What describes the expression 'Power Flex' ?

Power Flex is a multi-system Power 795 infrastructure offering to provide a highly available and flexible IT environment to support large-scale server consolidation and an enterprise’s most demanding business resiliency objectives. Power Flex is designed to enable clients to use purchased processor and memory activations more flexibly across a pool of Power 795 systems, to increase the utility of these resources, and to enhance clients’ application availability.

Power 795 servers in a Power Flex environment are allowed to share large portions of their virtual processor and memory resources to provide capacity where it is most needed, and to best support application availability during occasional planned system maintenance activity.

A Power Flex capacity pool of systems consists of two to four Power 795 systems, each with four or more 4.0 GHz or 4.25 GHz processor books and 50% or more permanent (CUoD) processor and memory activations to support its applications. Capacity above 25% on these systems may be used as Flex Capacity Upgrade on Demand resource and re-balanced to/from another Power 795 system in the same capacity pool up to twelve times per year.

Each Power Flex system also includes a quantity of included On/Off Capacity on Demand processor days (approximately 60 days of the inactive resources on each purchased Power Flex 64/128-core system, or 960 days per 32-core processor book). These On/Off processor days are enabled via the normal Capacity on Demand resource enablement process, and may be used at a client's discretion to provide utility computing for short term projects, workload spikes or in the event an immediate maintenance activity where an Advanced Planning Event or Re-balancing request has not been requested.

Power Flex is enabled by ordering RPQ 8A1830 on each of two or more Power 795 systems that meet minimum requirements and completing the corresponding contract attachments and supplements for On/Off Capacity on Demand and Power Flex.
