Features
Performance, ease of use, reliability, and expansion capabilities were key considerations in the design of the
compute node. 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 compute node implements the following features and technologies:
•
UEFI-compliant server firmware
LenovoLenovo 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.
LenovoLenovo ThinkSystem are capable of booting UEFI-compliant operating systems, BIOS-based
operating systems, and BIOS-based adapters as well as UEFI-compliant adapters.
Note:
The compute node does not support DOS (Disk Operating System).
•
Large system-memory compatibility
The compute node supports 48 connectors of industry-standard double-data-rate 4 DIMM (DDR4),
registered DIMM (RDIMM) or load-reduced DIMM (LRDIMM), 3DS RDIMM, and DC Persistent Memory
Module.
•
Flexible network support
The compute node has connectors on the system board for optional expansion adapters for adding
network communication capabilities to the compute node. You can install up to four I/O expansion
adapters for network support. This provides the flexibility to install expansion adapters that support a
variety of network communication technologies.
