Create an IP Pool
The specific steps to install vCenter
Operations require the preparation of an IP pool and then the
deployment of an Adapter virtual machine. You can then import and
configure the vCenter Operations vApp and then configure the adapter.
The adapter aggregates information from the View Connection Server,
vComposer, and vCenter and feeds it to vCenter Operations. To create an
IP pool, follow these steps:
1. Launch the vSphere client.
2. From the Home screen, select Networking.
3. From the left pane, ensure you have selected your datacenter, and on the right, select the IP Pools tab (see Figure 2).
Figure 2. Configure an IP pool.
4. Click Add to add an IP pool configuration.
5. Provide a name and
configure a set of IP addresses. There are various ways to do this; you
can use a restrictive subnet mask to provide only the number of IPs
required. In the case of vCenter Operations, you need one for Analytics
and UI virtual appliances, so you can use /30 to provide two IPs, as
shown in Figure 3.
The interface accepts the mask in Classless Inter Domain Routing (CIDR)
format and then translates it to a subnet mask, which requires the
slash (/) and prefix number.
Figure 3. Specify the mask in CIDR format (/30).
The other method of specifying IPs is
to use a smaller subnet mask and provide a range of IP addresses. In
this case, you may use a 24-bit subnet mask and enter a range such as
10.0.1.20#2, for example. You can configure IPv6 addresses or tell the
pool to actually use an existing DHCP service under the DHCP tab. DNS
name servers, domains, and search prefixes can be configured under the
DNS tab. If you are using an HTTP proxy, you can specify it under the
Proxy tab.
6. After you configure
the details for the networking attributes, you can associate the IP
pool to a certain port group to enable the use of the addresses, as
shown in Figure 4. After making the association, click OK to enable the pool.
Figure 4. Associate the IP pool to the port group.
