Overview

The Dell™ Chassis Management Controller (CMC) is a hot-pluggable

systems management hardware and software solution designed to provide

remote management capabilities and power control functions for Dell

PowerEdge™ M1000e chassis systems.

You can configure the CMC to send e-mail alerts or SNMP trap alerts for

warnings or errors related to temperatures, hardware misconfigurations,

power outages, and fan speeds.

The CMC, which has its own microprocessor and memory, is powered by the

modular chassis into which it is plugged.

To get started with the CMC, see "Installing and Setting Up the CMC."

What’s New For This Release

This release of CMC supports the following features:

• IPv6 — CMC now supports the IPv6 protocol.

The IPv6 Ready Logo Committee's mission is to define the test

specifications for IPv6 conformance and interoperability testing, to

provide access to self-test tools, and to deliver the IPv6 Ready Logo.

CMC and iDRAC are Phase-2 IPv6 Ready Logo certified, and the Logo ID

is 02-C-000378 (Dell PowerEdge M1000e). For information on the IPv6

Ready Logo Program, see

www.ipv6ready.org

.

• VLAN tagging — The CMC and the iDRACs now support the ability to

assign their network traffic to a virtual LAN (VLAN).

• Single sign-on for active directory accounts — Single sign-on allows users

authenticated using Microsoft

®

Active Directory

®

on their local systems

to automatically apply those credentials to the CMC Web user interface.

18 Overview

• Two-Factor Authentication using Smart Card — Provides added

security — a smart card plus a PIN to authenticate a user instead of

just a password.

• Public Key Authentication (PKA) over SSH — Improves SSH scripting

automation by removing the need to embed or prompt for

user ID/password.

• Power management enhancements — Flexible power supply redundant

modes: 1+1, 2+1, and 3+1. Additional fault-tolerant AC redundant

modes: 1+1, 2+2, and 3+3.

• Additional error reporting options — The iDRAC system events log is

displayed on the

Blade Status

page eliminating the need to log into the

iDRAC to view them. Also, CMC events are now also posted to a remote

syslog server.

• Remote Virtual Media File Share option — to map a file from a share drive

on the network to one or more blades through the CMC, to deploy or

update an operating system.

• Ability to read and clear SEL entries for servers from the CMC.

CMC Management Features

The CMC provides the following management features:

• Redundant CMC Environment

• Dynamic Domain Name System (DDNS) registration for IPv4 and IPv6

• Remote system management and monitoring using SNMP, a Web

interface, iKVM, or Telnet or SSH connection

• Support for Microsoft

®

Active Directory

®

authentication — Centralizes

CMC user IDs and passwords in Active Directory using the Standard

Schema or an Extended Schema

• Monitoring — Provides access to system information and status of

components

• Access to system event logs — Provides access to the hardware log and

CMC log

Overview 19

• Firmware updates for various components - CMC, servers, iKVM,

and I/O module infrastructure devices

• Dell OpenManage™ software integration — Enables you to launch

the CMC Web interface from Dell OpenManage Server Administrator

or IT Assistant

• CMC alert — Alerts you to potential managed node issues through an

e-mail message or SNMP trap

• Remote power management — Provides remote power management

functions, such as shutdown and reset on any chassis component, from a

management console

•Power usage reporting

• Secure Sockets Layer (SSL) encryption — Provides secure remote system

management through the Web interface

• Password-level security management — Prevents unauthorized access to a

remote system

• Role-based authority — Provides assignable permissions for different

systems management tasks

• Launch point for the Integrated Dell Remote Access Controller (iDRAC)

Web interface

• Support for WS-Management

•

FlexAddress

™

feature - Replaces the factory-assigned World Wide

Name/Media Access Control (WWN/MAC) IDs with chassis-assigned

WWN/MAC IDs for a particular slot; an optional upgrade (for more

information, see "

Using FlexAddress"

)

• Graphical display of chassis component status and health

• Support for single and multi-slot servers

• Update multiple iDRAC management consoles firmware at once

• LCD iDRAC configuration wizard supports iDRAC network configuration

• iDRAC single sign-on

20 Overview

• Network time protocol (NTP) support

• Enhanced server summary, power reporting, and power control pages

• Forced CMC failover, and virtual "reseat" of servers

Security Features

The CMC provides the following security features:

• User authentication through Active Directory (optional),

or hardware-stored user IDs and passwords

• Role-based authority, which enables an administrator to configure specific

privileges for each user

• User ID and password configuration through the Web interface

• Web interface supports 128-bit SSL 3.0 encryption and 40-bit SSL 3.0

encryption (for countries where 128-bit is not acceptable)

NOTE: Telnet does not support SSL encryption.

• Configurable IP ports (where applicable)

• Login failure limits per IP address, with login blocking from the IP address

when the limit is exceeded

• Configurable session auto time out, and number of simultaneous sessions

• Limited IP address range for clients connecting to the CMC

• Secure Shell (SSH), which uses an encrypted layer for higher security

• Single Sign-on, Two-Factor Authentication, and Public Key

Authentication
