Escala Power on Demand
Pay for growth only when you need it

Power on Demand is an option that allows you to add resources as they are needed. Pre-installed, but inactive CPU and memory resources can be activated to respond economically to unpredictable workload peaks, additional workloads from other servers or steadily growing workloads.
Power on demand adds no administrative costs, only advantages and higher flexibility.
-
No more wasted money on over-sizing: New servers can be tailored to the exact performance predictions
- No more risk of under-sizing: Additional resources are inside the system and can be activated immediately
-
Cost saving through small granularity: Activation of only 1 processor or 1GB memory
-
Ability to use temporary extra capacity on a trial basis or to support operations in case of exceptional needs
-
Higher Reliability: automatic replacement of failing components (build-in spare parts)
- No waiting for shipment: Resources are ‘in-place’ and can be activated immediately when needed
- No interruption of services levels during upgrade: Thanks to ESCALA PL’s dynamic partitioning capability (DLPAR)
- Power On Demand is available on selected POWER6™ and POWER5™ Escala servers as new orders or as add-ons.
Different types of Power On Demand on selected Escala servers
- Permanent activation of processors or memory in case of:
-
Increasing application response times,
-
System is regularly saturated,
- new needs : new application
- deployment, more users…
Power On Demand features enable you to start small, saving on initial acquisition costs, and then increase your processing capacity without disrupting your application service levels. Power On Demand offers smooth activation with DLPAR and no obligation to purchase inactive resources. Processors can be activated in increments of 1 processor, while memory can be activated in increments of 1 GB.
- Temporary activation of resources, ideal solution for:
-
Applications with short and unpredictable workloads spikes,
-
Seasonal activities
-
High availability / disaster recovery installations.
Different Power On Demand options allow temporary activation of resources:
The On/Off Power On Demand is used to fully activate a resource temporarily to cover for the demands of business peaks. It is user- managed and available for both processors and memory. The system monitors the amount and duration of the activations.
The Utility Power on Demand, for Escala POWER6™ enterprise servers, is only available for processors. Activations are automatically managed by the server and are measured in processor minute increments.
