Escala technology: Power on Demand

Pay for growth only when you need it

Power on Demand is an offer 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 sudden 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 higher granularity: Activation of only 1 processor or 1GB memory is now possible
• 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 Escala PL1650, PL3250 and PL6450 as new orders or as upgrades.

Three ways to apply Power On Demand

• Permanent activation of processors or memory in case of:
  • Increasing application response times,
  • System is regularly saturated,
  • Installation of a new application is planned.
  
  
  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.
  The activation granularity is 1 processor and 1GB for memory.
  When you want to activate resources, place an order with your sales representative or on-line through the web pages. You will receive an encrypted key by e-mail.
  
  
• Temporary activation of resources, ideal solution for:
  • Applications with performance peaks limited to specific times,
  • High availability / disaster recovery installations.
    
    
  Each block entitles usage of 30 processor days. The inactive processors are assigned to the shared processor pool. The server then automatically manages the workload and charges the processor day account when the permanent processor workload exceeds 100%. Processor usage is measured in one day increments.
  Temporary activation requires AIX 5.3 and virtualization features.
  
  

• Trial, free test drive for 100% processors and 100% memory.
  • Immediately after system installation, in order to test once the performance impact of using the ‘inactive’ resources for the customers individual application,
  • At any chosen time to overcome the first unexpected performance peak or takeover situation.
    
    
  The trial-period lasts for the duration of 30 consecutive days and can be activated with the encrypted key delivered with the initial system.
