Frequently Asked Questions - 4U60 WESTERN DIGITAL

What is the maximum capacity of the WD 4U60?

The 4U60 supports up to 60 drives. With current 22TB HDDs, total capacity can exceed 1.3 PB raw. With SSDs, capacity varies.

Is the 4U60 compatible with any RAID controller?

It works with standard SAS controllers like LSI/Broadcom 9300/9400 series and HPE Smart Array. Check your controller’s expander support.

How do I install drives in the 4U60?

Slide the drive sled into an empty bay until it clicks. Use hot-swap procedures: do not touch circuitry, and wait for indicator to stabilize.

What type of drives does the 4U60 support?

It supports 3.5-inch and 2.5-inch SAS or SATA drives, both HDD and SSD. Use enterprise-grade drives for best reliability.

How do I manage the 4U60 enclosure?

Access via the web interface using the default IP (see manual) or use CLI via SSH. View health, fan speeds, temperature, and drive status.

Can the 4U60 be cascaded with other enclosures?

Yes, using the SAS expansion ports. You can daisy-chain multiple enclosures to a single controller, up to 240 drives (4 enclosures).

What is the power consumption of the 4U60?

Idle consumption is around 200W with few drives. Full load with 60 HDDs can exceed 1200W. Use redundant 2000W PSUs to handle peaks.

How do I replace a failed power supply?

Press the latch and pull the PSU out while the other remains live. Insert the new unit until it clicks. No tools required.

What are the cooling requirements?

Ensure front and rear airflow clearance (at least 6 inches). The enclosure uses front-to-back cooling. Ambient temperature should be 10-35°C.

Does the 4U60 come with drive sleds?

It includes 60 empty drive sleds. If you need spare sleds, order part number WD-SLED-4U60.
