Server and Infrastructure

Arm ServerReady

Arm ServerReady is a compliance program that allows partners to deploy Arm-based servers with confidence.

The program complements the earlier release of the Server Base System Architecture (SBSA) specifications and  Server Base Boot Requirement (SBBR) specifications, alongside Arm’s  Server Architectural Compliance Suite (ACS) v1.6.

Arm ServerReady ensures that Arm-based servers work out-of-the-box, offering seamless interoperability with operating systems and software. Compliant systems that adhere to the Arm ServerReady Terms and Conditions will be issued with a compliance certificate.

Arm Advisory Committee

The Arm ecosystem collaborates on the creation of standards for server through the Arm Advisory Committee. This group contains companies across the server ecosystem including OS, cloud, BIOS, independent software, and IP vendors as well as OEMs and ODMs. The committee communicates in various ways including mail, regular meetings and biannual gatherings.



Server Base System Architecture

Arm architecture covers a wide range of products, across many market segments, from embedded control, to mobile, to servers. Base System Architectures (BSA) provide hardware requirements for a given type of product or market segment. The requirements are intended to ensure standard software, or operating systems, will operate correctly on machines compliant with the BSA.

The Server Base System Architecture (SBSA) is the BSA for servers. The specification is developed in conjunction with partners across the industry:

  • OS vendors
  • Hypervisor, Silicon and BIOS vendors
  • IHVs, OEMs and ODMs.

Server Base Boot Requirements

Operating systems running on standard server hardware require standard firmware interfaces to be present in order to boot and function correctly. The Server Base Board Boot Requirements (SBBR) document describes these firmware requirements.

The SBBR covers UEFI, ACPI and SMBIOS industry standards as well as standards specific to Arm, such as PSCI.

Together with SBSA, the SBBR provides a standard based approach to building Arm servers and their firmware. The specification is developed in conjunctions with partners across the industry:

  • OS vendors
  • Hypervisor, Silicon and BIOS vendors
  • IHVs, OEMs and ODMs.
