Direct from the Press Announcement:
Achieving a 1TB/s sustained bandwidth with existing state-of-the-art storage technologies requires close to 55,440 disk drives, 396 SAN controllers, 792 I/O servers and 132 racks of equipment.
Fusion-io can achieve this same bandwidth with 220 ioDrive Octal cards, housed in Infiniband-attached I/O servers running the Lustre parallel file system. This 1TB/s Fusion-io based solution requires only six racks, or less than 1/20th the rack space of an equivalent, high-performance, hard disk drive-based storage system.
I’ll discuss what this means in a future post.
