Darren, don't go there, I'm a grown man, but don't mind if you want to call
me a cutie... my wife does it and it's fine... ;-)

Anyway, as I said, it was a mistake and unintentional, but at least, as you
said, it's a "good" junk"...
Sorry again.

Re: [ubuntu-cloud] Ziv Leyes invited you to Dropbox

[Ziv Leyes]

I'm sorry, it was a mistake, I let the referral feature take contacts from
my gmail and I selected my friends and deselected all the irrelevant others,
but by mistake I may have missed some irrelevant contacts and received this
message that was intended only for my friends.
Again, my apologies, I'm not a spammer and I hate spam myself. It won't
happen again, sorry!

Re: [ubuntu-cloud] Hardware recommendations for UEC

[Ziv Leyes]

Hi Ahmad,
Thanks for your answer.
I know the general prerequisites and hardware requirements from the
links you've mentioned.
Given the fact I'm limited to use ONLY IBM servers, I was hoping to a more
specific answer about a certain IBM recommended server model, perhaps based
on self experience of some people in the community.
The servers have a lot of variants, such as how much RAM, which exact CPU
model, hardisk type of controllers (SCSI, SAS), etc.
Also, if I want to run a few virtual servers, how many NIC do I need to
have? I know I might need more than one because not all the machines are
connected to the same network domains.
Thanks,
Ziv

[ubuntu-cloud] Hardware recommendations for UEC

[Ziv Leyes]

Hi all,
We're interested to start using UEC on our company.
My only limitation is my company works with a hardware provider that
supplies only IBM servers, so I need some specific recommendations about
what could be a good pair of servers to start installing an Ubuntu cloud.
We're using a few of the last models such as x3250 or x3550 all based on
Xeon CPUs and such, but they all have different variations on the hardware
list.
I want to know what would be the recommended specs for such a server, I was
thinking on having one of them with bigger storage for the Walrus, perhaps
you would recommend to get a third server only for storage?
In general, what could be a nice setup of a couple of IBM servers if you can
be more specific?
Thanks in advance,
Ziv

Re: [ubuntu-cloud] UEC Single Point of failure

[Ziv Leyes]

Hi Björn,
I guess you might be confused due to subtle semantics, it doesn't say it
SHOULD be 1 CC, it says at least, the minimal requirement (not recommended
for production environments) is to have 2 machines, but the more, the
merrier.
Please take a look at the different possible topologies in the link below:
https://help.ubuntu.com/community/UEC/Topologies

Hope this helps,
Ziv

Re: [ubuntu-cloud] Questiong on setup of cluster and node

[Ziv Leyes]

Hi Stephen,
I'm also only a user, and I'm trying to help based on my own knowledge, so
don't take my answers so official, I might be wrong here and there and I'll
be happy if someone corrects me when I'm wrong.

UEC (ubuntu enterprise cloud) IS a VM platform, it runs KVM in the
background, the minnimal recommendation of two bare metal machines is for
running it at a basic environment, one machine will be the cloud controller,
cluster controller and storage controller, the other machine will be a node
that runs node controller, one node minimum is required, but you can add as
much more nodes as you can.
Look at this installation guide:
https://help.ubuntu.com/10.04/serverguide/C/uec.html

The cloud can be fully managed via command line, but if you find that
difficult there are a few graphical options, one is free and included in the
installation, it's called Eucalyptus, the other one is Landscape, but you
need to pay for an account to Cannonical. There are a few others but I don't
know them.

Once you have a cloud running on this minimum of two machines, you can
create virtual hosts and run on them whatever you want.

If what you're looking for is a way to virtualize one OS in within another,
then all you need is to install whatever OS you prefer and run KVM or
VirtualBox inside and create VMs, but if what you need is a bunch of VMs and
you want to manage them wisely and get the most out of the whole hardware
put together, then you need to think about cloud computing.
The main goal of the cloud computing is a re-use of existing resources,
given the fact that when you run a server it doesn't use the whole of it
resources and most of the time the server might be idle, those resources
could be used by other services, when you put for example three nodes and
every one has a 2Ghz dual core cpu with 4GB RAM it means you have a
virtually bigger server of 6Ghz dual core with 12GB of RAM, now you can run
6 "smaller" virtual servers of 1Ghz CPU and 2 GB RAM, given that it will be
enough for running what you need.
But this is only a simple example, things in the IT world can be more
complex...

I hope this helps you.
And as I said, if someone thinks I'm mistaking, please correct me.
Regards,
Ziv

Re: [ubuntu-cloud] Questiong on setup of cluster and node

[Ziv Leyes]

Hi,
I think you should give it a try the way it's supposed to be instead of
giving up.
The ubuntu cloud is meant to be a platform that runs VMs, so what you're
trying to do is to run a VM platform from within a VM host!
As a no so related allegory, is like installing WindowsXP, then run
VirtualBox, create a new machine, install Win7 and install VirtualBox inside
it, and then expect that this VirtualBox will satisfy your needs...
