Revision 1.9 Intel order number E44031-012

4.2.3.1 Availability

The default inactivity timeout is 30 minutes, but may be changed through the embedded web

server.

Media redirection sessions persist across system reset, but not across an AC power loss.

4.2.4 Web Services for Management (WS-MAN)

The Integrated BMC firmware supports the Web Services for Management (WS-MAN)

specification.

4.2.5 Lightweight Directory Authentication Protocol (LDAP)

The Integrated BMC firmware supports the Local Directory Authentication Protocol (LDAP)

protocol for user authentication.

Note: IPMI users/passwords and sessions are not supported over LDAP.

4.2.6 Embedded Webserver

The Integrated BMC provides an embedded web server for out-of-band management. User

authentication is handled by IPMI user names and passwords. Base functionality for the

embedded web server includes:

 Power Control – Limited control based on IPMI user privilege.

 Sensor Reading – Limited access based on IPMI user privilege.

 SEL Reading – Limited access based on IPMI user privilege.

 KVM/Media Redirection – Limited access based on IPMI user privilege. Only available

when the Intel

RMM3 is present.

 IPMI User Management – Limited access based on IPMI user privilege.

The web server is available on all enabled LAN channels.

4.3 Management Engine (ME)

4.3.1 Overview

Intel

Server Platform Services (SPS) is a set of manageability services provided by the

firmware executing on an embedded ARC controller within the IOH. This management

controller is also commonly referred to as the Management Engine (ME).

The functionality

provided by the Intel

SPS firmware is different from Intel

Active Management Technology

(Intel

AMT) provided by the ME on client platforms.

Intel

Server Platform Services are value-add platform management options that enhance the

value of Intel

platforms and their component ingredients (CPUs, chipsets and I/O components).

Each service is designed to function independently wherever possible, or grouped together with

one or more features in flexible combinations to allow OEMs to differentiate platforms.
