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.
