After hearing and reading misinformed commentary on Microsoft's source code leak elsewhere, I was pleased to be reminded that the Register has clueful writers. One of them, Ashlee Vance, reported on Solaris 10. I've had a soft spot for Solaris since 1997, when I first used it as an Air Force lieutenant. I've only just started playing with Solaris 8 on my Ultra 30, never mind Solaris 9. (Incidentally, major kudos to Sun for providing easy access to these earlier versions with intuitive URLs!)
According to Ms. Vance:
"One of the major new additions to Solaris 10 is the N1 Grid Containers product. Sun has gone through some name changes with the product since we first reported on the technology, but the premise of the software has stayed the same. The containers are Sun's answer to logical partitions (LPARs) on AIX and HP-UX and the virtual machines touted by VMware/EMC for Windows and Linux servers. The software permits users to carve up a server into multiple partitions and to set up processing, memory and bandwidth limits for each partition."
I have both AIX and HP-UX boxes in my lab, yet have not had the chance to really try these logical partition functions. It is on my to-do list.
