Mware High Availability
(HA)
provides easy to use, cost |
|
| effective high availability for applications
running in virtual machines. In the event of physical
server failure, affected virtual machines are automatically
restarted on other production servers with spare
capacity. Additionally if there is an OS-related
failure within a virtual machine, the failure is
detected by VMware HA and the affected virtual machine
is restarted on the same physical server. VMware
HAallows IT organizations to: |
|
 |
|
| |
• |
Minimize un-planned downtime and IT
service disruption while eliminating the
need for dedicated stand-by hardware and installation
of additional software. |
| |
|
• |
Provide affordable uniform high availability
across the entire virtualized IT
environment without the cost and complexity of failover
solutions tied to either
operating systems or specific applications. |
|
|
| |
|
|
| |
| Key Features |
• |
Scalable high availability across
multiple physical servers. |
• |
Automatic detection of server failures. |
• |
Automatic restart of virtual machines. |
• |
Improved overall reliability through enhanced
isolation address response. |
• |
Smart failover of virtual machine to servers
withbest available resources |
• |
Proactive monitoring and health checks. |

VERITAS Cluster |
 |
| Veritas Cluster Server is the industry’s
leading clustering solution for reducing both planned
and unplanned downtime. By monitoring the status
of applications and automatically moving them to
another server in the event of a fault, Cluster
Server can dramatically increase the availability
of an application or database. Veritas Cluster Server
can detect faults in an application and all its
dependent components, including the associated database,
operating system, network, and storage resources.
When a failure is detected, Cluster Server gracefully
shuts down the application, restarts it on an available
server, connects it to the appropriate storage device,
and resumes normal operations. Cluster Server can
temporarily move applications to a standby server
when routine maintenance such as upgrades or patches
requires that the primary server be taken offline. |

|
| Key Features |
• |
Comprehensive hardware
and platform support - Using the same
tool across platforms reduces training,
administrative, and hardware costs |
• |
Out-of-the-box support for applications
and databases - Guarantees application
compatibility, reduces time to deployment,
and cuts consulting costs |
• |
Availability across any distance
- Builds both local and remote clusters
for disaster recovery and local availability |
• |
Automated disaster recovery testing
- Tests both failover and replication
configurations without affecting the
primary environment |
• |
Multi-cluster management and reporting
- Manages and reports on multiple local
and remote clusters from a single console |
• |
Simple to install, configure, and
maintain - With wizarddriven installation
and simulated failovers, is easier to
implement and manage than any other
clustering product |
• |
Support for all replication technologies
- Provides flexibility to use any of
the major replication technologies for
disaster recovery |
• |
Advanced failover logic - Ensures
that server resources are utilized as
efficiently as possible by failing over
applications to the most appropriate
server |
• |
Advanced virtual machine support -
Provides clustering support for virtual
machine architectures |
