As I've been told it was named SVR5 to mark inclusion of enterprise-level features (and yes, for marketing reasons): - better CPU scalability with modular support for different platforms (initially UW7 was up to 8 CPUs well and 12 CPUs so-so, now up to 16 CPUs well) - support for over 4GB of memory - support for large areas of shared memory attached to great many processes - multi-path I/O support (a disk can be connected to 2 or more SCSI buses) - integrated volume manager (from Veritas, terrible thing, and often broken) - hot-swappable disks - hot-pluggable PCI cards - high availablilty clustering (Reliant from Veritas, terrible thing, and sometimes broken) Internally it had significant extensions in the multiprocessor support, memory and re-designed I/O subsystem. -SB To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
