As far as I am aware you get one MRA expressway cluster per UCM cluster. I’m looking at the SRND and you are ok with the backend servers, albeit you are going to need some big servers… to enable all the students, but expressway doesn’t appear to scale to your scenario. Albeit I’m frankly going to guess in a real world scenario you aren’t going to hit close to that 25k number you are positing.</span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D" data-mce-style="font-size: 11.0pt; font-family: 'Calibri',sans-serif; color: #1f497d;"> </span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D" data-mce-style="font-size: 11.0pt; font-family: 'Calibri',sans-serif; color: #1f497d;">I suggest taking to your account team and looping in the expressway BU folks for further guidance as you are definitely on the upper ends of capacity regardless and have an interesting scenario.</span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D" data-mce-style="font-size: 11.0pt; font-family: 'Calibri',sans-serif; color: #1f497d;"> </span></p><div><p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto" data-mce-style="mso-margin-top-alt: auto; mso-margin-bottom-alt: auto;"><span style="font-size:10.0pt;font-family:"Calibri",sans-serif;color:#1F497D" data-mce-style="font-size: 10.0pt; font-family: 'Calibri',sans-serif; color: #1f497d;">Matthew G.

Some of them will want to continue to use it actively, but others might just have it running in the background. Not sure if there are timers that log people out, but it was my understanding that Jabber has been modified to keep them logged in always. This means, those 25,000 active users on campus, now become 25,000 active users off campus.</span></p></div><div><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Verdana",sans-serif;color:black" data-mce-style="font-size: 10.0pt; font-family: 'Verdana',sans-serif; color: black;"> </span></p></div><div><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Verdana",sans-serif;color:black" data-mce-style="font-size: 10.0pt; font-family: 'Verdana',sans-serif; color: black;">Then again, I could totally be missing something here.
