Lenovo XClarity Controller 2 (XCC2)

Most of the Lenovo ThinkSystem V3, ThinkAgile V3, and ThinkEdge V3 servers contain an integrated service processor, XClarity Controller 2 (XCC2), which provides advanced service-processor control, monitoring, and alerting functions. The XCC2 consolidates the service processor functionality, super I/O, video controller, and remote presence capabilities into a single chip on the server system board.

XCC2 is based on the AST2600 baseboard management controller (BMC) using a dual-core ARM Cortex A7 32-bit RISC service processor running at 1.2 GHz. XCC2 integrates four 10/100/1000 Mbps Fast Ethernet MACs compliant with IEEE802.3 and IEEE802.3z specification.

XCC2 has the capability to manage and configure multiple XCC2s from the one console. For more information see the Neighbor Group section.

With the System Guard feature, you can monitor hardware inventory for unexpected component changes, and simply log the event, or if needed, you can prevent the servers from booting. For more information, see the System Guard section.

There are two levels of features of XCC2: Standard and Platinum. Compared to the XCC functions of ThinkSystem V2 and earlier systems, XCC2 Platinum adds the same features as Enterprise and Advanced levels in XCC, plus additional and new features.

The XCC can be accessed remotely via these methods:

• Command-line interface. To access the CLI interface, use SSH to log in to the management processor.
• Web-based interface. To access the web-based interface, point your browser to the IP address for the management processor. The new intuitive interface includes at-a-glance visualizations and simple access to common system actions. The dashboard is shown in the following figure.

Figure 2. XClarity Controller 2 Web interface dashboard

XCC2 can also be accessed remotely through industry-standard interfaces:

• Intelligent Platform Management Interface (IPMI) Version 2.0
• Simple Network Management Protocol (SNMP)
  • Version 3 supported (no SET commands)
  • Version 1 supported, traps only
• Common Information Model (CIM-XML)
• Data Center Manageability Interface (DCMI) Version 1.5
• Representational State Transfer (REST) support
• Redfish support (DMTF compliant) currently with specification v1.15.0 -schema bundle is 2021.4
• Web browser - HTML 5-based browser interface (Java and ActiveX not required) using a responsive design (content optimized for device being used - laptop, tablet, phone) with NLS support

Models of ThinkSystem V3 servers come with either XCC2 Standard or XCC2 Platinum, depending on the server type and the model, as described in the Server support section.

Important considerations:

• If you will be using XClarity Administrator for tasks such as remote control and Bare Metal Operating System Deployment then the XCC Platinum level must be installed on the server.
• XClarity Controller 2 Platinum license includes hardware license for Lenovo XClarity Energy Manager (LXEM), a power and temperature management solution for data centers.

The following table shows the field upgrades available for models that come with XCC Standard.

For configure-to-order (CTO) models, you can specify the XCC2 level you require by selecting the appropriate XCC2 feature code as listed in the following table.

The following table shows what level of XCC2 is included with each ThinkSystem V3 server.

The XCC2 provides a security dashboard which shows an overall security assessment and status of the system. Providing status on:

• BMC Security Events report events asserted by security issues, such as chassis intrusion, PFR detected corruption, System Guard detected hardware inconsistency, security jumper open on planar, etc.
• BMC Security mode provides an overall status of Security Mode compliance.
• BMC Services & Ports enumerate all insecure services/ports enabled but non-compliant with the current Security Mode.
• BMC Certificates list all non-compliant certificates used by XCC.
• BMC User Accounts provide general suggestions on how to make the account and password management more secure.

The dashboard shows a warning icon if there is any risk in these security areas scanned by XCC. The detail link under each category also brings the user to the setup page to solve the issues.

With XCC2-based servers, customers can create a service forwarder that automatically sends service data for any managed device to Lenovo Support using the Call Home function.

Figure 4. XCC2 Call Home

When enabled, Call Home automatically contacts Lenovo to open a service ticket and sends in service data collected from a managed device whenever that device reports a hardware failure.

Service data that you would typically upload manually to Lenovo Support is automatically sent to the Lenovo Support Center over HTTPS using TLS 1.2 or later.

If the customer is managing their servers with XClarity Administrator they can choose to configure centralized Call Home via XClarity Administrator, rather than at each XCC or XCC2 instance. XClarity Administrator will additionally provide the capability to view information about service tickets that were manually and automatically submitted to the Lenovo Support Center using Call Home, including the current status and associated service files that were transferred to the Lenovo Support Center, and service tickets that were generated by support services other than Call Home.

For full details see XClarity Administrator (LXCA) working with service and support.

For details on which events per system will automatically notify support, go to Events and alerts for servers page in the LXCA User Guide, click the link for the specific server, then select submenu entry for XCC events that automatically notify Support.

Compared to the XCC, XCC2 Platinum license adds the same features as Advanced and Enterprise levels combined in XCC, plus additional features.

The new features included with XCC2 Platinum are as follows:

• System Guard – Monitor hardware inventory for unexpected component changes, and simply log the event or prevent booting.
• Enterprise Strict Security mode – Enforces FIPS 140-3 level security and enhanced NIST 800-193
• Neighbor Group Feature Group – Enables administrators to manage and synchronize configurations and firmware level across multiple servers.
• XCC2 Service Log – New service tool that provides XCC first-failure logs in HTML and JSON format.

For details, see the following sections:

• System Guard
• Enhanced Security Modes
• Neighbor Group
• Service Log

Figure 5. System Guard in XCC2

User can also take a snapshot at any time even while the feature is disabled. The generation of snapshot takes around one minute. User can select a subset of hardware components to enforce and select a corresponding action to take when deviation is detected.

Deviation detection is executed at server power on (POST) or system reboot. For example, while the OS is still running, if a disk drive is being pulled out and then plugged back in a moment later, System Guard is not going to record the event or take any action. If the extracted disk drive remains absent until next reboot, then System Guard would get in action.

For more information on working with System Guard see System Guard in the XCC2 User Guide.

Figure 6. Security Mode in XCC2

Each of the security modes has defined characteristics, as follows:

• Enterprise Strict Security Mode
  • Enterprise Strict Security Mode is the most secure mode.
  • NIST Compliant.
  • PFS-compliant (Perfect Forward Secrecy).
  • All cryptography algorithms used by BMC are enterprise strict compliant.
  • BMC operates in standard validated mode.
  • Requires enterprise strict grade certificates.
  • Only services that support enterprise strict level cryptography are allowed.
  • Requires Feature on Demand Key to enable.
• Standard Security Mode
  • Standard Mode is the default security mode.
  • NIST Compliant.
  • PFS-compliant (Perfect Forward Secrecy).
  • All cryptography algorithms used by BMC are standard compliant.
  • BMC operates in standard validated mode.
  • Requires standard grade certificates.
  • Services that require cryptography that do not support standard level cryptography are disabled by default.
• Compatibility Security Mode
  • Compatibility Mode is the mode to use when services and clients require cryptography that is not enterprise strict/standard compliant.
  • Non NIST and PFS (Perfect Forward Secrecy) compliant
  • A wider range of cryptography algorithms are supported.
  • When this mode is enabled, BMC is NOT operating in standard-validated mode.
  • Allows all services to be enabled.

For more information on configuring security modes refer to Security Mode in the XCC2 User Guide.

Typically, in the past, XCC could only manage a single server and XClarity Administrator (LXCA) facilitated scalability management to multiple servers. However, if LXCA is not deployed in the field, especially for SMB users, each node has to be configured one by one which is an inefficient process.

To counter this scenario, the XCC2 neighbor group feature provides a flexible way of initiating speedy deployment for multiple servers within a local network segment.

Figure 7. XCC2 Neighbor Group

The XCC neighbor group provides the following capabilities:

• Discover the neighbor nodes located in the same local network segment using Simple Service Discovery Protocol (SSDP) multicast message.
• Monitor the system health, and power status of the neighbor nodes.
• Configure neighbor group in leader node.
• Clone system configuration to multiple members of the neighbor group.
• Initiate concurrent firmware updates to multiple members of the neighbor group.
• The Leader node XCC supports a maximum of 200 nodes.

For more information on XCC Neighbor Group Management see Neighbor Group Management in the XCC2 User Guide.

Figure 8. Service log

By default, the service log will contains the following data: system information, system inventory, system utilization, SMBIOS table, sensors reading, events log, FOD key, SLP key, UEFI configuration and XCC2 configuration.

User can also mouse over the Basic Information option and click on the floating window to see some actual data to be exported, as shown in the following figure.

Figure 9. Mouse over additional information option

By clicking to see some actual data provides the user will be presented with a similar view to the following figure.

Figure 10. Example of Actual Data being exported

While Basic Information is mandatory, user has the option to additionally export the following information:

• Network information (IP, hostname)
• Telemetry (24 hours data)
• Audit log (contains username)
• Latest failure screen

XCC2 provides support for the industry standard Redfish Scalable Platforms Management API. The Redfish API can be used to access XCC2 data and services from applications running outside of the XCC2. This allows for easy integration of Lenovo XCC2 capabilities into Lenovo or 3rd party software. Redfish uses RESTful interface semantics and JSON resource payload to perform system management via the HTTPS protocol.

Lenovo additionally provides some Python and PowerShell sample scripts to use Redfish. These are available as open-source code on Lenovo’s Github page http://github.com/lenovo/

• Lenovo Python Redfish Scripts: https://github.com/lenovo/python-redfish-lenovo
• Lenovo PowerShell Redfish Scripts: https://github.com/lenovo/powershell-redfish-lenovo

These scripts utilize Redfish API to manage Lenovo ThinkSystem servers. Currently, the scripts support hardware/firmware inventory, basic management of configuration and control, firmware updates, and alerts/eventing. The scripts can be used both remotely (out-of-band to the XCC2 Network) and locally (in-band on the ThinkSystem server, connecting to the XCC2 local host Network interface).

Other open-source tools that support Redfish include Ansible, which added support for Redfish starting with version 2.7, in the form of three modules for Remote Hardware Management. These modules are tested on Lenovo ThinkSystem servers:

• redfish_facts: https://docs.ansible.com/ansible/latest/modules/redfish_facts_module.html
• redfish_command: https://docs.ansible.com/ansible/latest/modules/redfish_command_module.html
• redfish_config: https://docs.ansible.com/ansible/latest/modules/redfish_config_module.html
