HP has gone really, really public about its support for Sun’s Solaris 10 operating system by sending out an internal memo. HP has long ‘officially’ supported various versions of Solaris on its Xeon- and Opteron-based servers. Now, however, it’s kind of ready to talk about this support. The company this week ‘announced’ support of Sun’s version of Unix in a statement to staff, according to insiders. The Solaris embrace is being pitched as HP’s answer to disgruntled Sun customers trying to make their way off SPARC systems and onto HP’s x86 kit.
