Re: Compaq launches Open SSI Cluster Projects

[David Brower <David.Brower@oracle.com>]

They -have- developed in a linux vacuum; this is the Tandem/NonStop/SCO
Unix cluster stuff, pretty much as deployed on that platform.

Personally, I am more interested in the CI part of the project, which
along with the IBM DLM would provide a reasonable GFS platform.  It seems
it would get together faster than GFS-on-DLM-on-heartbeat would.

I'm less into in the very-large scope SSI work, maybe because I don't 
understand the implications of the failure domains.  It has appeared to me
before that failure of a node is likely to have deeper ripples in the SSI 
scheme than it does in clusters with less tightly coupled nodes.  And it
is all very intrusive in ways one wonders if Linus would ever accept.  Its
a noble attempt, but it's gonna be a lot harder to accept.

In a perfect world, many of the components would plug together; I don't know
how the CI stuff maps into the heartbeat model.
