Recommended server specs for NS 7.1 for a 10k client organisation
We're struggling at the moment with a really poorly performing NS installation at my organisation. At present we have around 2500 clients with the agent installed, and the NS server is struggling to say the least. Against advice, our server team provisioned this server on a VMWare virtual server. It has 4 virtual CPU cores, and it initially stated out with 16GB of shared memory allocated to it. I'm fairly confident this was underspecced for the number of clients we were going to place onto the system. We've since coaxed them into increasing the shared memory to 32GB, however this hasn't made a great deal of difference to the performance of the solution.
Now as a result of what I think is an underspecced sever, the console runs like a dog, making it painful to use. We now also need to roll out the agent globally to all of our other sites, bringing the client count to around the 10,000 mark.
My question is... I realise our current NS server will not cope with 10,000 clients (it barely handles 2,500), and we'll likely want to move to a physical box with dedicated memory. What sort of specification of server would you recommend for an estate of 10,000 clients?
In addition to the NS server, each of our sites has a site server installed, including the headquarters where the NS box is located. These site servers run PXE services as well as package and task services. One issue we have is at our HQ, it seems that half of the 1,500 clients on this site pick up the NS as their task server, and the other half pick up the site server. How do I force my clients to utilise the site server only? I'm assuming this will reduce traffic and load on the NS?
Last question, for a site server running PXE, Package and Task on a site with 1,500 clients, what spec of machine would you recommend?
Thanks for reading and I look forward to your responses.
