Means a single Intel Xeon processor. One CPU socket can have several
cores. With Express5800/A2040, up to 4 CPU sockets can be installed in
the server.
Core portion of CPU that performs arithmetic processing and others. One
or more cores can exist in CPU socket.
Means physical mounting position of a CPU socket in the server. The
number from No. 1 to No. 4 is assigned for every CPU socket.
Means the processor where OS actually executes task and threads. When
Hyper-Threading feature is enabled, two logical processors exist in one
CPU core. When Hyper-Threading feature is disabled, only one logical
processor exists in one CPU core.
