Configuring Server-Related Pools
This chapter includes the following sections:
Configuring Server Pools
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 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. A given server can belong to multiple server pools.

Configuring UUID Suffix Pools
UUID Suffix Pools
A UUID suffix pool is a collection of SMBIOS UUIDs that are available to be assigned to servers. The first number of digits that constitute the prefix of the UUID are fixed. The remaining digits, the UUID suffix, are variable. A UUID suffix pool ensures that these variable values are unique for each server associated with a service profile which uses that particular pool to avoid conflicts.
If you use UUID suffix pools in service profiles, you do not have to manually configure the UUID of the server associated with the service profile.
Creating a UUID Suffix Pool
Step 1 | In the Navigation pane, click the Servers tab. | ||||||||||
Step 2 | On the Servers tab, expand . | ||||||||||
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 UUID Suffix Pools and select Create UUID Suffix Pool. | ||||||||||
Step 5 | In the Define Name and Description page of the Create UUID Suffix Pool wizard, complete the following fields:
| ||||||||||
Step 6 | Click Next. | ||||||||||
Step 7 | In the Add UUID Blocks page of the Create UUID Suffix Pool wizard, click Add. | ||||||||||
Step 8 | In the Create a Block of UUID Suffixes dialog box, complete the following fields:
| ||||||||||
Step 9 | Click OK. | ||||||||||
Step 10 | Click Finish to complete the wizard. |
What to Do Next
Include the UUID suffix pool in a service profile and/or template.
Deleting a UUID Suffix Pool
If you delete a pool, Cisco UCS Manager does not reallocate any addresses from that pool that have been assigned to vNICs or vHBAs. All assigned addresses from a deleted pool remain with the vNIC or vHBA to which they are assigned until one of the following occurs:
Configuring IP Pools
IP Pools
IP pools are a collection of IP addresses that do not have a default purpose. You can create IP pools in Cisco UCS Manager to do the following:
Replace the default iSCSI boot IP pool iscsi-initiator-pool. Cisco UCS Manager reserves each block of IP addresses in the IP pool that you specify.
Replace the default management IP pool ext-mgmt for servers that have an associated service profile. 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 both the management IP address and iSCSI boot IP addresses.
Note | The IP pool must not contain any IP addresses that have been assigned as static IP addresses for a server or service profile. |
Creating an IP Pool
Step 1 | In the Navigation pane, click the LAN tab. | ||||||||||||||
Step 2 | In the LAN tab, expand . | ||||||||||||||
Step 3 | Right-click IP Pools and select Create IP Pool. | ||||||||||||||
Step 4 | In the
Define Name and Description page of the
Create IP Pool wizard, fill in the
following fields:
| ||||||||||||||
Step 5 | Click Next. | ||||||||||||||
Step 6 | In the Add IP Blocks page of the Create IP Pool wizard, click Add. | ||||||||||||||
Step 7 | In the
Create a Block of IP Addresses dialog box, fill in the
following fields:
| ||||||||||||||
Step 8 | Click OK. | ||||||||||||||
Step 9 | Click Finish to complete the wizard. |
What to Do Next
Include the IP pool in a service profile and/or template.
Adding a Block to an IP Pool
Step 1 | In the Navigation pane, click the LAN tab. | ||||||||||||||
Step 2 | In the LAN tab, expand . | ||||||||||||||
Step 3 | Expand the IP Pools node. | ||||||||||||||
Step 4 | Right-click the desired IP pool and select Create Block of IP Addresses. | ||||||||||||||
Step 5 | In the
Create a Block of IP Addresses dialog box,
complete the following fields:
| ||||||||||||||
Step 6 | Click OK. |
Deleting a Block from an IP Pool
Step 1 | In the Navigation pane, click the LAN tab. |
Step 2 | In the LAN tab, expand . |
Step 3 | Expand the IP Pools node. |
Step 4 | Expand the pool for which you want to delete a block of IP addresses. |
Step 5 | Right-click the IP address block that you want to delete and select Delete. |
Step 6 | If the Cisco UCS Manager GUI displays a confirmation dialog box, click Yes. |
Deleting an IP Pool
If you delete a pool, Cisco UCS Manager does not reallocate any addresses from that pool that have been assigned to vNICs or vHBAs. All assigned addresses from a deleted pool remain with the vNIC or vHBA to which they are assigned until one of the following occurs:
Step 1 | In the Navigation pane, click the LAN tab. | ||
Step 2 | In the LAN tab, expand . | ||
Step 3 | Expand the IP Pools node. | ||
Step 4 | Right-click the IP pool you want to delete and select
Delete.
