Huge-page memory is a unique feature provided by HCI to optimize memory management for VMs. It increases the default memory page size from 4 KB to 2 MB for x86 and c86 VMs and 512 MB for Arm VMs, which lowers the overhead of managing memory pages, reduces the CPU resource consumption for memory page queries, and improves memory access efficiency. Huge-page memory takes effect on each individual VM and is typically used for critical VMs and VMs with Turbo mode enabled. To avoid business impacts caused by memory fragmentation, memory reclaiming is automatically disabled for VMs that have huge-page memory enabled. Huge-page memory is suitable for VMs used for memory-intensive services, such as Oracle databases and Spark big data processing services. Note: Huge-page memory requires physical memory pre-allocation, and the pre-allocated memory is not reusable. Therefore, memory overcommitment must be avoided to ensure that VMs with huge-page memory enabled can be powered on normally.
