Contents

As an administrator, your responsibility includes configuring the Scalability Server and agent policies for implementing NASD. You can identify the group of computers that can serve as Collaborating Agents for software distribution. When you enable agent collaboration on the Scalability Server, the Neighbor Aware Agents in the group can download software packages from the Collaborating Agents or Scalability Server depending on the policy configuration.
Configure Scalability Server Policy
Follow these steps:
  1. Open DSM Explorer and navigate to
    Control Panel
    ,
    Configuration
    ,
    Configuration Policy
    ,
    Default Computer Policy
    ,
    DSM
    ,
    Software Delivery
    ,
    Scalability Server
    , and click
    Neighbor Aware Software Distribution
    .
    The NASD policies for Scalability Server appear.
  2. Double-click each policy and configure the following policies as appropriate:
    • Exclusion list
      Defines a list/range of agent IP addresses to be excluded from collaboration. This list can include agents from other subnet, agents connected Wireless, ENC and VPN.
      These agents do not participate in Neighbor Aware Software Distribution and directly connect to the Scalability Server for downloading software packages.
    • Enable Agent Collaboration for Software Deployment
      Enables the NASD feature at Scalability Server level.
      • Value set to True
        Setting the value to true allows only the configured number of Collaborating Agents to connect to the Scalability Server and download the software package.
      • Value set to False
        If the value is set to False, then all the agents follow the standard software distribution process.
      Default:
       False
    • Max Agents in a Subnet that can download from SS Directly
      Defines the maximum number of agents in a subnet that can download the packages from Scalability Server. This setting is applicable for each job container.
      Only the defined number of Collaborating Agents, which first connect to the Scalability Server in the subnet, can download the software package directly from the Scalability Server.
      Default:
       5
    • Package Download Policy
      Determines how the agent would download package from other Collaborating Agents.
      • Value set to 0
        Collaborating Agents and Neighbor Aware Agents cannot connect to other subnet to download the software package. They must download from the Collaborating Agents in the same subnet. If Scalability Server is in the same subnet, then they can download from Scalability Server also.
      • Value set to 1
        Collaborating Agents and Neighbor Aware Agents can connect to the Collaborating Agents in the same subnet as well as other subnets on which the package is available, including the Scalability Server to download the software package. The agents would choose the nearest subnet, if they cannot get the package from collaborating agents within the same subnet.
      Default:
       1
      Irrespective of the policy value, if IntelliRollup patches are not available at Collaborating Agents, the patches are downloaded from Scalability Server.
The Scalability Server is now configured for NASD.
Configure Agent Policy
Follow these steps:
  1. Open DSM Explorer and navigate to Control Panel, Configuration, Configuration Policy, Default Computer Policy, DSM, Software Delivery, Agent, and then click Neighbor Aware Software Distribution.
    The NASD policies for agents appear.
  2. Double-click each policy and configure as appropriate:
    • Enable Agent Collaboration
      Specifies the agent as a Collaborating Agent. Packages that are downloaded on this agent are used by Neighbor Aware Agents.
      • Value set to True
        Configures the agent as Collaborating Agent which can connect to the Scalability Server to download and store the software package making it available for the Neighbor Aware Agents.
      • Value Set to False
        Agent either acts as a Neighbor Aware Agent or Normal Agent depending on the Agent collaboration feature configured at Scalability Server.
      Default:
       False
    • Maximum Number of Concurrent File Transfers
      Specifies the maximum number of concurrent file transfers the Collaborating Agent can support.
      The configured number of simultaneous Collaborating and Neighbor Aware Agents can connect to the Collaborating Agents to download software package.
      Default:
       3
    • Package Cleanup Policy
      Defines the package clean-up policy on Collaborating Agents.
      • After Configured time
        The package is deleted after configured Package Clean-up Time days.
      • On startup
        The cached packages are cleaned on the next start of SD agent. Running Caf register command also starts the SD agent.
      Default:
       After Configured time
    • Package Max Age
      Specifies the number of days the downloaded packages can be kept on the Collaborating Agent for Neighbor Aware Agents to download. The packages are retained and deleted after the configured time period.
      Default:
       7
The agent policy is now configured for NASD.
