How to tell if a Linux system is big endian or little endian?
CPU questions have meaningful downstream cost implications (licensing, EVC compatibility).
Byte order: echo -n I | od -to2 | head -n1 | cut -f2 -d" " | cut -c6 on Linux. Modern x86_64, ARM, and POWER are little-endian by default. For server fleets in 2026, byte order is essentially universally little-endian.

How are CPU time and CPU usage the same?
CPU questions have meaningful downstream cost implications (licensing, EVC compatibility).
Linux memory accounting: RSS = physical RAM in use, VIRT = virtual address space (includes mapped files), PSS = proportional shared pages. The "available" column in free already accounts for reclaimable cache — use that as your real free-RAM number.
HBA firmware mode: IT-mode (pass-through) is required for software RAID (ZFS, vSAN, Ceph). RAID-mode for hardware RAID. LSI/Broadcom 9300/9400/9500 series HBAs flash between modes cleanly.
