Configure Elastic Computing

The elastic computing feature allows you to maximize the performance of your server for your specific workload at runtime. Oracle servers with the elastic computing capability use an Intel Xeon® E7-8895v2 processor that combines the capabilities of multiple other Intel processors into one This allows you to adjust the core counts and processor speeds dynamically at runtime, as often as you need.

Note -  Elastic computing is supported on Sun Server X4-4 and Sun Server X4-8. For best performance, use the latest Oracle Solaris operating system or the latest version of Oracle Linux with UEK kernel.

During some periods, your enterprise applications or databases might benefit from having as many cores as possible, while at other times having fewer but faster cores results in greater overall performance. Rather than requiring you to pre-select a processor that is optimized for only one fixed workload, Oracle servers with the Intel Xeon E7-8895 v2 processor allow you to dynamically adjust to your enterprise or database workload at runtime to enable maximum performance at all times.

Oracle firmware and operating systems have been extended to allow you to take advantage of the elastic capabilities of the Intel Xeon E7-8895v2 processor by efficiently handling the processor state changes required to vary the core count and maximum frequency of the processor at runtime.

The elastic computing capability is simple to configure. As you deactivate cores, the remaining cores are able to achieve higher maximum frequencies. You can adjust the number of active cores at any time and as often as desired.
