Byte and Switch: What does TDMF do exactly, and how well is the open systems product selling?
Murphy: It's designed to replicate live, disk-based data from devices on a primary system to disk devices on a secondary system, across any available network connection supporting TCP/IP. Data is duplicated preserving the original write-ordering in near-real time to assure integrity between the two systems in the event of hardware failure, natural disaster, or human error. The replicated data, frozen at a specific point in time, can be made available for reading to applications on the secondary at any point in time by means of a check-pointing mechanism. This allows replicated data to be used for taking backups, doing data analysis or seeding other applications such as Web servers.
About 35 percent of our revenue comes from the TDMF product today; 70 percent of this is on the DAS [direct-attached storage] side and 30 percent is SAN/open systems. But interestingly, with all the Linux announcements from IBM and Sun, my salespeople reckon there could be a renaissance in the mainframe market.
Byte and Switch: OK, data replication's good. But what about storage resource management [SRM], virtualization, policy-based provisioning, disaster recovery, and all that other hot stuff?
Murphy: This is what we've spent the last two years evangelizing about and are now starting to deliver. We've been integrating the various acquisitions we've made, including DataCore Software Corp.'s IP and Vixel Corp.'s [Nasdaq: VIXL] SAN management software, into our SAN management framework.
