SFF 2U26 Design
QSAN XF2026D model (2.5” 2U 26-bay) is the industry’s first high-density all flash/low power SAN storage. It has accelerated performance, consolidated space, and two more storage bays (up to 8% more capacity) than the popular 2U 24-bay products available on the market. This can further lower the cost per TB, minimize IT rack space, and generate a smaller and greener footprint.

Dual-Active Design

Dual-Active Design

The XCubeSAN series features a Dual-Active controller architecture. Both controllers concurrently provide storage services in real time. Active-Active architecture doubles the available host bandwidth and cache-hit ratio which ensures there is no wasted resource in the system.

Latest 12Gb SAS 3.0 Controller

Latest 12Gb SAS 3.0 Controller

Fastest 12Gb SAS 3.0
12Gb SAS 3.0 is the latest and fastest drive interface available. It doubles the data transfer rate of SAS 2.0 (6Gb) while remaining backward compatible with 6Gb SAS 2.0 drives. The benefit is that you have the flexibility to purchase less expensive 6Gb SAS drives for initial installation or leverage investment of your existing 6Gb SAS drives and have a peace of mind knowing you can migrate to 12Gb SAS 3.0 by purchasing only new drives.
