Sun's Commitment to Open Standards
One of the hats I wear for Sun is to serve on the DMTF Board of Directors as Sun's representative. The DMTF recently had a Board election (for which they just released results) - they do this every two years. Sun was re-elected to the board for another 4 years. The DMTF is best known for its Common Information Model (CIM) used throughout the industry as the information model underlying much of the resource instrumentation being deployed.
I have blogged here in the past about some of the work going on such as Policy, WS-CIM and WS-Management. Some of the other work in progress that bears watching include the popular initiatives with catchy names: DASH and SMASH. These are profiles and modeling work for managing Desktop/Mobile and Servers respectively. Also, there is work going on for Virtualization, Partitioning and Clustering that is being carefully watched for its promise to standardize the management of virtualization.
Sun always has and continues to incorporate these standards into its products, especially in the storage industry where SMI-S has taken root and continues to flourish. Sun is a leader in not only adopting, but also the development of standards such as those of the DMTF. As a result, customers get true interoperability and vendor choice in best of breed products.
