Custom hardware support

While many operating systems provide HA support in a hardware-specific way (e.g., via PCI Hot Plug), QNX Neutrino isn't tied to PCI. Your particular HA system may be built on a custom chassis, in which case an OS that offers a PCI-based HA “solution” may not address your needs at all.

Note: QNX Software Systems is an actively contributing member of the Service Availability Forum (, an industry body dedicated to developing open, industry-standard specifications for building HA systems.
