I am part of a team designing the infrastructure for a 1:1 Laptop Program. We will have roughly 1,000 users, four different buildings, and mobile home directories. In addition, we will have several graphic labs (G5’s), lit labs (eMacs), and libraries (iMacs). Lastly, we will also have several labs of windoze machines for business apps.
Originally, we were looking to one Dual G5 X-server loaded with memory to serve as an Open Directory Master to manage desktops, laptops, and host the users’ home folders. Recently, we were advised to explore adding replica servers to lessen the load on the single box.
Are we expecting too much out of a single machine?
How many additional replicas should we add for 1,000 users?
Is there a guideline – for example – 100 users per replica?
Any help would be appreciated. Thanks!
