The SKU: 94R4K (also listed as 094R4K)  is a Dell part number for a specialized 3.5-inch LFF (Large Form Factor) Hard Drive Tray/Caddy.

Unlike standard Dell PowerEdge server caddies, this part belongs to the DSS (Datacenter Scalable Solutions) line, which is built for massive data centers and cloud service providers.

They are used to house 3.5-inch SAS or SATA hard drives and solid-state drives in the following systems:

• ::Dell DSS 7000: An ultra-dense 4U storage server that can hold up to 90 hard drives. The 94R4K is the specific bracket that slides each of those 90 drives into the chassis.
• ::Dell DSS 7500: A server node often used within the DSS 7000 ecosystem.

This option (94R4K) is not compatible with standard Dell PowerEdge servers (like the R730, R740, or R750). Those use the "G13" or "G14" style caddies, which have a completely different latching mechanism and physical shape.

Why are these specific trays important?

In a server like the DSS 7000, which can store over a petabyte of data in a single rack unit, these trays serve several critical functions:

• ::High-Density Thermal Management: The tray is designed to allow specific airflow patterns required when 90 drives are packed tightly together.
• ::Hot-Swapping: It allows administrators to pull out a failing drive and click in a new one without shutting down the entire server.
• ::Vibration Dampening: Because 90 spinning hard drives create significant vibration (which can cause data errors), these trays are engineered to keep the drive stable and secure.
