Bios Settings - Logical Memory Block Size, System Memory Page Setup, I/O adapter enlarged capacity

[priyanka-pillai97]

Use Case

As an Admin, I need to configure and manage memory on our servers to utilize their capacities more efficiently.

• Logical Memory Block Size: Enhance the managed system performance by   manually or automatically changing the logical-memory block size. The logical block size is the size of the blocks that the kernel uses to read or write files.
• System Memory Page Setup: Improve the application’s performance by setting large virtual memory page sizes of 16GB each.
• I/O adapter enlarged capacity: AllowsAllows users to set aside memory for better throughput/performance. This option controls the size of PCI memory space allocated to each PCI slot.

Questions to the community:

• Are any of these terminologies IBM specific?
• Is this setting useful to you?

These do not seem to be common BIOS settings that I have seen before. Possibly IBM specific terminologies and capabilities? I also have not seen any corresponding settings in the Redfish modeling, including the Redfish BIOS Schema which is a set of name/value pairs of BIOS Attributes.
