I am asking a question that I am not sure how to ask, so please bare
with me. I am running Sun Ray Server 3.0 on a primary and secondary
server. If I am logged into the primary server and it dies, is there a
way to switch over to secondary without the user noticing any change???
Not with the current setup, that would require mirrored memory between
the machines. Users will get logged out, but they will be able to log
in very quiclly (5 seconds or so worst case)
I've heard some talk about a desire to have a migratable session, where
the user's session can be copied, not in real time, to another sunray
server, so an administrator can take the machine down without any
session loss (users would be disconnected for a few minutes however.)
IF someone would use something like Myrinet, Infiniband, or Quadrics
interconnect between the servers, there is a chance that they could be
mirrored, but that would require a great deal of hacking, probably both
with SunRay Server, and Solaris itself.
NCSM is Non Smart Card Mobility, which basically means the mobile
sessions you can do with a smart card, you can now do with just a
username and password. You have to be running on Solaris for this one..
well, for 3.0 you have to, I'm not sure about 3.1-alpha.
