Capacity on Demand Implementation Strategies

IBM Capacity on Demand IBM Power Systems Capacity on Demand is one of the best ways to provide your enterprise with a capacity for limitless growth without the downtime involved in constant downtime for upgrades and for moving applications. Even with VM technologies, you’re going to find some limitations as to how fast a system can grow in response to demand.

Capacity on Demand for IBM Power Systems allows you to activate dormant resources without having to bring a system or an application down. It lets you do this on a permanent or a temporary basis, and it does it fast.

Depending on the availability of capital resources and your specific configuration needs, there are a number of implementation strategies for Capacity on Demand that you can consider:

1.    On/Off Capacity on Demand. This is a temporary way to address short-term capacity needs. It provides you with a limited amount of memory and processor activation to be used during peak times. Whether your business experiences seasonal increases in demand, has special needs at the end of the quarter or other priods or whether you expect increased need during a promotional period, On/Off may be right for you. With On/Off CoD, you get an enablement code that will let your system operator make requests for increased memory or processor capacity. There are pre-pay options for On/Off CoD as well as post-pay options.

2.    Permanent Capacity Upgrade on Demand. Under this configuration, you have a more permanent solution to your capacity needs. You bring memory and processors online in a dynamic fashion without having to interrupt systems, applications or partitions. As your workload increases and as your processor needs increase, you simply place an order to activate additional features. There is no hardware shipping to wait for or install. You simply retrieve an encrypted code that will unlock the capacity that you need.

3.    Utility Capacity on Demand. If you have short workload spikes and you need an automated way to make sure that your servers perform, Utility CoD may be right for you. It gives you automated use of processors from the shared pool. Your usage is measured in terms of processor minutes, rather than in increased processing power or increased memory.

4.    Trial Capacity on Demand. Sometimes, you aren’t entirely certain if you need extra processor capacity or not. In this kind of situation, you can implement additional processor cores or memory for a trial period to see if the additional capacity meets your needs in the way you think it will. You can turn on additional cores or memory for a certain number of activations, giving you a measurable period in which to compare. From there, you can make a purchase of permanent processor activations as needed.

5.    Trial Active Memory Expansion. On POWER7 servers, Active Memory Expansion lets you go beyond the limits of the physical memory on your server. This means that a server that was previously constrained by memory can now do more work. Trial Active Memory Expansion operates by utilizing CPU resources to compress and decompress the partition’s data. You can activate this solution for 60 days at no cost to evaluate how the expansion works for you.
