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 multi-tenancy 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.
Creating a Server Pool
Procedure
Command or Action
Purpose
Step 1
UCS-A# scope orgorg-name
Enters organization mode for the specified organization. To enter the root organization mode, type / as the org-name.
Step 2
UCS-A /org # create server-poolserver-pool-name
Creates a server pool with the specified name, and enters organization server pool mode.
A server pool can contain more than one server. To create multiple servers for the pool, you must enter multiple create server commands from organization server pool mode.
Step 4
UCS-A /org/server-pool # commit-buffer
Commits the transaction to the system configuration.
The following example creates a server pool named ServPool2, creates two servers for the server pool, and commits the transaction:
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
Command or Action
Purpose
Step 1
UCS-A#
scope orgorg-name
Enters organization mode for the specified organization. To enter
the root organization mode, type
/ as the
org-name.
Step 2
UCS-A /org #
create uuid-suffix-poolpool-name
Creates a UUID suffix pool with the specified pool name and enters
organization UUID suffix pool mode.
Step 3
UCS-A /org/uuid-suffix-pool #set descrdescription
(Optional)
Provides a description for the UUID suffix pool.
Note
If your description includes spaces, special characters, or
punctuation, you must begin and end your description with quotation marks. The
quotation marks will not appear in the description field of any
show command output.
Creates a block (range) of UUID suffixes, and enters organization
UUID suffix pool block mode. You must specify the first and last UUID suffixes
in the block using the form
nnnn-nnnnnnnnnnnn, with the UUID suffixes
separated by a space.
Note
A UUID suffix pool can contain more than one UUID suffix block.
To create multiple blocks, you must enter multiple
create block commands from organization UUID
suffix pool mode.
Step 5
UCS-A /org/uuid-suffix-pool/block #
commit-buffer
Commits the transaction to the system configuration.
The following example creates a UUID suffix pool named pool4, provides
a description for the pool, specifies a block of UUID suffixes to be used
for the pool, and commits the transaction:
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:
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.

Step 1
UCS-A#
scope orgorg-name
Enters organization mode for the specified organization. To enter

Step 2
UCS-A /org # delete uuid-suffix-poolpool-name
Deletes the specified UUID suffix pool.
Step 3
UCS-A /org # commit-buffer
Commits the transaction to the system configuration.
The following example deletes the UUID suffix pool named pool4 and commits the transaction:
