Copt - NEC Express5800/A2040d Configuration Manual

CONFIGURATION GUIDE

1.5 COPT

Capacity Optimization (COPT) is a function to optimize computing resources by enabling CPU cores as many
required per workload without any impact to the number of DIMM and PCI slots which depends on CPU
configuration.
When necessary, CPU core can be enabled additionally on-site.
COPT is available only with A2040d COPT supported model (NEC Express5800/A2040d (COPT)).
In order to enable CPU core, Core Activation Key should be ordered for the required number of cores.
Product Name/Description
One Core Activation Key (for Embedded)

Need to order at the same time of ordering the server. As many CPU cores as the
ordered number of the One Core Activation Key (for Embedded) are to be
enabled when the ordered server is shipped.

Up to the ordered number of the One Core Activation Key (for Embedded), CPU
cores are available for use.
One Core Activation Key (for Add-on)

The CPU core can be additionally enabled on-site by ordering the One Core
Activation Key (for Add-on).

As many Code Words as the ordered number of the One Core Activation Key (for
Add-on) are shipped, and additional CPU core can be enabled by applying the
Code Word to the server.
NOTE:

Contact to our sales representative for software supporting COPT function.

When enabling CPU core (or socket) by Core Activation Key, please purchase required software license
as appropriate

In case of using socket license based software, please enable CPU core at the CPU socket on which the
software is operating. Software license is required for the socket with at least one enabled CPU core.

Depending on the OS, the server may need to be rebooted to enable CPU cores

Remarks to use COPT under Linux environment:
- When using Fibre Channel Controller (16Gbps) [NE3390-157A/158A], need to enable enough
number of CPU cores to have 4 or more logical processors,

Remarks to use COPT under Windows environment
- Depending on the number of enabled CPU cores, PCI card to be installed is limited. Please refer for
the details to "Installation Limitations for Windows".

Remarks to use COPT under VMware environment:
- Need to purchase at least the same number of One Core Activation Key as the number of CPU
socket.
- Need to enable the same number of CPU cores among all CPUs (excluding CPUs with all cores
disabled)
<Examples of OK or NG configuration in case of 4CPU configuration>
Ex.1: OK
CPU1: 1 core enabled
CPU2: 1 core enabled
CPU3: 1 core enabled
CPU4: 1 core enabled
- Depending on the number of enabled CPU cores, PCI card to be installed is limited. Please refer for
the details to "Installation Limitations for VMware".
For the details, please refer to the latest version of "Express5800/A2040d Capacity Optimization (COPT)

User's Guide"
Default setting of Core Optimization Mode is "Decentralize", where the enabled CPU cores are

distributed to each socket equally.
