(1) Intel 32-bit Systems in the tables above.
(2) AMD64, Intel EM64T 64-bit Systems in the tables above.
(3) Multi-core and/or hyperthreading CPUs count as a single CPU in the table above.
(4) Update 7 is available as of August 1, 2008
(5) Limit low because the "hugemem" kernel is not available
(6) Update 4 is available as of April, 2010
(7) Unbreakable Enterprise Kernel for x86_64 is available over Oracle Linux 5.5 and higher
(8) With latest update level
(9) With Oracle Linux 6 the default kernel is Unbreakable Enterprise Kernel on x86_64 and RHEL compatible kernel with x86 (32-bit). The limits are provided based on that.
(10) AMD64 / Intel64: On those kernels larger memory can be handled with Intel CPUs
(11) Unbreakable Enterprise Kernel for x86 is available from Oracle Linux 5.7 and higher
(12) The theoretical upper limit is 5120 logical CPUs.
(13) Although the minimum disk space required for installation is 1GB, a minimum of 5 GB is recommended.
