Monitoring and configuration tools
Continuity Software Inc.'s RecoverGuard continually checks to determine that all changes made to the primary site are reflected on the backup site; identifies dependencies among servers, storage devices, databases and apps; and automatically detects gaps such as the passive node on a cluster not being mapped to the correct disk volume, which could cause a problem during a DR event.
RecoverGuard (which Continuity Software plans to offer as a service) currently supports EMC Corp. and NetApp arrays, with support for Hitachi Data Systems hardware expected in the next few months.
WysDM Software Inc.'s WysDM for Backups continually monitors back-up environments and provides customized policy-based alerts about problems that could affect the DR environment.
| (EMC recently acquired WysDM Software.) Among other conditions, it can report on servers that haven't been backed up within a given period of time, and backups that need to be rescheduled to meet service-level agreements.
BladeLogic's Data Center Automation suite can monitor the configuration of backup data centers to see if they vary from corporate policies. Vick Viren Vaishnavi, BladeLogic's director of product marketing, says some customers are using the suite to help them synchronize changes among sites.
Tracking such changes is much easier when a firm maintains the same hardware and software at both the primary and DR site, and uses virtualization to mask any disparities between the two. Dick Cosby, systems administrator at Estes Express Lines, used system utilities for his firm's IBM System Storage DS8000 storage to mirror changes in data, as well as changes to the sizes of the underlying volumes and LUNs, between the Richmond, VA-based headquarters and a DR facility in Mesa, AZ. But Cosby says he wouldn't be able to rely on this integrated process if, for example, he introduced EMC storage into the environment.
