About the discussion regarding France Telecom : Their 30,000 UniVerse licences is their installed park : These licences are geographically dispatched onto 5 pairs of IBM servers connected via UV/Net. Each system have its backup system. Daily average number of "Telnet" connected users is 2,500 on server "A", and 1,500 on server "B" Daily average number of "UV/Net" connected users on server "A" is 500 (coming from "B"), and 800 on server "B" (coming from "A") Due to the nature of the applications, "UV/Net" communication between sites are not very frequent but may exist. The large difference between the number of licences France Telecom purchases and their actual average number of users is due to the criticity and "non-stop" purpose of their applications. Due to these criteria, the hardwares are dimensionned to securely support 30% more of system load increase, and so must do the UniVerse and UV/Net licences. I cannot communicate the exact configurations used. In few words, I can say that the UniVerse applications at France Telecom are both CRM and complex technical data management running on servers "A", and proprietary enterprise resource planning running on servers "B". The oldest applications were initially wrote 20 years ago for few tens of users (on "IN2" boxes = "InterTechnique" french legacy hardwares)... and I agree saying that these had to be reviewed in some cases. At present, not all the files on a given server are accessed concurrently by the quoted number of users, but the main files are.

Sent by: u2-users-bounces@ oliver.com 26/04/2004 16:27 Please respond to U2 Users Discussion List What does the hardware look like for a system with this many users ? Are they all running the same apps going after the same data ? Is UV/NET involved ? I curious on how you would scale up to a large number of users running the same application. Would you beef up the machine or would it be better to hook up a number of machines with UV/NET linking them together ?
