Power Systems Capacity Backup Edition (CBU for i) - overview One core is the minimum permanent entitlement required; however any production workload requires permanently licenses (for example replication workload) Primary Software tier primary CBU Software tier CBU The CBU offering is used in high availability and disaster recovery deployments Offering enables customers to move workload between boxes without fully redundant OS entitlements Two year temporary keys eliminate redundancy for eligible LPPs CBU designation available only upon purchase of a new box and must be registered to a qualified primary. If a CBU is no longer affiliated with the original registering customer, it is not recognized as a CBU. Registration process: client agrees to terms and conditions, CBU registration is validated, shipment is approved CBU agreement requires that both the primary and CBU are owned by the same enterprise.

IBM i OS entitlements not temporarily transferable as in the case of the CBU offering: i.e. IBM i OS entitlements must be acquired by the MSP for all workload that will run on the DBM. Two-year temporary keys for the non-os LPPs for the DBM are available by completing the form REQUEST FOR DESIGNATION OF A BACKUP IBM MACHINE. Products for which temp keys are acquired may not be used concurrently on primary and DBM DBM may be owned by MSP while hosted servers are owned by an MSP client. MSP is required to provide verification to the Compliance & Entitlement Support team that the CPW rating of the partition for the client does not exceed the CPW rating of the client machine (i.e. show from the HMC the processors allocated on the client's partition). DR tests: up to three days, four times per year per hosted client

Two year temp key request form Temp keys issued for LPPs not used concurrently on the primary and backup Temp keys are not issued for IBM i OS processors (5051) or users (5052) Must be renewed every two years 13

CBU for IBM i temporary transferable procedure A software key tells each system s license manager how many i processor license entitlements each system has. If the client ever runs or assigns more i work than the system has entitlements; then messages are periodically issued to the operator indicating the IBM is out of license compliance. By the terms of the IBM licensing agreement, the client must then bring the IBM into compliance by either a) reducing i workload or b) adding i processor license entitlements. Signing the additional license agreement for CBU temporary transfers documents that IBM and the client understand when entitlements can be transferred from the primary to the CBU system. (Signature is either a real signature or a click to accept.) IMPORTANT when entitlements are temporarily transferred to the CBU system, the software key information on neither machine is altered. Thus the CBU system will issue the out-of-compliance message indicating it is out of compliance The additional license agreement terms give permission to the client under this situation to ignore these messages. The client agrees to monitor the i usage on both the primary and CBU systems to ensure the i usage on the pair of machines does not exceed the total number of i processor license entitlements. In addition to IBM i processor license entitlement, P05 and processor group level systems have IBM i user entitlements. User entitlements are transferable from the primary to the CBU. If the primary system is an IBM i processor based system ( processor group or higher), and the CBU is a processor and user based system, you must purchase any required user entitlements on your CBU. 14

Frequently Asked Questions What happens if if the registration is not completed? The order will not be fulfilled. If the server option is not able to be registered, it most likely means that it is not supported I have this server that I want to convert into a CBU, can I do that? The only way to attain CBU designation is through the purchase of a new box or via a model upgrade You must include the CBU specify code when the upgrade is ordered Can reverse the roles of my Primary and CBU via a record change process? No. The only legitimate role change operation is when the workload is moved to and from the CBU. This is the purpose of the CBU offering; enabling role swap operations for the purpose of HA or DR operations. Can I use the additional processors on my CBU for running an AIX application? Assuming that you have sufficient capacity for your i partition, you may use other the processor cores for any purpose as long as you have purchased the processor activations and the commensurate entitlements. How many primary systems can I backup with my CBU? One dedicated IBM i system or dedicated partition may be paired to a dedicated Virtual CBU ( VCBU ) partition for the purpose of role swap operations. Each primary-cbu pairing will be licensed as though they were both stand-alone boxes. Both the primary and the CBU must be owned by the same enterprise 21

Frequently Asked Questions Can a service provider use the IBM i CBU offering to support multiple clients? Yes, as long as the service provider owns both the primary systems and the CBU systems, and hosted clients are on dedicated primary and corresponding dedicated VCBU partitions or stand alone systems, and Licensing requirements for traditional single client to a single CBU apply to any type of pairing. Can I register more than one CBU to a primary system? This is a configuration typically associated with a PowerHA cluster implementation. You will register each CBU against one given primary system: tell us in the comment section that you will be registering more than one CBU to this primary. Each CBU will need to be able to be registered as though it were a stand alone server being registered to the given primary. Are there any additional compliance conditions associated with multiple primary and/or multiple CBU topologies? It is required that you install and run the IBM Electronic Service Agent (ESA) and send monthly reports. For implementations not based on storage-based clustering configurations, e.g. PowerHA, which inherently manage the production workload to access only one node in the cluster configuration at a time, it is required that the primary and CBU partitions be managed such that the assigned processing units and assigned virtual processors for the VCBU partition are set to the minimum entitled cores prior to workload failover. The maximum processing units and virtual processors are set to the number of entitlements to which VCBU will expand upon a workload failover. (The inverse operation will be performed on the primary partition post failover. The primary will be set to the minimum entitled cores ) I'm using logical replication, how many cores do I need licensed on the CBU? Logical replication a hot backup solution therefore all workload associated with Logical Replication must be permanently licensed. If it requires two cores to process replication on the CBU, those must be permanently licensed. 22

Frequently Asked Questions How do I license multiple primary systems (partitions) and CBU partitions If you have multiple primary systems paired to a single CBU, each primary system will have its own dedicated CBU partition called a VCBU and the minimal OS entitlements will be purchased for each of the dedicated corresponding VCBU partitions per the terms and conditions. If you are an MSP hosting multiple clients, each client will have their own dedicated primary partition and a corresponding dedicated VCBU partition each of which is licensed as though they were stand alone systems ( the minimal OS entitlements will be purchased for each of the dedicated corresponding VCBU per the terms and conditions) Think of each partition as being a separate system or node in a cluster topology. For each partition on the CBU which is paired to a primary partition via an HA/DR relationship, a minimum of one of the processor cores in that partition must have the entitlement to accommodate the transfer of entitlements from the corresponding primary partition. What is the minimum required OS entitlement on the CBU? That is determined by the number of cores required to support permanent resident peak workload on the CBU or VCBU if your hosting multiple primary servers. For example, if a data replication tool consumes 6 processor cores on a VCBU during a peak workload; there must be a minimum of 6 IBM i entitlements permanently installed on the CBU. How do I license for environments where I have unlimited user entitlements and multiple customers? How many user entitlements do I need to acquire for the CBU? If you are planning to failover over a single client, the minimum number of user entitlements you will need to purchase for the CBU would be equal to the user entitlements required by the client with the largest number of user entitlements. I have 10 customers each in a micro partition. Can I temporarily transfer one of them to the CBU? No, only an entire processor entitlement is temporarily transferable. 23

Frequently Asked Questions Can I transfer all of my IBM i user entitlements? No, there will always be a minimum of one IBM i entitlement which is not transferable (and there will always be a minimum of one on the CBU). Note the minimum of one is not an absolute. If there is resident workload on the primary and/or CBU which is not temporarily transferred, those processor cores must be licensed permanently. For example, replication workload requires IBM i processor entitlements (and 5250 Enterprise Enablement activations or IBM i user entitlements) to support that operation at peak workload on both the primary and CBU or VCBU. I have a 750 primary and I would like to use a 720 as a CBU box, the 750 doesn t have user entitlements what do I do You will need to purchase as many user entitlements on the CBU as you intend to use in the event of a failover Can I have the primary system and CBU system in different countries? There is no restriction in the CBU agreement that prevents this. It is not a consideration from a CBU terms and conditions perspective. 24

Frequently Asked Questions Can the CBU ever function as a stand alone production system? The CBU is registered with a specific primary server and must remain so to be in compliance as a CBU. A box that is on the used market that was once a registered CBU is no longer recognized as a CBU and is not able to registered. At this point it s just another box and is not eligible to act as a CBU that can run with entitlements temporarily transferred from a primary. Any workload that is licensed on the CBU can be hosted there. For example, you may have an AIX partition or a development partition used as a primary location. This is business as usual for those environments. The CBU Ts and Cs apply specifically to the primary and secondary IBM i HA/DR environments to be used for role swap purposes. What type of HA or DR solution can I use with my IBM CBU for i? You may use any approach you choose including a cold/warm backup based on tape recovery. If I am using a cold/warm backup solution for multiple primary systems, do I still need to have a VCBU for each partition? If you are using a cold/warm backup recovery technology such as restore from a tape backup, and you can recovery only one primary server at any given time, then you can host multiple primaries to a single CBU without implementing a VCBU configuraiton. If on the other hand you intend to recovery more than one primary at a time, each of those must have their own VCBU just as in the case of a hot backup technology. 25 What does temporary mean when used in the context of transferring optional IBM i user entitlements or optional IBM i processor entitlements? Temporary means that the transferred entitlements belong to the primary system. If the primary system goes away, all optional transferred IBM i user entitlements, Enterprise Entitlements and IBM i license entitlements remain with the primary system. When you initially configure your licensing topology, all transferable entitlements will be configured on the primary system. In effect you are entitled to run your production workload either on the primary partition or on the corresponding CBU partition but not concurrently.

Frequently Asked Questions For which Licensed Program Products can I get temporary keys for the CBU? You can get temporary keys for the IBM i non-os LPPs which are delivered as part of the IBM i keyed programs. How do I get temporary keys? The temporary key form can be requested from the Key Center at WWSWKEYS@dk.ibm.com. Is SWMA transferable to the CBU? No, in fact, if you would like IBM support and the ability to do upgrades, you need the SWMA on the entitlements that you purchased for the CBU to be current. Can I change my CBU back into a primary box? If this machine is no longer going to function as CBU, you can submit an RPOMES order to remove the CBU feature 0444 from the HW. Can I register an IBM i solution edition box as a CBU No. The CBU and Solution Edition are mutually exclusive offerings. 26
