A numeric value of 5 indicatesthe highest priority for remaining within acoustic noise limits bylimiting the amount the fan speed can be increased. As a result, thissetting increases the possibility that the node might have to be throttledto remain within the acoustic noise limit. As the setting number increases,less priority is placed on remaining within acoustic noise limits.
  • NEBS/Acoustic Attenuation (Carrier-Grade Chassisonly) -
    • If NEBS Cooling Mode Override is selected, fan speeds andnoise limits are optimized for environmental conditions while maintainingNEBS compliance.
    • If NEBS Cooling Mode Override is not selected, theuser can set a policy for how quickly the chassis fan speed increasesif there is a thermal event on the selected node. When the optionis set to Off, the fan speed will increase without concernfor acoustic noise limits. A numeric value of 5 indicates the highestpriority for remaining within acoustic noise limits by limiting theamount the fan speed can be increased. As a result, this setting increasesthe possibility that the node might have to be throttled to remainwithin the acoustic noise limit. As the setting number increases,less priority is placed on remaining within acoustic noise limits.
Chassis ManagementPower Modules and ManagementThe Power Modules and Management page containspower management policies and power hardware information. The followingtabs are available:
  • Policies - Contains options to configure power policies for powerredundancy, in case of power module failure, and power limiting. Thefollowing policies are available on the Policies tab:
    • Power Redundancy Policy - Options to configure a backup powersource for the chassis. The following options are available:
      • Power Source Redundancy - This option is intended fordual power supplies in the chassis. Maximum input power is limitedto the capacity of half the number of installed power modules. Thisis the most conservative approach and is recommended when all powermodules are installed. When the chassis is wired with redundant powersources, one power source can fail without affecting compute nodeoperation. Some compute nodes might not be allowed to power on ifdoing so would exceed the policy power limit.
      • Power Source Redundancy with Compute Node ThrottlingAllowed - This option is similar to the Power Source Redundancy policy;however, this policy allows higher input power, however capable computenodes might be allowed to throttle down if one power source fails.
      • Power Module Redundancy - Intended for a single power source inthe chassis where each power module has its own dedicated circuit.The maximum input power is limited to the power of one less than thetotal number of power modules when more than one power module is present.One power module can fail without affecting compute node operation.Multiple power module failures can cause the chassis to power off.Some compute nodes might not be allowed to power on if doing so wouldexceed the policy power limit.
      • Power Module Redundancy with Compute Nodes Throttling Allowed- This option enables higher input power, similar to the Power ModuleRedundancy option. Some compute nodes might be able to throttle downif a power module fails.
      • Basic Power Management - The maximum input power ishigher than the other policies and is limited only by the indicatedpower of all the power modules combined. This is the least conservativeoption, with no protection for power source or power module failure.When a power supply fails, compute node or chassis operation mightbe affected.

Chassis ManagementChassis Internal NetworkThe Chassis Internal Network (CIN) providesinternal connectivity between compute node ports and the internalmanagement module management port. This capability allows a user toaccess the CMM froma compute node, for example, by opening a web, CLI, or SNMP session.The communication path is two-way, so that the CMM canalso use services on the compute node, such as, LDAP, SMTP, DNS, andNTP.

The Chassis Internal Network page enables the user to monitorthe status of CIN sessions and change CIN parameters. The followingtabs are available:

  • General - Contains the options to enable or disable the CIN functionglobally. One of the following check boxes is available, dependingon the CIN current state:
    • Enable Chassis Internal Network - Activates the CIN
      • Management module reads the CIN entries
      • When an entry is enabled and the CIN VLAN ID is new and does nothave a CIN interface, a new CIN interface based on that CIN VLAN IDis created. Use the CIN IP address from the entry to create a hostroute.
      • When an entry is enabled and the CIN IP address is 0.0.0.0, startARP monitoring.
    • Disable Chassis Internal Network - Deactivates the CIN
      • Stops all ARP monitoring
      • Deletes all host routes
      • Deletes all CIN interfaces
  • Status - Contains a summary list of all CIN sessions in a table.The following properties are available for the list of CIN sessions:
    • CIN VLAN ID - Virtual LAN (VLAN) ID supporting CIN
    • CIN IP Address - IP address communicating on the CIN. An asterisk(*) after the address indicates that the address was dynamically createdand not configured by the user.
    • CIN MAC - MAC address associated with the IP address.
    • Status - CIN connection status:
      • Operational - CMM canping the CIN IP address.
      • Not Operational - The CMM cannotping the CIN IP address. Verify that the compute node and the I/Omodule are configured properly and the configurations are compatiblewith those of the CMM.
      • Disabled - CIN configuration was disabled by a CMM administrator.
  • Configuration - Contains a table of CIN entries that allows youto define, enable, disable, or delete CIN entries. A maximum of 14CIN configuration entries are supported. The table columns are asfollows:
    • Bay - Index between 1 and 14 (inclusive) to identify the CIN configuration.
    • CIN VLAN ID - Virtual LAN (VLAN) ID that supports CIN. Valuescan range from 3 to 4094 (inclusive). These VLAN IDs cannot be thesame as the one used for Serial over LAN (SOL).
  • Configuration
    • CIN IP Address - IP address that is allowed to communicate onthe CIN. The value of 0.0.0.0 indicates that any IP address can communicateon the CIN. In this case, the CMM listenson the CIN VLAN ID and learns the IP addresses dynamically. If youwant to restrict the addresses, you must define each IP address specifically.CIN entries cannot have matching IP addresses, with the exceptionof 0.0.0.0. Multiple CIN entries with an IP address of 0.0.0.0 areallowed, provided that the VLAN IDs are different. The IP addressof a CIN entry cannot be multicast or match the CMM IPaddress. If the CIN IP address is 0.0.0.0, the compute node IP addressfor the CIN that is configured in the compute node operating systemcannot be in the same subnet as the CMM.
    • Enable - Column that allows the user to enable, disable, or deletea CIN configuration:
      • Enabled - The CMM readsthe entry and creates a new CIN interface if the CIN VLAN ID is newand does not have a CIN interface, and then adds a host route andmonitors communication path. ARP monitoring is started if the IP isset to 0.0.0.0.
      • Disabled - The host route is deleted. If this is the last IP addressthat uses the CIN interface, ARP monitoring is stopped if the IP is0.0.0.0 and the CIN interface is deleted if there is no other entrythat depends on it.
Hardware TopologyThe Chassis Hardware Topology page containsa hierarchical view of the components in the chassis. The graphicalhardware topology tree is located on the left panel and displays componentsthat can be clicked to display all of the associated inventory datain the right panel. A parent component displays a +/- box and canbe expanded to show its associated child components. Click the parentcomponent to view information about the component and a table of itsassociated child components. The table contains inventory data foreach child component. When the lowest level child component is reached,you can click on the child component to view its inventory data.ReportsYou can generate hardware reports for all componentsthat have MAC addresses or unique identifiers from the Reports page.The following tabs contain tables with information about each connectedcomponent:
  • MAC Addresses - Contains summary information for all installedchassis devices that have MAC addresses.
  • Unique IDs - Contains summary information for all installed chassisdevices that have unique identifiers, including Fibre Channel WWNs,storage SAS IDs, and Infiniband GUIDs. The device type indicators:W, S, or G, are added after the name value to identify the type ofdevice.
  • Firmware Analysis - Contains the primary firmware levelsof installed nodes in the chassis. This information is grouped bymachine type/model and groups two or more nodes with the same type/model.This information is intended to be used for determining which componentsmight need firmware upgrades.
  • Component Firmware - Contains a listing of all installedfirmware for compute nodes, storage nodes, node network cards, andswitches.
  • IP Addresses - Contains a listing of all IP addressinformation for compute nodes, storage nodes, and switches.
VLAN Configuration
  • Global VLAN Settings - Contains the option to globally enableVLAN support for the CMM eth0 network interface. Configuring and applyingconfiguration changes might make the CMM inaccessible, for example,if there is a mismatch with the network environment. To prevent theCMM from becoming inaccessible, a temporary or uncommitted configurationis provided as a backup. Configuration changes made to VLAN parameterswill be temporary until the user accepts the changes. All uncommittedchanges can be committed by clicking Commit. If temporary changesare not committed within the selected revert timeout, the last committedconfiguration will be restored. This allows the user to access theCMM if the temporary changes resulted in inaccessibility. The reverttimeout can be configured for 1-255 minutes. The revert timer is startedwhen a configuration update is saved. The last committed changes arerestored when the revert timer expires, if the user did not committhe temporary configuration.
  • CMM VLAN Configuration - Contains the option to configure, add,remove, or restart a VLAN. A maximum of two VLAN entries can be configuredon the CMM. The first VLAN entry is referred as the default entry.The default entry is always enabled and initially has the SOL featureassigned to it. It is always configured with the IPv4 and IPv6 configurationof the CMM external eth0 network interface.
    • Actions
      • Add New VLAN - This option is used to define the second VLAN entry,using a unique name and VLAN ID. In addition, the VLAN state can beenabled and disabled and VLAN tagging can also be managed. The VLANmay be configured with unique IPv4 and IPv6 network parameters andstatic routes can be associated with each protocol.
        • Actions - Select the second VLAN entry and the Actions menu ismade available with options to delete or restart the VLAN.
      • Delete VLAN - This option is used to delete the second VLAN entry.
  • Features Assignment - Assigns the available features to a VLAN,or removes the feature assignment.
