Neverfail for SQL Server
The most comprehensive high availability, low cost software solution for
Microsoft SQL Server.
From the Rolodex to the PDA, the filing cabinet to the database server, the
drive in business has always been to store, access and share data more
efficiently and cost effectively. Once an innovation, the database and
management of its data is now a business necessity. How much would it cost your
company in lost productivity, sales and revenue to go a day without Microsoft®
SQL Server? With Neverfail for SQL Server, you’ll never have to know.
The heart and soul of Neverfail for SQL Server – Neverfail Heartbeat
The most important consideration in protecting your Microsoft SQL Server
environment is creating a real-time, duplicate copy of your SQL data. Neverfail
Heartbeat sits at the core of Neverfail’s suite of affordable, “cluster-class”
solutions, replicating data from your active to your passive server, whether
they reside in the same server room, or across the globe.
Neverfail for SQL Server is the only high availability solution that proactively
monitors your entire SQL environment
With new databases being created, data being appended, changed, deleted and
more, SQL Server environments never stand still— they’re subject to constant
change. Neverfail for SQL Server proactively monitors your SQL Server
application, including all system and data tables, looking for just such
changes. It then reconfigures itself accordingly to ensure any and all changes
are included in its replication set.
In addition to monitoring the SQL application, Neverfail for SQL Server is the
only cluster-class, high availability solution to proactively monitor the
health of your entire SQL environment, including: physical server hardware,
network infrastructure and operating system. If any problem occurs, Neverfail
can take a variety of preemptive, corrective actions without resorting to a
full system fail-over. In extreme cases, a graceful switch-over to your
secondary server can occur automatically, ensuring continuous SQL availability.
Neverfail can also protect auxiliary applications that you may have installed
onto your server. These may include supporting applications such as anti-virus,
backup and archiving solutions. Our Application Module eXtension - AM(X) -
technology provides an application program interface to easily and rapidly
generate these extension products.
High availability over a LAN or WAN environment
Neverfail for SQL Server 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.
You’ll only find switch-back capabilities in Neverfail for SQL Server
In addition to offering both manual and automatic switch-over capabilities,
Neverfail for SQL Server also features the ability to seamlessly switch-back,
something replication solutions can’t offer. Whether your primary server is
down for several hours or even days, Neverfail will seamlessly resynchronize
your servers when the primary does come back online, and allow you to switch
your workload back to a normal production state within a few minutes by the
simple click of a button!
Reliability is the first and most crucial 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.
