The Dell EMC Ready Architecture for Red Hat OpenStack Platform version 16.1 provides the ability to enable hugepage support on the compute nodes at the core or the edge site(s) in the solution.
If a program or a VM instance uses large data structures, then the use of small (i.e. 4 KB) pages leads to the fragmentation of those data structures and loss of data locality. With Hugepages of sizes 2 MB and 1 GB, programs and VM instances can improve data locality, thus leading to a higher performing and lower latency architecture.
