Mass Parallelism

Each logical volume in the Nextra system is divided into multiple stripes of one megabyte. These stripes are spread over all the disks in the system, using a sophisticated pseudo-random distribution mechanism.

Nextra's revolutionary approach ensures that:

• All disks and modules are used equally, regardless of access patterns. Nextra keeps the load perfectly balanced, even if certain applications access certain volumes, or certain parts within a volume, more frequently.
• The pseudo-random distribution ensures consistent load-balancing, even after volumes are added, deleted or resized, or hardware is added or removed.
