Uptime and stability are excellent; it’s the OS you set and forget. LVM + Serviceguard make storage and failover predictable. Admin tooling (SMH/SAM, swinstall, kctune) keeps patching and tuning controlled. Security (RBAC, Trusted System) is straightforward to lock down. Rock‑solid UNIX for mission‑critical workloads. Not flashy however, just dependable. Review collected by and hosted on G2.com.
Hardware ties (PA‑RISC/Integrity) and licensing costs limit flexibility. Modern tooling/ecosystem is thin, containers and cloud‑native workflows aren’t first‑class.
Fewer community packages; upgrades require careful planning. Review collected by and hosted on G2.com.
