Introduction

Corporate IT departments face tough challenges in providing large scale PC

management. These challenges can become increasingly costly in terms of time,

manpower, and budget. The widespread physical location of systems, system power

state or a non-functional operating system can lead to inaccurate or even

impossible management.

Management technologies are now available to ease client management with

platform resident hardware and firmware solutions. HP offers the following

solutions:

ASF

AMT

DASH

AMT and DASH give corporate IT departments the means to remotely manage

multiple clients in an Out-Of-Band (OOB) environment. OOB manageability allows

PC control and configuration regardless of the system power state or presence of an

operating system.

OOB manageability only requires that a platform be connected to a network and

to a power source. Note: An OOB managed system must be connected to a power

source but does not have to be turned on. AC power from a wall socket or DC

power from a battery are both acceptable.

ASF

Alert Standard Format (ASF) was the computer industry’s initial attempt to

standardize out-of-band management capabilities. Introduced in 2001, ASF is an

older standard with limited functionality and industry support.

The goals of ASF are to provide the following:

Advanced warning and system failure indication from managed clients to

remote consoles.

OS-absent functionality such as a presence heartbeat.

OS-absent remote control capability such as remote power and boot control.

Ensure interoperability between vendors of alerting and corrective-action

devices.

Intel AMT

Intel Active Management Technology (AMT) is an Intel initiative to provide OOB

manageability for desktop PCs and notebooks. AMT was introduced in 2006 and

has continual development from Intel.

The goals of Intel AMT are to provide the following:

OOB access with built-in manageability in the chipset.

Asset management for tracking and inventory.

Remote remediation services with redirection and remote control.

Proactive management services with alerts, event logging and reporting.

Intel AMT is available on systems with Intel vPro Technology

DASH

DASH (Desktop and mobile Architecture for System Hardware) is an initiative to

define protocols and processes for over-the-wire management of desktops,

workstations, laptops, and converged devices.

DASH is defined by the Distributed Management Task Force (DMTF), an industry

organization leading the development of management standards. A number of

companies provided input into the creation of the specification including:

Hewlett-Packard

Intel

AMD

Broadcom

DASH is an alternative to Intel AMT and shares many of the same features and

goals as Intel AMT. However, Intel AMT is proprietary to Intel and can only be used

with high-end Intel desktop and mobile chipsets, whereas DASH is compatible with

any chipset providing certain requirements are met.

Intel AMT v3.2 and later contain DASH support although the level of support is

dependent on the Intel AMT version.

Use Case –Asset Management

Asset management is the ability to remotely manage many systems with a single

console to detect and track PCs and their components.

Management technologies use hardware and software inventory capabilities that

are available at all times to give an accurate response.

Corporate Systems

Management Console

1. IT polls clients for HW

assets.

2. Clients respond with HW

information regardless of

power state or OS

availability.

3. Results in accurate HW

asset management

throughout the corporation.

Use Case –Remote Remediation Services

Remote remediation is the ability to remotely diagnose and solve system

malfunctions to reduce downtime and productivity loss.

Management technologies use media and text redirection along with remote power

and booting to correct problems.

BSOD System

Fixed System

1) User calls for help with BSOD

2) IT takes control of the managed

system and reboots it.

Bootable Diagnostic Image

4) IT remotely diagnose and correct problem.

3) Redirect system to IT diagnostic

image

Use Case –Proactive Management Services

Proactive management is the ability to generate alerts on pre-determined events

and log them for later analysis.

Management technologies use event-based alerting along with event logging and

reporting to aid IT departments in detecting failing systems and correcting the

problem before an actual failure occurs.

IT Department

Figure 3: Proactive Management

1) Hard drive fails SMART and the event is logged

No alert is sent to IT because system is

not on the network.

2) IT reads event log to determine if an event occurred

while the system was offline

3) IT sees the SMART failure event.

4) IT sends personnel to backup data and replaces HDD

before HDD crash occurs.

Later, the network is restored.
