Dual-controller 24-bay SAS array

The HP AW594B P2000 G3 is a 2U rackmount NAS designed for departments and small-to-medium businesses that need shared storage with high availability. It ships as a diskless chassis populated with two P2000 G3 SAS MSA controllers, each providing four 6 Gb/s SAS host ports. The system supports up to 24 small-form-factor drives for consolidated block storage.

24TB raw capacity with 149-drive scaling

The enclosure holds 24 SFF SAS bays and accepts 146 GB or 300 GB 15K SAS drives as well as archival-class SATA drives, delivering a maximum raw capacity of 24 TB inside the chassis. Capacity can grow beyond the initial enclosure by adding expansion units to reach a total of 149 drives, though the 24-bay limit defines the immediate headroom before extra hardware is required.

Replaces single-controller

This dual-controller array upgrades environments running single-controller arrays or direct-attached disks where a controller failure would halt access. The jump is worth it when workloads demand continuous uptime and the ability to mix performance SAS drives with capacity SATA drives in the same pool. It is not suited for buyers who need unified file protocols or more than 24 bays in a single 2U chassis.

Questions about this item

Will the dual SAS controllers in this AW594B work with my existing 6 Gb/s SAS host bus adapters?

Yes, the host interface is SAS 6 Gb/s with four ports per controller, matching your current adapters.

How can I verify both controllers are active after racking the 2U chassis?

Each controller has status LEDs; both should show green when the system posts and the management utility reports dual-controller mode.

The box lists dual SAS controllers and the 24-bay chassis — do I need to purchase drives and rack rails separately?

Yes, the system ships diskless; you must supply up to 24 SFF SAS drives and standard 2U rack rails.
