My favorite ones from last week...

Selected Sun product conversations in blogosphere during last week:

1. Solaris Express - Kaiwai's Blog, 7/13
Kaiwai recently installed Solaris Express Community Edition and hopes VMWare will be ported to Solaris x86 in the near future.

2. Solaris on Intel is Telecoms' Grade - BladeWatch, 7/17
Martin highlights the recent availability of Solaris on Intel-based rack and blade servers and says it is "great news, and brings more choice for the telecommunications market to choose which platforms they use for their Solaris based systems."

3. Energy Efficient Computer Labs and How IT Can Work to Remove Roadblocks - Mikael Gueck's Little Island of Excitement, 7/13
Mikael discussed the idea of creating a more energy efficient computer lab and identified Sun Ray Client technology as a key solution. He mentioned Sun Ray as an alternative to off-the-shelf computers that "are becoming much more powerful than necessary." Mikael went on to say, "The Sun Ray client connects to your monitor, mouse, USB and Ethernet, and lets you run 10 lab desktop sessions on one computer.13 It's stateless, all the processing happens on the other end. If the Sun Ray desktop client breaks, you just replace it, and you're back up and running where you were before the break."

4. Sun LDOMs on CoolThreads Servers - Outside the Asylum, 7/12
Daniel recently setup LDOMs on a T2000 and advises following the release notes.

How-to articles on Solaris LDOM software from "Sparks and White Noise"

Octave Orgeron, a Solaris/OpenSolaris enthusiast writing under the name "Sparks and White Noise," has been posting a series of very useful articles on Solaris Logical Domain Management Software (LDOM).

The first introduction post describes Logical Domains as, "discrete instances of the Solaris OE running independently within a virtualized environment." The entry goes on to discuss the four types of LDOM's that can be created including Control Domain, Service Domain, I/O Domain and Guest Domain. He mentions that there are two service domains in the Sun Fire T2000, and then distinguishes the the I/O domain is different in that, "none of its devices or services are virtualized for guest domains."

His second post is on installing LDOM. It describes the necessary hardware for the initial installation of the firmware, and mentions the two methods for this installation. The post then relates how to install the LDOM software as the control domain.

In his third post, Octave provides steps for configuring the control domain and reminds users that when all 32 vcpu's and memory are assigned to the domain, "we must free up these resoureces and create the basic infrastructure to support guest domains."

Octave plans to discuss the creation of guest domains in his next post.

Thanks very much Octave for these very helpful how-to articles!!!

Update: The article on building a guest domain is now posted as well.
