IP pools are collections of IP addresses that do not have a default purpose. You can create IPv4 or IPv6 address pools in the Cisco UCS Manager to do the following:
Replace the default management IP pool ext-mgmt for servers that have an associated service profile. The Cisco UCS Manager reserves each block of IP addresses in the IP pool for external access that terminates in the Cisco Integrated Management Controller (CIMC) on a server. If there is no associated service profile, you must use the ext-mgmt IP pool for the CIMC to get an IP address.
Replace the management in-band or out-of-band IP addresses for the CIMC.
Note
You cannot create iSCSI boot IPv6 pools in the Cisco UCS Manager.
You can create IPv4 address pools in the Cisco UCS Manager to do the following:
Replace the default iSCSI boot IP pool iscsi-initiator-pool. The Cisco UCS Manager reserves each block of IP addresses in the IP pool that you specify.
Replace both the management IP address and iSCSI boot IP addresses.
Note
The IP pool must not contain any IP addresses that were assigned as static IP addresses for a server or service profile.
An example of creating a management IP pool is as follows:
Step 1. In the Navigation pane, click the LAN tab. In the LAN tab, expand LAN > Pools > Organization_Name.
Step 2. Right-click IP Pools and select Create IP Pool.
Step 3. In the Define Name and Description page of the Create IP Pool wizard, complete the following fields:
Step 4. Click Next.
Step 5. In the Add IPv4 Blocks page of the Create IP Pool wizard, click Add.
Step 6. In the Create a Block of IPv4 Addresses dialog box, complete the following fields (see Figure 12-47):
Figure 12-47 Creating an IP Pool
Step 7. Click Next.
Step 8. In the Add IPv6 Blocks page of the Create IP Pool wizard, click Add.
Step 9. In the Create a Block of IPv6 Addresses dialog box, complete the following fields:
Step 10. Click OK, and then click Finish to complete the wizard.
Server Pools
A server pool contains a set of servers. These servers typically share the same characteristics. Those characteristics can be their location in the chassis or an attribute such as server type, amount of memory, local storage, type of CPU, or local drive configuration. You can manually assign a server to a server pool, or you can use server pool policies and server pool policy qualifications to automate the assignment.
If your system implements multitenancy through organizations, you can designate one or more server pools to be used by a specific organization. For example, a pool that includes all servers with two CPUs could be assigned to the Marketing organization, while all servers with 64-GB memory could be assigned to the Finance organization. A server pool can include servers from any chassis in the system, and a given server can belong to multiple server pools.
An example of creating a server pool using Cisco UCS Manager is as follows:
Step 1. In the Navigation pane, click Servers.
Step 2. Expand Servers > Pools.
Step 3. Expand the node for the organization where you want to create the pool. If the system does not include multitenancy, expand the root node.
Step 4. Right-click the Server Pools node and select Create Server Pool.
Step 5. On the Set Name and Description page of the Create Server Pool wizard, complete the following fields:
Step 6. Click Next.
Step 7. On the Add Servers page of the Create Server Pool wizard:
Select one or more servers from the Available Servers table.
Click the >> button to add the servers to the server pool.
When you have added all desired servers to the pool, click Finish.
