Capacity on Demand allows you to easily activate processors and memory without disruption to your operations, paying for the increased capacity as your needs grow. The following programs are available:
Capacity Upgrade on Demand (permanent)
Capacity Upgrade on Demand provides the ability to bring new capacity on-line quickly and easily. Processors and memory can be activated dynamically without interrupting system or partition operations. Processors can be activated in increments of 1 processor, while memory can be activated in increments of 1 GB. As your workload demands require more processing power, you can activate inactive processors or memory simply by placing an order for an activation feature. You can retrieve, over the Internet an electronically encrypted activation code that unlocks the desired amount of capacity. There is no hardware to ship and install, and no additional contract is required.
On/Off Capacity on Demand (temporary)
On/Off CoD provides short-term processor and memory activation capability for fluctuating peak processing requirements such as seasonal activity, period-end or special promotions. When you order an On/Off CoD feature, you receive an enablement code that allows a system operator to make requests for additional processor and memory capacity in increments of 1 processor day or 1 GB memory day. The system monitors the amount and duration of the activations. Both prepay and post-pay options are available.
Utility Capacity on Demand
Utility CoD provides automated use of on demand processors from the shared processor pool for short-term workloads on IBM POWER6™ processor-based systems. Utility CoD is for customers with unpredictable, short workload spikes who need an automated and affordable way to help assure adequate server performance is available as needed. Usage is measured in processor minute increments.
Trial Capacity on Demand
Trial Capacity on Demand provides the flexibility to evaluate how additional resources will affect system workloads. A standard request is easily made for a set number of processor core activations and/or a set amount of memory activations. The standard requests can be made after system installation and again after each purchase of permanent processor activation. POWER5 and POWER6 servers except the POWER6 595 can activate up to 2 processor cores and/or up to 4 GB of memory. POWER7 and the POWER6 595 can activated up to 8 processor cores and/or up to 64 GB of memory.
An exception request can be made one time, over the life of the machine and enables all available processor cores or memory.
Both standard and exception requests are available at no additional charge. See what additional power is waiting for you
Trial Active Memory Expansion
Active Memory Expansion can allow a POWER7 server to expand beyond the physical memory limits of the server for an AIX 6.1 partition. Thus a previously memory constrained server can do more work. The degree of expansion depends on how compressible is the partition's data and on having additional CPU resource for the compression/decompression. A one-time, no-charge 60-day trial allows the specific expansion and CPU usage to be evaluated.
