Server form factor
The ThinkSystem ST250 server is designed to support both tower and rack form factors.
You can change the server from tower form factor to rack form factor by installing the tower-to-rack
conversion kit. For instructions on how to install the tower-to-rack conversion kit, refer to the documentation
that comes with the conversion kit.
Features
Performance, ease of use, reliability, and expansion capabilities were key considerations in the design of the
server. These design features make it possible for you to customize the system hardware to meet your needs
today and provide flexible expansion capabilities for the future.
Your server implements the following features and technologies:
• Lenovo XClarity Controller (XCC)
The Lenovo XClarity Controller is the common management controller for Lenovo Lenovo ThinkSystem
server hardware. The Lenovo XClarity Controller consolidates multiple management functions in a single
chip on the server system board.
Some of the features that are unique to the Lenovo XClarity Controller are enhanced performance, higher-
resolution remote video, and expanded security options. For additional information about the Lenovo
XClarity Controller, see:

• UEFI-compliant server firmware
Lenovo ThinkSystem firmware is Unified Extensible Firmware Interface (UEFI) compliant. UEFI replaces
BIOS and defines a standard interface between the operating system, platform firmware, and external
devices.
Lenovo ThinkSystem servers are capable of booting UEFI-compliant operating systems, BIOS-based
operating systems, and BIOS-based adapters as well as UEFI-compliant adapters.
• Large system-memory capacity
The server supports error-correcting code (ECC) unbuffered DIMM (UDIMM). For more information about
the specific types and maximum amount of memory, see "Specifications" on page 5.
• Integrated Trusted Platform Module (TPM)
This integrated security chip performs cryptographic functions and stores private and public secure keys.
It provides the hardware support for the Trusted Computing Group (TCG) specification. You can
download the software to support the TCG specification.
Trusted Platform Module (TPM) has two versions - TPM 1.2 and TPM 2.0. You can change the TPM
version from 1.2 to 2.0 and back again.
Note: For customers in Chinese Mainland, TPM is not supported. However, customers in Chinese
Mainland can install a TPM card (sometimes called a daughter card).
• Large data-storage capacity and hot-swap capability
Some server models support a maximum of sixteen 2.5-inch hot-swap drives or a maximum of eight 3.5-
inch hot-swap drives. For some models, you can install up to eight 3.5-inch hot-swap drives and four 2.5-
inch hot-swap drives into the same server.
Some server models support a maximum of eight 3.5-inch simple-swap drives.
