I've just started working on the rac 10g lab(at my house). I've cleaned
all of the oracle 9i stuff off, will let everyone know what happens(soon
as i can get some more time to work on it, currently spending my free
time studying to upgrade my ham radio license).

Yes. Oracle RAC is so called "shared disk system" (in contrast to
share-nothing systems), which means that it uses disks shared by two
computers. Access to the disk is synchronized by DLM (= Distributed
Lock Manager), which is a part of oracle RAC. Also, on Linux, oracle
delivers the OS mechanism for two nodes to communicate over the
private Ethernet connection.
If so, can someone recommend a scaleable bit of hardware (preferable
Dell) that I can use with 2+ nodes to support the database files of
the RAC.
He is a distinguished member of this group and he used to have a good
web page at http://www.oracle-dba.com, but there is not much there
these days.
I dunno about the exact HW specification, but Joe Testa once wrote
that he was working on RAC.
If not, can someone please enlighten me.
I specialized in enlightenment.
