The purchase of Persist is about Information Lifecycle Management, compliance with data retention regulations, and Persist’s grid-like storage array.

Persist was founded last year, and emerged from stealth only this summer with front-end archiving software and a grid-style back-end disk array.

HP’s focus in the acquisition was the back-end, based around multiple HP server blades and ATA disks, which Persist claims is far more scalable, reliable and simpler to use for high-volume storage than conventional disk arrays.

The deal contradicts the ILM strategy that HP declared last month, when it said it would be partnering with a range of third-party suppliers.

HP said it would continue to resell Persist’s front-end archiving software, which it admitted would compete with software sold by some of the third parties that HP named as ILM partners.

It had already dropped hints to those companies about the purchase, and was very confident that they will be happy to integrate their front-end software with the Persist back-end.
