Ensuring Business Continuity for Virtualization

Virtualization is a growing trend in the IT industry. Organizations are leveraging
virtualization in distributed environments to reduce their overall physical server footprint
and maximize the utilization of

each physical server. Reducing the number of physical
servers decreases the carbon emissions and power consumption by the organization. This
is the right thing to do for the environment and can reduce the organization’s power and
support costs.

Virtualization
Virtualization Example

However, introducing virtualization increases the complexity of ensuring critical
applications, such as company email or front
-
end applications are always available.
Having data recoverability with robust and proven solutions is als
o essential to all virtual
solutions.

Virtualization Over Time

CA, Inc. (CA) provides software to address business continuity for virtualization. The
following sections identify two CA software products that address high availability and
disaster r
ecovery for distributed virtual environments.

High Availability

One of the most important factors for putting critical applications in virtual environments
is ensuring high availability. It is important to understand that the virtual environment
provides
high availability at a physical server level. CA’s VMware Distributed Resource
Scheduler (DRS) addresses global scheduling by creating dynamic resource pools of
physical machines. DRS can then dynamically move entire virtual machines across the
pool with
out having to restart the virtual machines themselves. When a physical machine
runs out of resources or becomes unavailable the DRS will automatically move the
virtual machines to another available physical server. This ensures high availability at a
sys
tem level, but not at an application level.


In order to truly ensure high availability for applications in virtual environments,
CA
XOsoft™ High Availability (HA) is needed. This software provides high availability at
the application level. Combining this CA software with VMware HA provides a
complete high availability solution for your virtual environments. This industry leading

software provides data replication, automated push
-
button or fully automated failover and
fail
-
back of the application server over a LAN or WAN, application aware status
monitoring, integrated TRUE Continuous Data Protection as a guard against data
corrup
tion, and completely non
-
disruptive automatic testing of your disaster recovery
system. CA’s software sets the industry standard for ease of configuration and
management.

High Availability

If you implement both CA and VMware high availability

solutions both the master and
replica virtual machines are safely implemented on the same physical servers as
identified in the following diagram. Through virtualization the overall cost of high
availability is reduced because you no longer need to acqui
re additional hardware to
implement the solution. This increases the viability of the solution for all applications.

Software Highlights



Failover functions as expected but once the primary system is back up, the two
systems
can be resynchronized by restarting the High Availability scenario. The
application can then fail
-
back with a push of a button. This eliminates the need
for time consuming and complex reconfiguration to prepare for the fail
-
back.



TRUE Continuous Data Pro
tection (CDP) is supported to recover the data back to
any point in time. This allows rewind capability to before the interruption due to
data corruption (if this is the cause of disruption). This reduces downtime and
data loss.



Automated testing with As
sured Recovery. Regular or scheduled testing of the
solution can be performed using Assured Recovery.. Manual testing is also
supported.

CA XOsoft™ High Availability provides coverage for the following applications:





Microsoft Exchange



Microsoft SQL Se
rver



Oracle



Microsoft IIS Web Servers



Blackberry Server



File Servers



Other applications on both 32

Backup and Recovery

All server environments need some level of backups done. Virtual servers require
integrated backup solut
ions in order to restore data to a specific application on a virtual
machine. CA ARCserve® Backup (ARCserve) provides an integrated backup solution
for VMware Consolidated Backup (VCB) support. This integration allows ARCserve to
backup your virtual envi
ronments, as well as your physical servers.

The ARCserve integration with VMware provides a special agent for virtualization. This
agent supports the physical to virtual bare metal restore, as well as file level restores to
support disaster recovery for your virtual environments. File level restores to the original
virtual machine location is also supported for virtual environments.


ARCserve provides the following agents in addition to the VMware Agent:



Microsoft SQL Server



Microsoft Exchange Server



Microsoft SharePoint



Oracle



Lotus Domino



SAP R/3



Sybase



Many others

These ARCserve agents ensure data integrity by protecting the transaction log, archive
log, journal files, and the data itself. The agents provide high

Finally, ARCserve is integrated with the
CA XOsoft™ High Availability. This
integration allows the user to browse and backup replicated data, restore data to the
master or replica server, create synthetic full backups, view CA XOsoft Replication
Reports, and launch the CA XOsoft Replication inte
rface. This integration provides a
