Locating the
Global Manager
s in the network

In choosing locations for the platforms that support the
Global Manager
s, there may be restrictions on locations that are not related to network and application efficiency. Locating the
Global Manager
s may be based on the following considerations:
  • Geographical requirements: An organization may require that all
    VMware Smart Assurance
    Managers be based in a single Network Operations Center (NOC). Other organizations might have the
    Global Manager
    in the NOC and underlying Domain Managers located in regional data centers.
  • Corporate organizational requirements: For example, organizations that have a distributed business management might require that components be located to match the organization’s structure.
    Communication between applications is influenced by network speed and latency. Avoid configurations that require a
    Global Manager
    to receive information from other applications across WAN links with high latency. Instead, consider placing
    Global Manager
    s on both ends of high-latency WAN links. The hierarchical
    Global Manager
    configurations can be used to eliminate high-latency link issues for these situations:
  • Domain Manager
    s that connect to a
    Global Manager
    over a high-latency link: Use the basic hierarchical, hierarchical aggregation, or hierarchical mesh configuration to place a
    Global Manager
    on the same side of the high-latency link as the
    Domain Manager
    s.
  • A group of clients that connect to a
    Global Manager
    over a high-latency link: Use the basic hierarchical, hierarchical presentation, or hierarchical mesh configuration to place a
    Global Manager
    on the same side of the high-latency link as the group of clients.
    After you determine the configuration and locations of the
    Global Manager
    s, add system names and
    Global Manager
    names to your solution architecture diagram. Define IP addresses and dedicated port numbers when needed. Establish a host naming convention and a
    Global Manager
    naming convention before you settle on any names.
