Backplane Kit for ST250 V2

This Lenovo kit adds a four-bay 3.5-inch SATA and SAS backplane to a ThinkSystem ST250 V2 server. It is designed for administrators who need to populate the chassis with mechanical hard drives or compatible solid-state drives using standard drive interfaces.

Suits SATA or SAS deployments

The backplane supports both SATA and SAS drives, making it suitable for mixed drive pools in the ST250 V2. Builders whose chassis only accepts a different form factor or who require a bay count other than four cannot use this kit.

Four-bay 3.5-inch capacity

The single specification that determines fit is the four-bay 3.5-inch layout for the ST250 V2. If the server chassis or drive form factor differs, this backplane will not install.

Questions about this item

How much power does the 4-bay 3.5" SATA/SAS backplane draw during continuous operation?

The backplane is a passive drive carrier; it adds no active circuitry, so its own power draw is negligible while the installed drives determine the total load.

Which drive interfaces must the host system provide for this backplane to function?

The kit requires a controller or motherboard with SATA or SAS ports to connect the four 3.5-inch drive bays.

Will this backplane fit in a chassis that currently uses an older Lenovo ST250 drive cage?

The kit is designed for the ST250 V2 3.5-inch bay layout and uses the X30/X40 backplane interface; compatibility with earlier ST250 cages is not guaranteed.
