Evaluating HA and DR solutions

It's more important than ever to be cautious when making a large IT investment because what may seem like the right purchase today (based on initial cost) can potentially turn into a financial burden tomorrow if you don't do your homework. You need to ask the tough questions when evaluating mobile messaging HA and DR solutions. When evaluating a HA and DR for BlackBerry solution, it's important to run through the following checklist and ask yourself these ten questions. Will the solution:

1. Offer both a manual and automatic failover/failback by the click of a single button? Look for solutions that will automatically detect a BES outage and provide seamless failover and service restoration for all users within 90 seconds. When every minute of downtime represents potential lost revenue, you want your service to be back up and running without a glitch-and before anyone notices.

2. Not impose architectural constraints or force system rebuilds? For example, a HA solution allowing both the BES and database to be deployed on the same server or separate servers gives maximum flexibility and cost options.

3. Offer protection for the associated configuration database? This ensures complete functional availability, including for security-related tasks such as remote device management.

4. Provide HA and remote WAN deployment for DR to protect from complete site failure? You shouldn't have to choose between local HA and remote DR. Look for flexible solutions that offer both LAN and WAN support and provide the most comprehensive protection available.

5. Offer complete data protection through data replication, ensuring both the data and the registry can be rolled back and BES logs recovered? Data protection through replication ensures that the primary and secondary servers are identical and complete environment protection preserves the log files-which is important from a compliance perspective.
