ThinkSystem 2U 24x2.5" SAS/SATA with Rear 4-Bay Expander Backplane

BQ2T is a CTO feature code, not a part number: it is ordered only with the server in a factory (CTO) order, under this code.

Verified in 1 active model(s): Lenovo ThinkSystem SR650 V3

Description

Front SFF drive cage

A front SFF cage with its backplane adds several 2.5-inch hot-plug drive bays to the front of the chassis.

It is used to increase the number of SFF drives in chassis ordered with fewer bays.

Storage capacity and performance increase without external storage.

This text is the general explanation of this category of part (not a claim about one specific model).
