No, this time it's not about how long a particular version of Solaris is on the market. I covered that already (although in German only) ;-) This time it's about how long a server can remain up and alive and deliver its service. But see for yourself:
I saw this at a customer that fears only two things: A call from service, requesting the latest kernel patch, and the upcoming consolidation project. The latter is the more likely event that will stop him from reaching 2500 days with this server.
