HP is racing to the rescue of those threatening to drown in their own data, but that Web 2.0 lot had better be able to hold on until the fourth quarter when HP can deliver what it calls 'Extreme' storage, the NAS-style ExDS9100. It's a 10U BladeSystem that can hold 820TB of SATA-based data and through the wonders of HP's PolyServe clustering can be strung together into a multi-petabyte system - along the lines of what EMC is promising to do with Hulk and Maui widgetry - that can be managed by a single administrator.
