High uptime requirements aren’t just for banks and hospitals anymore. These days, it’s increasingly common for even smaller companies to find themselves operating in a 24/7 business environment… serving customers all over the world.
That’s why it’s now more important than ever for businesses to ensure they can minimize server downtime without letting IT costs spiral out of control. As you can imagine, this can be a major challenge for both business owners and IT administrators.
High-availability systems can continuously replicate our servers to an alternate emergency failover system. And virtualization technology now gives us the ability to host virtual servers across multiple physical devices for redundancy.
But even if your system hardware is 100% resilient, that still won’t protect you in the event of a network outage.
In order to be completely fault-tolerant, you need to configure your network in such a way that is has no single point of failure.
This might mean implementing redundant network paths, switches, routers and other network elements. Server connections should also be duplicated as a means of eliminating problems caused by failure of a single network component.
It’s also important to make sure you don’t allow network hardware to share common components. For example, multiple systems may suffer an outage if you try to share common hardware across a dual ported network cards. In order to achieve full redundancy, you MUST use a separate piece of hardware for each connection.
When looking into your business continuity strategy, make sure to pay special attention to your network configuration. Even the most robustly protected servers will become useless if the network should ever go down.
