Subject: [9fans] raid on plan9?
Date: Wed, 7 May 2003 15:46:00 -0600 [thread overview]
Message-ID: <Pine.LNX.4.44.0305071539480.2948-100000@fbsd.cpsc.ucalgary.ca> (raw)
i can't find any information on the wiki about supported raid controllers
under plan9. i can see from urjc.es' site that nemo is running a raid
venti/fossil configuration, but no controller is listed..
can you give me more information about the various raids you use: what
controllers, types of raid and possibly gotchas I should be aware of...
i promise to update the wiki afterwards :)
also, i should assume that there is no driver for the 3COM 3C940 Gigabit
cards, since nobody said they've used one, right?
the raid controller i have in mind comes with asus Asus P4C800 and is a
Promise 20378.

ps (offtopic) interesting thing, the antares 5070 is somewhat based on
plan9, apparently:
The Antares 5070 is a high performance, versatile, yet relatively
inexpensive host based RAID controller. Its embedded operating
system (K9 kernel) is modelled on the Plan 9 operating system
whose design is discussed in several papers from AT&T (see the
"Further Reading" section). K9 is a kernel targeted at embedded
controllers of small to medium complexity (e.g. ISDN-ethernet
bridges, RAID controllers, etc). It supports multiple lightweight
processes (i.e. without memory management) on a single CPU
with a non-pre-emptive scheduler. Device driver architecture is
based on Plan 9 (and Unix SVR4) streams. Concurrency control
mechanisms include semaphores and signals.
