 is a two
-
site solution based on
the concept of a
primary site
and a
recovery site
.
Insight Recovery
provides a “pus
hbutton” automated DR failover capability
that
is
initiated from the
recovery site
.
Triggering
a DR failover
is
a major dec
ision that
typically req
uires Executive
-
level
approval,
such as
by
a C
IO or other “C
-
Level” Executive
.
In
Insight Recovery
1.0
,
initi
ating
a DR
failover is manual by design, as many factors, both technical and business related, contribute to the
decision to perform a DR failover. Once the decision has been made,
Insight Recovery
automates the
steps associated with performing a DR failov
er.
Example
Configuration
An example of an Insight Recovery configuration is shown in Figure 3 below.
Figure 3:
Insight Recovery example configuration
In Figure 3, configurations at both sites are illustrated (
primary
an
d
recovery site
s). The main
hardware and software components of an Insight Recovery solution are also shown. At each site,
there is a Central Management Server (CMS), which hosts HP SIM and the
Insight Dynamics
--
VSE
software. In addition, the
Insight
Recovery
software runs on the CMS. In addition to the CMS, the
other hardware components include the Storage Management Server (which runs CommandView
EVA), the Proliant Servers (in this example,
c
-
Class
blade enclosure(s)), and the StorageWorks EVA
stora
ge array(s). In
Insight Recovery
1.0, Continuous Access EVA in synchronous mode is used for
storage replication. Therefore, the distance between sites is generally limited to a metropolitan area.
This is due to latency requirements for Continuous Access
EVA synchronous replication. For more
information, refer to the Continuous Access EVA Implementation Guide.
