Neverfail Heartbeat
Powers Neverfail’s wide range of affordable “cluster-class” application
availability and disaster recovery solutions for the Microsoft technology
platform
Now that the costs of computing power and network solutions have become
affordable for most small and medium-sized business, companies have become
highly dependent upon them for their productivity and profitability. Today, no
business can afford downtime. But until Neverfail, most companies couldn’t
afford the high availability solutions designed to keep their systems up and
running.
The heart of Neverfail: Neverfail Heartbeat
Neverfail Heartbeat is the core technology that powers all of Neverfail’s
application availability and disaster recovery solutions for the Microsoft
technology platform. Neverfail Heartbeat’s “cluster-class” solution replicates
data from an active server to a passive server in either a LAN or WAN
environment to protect Microsoft applications against a wide range of potential
failures.
In severe cases, should the active server fail, the passive server can assume
the full identity of the active server and take over all processing. Neverfail
Heartbeat’s switch-over feature is an automatic, seamless process to ensure
continuous application availability and is completely invisible to the end
user.
High availability over a LAN or WAN environment
Neverfail Heartbeat can be configured to protect your email in either a LAN or
WAN environment. Where bandwidth or network utilization is an issue or needs to
be reduced, the Neverfail Low Bandwidth Module (LBM) is available to optimize
and reduce the amount of data that is transmitted between the two servers.

Neverfail Heartbeat— a first in high availability solutions
Back-up and replication offerings focus only on recovering hardware and data
failures from a primary server. Most clustering solutions only address certain
type of failures. Neverfail Heartbeat is the first “cluster-class” high
availability solution to focus on the entire application environment, including
data, the operating system, the server, the network and each and every
application to ensure no single point of failure.
In addition to offering highly available, “out of the box” application
protection solutions for Microsoft® Exchange, SQL and File Server, Neverfail
protects auxiliary applications such as anti-virus, back-up, fax, and archiving
via our Application Module eXtension - AM(X) - technology. Neverfail supplies
an application program interface to quickly and easily generate these
extensions. Neverfail’s existing library of AM(X)s is extensive, fully
maintained and supported to assist you in avoiding the added costs of “one off”
development practices on your critical server.
Key Features
| Data protection |
-
Neverfail uses Asynchronous replication between servers and only replicates
data changes to increase efficiency.
-
Protects data with minimal impact to live production performance.
|
| Seamless switch- over, fail-over and switch-back |
-
Compared to “one way street” replication solutions, Heartbeat’s architecture
allows movement of workload seamlessly back and forth between systems.
-
Provides higher availability with minimal disruption to users during and after
a switch- or fail-over. Saves time associated with recovering from an outage.
|
| Integrated LAN/WAN support |
-
Neverfail delivers a single integrated product designed to support both LAN and
WAN environments.
-
Saves time and resources by eliminating the need to learn and manage multiple
products and “add-ons” associated with a LAN- or WAN-specific component.
|
| “Shared Nothing” architecture |
-
Does not require the primary and secondary servers to share any resources.
-
Saves money by not requiring the purchase of high priced storage configurations
to protect the single point of failure created by traditional clustering
solutions using shared disk.
|
| Hardware agnostic |
-
Applying an operating system patch or security update often requires rebooting
the server. Neverfail enables you to apply maintenance updates without
re-booting the active server.
-
Saves time and money by avoiding outages and downtime associated with
maintenance of a production server.
|
| Non-disruptive server upgrades |
-
Neverfail Heartbeat’s unique architecture allows you to switch to a completely
new production server with no changes or modifications to the operational
environment.
-
Saves time and reduces the risks associated with upgrading server hardware.
|
| Network connectivity monitoring |
-
Monitors the active server’s public network availability. Automatically
initiates a fail-over if the server cannot access the public network.
-
Improves availability by monitoring production server network connectivity.
|
Reliability is the first step to achieving high availability
The successful implementation and ongoing performance of any cluster-class high
availability solution is predicated upon a reliable technology platform.
Neverfail’s Server Check Optimization Performance Evaluation (SCOPE) is the
only automated software solution to deliver a comprehensive health “check-up”
of your server environment. SCOPE identifies existing configuration and
performance issues in your environment prior to installation of a high
availability solution and it provides “snapshots” of your environment to ensure
on-going reliability.
Neverfail Heartbeat Summary
Your business is dependent upon every aspect of your IT solution — from the
network, all the way down to every application you’re running. Failures in any
one component can lead to downtime, lost productivity and profitability. Why
settle for a partial solution when Neverfail Heartbeat can deliver
comprehensive, proactive failure protection for all elements of your server
environment? With Heartbeat at the core of every easy to install and easy to
afford high availability Neverfail solution, you can count on maximum uptime.
