Access Control 34

Log in with Single Sign-on (SSO)

SSO uses centralized authentication servers that other applications and systems utilize for authentication purposes, and combines this with techniques to ensure that users do not actively have to enter their credentials more than once.

Kerberos SSO requires specific domain environment settings for the Windows Active Directory (AD) domain controller, Power Center server, and Web b row s er.

Single Domain Environment

The following illustration shows how to set up a single domain environment with the following components:

• Domain Controller — dns.dcm.dell.com is the Windows AD server that supports domain dcm.dell.com (Father and Child).

• Power Center Server Center installed.

• Power Center Client connects to the Power Center server.

—

server1.dcm.dell.com is the server with Power

—

server2.dcm.dell.com is the client server that

To set up the Kerberos SSO single domain environment, perform the following steps:

Step 1. Install Power Center

When installing Power Center:

Set up a Realm Name. You must enter a Fully Qualified Domain Name (FQDN) of the Realm. For example, dcm.dell.com.

Access Control 35

Set up AD domain controller addresses. Separate multiple addresses with a comma. For example, 192.168.0.250.

Specify a domain user for dcm.dell.com as Power Center server’s domain account for Kerberos SSO. This user account must be an existing and valid domain user account. For example, "Tom" and Tom’s password.

Step 2. Set up Service Principle Name (SPN) for Power Center service in AD Domain Controller

Log into the AD domain controller as an Administrator.

Open a command console.

Add two SPNs for Power Center, use server FQDN in one SPN and server NetBIOS name for the other SPN. The user account associated with service SPN must be the Power Center server’s domain account for Kerberos SSO configured during Power Center installation or in the

Settings

page. For example:

setspn -a HTTP/server1.dcm.dell.com Tom

setspn -a HTTP/server1 Tom

Step 3. Configure Web browser

You must configure your Web browser to support SSO. For more information on how to configure this, see your Web browser Help. For a list of supported Web browsers, see "System Requirements" in the "Overview" chapter.

NOTE: To correctly set up Kerberos SSO: 1) The date and time on all involved

computers must be consistent. 2) DNS configuration must be correct.

To support SSO in Firefox, you must send Kerberos credentials to the appropriate KDC.

To support SSO in Internet Explorer, you must add the Power Center server as a local Intranet site.

The following is an example of configuration steps in Microsoft Internet Explorer 8:

Go to

Internet Explorer 8 → Internet Options → Security → Local

Intranet,

Click

and click

Advanced

Sites

. The Local Intranet window opens.

, add your Power Center site into Local Intranet. For

example, server1.dcm.dell.com.

Access Control 36

Multiple Domain Environment

The following illustration shows how to set up a multiple domain environment with the following components:

• Domain Controller — There are several Windows AD domain controllers in the illustration, including the parent domain dcm.dell.com and the child domans east.dcm.dell.com and west.dcm.dell.com.

• Power Center Server

—

server1.east.dcm.dell.com is the server with Power Center installed. It is an AD domain controller, the domain name is east.dcm.dell.com

。

• Power Center Client — test.west.dcm.dell.com is the client server that connects to the network of the Power Center server.

To set up the Kerberos SSO multiple domain environment, perform the following steps:

Step 1. Install Power Center

When installing Power Center, do the following:

Set up the Default Realm Name of the domain in which Power Center is installed. You must enter FQDN. For example, east.dcm.dell.com.

Set up the AD Domain Controller addresses. Separate multiple addresses with a comma. For example, 192.168.0.2, 192.168.0.3.

Specify a domain user for east.dcm.dell.com as Power Center server’s domain account for Kerberos SSO. For example, "Jerry" and Jerry’s password.

Step 2. Set up SPN for Power Center service

Access Control 37

Set up SPN for Power Center service in all involved AD domain controllers. In the example, three domains are involved: dcm.dell.com, east.dcm.dell.com and west.dcm.dell.com. Repeat the following steps on each domain.

Log into the AD domain controller as an Administrator.

Open a command console.

Add two SPNs for Power Center:

• If it is on the Default Realm (configured in Step 1), the user account

associated with the service SPN must be the Power Center server’s domain account for Kerberos SSO configured in Step 1. For example,

setspn -a HTTP/server1.east.dcm.dell.com Jerry

setspn -a HTTP/server1 Jerry

• If it is not on the Default Realm, for example, it is on dcm.dell.com,

the user account associated with the service SPN must be a domain user account in the current domain. For example, Jack is a domain user in dcm.dell.com. Use the following commands to create service SPN on the dcm.dell.com domain controller.

setspn -a HTTP/server1.east.dcm.dell.com Jack

setspn -a HTTP/server1 Jack

Step 3. Configure Web browser

You must configure your Web browser to support SSO. For more information on the configuration, see step 3 of "Single Domain Environment" in this chapter.

Windows NT LAN Manager (NTLM) Authentication Limitation

Power Center supports Kerberos SSO for Windows domain user authentication. To enable this feature, Power Center is configured to support the Windows integrated authentication option which includes two authentication mechanisms: Kerberos and NTLM .

NTLM is not supported in Power Center. If the client’s Web browser uses NTLM to authenticate domain users for Power Center, there are some limitations.

Access Control 38

What's the limitation?

The Web browser displays a message box requiring a Windows user name and password:

•If you press OK after entering a user name and password, whether the information is correct or not, the Power Center login page appears and requires you to authenticate through the login page.

•If you press log into Power Center.

When does this occur?

When one of the following elements of Kerberos SSO is not correctly configured: Power Center server, Web browser or AD domain controller configuration.

How to solve?

Correctly configure your Power Center server, AD controller and Web browser for Kerberos SSO. For more information on how to configure, see the section above and your Web browser Help.

This chapter explains how to discover devices from the network and add devices manually in the Power Center management console.

Power Center device discovery includes both the automatic detection of all devices on your data center and the collection of basic information about each device, such as the device name, connection status, device type, device model, its IP address and hostname, and the protocol it uses for communication. This enables you to track the device status and your data center information. You can also manage these discovered devices in Power Center. If there is a new or changed device in your data center, you can use the device discovery function to rediscover the devices.

You must have the "Manage Device/Group" and "Discover Device" privileges to add a device to Power Center.

There are two scenarios for adding devices:

• Add a device from the network — You can discover a device from the network. The discovered devices will be automatically added to the Device List.

• Add a device manually console to specify device properties and add a device to the Device List.

— You can use the Power Center management

NOTE: If you use a network security policy, the discovery function may not work

properly.

Supported Devices and Unsupported Devices

You can add or discover supported devices, and create a group structure to build out the data center. Power Center cannot discover or manage all device types, and unsupported devices must be added manually to make the data center group structure complete.

For supported devices:

Device Discovery 51

• Device types include server, UPS, PDU and chassis.

• Set the connection protocol and credential information so that the device can communicate with Power Center.

• Add or discover a supported device to the Device List. Perform management functions including discovery, adding to the group structure, monitoring power and temperature, applying power management policies, and sending events.

For unsupported devices:

• Power Center does not communicate with unsupported devices, therefore connection protocol and credential information is not necessary.

• Unsupported devices cannot be discovered, only added manually to the Device List.

• Power Center adds the unsupported device to the group structure, but cannot manage it using the available management functions.

You may need to enter the following power values when adding supported or unsupported devices:

•

Faceplate Power:

Adding a Device from the Network

This section explains how to use the Power Center management console to discover a device from the network.

Before adding a device from the network, make sure the DNS server is set up correctly. Specifically, make sure that:

• There is a DNS server running on the Power Center’s network.

• The specified DNS server has a reverse DNS zone for the network on which you are trying to discover the devices.

Device Discovery 52

NOTE: Power Center server tries to get device names from the DNS server

specified in the network configuration of the operating system. This may cause the device name to be different from the actual one if the DNS server resolves the device IP address to a different device name.

To discover devices from the network, complete the following steps:

Step 1. Enter IP Range

Group Management

You can configure several devices as a group so that you can manage them.

Power Center enables you to create and organize your devices into two distinct types of groups:

•Physical Group

A physical group is a group of groups/devices with a structure mapping that represents the actual physical layout.

For more information on how to create and manage physical groups, see the "Physical Groups" chapter.

• Logical Group

A logical group is a collection of groups and devices with a logical relation. A logical group does not need to map with the actual physical layout.

For more information on how to create and manage logical groups, see the "Logical Groups" chapter.

Mapping Group Structure Information

Power Center supports group stucture mapping for Dell PowerEdge rack servers and tower servers. For more information on the specific models, see "Supported Devices" in the "Overview" chapter.

After you have created or updated the group structure, Power Center automatically updates the location information in the firmware of supported devices at the following mapping structure:

• Data Center — format: <Data Center - Room>.

•Aisle

•Rack

• Rack Slot

• Chassis

— Aisle information in Power Center.

— Rack information in Power Center.

— Chassis information in Power Center (if applicable).

Power Monitoring

Power Center enables the monitoring of current or historical power-related metrics (for example, power consumption or cost). This can help you understand the power status in the data center and plan for additional power infrastructure, cooling, and facility needs.

You can monitor power at different device/group levels, you can configure power monitoring settings to meet your monitoring needs, and you can also print the power status graph.

Power Monitoring Level

Power Center provides power monitoring at the following levels:

For physical groups and logical groups:

• Individual device

•Rack

•Aisle

• Room

• Data center

For logical groups only:

• User-defined logical group

Power Monitoring Configuration

You can configure power monitoring settings in Power Center, including:

• Thresholds (Average, maximum power for events)

• Device and group range (Monitor all or not)

• Sampling interval (1, 3, 6 minutes)

• Default units (Watts, or BTU per hour)

• Energy consumption (Power consumption and cost)

Power Monitoring 78

Thresholds is useful if you want to be notified when the power of the group/device exceeds the thresholds. Once the power value exceeds a critical or warning threshold, the related event is sent.

To configure thresholds:

Go to

Power Overview → Select a Physical Group or Device

For example, when you view power details in the 1H (1 hour) window, the maximum value at 15:00 shows 500W and the time interval is 6 minutes, this value represents the maximum power consumption from 14:54 to 15:00 is 500W.

NOTE: It is common to see some instantaneous values exceed the Power Cap

value in the Maximum line. Power Center monitors this value and controls it to normal power range when this happens. You only need to pay attention when the

Average power value exceeds the Power Cap value.

NOTE: You can set the time interval (period from a time point to the next time point)

in the Settings page. For more information on how to configure the interval, see "Monitoring Settings" in the "Configuring" chapter.

For racks, you can also click Power Consumption to display PDU power consumption for all rack PDUs.

You can also click Power Policies to change a power policy.

NOTE: The Power Policies button is only enabled if you have configured a power

policy in the Policies page. For more information on how to configure a power policy, see the "Power Policies" chapter.

You can view the following power details of the PDU devices. For more information on supported PDU devices, see "System Requirements" in the "Overview" chapter.

• PDU device information: Including PDU name, model and IP address.

• PDU outlet information: Including outlet number, power(W), voltage (V), amps(A), and time of the information recorded, following this format: <YYYY-MM-DD HH:MM:SS>. The table lists the information for each outlet and the total power consumption for all outlets.

NOTE: For PDU outlet information, Power Center only supports the Dell Managed

Rack PDU 6605.

Viewing Energy Consumption

The Power Details page provides the following energy consumption information:

• IT Equipment Energy — managed devices in the selected device/group.

see the cost. The rate is a global setting, and can be set on the Settings → Energy

Consumption page.

NOTE: The Energy Consumption section displays information based on the values

configured in the Settings page. This information should be used as an estimate only.

NOTE: When a device or group is newly added or created in Power Center, the

power and energy consumption data displayed in the "1W" and "1M" time windows are different if the monitored time is less than 1 week, and the data displayed in the "1H" and "1D" time windows are different if the monitored time is less than 1 day. This occurs because Power Center uses different sampling intervals for different time windows. For example, a device is added into Power Center at 2011-10-15 09:00, and the current time is 2011-10-17 11:10. For the 1M time window (sampling interval is 1 day), the power and energy consumption is calculated from 2011-09-17 00:00 to 2011-10-17 00:00. For the 1W time window (sampling time is 1 hour), the power and energy consumption is calculated from 2011-10-10 11:00 to 2011-10-17 11:00. There is a 11 hour gap therefore the data displayed in the two time windows are not the same.

Power Policies

A power policy is a set of configurations used to manage the power cap for devices or groups. A policy is useful for defining power management in different situations, for example:

• You can set up a policy to make sure that the power consumption does not exceed the capacity of the circuit.

• You can set up a policy with a scheduled time according to the workload of the device/group; for example, you can set an aggressive cap when the workload is low, enabling a reduction of power use for your data center.

• You can set up a policy to increase the rack density. For example, you currently have ten devices in rack A_01 that is monitored by Power Center. By monitoring the power consumption from the can estimate how many devices you can add to rack A_01. You can set up a policy to cap the total power consumption of rack A_01 after you added the devices.

Power Center supports two policy types:

• Static power policy — The power cap for each device is defined by you, and will not be changed unless you redefine it. A static power policy enables you to set a power cap for each device in the group. You can create a static power policy for a rack, chassis or device.

•Dynamic power policy allocated by Power Center when necessary, based on the power consumption information and other power information on each device. Power Center evaluates power consumption for each device in every monitoring cycle to decide the necessity of changing the power cap for each device. A dynamic power policy enables you to allocate the power dynamically for each device in the group while maintaining the power cap for the group. A dynamic power policy has less performance impact to a device/group compared with a static power policy. You can create a dynamic power policy for a logical group, data center, room, aisle, rack, or chassis.

Power Policies 95

How Does a Dynamic Power Policy Work?

To understand how a dynamic policy works, you need to understand the following terms first:

• Consumption — The power a device is using.

•Power Cap consume (may not be equal to its demand).

• Headroom of a device or a group of devices under a power policy.

•Demand workload.

The top priority of the dynamic power policy is to maintain the power cap of the group. Maintaining this cap means that all devices can execute their workloads without needing more power than the cap. The priority of the device may not be taken into account when allocating power cap to a group of devices if most, or the entire power cap is allocated towards maintaining the power cap on each of the devices in the policy; if lower priority devices require more power to maintain their cap, they may actually receive more power than a higher-priority device. If the power cap is too restrictive and the group power consumption exceeds the power cap, an event is sent for the power policy. You need to reconsider the power allocation or adjust workloads when a power policy is consistently violated by one or more devices exceeding their power cap.

If fluctuations in device power requirements happen once the power cap is successfully established for all devices in a power policy, a device requiring more power may not get it as the power cap of another device in the policy could become violated as it is lowered. If you wish to force one or more devices in a policy to a lower cap, you can create a static power policy for the device at a lower level. In this case, the most restrictive power cap of the overlapping policies is applied to the device.

If there is excess available power from the power cap (known as headroom) after the power capping requirements is met for all devices in the policy, then this excess power can be allocated dynamically according to the priority and demand of the device in the power policy.

—

The maximum amount of power that a device is allowed to

—

The difference between power cap and power consumption

—

Amount of power a device requests to accommodate its

Power Policies 96

If the average power consumption of a device becomes lower than the power cap established for the device, its power cap is evaluated and adjusted in each monitoring cycle, and the excess power is deemed as headroom for other devices to consume.

Power Policy Capabilities

Power Center defines the following statuses of power policy capabilities for the devices:

• Unknown — Shown for unsupported devices or devices that were never connected to Power Center.

•None

•Monitor

• Monitor & Capping

• Monitor and Upgradable

You can find this power policy capability status in the Power Capability column of the Device List page.

For servers that comply with Dell iDRAC7, when there is a power policy capability change due to a license change, Power Center will change its information in the management console within 24 hours. There are two scenarios:

Scenario 1. The license expires or is not imported

In this case, the following happens:

To upgrade the device so that its power consumption can be capped, go to the Device List page and click Upgrade next to the device, then follow the instructions on the pop-up help page to upgrade the device power capability. Once the upgrade is completed, the power capability status changes to Monitor & Capping within 24 hours.

Creating a Policy

You can create static or dynamic policies for your device/group.

You can create static power policies for a rack, chassis or device, and create dynamic power policies for any group/device. Power policies only apply to the groups/devices that have Monitor & Capping power capability.

You can create multiple policies on the same device/group. This is useful when you want to apply different policies at different time periods for the same device/group.

values only refer to

the devices that have Monitor & Capping power capability.

Enter

Power Cap Value

for the

group/device:

•

Power cap value: Bound

. The Lower Bound is the lowest minimum power consumption

Enter a value between the

Lower Bound

and

since the device/group was either discovered/added. The Upper Bound is the maximum power consumption when the device/group is in a maximum workload state. You cannot enter a power cap value lower than the Lower Bound value. This value is the total power consumption budget for devices that have Monitor & Capping power capability.

•

Percentage of capability:

Enter a percentage (1%-100%) of the Upper

Bound value to set the power cap.

The "Power Cap Value" and "Percentage of Capability" are related values. The following formula describes the relationship between the two values:

Upper

Upper Bound * Percentage of Capability= Power Cap Value

NOTE: The default power cap unit is Watts. You can change this to a different unit.

For more information on how to change the default unit, see "Default Units Settings" in the "Configuring Power Center" chapter.

Allocate power for the group/device:

• For a dynamic policy, the priority (High, Medium, and Low) for the individual devices in the group can be changed as needed. After selecting the priority, click

Power Policies 99

NOTE: All devices are displayed on this page, but you only can configure priority

for the devices that have Monitor & Capping power capability.

NOTE: You can set priority levels based on the service level agreements

associated with workloads running on different devices/groups. P reserves more of the power for the devices/groups with a higher priority when the power cap is not completely utilized.

ower Center

• For a static policy, Power Center uses the same percentage of the Upper Bound value as the power cap for each device by default. You can enter a different value (Power Cap Value or Percentage of Capability), and click

NOTE:

•Time Stamp

If the sum of the entered device power cap is higher than the power cap value set in the previous step, Power Center will change the Power Cap Value and display a message prompt.
