ServerNet (Tandem)

ServerNet is a switched fabric communications link primarily used in proprietary computers made by Tandem Computers, Compaq, and HP.

Its features include good scalability, clean fault containment, error detection and failover. The ServerNet architecture specification defines a connection between nodes, either processor or high performance I/O nodes such as storage devices.

History

Tandem Computers developed the original ServerNet architecture and protocols for use in its own proprietary computer systems starting in 1992, and released the first ServerNet systems in 1995. Early attempts to license the technology and interface chips to other companies failed, due in part to a disconnect between the culture of selling complete hardware / software / middleware computer systems and that needed for selling and supporting chips and licensing technology. A follow-on development effort ported the Virtual Interface Architecture to ServerNet with PCI interface boards connecting personal computers. Infiniband directly inherited many ServerNet features. After 25 years, systems still ship today based on the ServerNet architecture.

gollark: Not unsafe in the sense that it'll do undefined behaviour probably, just that you can't statically be sure it only contains the type you want.
gollark: It's a wildly unsafe and slow "generic", and you can write fast code with generics. More so than if you have to unsafely typecast any time you want a data structure other than the 3 built-in ones.
gollark: (I know they seem to be working on them now, but it's after years of denying they were necessary or good)
gollark: Go as in golang? In which case, mandatory lol no generics.
gollark: Also sort of various mesh overlay network things like yggdrasil/cjdns.
