Hm.. We're likely going to be setting up the LDOMs this weekend to see how it goes. We need murphy to run apache, user logins (for web development), glassfish/tomcat and preferably backup instances of some critical services (LDAP, maybe DNS). Oh, and databases. Here's my propsed layout.. Control domain: 4GB RAM, 4VCPUs (1 physical CPU) * It seems if you want to use ZFS for storing the LDOMs, 4GB RAM for the control domain is essential. We could go lower and give more RAM to other domains if we wanted to stick with old fashioned file systems though. Apache/httpd/logins: 8GB RAM, 16 VCPUs (4 physical CPUs) Service backups: 1GB RAM, 4VCPUs (1 physical CPU) MySQL/PGSQL: 3GB RAM, 8VCPUs (2 physical CPUs) Unless I'm adding wrong, that makes 16GB of RAM and 32 VCPUs/8 physical. I'm not sure if we really want to go with ZFS for the control domain, we could just use a lesser filesystem and give more RAM to apache and maybe databases? Aside from that though... feedback welcome.. Thoughts? -Andrew On Wed, May 28, 2008 at 10:53:39AM +0100, Colm MacCarthaigh wrote:

I'm running another one too :-) but it's still got an original dapper on it.
* Ubuntu 8.04 doesn't support SPARC at all, which kinda ties back into the second point. People aren't interested in supporting it. Debian has a SPARC port that apparently supports a Niagara CPU, but there seems to be nobody (like, absolutely nobody, anywhere) using it in production. I only came across one reference to one guy using it in testing. For a morning's worth of googling, this isn't encouraging.
Yeah, it sucks :/ But using Solaris isn't so bad, handy for playing with dtrace and so on.
That's all really. Anyone have any feedback? We're completely open to suggestions on this, nothing has been decided with murphy at this point.
Sounds cool!
