Embargoes are getting ever more stupid these days, wasting analysts’ and bloggers’ time in doomed attempts to micromanage the news flow. ParAccel is no exception to the rule. An announcement that’s actually been public knowledge for a couple of months was finally made official a few minutes ago. It’s an appliance, or at least an attempt to gain customers for an appliance. The core ideas include:
- ParAccel’s usual shared-nothing configuration is hooked up to SAN-based EMC storage at the back end.
- Around half of the total data is on internal (i.e., node-specific) disks, mirrored on the storage device. The rest of the data lives only on the EMC device. Logically, all this data is integrated. So hopefully you’ll be able to process more data per unit of time than you could on a standard ParAccel configuration.
- Also, different parts of the EMC device are dedicated to different ParAccel nodes. So, while this isn’t a shared-nothing architecture, at least it’s shared-not-very-much. (DATAllegro does something similar, although without the mirroring on direct-attached storage.)
- Backup, snapshotting, and so on are inherited from EMC. Administration will increasingly be integrated with EMC’s.
