In the Lustre Manual 5.5.2.1 section, the examples mentioned: *For example, for a single MDT on an MDS with 1,024 compute nodes, 12 interactive login nodes, and a* *20 million file working set (of which 9 million files are cached on the clients at one time):* *Operating system overhead = 4096 MB (RHEL8)* *File system journal = 4096 MB* *1024 * 32-core clients * 256 files/core * 2KB = 16384 MB* *12 interactive clients * 100,000 files * 2KB = 2400 MB* *20 million file working set * 1.5KB/file = 30720 MB*
I'm curious, how were the two numbers, 256 files/core and 100,000 files, determined? Why?
