No comment just another good article on this overall subject.

DBA and Sysadmin: Linux
Introduction to Linux Cluster Filesystems
by Sheryl Calish
Cluster filesystems complement the database cluster facilities in Oracle RAC in
various ways. Here's how they compare.

Well...I should have spent a minute more reading the doc I referred to.
This is not ambiguous at all!
And sadly I *suspect* that if one opens a TAR and tells Oracle Support they run
on Polyserve...Oracle Support will quickly tell them "good bye",...no?

What filesystems are supported for Oracle on Linux?
Supported filesystems include Oracle Automatic Storage Management (ASM), ext3
(with O_SYNC), NFS, OCFS, ReiserFS, and raw. XFS is not supported.

Subject: RE: polyserve and oracle 10g
I learned a lot about Oracle "Unbreakable Linux" from Kevin's comments, however
I'm not sure I'm any more clear if Oracle generically supports Oracle (on
Linux,) on Polyserve?
When I say "generic" I don't mean the "Unbreakable Linux" part, when Oracle
Corp will *fix* Linux if Oracle wont run on it...no, I mean, I can open a TAR
that is NOT and Linux issue but 100% an Oracle issue and Oracle Support will
help me if my Database is running on (on Linux,) on Polyserve?
Often Oracle is not very clear and it depends on the platform. In the Intel
space Oracle seems very specific about the *entire* hardware/software stack,
while on big UNIX (AIX, HP, SUN) they say; "Oracle supports Oracle version abc
on UNIX OS version xyz, and if your UNIX OS version xyz supports a piece of
hardware for software then you covered and will not be turned away by Oracle
Support.
Is this matter of 3rd party certification with Oracle? I *assume* this exists
and has Polyserve made any effort to partner with or had their products
certified by Oracle?
For example, if I my database lives on NetApp-NFS, Oracle Support will support
my TAR.
However, if I tell Oracle Support that my database lives on an Intel NFS box I
built myself...they will likely send me packing and that they don't support
Oracle database over NFS.
Which side of the "support line" does Polyserve fail?
Will Oracle Support me if I run the database on *any* filesystem that will run
on Linux?
Maybe this is the answer;

>> Oracle will continue to support Oracle products on the certified Linux

I bounced the initial post off Kevin Closson at Polyserve, and he
replied as follows:
<quote>
>>i've seen some references that oracle does not certify oracle=20

>>"Unbreakable Linux" is therefore not provided. i believe this=20
>>is because polyserve requires a custom kernel to run.
This is a long answer to a topic that is actually wider than
PolyServe. The key is knowing what "Unbreakable Linux" is.
PolyServe contains Kernel Loadable Modules (KLM). Just loading a=20
non-open-source KLM into the kernel voids "Unbreakable Linux".=20
That includes certain Fiber Channel HBA drivers, certain=20
MPIO drivers and so on. The only software allowed
to be closed source is Oracle for "Unbreakable Linux".=20
PolyServe is not going to open source our products. Like Oracle,
we have a great deal of proprietary value add and a business model
that does not favor open sourcing. The value-add is exactly why HP=20
and Novell resell (and OEM in the case of HP) PolyServe - and provide
support=20
for it along with Linux. Not all problems can be solved with Open
Source.
That is the very reason customers are still choosing Oracle instead
of MySQL for certain IT needs.
So the answer to this question is to first understand "Unbreakable
Linux".=20
The following points are based on quotes from this URL:
http://www.oracle.com/technology/tech/linux/htdocs/oracleonlinux_faq.html#6
1. Unbreakable Linux is support for the Operating System.
"Oracle customers running RHEL, SLES or Asianux, can call Oracle=20
directly for any Oracle or OS issue. Oracle will diagnose the issue=20
and will work with the OS partner to address the operating system=20
issue as needed."
2. Even with Unbreakable, customers still need OS support from the OS
provider.
"customers must have a current support contract in place with Oracle.=20
In addition, Novell and Asianux customers must maintain current support=20
contracts with those distributors, and Red Hat customers must maintain=20
a Standard or Premium support contract with Red Hat to be eligible for=20
Unbreakable Support."
3. Choosing to deploy outside the "Unbreakable" model does not render
Oracle products unsupported
"If a customer recompiles the kernel or uses third-party software that
modifies=20
the Linux kernel, they are no longer eligible for Unbreakable Linux
Support=20
and can't receive direct Linux OS technical support from Oracle. In
these=20
cases, Oracle will continue to support Oracle products on the certified
Linux=20
distributions."
The PolyServe website contains a good deal of Oracle specific content.
The=20
value propositions are all outlined in solution briefs stored there.
