An interesting problem would be to use reasonably powerful
Lo all,
I've pinged Ellis a mail with a couple of specific Q's but I wondered if
anyone here has any experience with disco (http://discoproject.org/).
I'm still in the early days of testing but would be interested to hear
if anyone has an installation running at scale or in anger.
Thanks

Don't post something ridicioulous like that.
That 64MB they use of course as with infiniband shipping a message of
64MB wil get you the full bandwidth over the network
and keep number of messages down and infiniband doesn't work at your
laptop.

Basically my idea is to setup a green self sustaining data center. My hang
up is finding investors. Where I am electricity is super expensive and the
costs are passed onto the clients hosting with the current Local data
centers.
Would be great if there were some investors on this list, but I think

There is Clustered LVM but I dont think this is what your looking for. CLVM
allows you to have a shared storage target such as an iSCSI box and give
one LV to one box and another LV to another box
Interesting indeed. Does LVM span across multiple storage servers?
That is another issue and im not trying to open up a can of worms but what
is the advantage of using KVM over xen or even citrix xen server

Sure. With virtualisation by KVM. (although not sure about the windows and
mac) Maybe VirtualBox?
I'm currently designing a cloud computing platform that uses NFS for the
worker virtual machines (databases and webservers etc) and the local
storage can be exported using gluster or whatever.
Say if
Sadly I have no experience in a cluster environment :( I do have my old
laptop and hopefully have a 2nd one soon. Is it possible to have a mixed

someon
not as efficient as gluster I would venture.
