Providing Configuration Details

Note: You should begin the commissioning process by selecting a blueprint in the Blueprint tab.

In the Cores & Memory tab, provide information in the appropriate fields and then click Next. The following table provides details about various fields in the Cores & Memory tab:

Field

Action

Partition Chassis

Choose the required partition chassis; for example, Chassis-B.

Cores

Choose the number of cores you want to assign to the partition image. The number of cores available depends on the partition chassis that you have chosen. The default value is 1.

Enable Hyper-Threading

Select the check box to enable selection of two logical processors per core.

Notes:

  • If hyperthreading is not supported by the platform or chassis, then this option is not available.

  • If you are commissioning a Red Hat Enterprise Linux 7.3 (RHEL 7.3) partition image, on the default RHEL 7.3 kernel, when processor Hyper-threading (SMT) is off, your partition will only show a single CPU core regardless of how many cores are allocated to the partition image. This is a known bug with the 3.10.0-514 kernel. If you do not wish to enable hyperthreading when commissioning the RHEL 7.3 partition image, be sure that your customer-supplied operating system image was captured from a system that was upgraded to kernel 3.10.0-514.6.1 or newer. Be sure that the kernel-devel package was also upgraded. If the kernel-devel package was not upgraded, dkms will not be able to compile the s-Par drivers and the partition image will not boot.

    For more information on creating a customer-supplied Linux operating system image, see “Creating a Customer-Supplied Linux Operating System Image” in the Installation and Getting Started Guide.

Logical Processors

Displays the number of logical processors, based on the number of cores.

Memory

Choose the memory size that you want to assign to the partition image. The default value is 2.

The memory range available depends on the partition chassis that you have chosen. The minimum value that can be chosen is 2 GB.

Notes:

  • Secure fabrics consume more memory. If you are planning to associate the partition image to a secure fabric, see Secure Fabrics and Memory Requirements for detailed information about memory usage by secure fabrics.

  • If you are assigning a larger memory, then the Fabric Manager might take longer time to commission the partition image. For example, if you have assigned a memory of 20 TB size, then the Fabric Manager might take about 30 minutes to commission the partition image.
