Configuring Server-Related Pools
This chapter includes the following sections:
Configuring IP Pools
IP Pools
IP pools are a collection of IP addresses. You can use IP pools in Cisco UCS Central in one of the following ways:
- For external management of Cisco UCS Manager servers.
- For iSCSI boot initiators.
- For both external management and iSCSI boot initiators in Cisco UCS Manager.
 Note |
The IP pool must not contain any IP addresses that have been assigned as static IP addresses for a server or service profile. |
A fault is raised if the same IP address is assigned to two different Cisco UCS domains. If you want to use the same IP addresses, you can use the scope property to specify whether the IP addresses in the block are public or private:
- public—The IP addresses in the block can be assigned to one and only one registered Cisco UCS domain.
- private— The IP addresses in the block can be assigned to multiple Cisco UCS domains.
Cisco UCS Central creates public IP pools by default.
Global IP pools should be used for similar geographic locations. If the IP addressing schemes are different, the same IP pool can not be used for those sites.
Creating an IP Pool
What to Do Next
Include the IP pool in a service profile and/or template.
Deleting an IP Pool
If you delete a pool, Cisco UCS Central does not reallocate any addresses from that pool that have been assigned to vNICs or vHBAs in Cisco UCS Manager. 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 | On the menu bar, click Network. | ||
| Step 2 |
In the Network tab, expand . If you want to create or access a pool in a sub-organization, expand |
||
| Step 3 | Expand the IP Pools node. | ||
| Step 4 |
Right-click the pool you want to delete and select Delete.
|
||
| Step 5 | If Cisco UCS Central GUI displays a confirmation dialog box, click Yes. |
Configuring IQN Pools
IQN Pools
An IQN pool is a collection of iSCSI Qualified Names (IQNs) for use as initiator identifiers by iSCSI vNICs in a Cisco UCS domain. IQN pools created in Cisco UCS Central can be shared between Cisco UCS domains.
IQN pool members are of the form prefix:suffix:number, where you can specify the prefix, suffix, and a block (range) of numbers.
An IQN pool can contain more than one IQN block, with different number ranges and different suffixes, but sharing the same prefix.
Creating an IQN Pool
Note |
In most cases, the maximum IQN size (prefix + suffix + additional characters) is 223 characters. When using the Cisco UCS NIC M51KR-B adapter, you must limit the IQN size to 128 characters. |
| Step 1 | On the menu bar, click Storage. | ||||||||
| Step 2 |
In the Storage tab, expand . If you want to create or access a pool in a sub-organization, expand |
||||||||
| Step 3 | Right-click IQN Pools and select Create IQN Pool. | ||||||||
| Step 4 |
In the General tab of the Create IQN Pool dialog box, fill in the following fields:
|
||||||||
| Step 5 | In the IQN Blocks tab of the Create IQN Pool dialog box, click Create a Block of IQN Suffixes. | ||||||||
| Step 6 |
In the Create a Block of IQN dialog box, fill in the following fields:
|
||||||||
| Step 7 | Click OK. | ||||||||
| Step 8 |
Click OK.

What to Do Next
Include the IQN suffix pool in a service profile and/or template.

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. Assigning global UUID suffix pools from Cisco UCS Central to service profiles in Cisco UCS Central or Cisco UCS Manager allows them to be shared across Cisco UCS domains.
Creating a UUID Suffix Pool
| Step 1 | On the menu bar, click Servers. | ||||||||
| Step 2 |
In the Servers tab, expand . If you want to create or access a pool in a sub-organization, expand |
||||||||
| Step 3 | Right-click UUID Suffix Pools and select Create UUID Suffix Pool. | ||||||||
| Step 4 |
In the General tab of the Create UUID Suffix Pool dialog box, fill in the following fields:
|
||||||||
| Step 5 | In the UUID Blocks tab of the Create UUID Suffix Pool dialog box, click Create a Block of UUID Suffixes. | ||||||||
| Step 6 |
In the Create a Block of UUID dialog box, fill in the following fields:
|
||||||||
| Step 7 | Click OK. | ||||||||
| Step 8 |
Click OK.

Include the UUID suffix pool in a service profile and/or template.
