But support for disk was the biggest addition. WysDM isn't first here -- Aptare Inc. added capacity planning for primary storage in August. Perhaps it's no coincidence that WysDM and Aptare are closely aligned with disk vendors. EMC Corp. rebrands WysDM as its Backup Advisor application to monitor tape backups while Hitachi Data Systems (HDS) sells Aptare's StorageConsole as Hitachi HiCommand Backup Services Manager.
Data protection management applications were originally created to monitor tape backups. Vendors include WysDM, Aptare, Bocada Inc., Servergraph, Tek-Tools Inc. and the recently departed Illuminator Inc., which sold its intellectual property to EMC in August. They are driven by cross-correlation relationship engines that take input from all the devices involved in a backup and perform root cause analysis to show which backups are completed. This information is useful in determining which service level agreements (SLA) are in danger of not being met and why. But why limit that functionality to tape backup?
WysDM for Disks provides configuration and status information for disk arrays, helping storage administrators manage utilization metrics, balance logical unit number (LUN) allocations across array ports and ensure fan-out ratios do not exceed vendors' specifications. The product helps administrators perform capacity planning. It recognizes any arrays supported by EMC's Control Center storage resource management (SRM) application at a cost of $7,500 per array.
"Our customers told us lack of visibility on primary arrays was becoming a problem," said WysDM CEO Alan Atkinson. Atkinson is careful not to refer to the product as SRM, perhaps because he doesn't want to be seen as competition for EMC Control Center. "We don't actually make any changes [to the SAN]," he said.
But analysts maintain that data protection and SRM will have more in common as disk becomes more prominent in backups.
"We're headed towards a single console for recovery management, and that software will look at all the tools used, such as virtual tape libraries, continuous data protection and tape," said Arun Taneja of the Taneja Group. "Many data protection management products are morphing and becoming hybrids combining SRM and DPM."
Lauren Whitehouse of the Enterprise Strategy Group said analytical and reporting tools for disk and tape are valuable for determining if storage SLAs are being met.
"End users crave more visibility into their storage and data protection environments," she said. "We're seeing service level agreements negotiated between IT organizations and their business constituents. For many organizations, what is lacking is the ability to demonstrate if SLAs are being met. This will not only provide visibility into operations, but will provide a measurement of recovery performance."
