High Availability Solutions

• Is your organization equipped to deal with business interruptions, potential data loss, and significant reconfiguration efforts every time you encounter a minor system failure?
• Did you know that the steps you take to protect your business from major disasters are probably not the best ways to protect your systems from routine failures?
• Do you wonder if all of your systems need to be highly available?

InfoSight will help you answer these questions by surveying and analyzing your current infrastructure and helping you develop a detailed business case based on your specific needs, because in a volatile and technology-dependent business climate, just one hour of unplanned downtime could cost your organization hundreds of thousands of dollars.

Industries such as the financial services and health sector have a requirement to protect the data they store. This requirement can involve the availability of the data. In other industries, such as healthcare and the military for example, the systems must be highly available to meet safety requirements.

Organizations, whose systems must be available at all times, need to ensure efficient protection of critical data and applications across virtually any set of circumstances. Optimal protection from day-to-day disruptions and catastrophic events comes from combining high availability solutions - that prevent disruptions and ensure immediate and seamless recovery from the majority of failures - with conventional disaster recovery solutions that provide remote application and data backup.

High Availability vs. Disaster Recovery
High availability and disaster recovery are often thought of as being the same thing. Although they are related, they are separate topics; however, the technologies are converging. High availability can best be summed up as "keeping the lights on," while disaster recovery is the process and procedures for recovering the critical infrastructure after a natural or man-made disaster in the shortest possible time.

High availability is not, and can never be, a substitute for a well-planned backup regimen. Backup is your ultimate "get out of jail card." When all else fails, you can always restore from backup, an essential part of your disaster recovery planning.

While enterprises need to be prepared for "the big one," the reality is that systems usually go down as the result of far less dramatic events, like network failures, disk crashes, or power, fire or telecommunications outages. High availability will ensure efficient protection of critical data and applications across virtually any set of circumstances.

As you face mounting pressure to keep your systems running 24x7 and provide continuous access to data, applications and transactions, look to InfoSight to help you protect against day-to-day disruptions and outages.

What is
High Availability?

High Availability (HA) can be defined in a number of ways, depending on the business goal. For simplicity sake, we'll define high availability as the "clustering" of multiple servers in a single location, which is usually the case. These servers are logically joined together to maximize the availability of the critical services and applications provided by that system. Each server in the cluster has redundant hardware components managed by software that provides fault detection and correction procedures. Should one server fail, another server in the cluster takes over automatically, i.e. it doesn't require manual, human intervention to identify a failed component, execute a procedure to avert a system failure, and notice the averted failure. As a result, the systems exhibit almost no downtime; they provide service 99.999% of the time. In the case of high availability across a single site, a disaster recovery solution must be implemented separately for obvious reasons.
