Hello,
I have been reviewing the documentation for the Junos upgrade process of the EX4600 and to be honest it gets less clear each time I read it. Specifically, I am looking at the nonstop-upgrade versus the in-service-upgrade process.
Setup: in my situation the EX4600 will sit in a three member virtual chassis as our network core. Two in the main server room, and one in a secondary location for redundancy. Right now, the two in the main server room are RE and BK because they are directly attached via 40GB cable. The third "LC" is connected via 2x10GB fiber to each to complete the loop. Nearly all remote locations are connected via link aggreagation so I can lose one member at a time without issue.
My concern is that we are a small hospital and I need maximum uptime but also need to keep things current. Which of the two upgrade options is best for this setup? Also, if you see a problem with this setup feel free to voice it. I would rather plan for problems now than react to them during an outage.
Thank you,
Todd
