Memory Module Configuration; Enable Software Guard Extensions (Sgx); Raid Configuration - Lenovo ThinkSystem SD530 V3 System Configuration Manual

You can configure the management processor for the server through the Lenovo XClarity Controller Web
interface, the command-line interface, or Redfish API.
For information about configuring the server using Lenovo XClarity Controller, see:
"Configuring the Server" section in the XCC documentation compatible with your server at

Memory module configuration

Memory performance depends on several variables, such as memory mode, memory speed, memory ranks,
memory population and processor.
Information about optimizing memory performance and configuring memory is available at the Lenovo Press
website:

In addition, you can take advantage of a memory configurator, which is available at the following site:

Enable Software Guard Extensions (SGX)

Intel ® Software Guard Extensions (Intel
includes only the internals of the CPU package, and leaves the DRAM untrusted.
Complete the following steps to enable SGX.
Step 1. Make sure to refer to "Memory module installation rules and order" section in the User Guide or
Hardware Maintenance Guide, which specifies whether your sever supports SGX and lists the
memory module population sequence for SGX configuration. (DIMM configuration must be at least
8 DIMMs per socket to support SGX.)
Step 2. Restart the system. Before the operating system starts up, press the key specified in the on-screen
instructions to enter the Setup Utility. (For more information, see the "Startup" section in the LXPM
documentation compatible with your server at
Go to System settings ➙ Processors ➙ UMA-Based Clustering and disable the option.
Step 3.
Go to System settings ➙ Processors ➙ Total Memory Encryption (TME) and enable the option.
Step 4.
Save the changes, then go to System settings ➙ Processors ➙ SW Guard Extension (SGX) and
Step 5.
enable the option.

RAID configuration

Using a Redundant Array of Independent Disks (RAID) to store data remains one of the most common and
cost-efficient methods to increase server's storage performance, availability, and capacity.
RAID increases performance by allowing multiple drives to process I/O requests simultaneously. RAID can
also prevent data loss in case of a drive failure by reconstructing (or rebuilding) the missing data from the
failed drive using the data from the remaining drives.
RAID array (also known as RAID drive group) is a group of multiple physical drives that uses a certain
common method to distribute data across the drives. A virtual drive (also known as virtual disk or logical
drive) is a partition in the drive group that is made up of contiguous data segments on the drives. Virtual drive
