Sun Netra T5440 Released!

Sun has announced a Netra version of the UltraSPARC-T2 Plus architecture, the Netra T5440. The first thing I noticed about this server is that it's not the four-way UltraSPARC-T2 Plus server that has been talked about, the T5440. This Netra server is only a dual socket system. Sure it has a lot of I/O capacity for telco requirements, but it's missing two processors! It should have been called something else. I have no doubt that when the four-way non-Netra T5440 comes to market, this will cause confusion for customers. Still it is an interesting server and is heavily influenced by Telco requirements.

Sun BluePrints on LDoms and I/O

A good friend of mine at Sun, Peter Wilson has released two excellent Sun BluePrints on I/O best practices for LDoms:

• LDOMS I/O Best Practices: Data Reliability with Logical Domains
• LDOMS I/O Best Practices: Network Availability with Logical Domains

Both of these documents can help you understand the basic best practices around storage and networking for LDoms. Without a doubt these are some of the more complex areas, as there are many configuration options.

Review: SPARC Enterprise T5140/T5240 and Virtualization

I've completed my review of the T5240 with a focus on the hardware features and the ability to leverage virtualization. I think it will give people a good technical understanding of the hardware and help them brainstorm the possibilities.
