MDB Deployment › Planning for Availability

Planning for Availability

The data stored in the MDB is critical and is required for the operation of CA solutions that manage your IT infrastructure. It is important that you plan for availability in case of any eventuality that would put your IT infrastructure and the functionality of critical business processes at risk. Without such planning, the MDB could become a single point of failure. You may use several features of the underlying relational database management software to help protect against failures. These include the use of failover capabilities, cluster support, custom replication, and the performance of database backups on a regular basis.

Planning for availability must be an integral part of the implementation of your CA solutions.

Hardware

A planned and designed Management Database (MDB) environment provides a quality, high performing system with extendable growth capability. Lack of or incorrect architecture decisions may cause poor performance, lack of scalability, poor reliability, or poor availability. To prevent such problems, the following key areas should be considered prior to MDB deployment:

• Processor Technology (in database servers a minimum of two is preferred)
• Storage and I/O subsystems (in database servers a minimum of two I/O channels is recommended)
• Network Bandwidth and Availability (in database servers utilize backbone networks for linking servers to each other, where possible separate out client to server traffic from server to server traffic)
• Dedicated or shared server MDB deployment
