I would like revisit a previous thread here: http://www.gossamer-threads.com/lists/nsp/juniper/58555
With the new RE-S-X6-64G routing engine, is part of the goal here to provide a method to eliminate the need for a redundant routing engine in the MX?
Right now, we do employ redundant routing engines (1300s and 1800s), but mostly with ISSU in mind. The failure rate for routing engines, even with the older hard disk models, has been rather low, in our experience. So, the primary benefit has been to provide support for "hitless" upgrades via ISSU.
Unfortunately, our experience with ISSU has been disappointingly mixed, at best. Granted, even with our problems with ISSU, our outages due to ISSU failures are much shorter, as compared to trying to upgrade a router with a single RE.
But if the prospect of using VM technology on the RE-S-X6-64G includes the possiblilty to do ISSU with only a single RE, that would greatly reduce our requirement to supply dual REs in our MXs.
It would be pretty sweet to free up that redundant RE slot for something revenue producing.
Is this a legitimate expectation that I have; i.e. a single RE-S-X6-64G doing hitless ISSU, or am I just dreaming too much? Are there restrictions on the RE-S-X6-64G regarding this functionality, and if it is not here yet, is there any release train where it is expected to come?
