Storage system firmware updates are available as major and minor releases. Companies like EMC Corp. typically provide a major release for its Clariion DRP Firmwarestorage systems about once a year while minor releases come out about once a quarter. Major releases include significant enhancements to storage system features while minor releases provide bug fixes for any issues in the major release. The problems that surface should a company fall behind in its firmware upgrades are increased operational risks as well as delays if fixes are needed.

The need to keep firmware current stems from interoperability problems that emerge when companies change their Fibre Channel SANs. New operating systems, operating system and database upgrades and new Fibre Channel SAN devices constantly introduce new capabilities and features into the SAN. Though storage system vendors typically test for these new features in these products before they are publicly released, companies may need to apply a patch to use them.

Being down two or three major releases also gets problematic. While vendors almost always support older major releases, new patches are based on the last major release. If running an older release, a company may need to wait while a special patch is prepared for them.

Planning firmware upgrades is an easy-to-overlook component of system maintenance. But with many companies in lock-down at this time of year and administrators likely having some free time, December is a good time to plan for and then take the necessary steps to perform a firmware upgrade.
