Deduplication: Flawed Method or Just More Woes for HP?

June 19, 2012

Is HP duping consumers or is SEPATON waging a product war? Its sales versus sales in the article SEPATON: HP Offers ‘Least Capable’ Dedupe in the Industry, with SEPATON full of fire and not pulling any punches. HP did a little dodge and duck, but mainly stayed straight forward.

Linda Mentzer and Peter Quirk from SEPATON stated:

“The HP B6200 offers the least capable de-dupe in the industry. Each tape device on a B6200 is effectively a distinct de-dupe domain. Backups sent to a one drive don’t de-dupe against backups sent to another drive on the same node! What happens when you’re back up exceeds the capability of one drive?”

Beauty is in the eyes of the beholder and apparently HP finds the B6200 much more appealing than its own creator. Sean Kenney from HP Storage challenged SEPATON’s comments, stating:

“It is important to note that the B6200 is a single logical system. Any emulated tape drive within a VTL completely de-duplicates with all other tape drives in that VTL. The B6200 is a terrific solution for database and multiplexed workloads.”

Ah, hardware performance and software issues it seems. HP doesn’t claim the system to be perfect, but instead presents realistic options to prevent issues. Though SEPATON argues that B6200 lacks functionality, they also make it a point to promote their other products. Could this be a coincidence or just more woes for HP?
