CentOS - Dec 2010 - Antwort: MegaRAID SAS 9280-24i4e -- Centos support.

Timo,
Its interesting, I am presently attending a conference in NYC and in one
of the tables I saw the redhat vendor. My first question to them was "
What do you think about centos", they reply "You are using a
distribution without support and that is prompt to failure..." I don't
think this is an accurate statement is it? Anyway to make the story
short, they keep telling how bad centos is for our datacenter and that I
should consider adopting redhat which is more "robust", offers
"virtualization" and nearly real-time support for its customers. I
didn't go the extra mile to ask for pricing but would appreciate  your
input about what they said about centos. Lisandro

You're welcome.

Ah, and welcome to the world of proprietary drivers. This is something
that the OpenBSD guys do right: They ignore them. ;)

CentOS == RedHat.
CentOS has every bug that RedHat has.
CentOS has every bug fix that RedHat has. 
When RedHat rolls out a new version (e.g. RHEL6.0) there is a lag of a
few months rolling out the CentOS release of the same version; for bug
fixes the lag is a few days.
 
So, the price of RedHat is money, the price for CentOS is patience.
The product sold by RedHat is support, the product 'sold by' CentOS is
self-support.
The relative value of the two arises from your ability to support your
systems.

No. It's not. CentOS lacks a number of the clustering features
available to RHEL, which are burdened by non-open-source licenses or
patents. RHEL is also investing considerable money in development,
which is helpful to support, especially if you need bleeding edge
drivers (as someone just needed here for a new SAS controller), and
for which you'd have to hope Google has an answer or you find someone
like, well, *me* to bundle you a new version nad fix it for you.

CentOS is also much, much faster to update once the updates are
published, and to use OS image building tools like "mock", because of
the distributed source repository rather than the burdensome DRM
involved in the RHN registration tools. CentOS also publishes kernels
with NTFS and similar support that RHEL has been leery of.

And to cover your ass.

Thank you Nico, i think at this point Centos will be my next testing platform.
Sounds good so far.

The centos has support for this controller by default, I just had to do
some tweaking in the actual controller in order to see the virtual
console. I think it was my mistake all along to get this thing going, my
box is flying using Vmware ESX 4.1, the nxt step is to configure centos,
redhat, windows 2008 R2, debian, ubuntu and all the other goodies I am
testing, opps almost forgot Solaris 11 express and Opensolaris.  Testing
time for me. Lisandro

I don't think LSI has proprietary drivers.. they provide the sources,
and also pre-compiled driver disks for some linux distros.

I assume RHEL/CentOS 5.5 does not (yet) contain a driver for that HBA,
so they're making it easier to use that HBA.

In the future (maybe in RHEL/CentOS 5.6) the driver is probably included
in the distro, out-of-the-box.
