Forecasting capacity with an eye on performance

Explosive data growth and increasingly complex storage environments make it easy to see the appeal of an automated capacity-planning application. But according to some vendors and analysts, the tools currently available for open systems don't have enough depth to add real value, at least not yet. "A lot of tools are focused just on space usage," says Greg Schulz, senior analyst and founder of The StorageIO Group, Stillwater, MN. To accurately assess your storage needs, you also need to know how much I/O activity applications are generating, he says. And if you don't know how well your volumes are handling activity right now, you might get a skewed picture of your storage needs going forward, says Ted Kicey, product manager for Mainview Storage Resource Manager (SRM) at Houston-based BMC Software. "If I'm running out of space on volumes or in a storage pool, looking at what was there yesterday doesn't help," says Kicey. "I really need to be able to look at real-time data." Mainview SRM is mainframe software that helps optimize ...

Features in this issue

  • Tricky backup for SharePoint

  • CDP: Look before you leap

    Some pundits have postulated that continuous data protection (CDP) will replace backup. But is that just new technology hyperbole or is CDP a must-have technology?

  • Backup-to-disk performance tuning

    Disk-based backup can lower costs, reduce complexity and add scalability. But to achieve top performance, you'll need to do lots of benchmarking and watch for poorly configured production storage.

Columns in this issue

  • Backup best practices are always evolving

    Some new advances in backup, such as virtual tape libraries, represent evolutionary enhancements to the traditional backup process, while others like continuous data protection and single-instance storage are potentially far more transformational.
