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
Procedure
Step 1
| In the
Navigation pane, click
Servers.
|
Step 2
| 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 5
| In the Define Name and Description page of the Create UUID Suffix Pool wizard, complete the following fields:
Name
|
Description
|
Name field
|
The name of the UUID pool.
This
name can be between 1 and 32 alphanumeric characters. You cannot use spaces or

(period), and you cannot change this name after the object is saved.
|
Description field

Deleting a UUID Suffix Pool
If you delete a pool,
Cisco
UCS Manager does not reallocate any addresses from that pool that were
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:
-
The associated
service profiles are deleted.
-
The vNIC or
vHBA to which the address is assigned is deleted.
-
The vNIC or
vHBA is assigned to a different pool.

Configuring IP Pools
IP Pools
IP pools are collections of IP addresses that do not have a default purpose. You can create IPv4 or IPv6 address pools in Cisco UCS Manager to do the following:
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 the management inband or out-of-band IP addresses for the CIMC.
 Note |
You cannot create iSCSI boot IPv6 pools in Cisco UCS Manager.
|
You can create IPv4 address 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 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.
