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.

Creating a Server Pool

Procedure
    Step 1   In the Navigation pane, click the Servers tab.
    Step 2   On the Servers tab, expand Servers > Pools.
    Step 3   Expand the node for the organization where you want to create the pool.

          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 the Servers tab.
            Step 2   On the Servers tab, 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 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:
            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 any special characters other than - (hyphen), _ (underscore), : (colon), and . (period), and you cannot change this name after the object has been saved.

            Description field

            The user-defined description of the pool.

            Enter up to 256 characters. You can use any characters or spaces except ` (accent mark), \ (backslash), ^ (carat), " (double quote), = (equal sign), > (greater than), < (less than), or ' (single quote).

            Prefix field

            This can be one of the following:

            • Derived—The system creates the suffix.

            • other—You specify the desired suffix. If you select this option, Cisco UCS Manager GUI displays a text field where you can enter the desired suffix, in the format XXXXXXXX-XXXX-XXXX.

            Assignment Order field

            This can be one of the following:

            • DefaultCisco UCS Manager selects a random identity from the pool.

            • SequentialCisco UCS Manager selects the lowest available identity from the pool.

            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:
            Name Description

            From field

            The first UUID in the block.

            Size field

            The number of UUIDs in the block.

            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:

            • 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.

            Procedure
              Step 1   In the Navigation pane, click the Servers tab.
              Step 2   On the Servers tab, expand Servers > Pools > Organization_Name.
              Step 3   Expand the UUID Suffix Pools node.
              Step 4   Right-click the pool you want to delete and select Delete.
              Step 5   If the Cisco UCS Manager GUI displays a confirmation dialog box, click Yes.

              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.

                                  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.
