I hope I can get some inputs from you on network design.
This electronics manufacturing company will be building a 2 storey, 100K square foot facility.
The mail floor - all the manufacturing machines, computers and servers running manufacturing software
The 2nd floor - the main server (Microsoft SBS), SharePoint Server, LOB software servers, and computers used by office staff and engineers.
They have less than 200 employees, over 120 computers, 5 physical servers, some VoIP phones. They are all on the same network. Currently, there are only 28 IP free addresses available from the DHCP server (Microsoft SBS)
Here are my thoughts about the network in the new building
1. Install stackable switches in each floor's server room. Connect the two groups of switches via a long high speed trunk cable running thru the floor.
I think this will keep the network traffic on the main floor in the main floor network from the 2nd floor network, which optimize the bandwidth.
Currently, they are using D-Link DGS-1510-52 switches, which have been quite reliable, except that i had to power cycle one of them twice in the past years, and their firmware are a bit buggy.
Is it worth to deploy Cisco switches which are more expensive and cause a learning curve? Is there such a long high speed trunk cable at all?
2. Separate computer network, VoIP phone network and Security/Access Control network with 3 different networks.
This will release quite some IP addresses from the DHCP server, and ease the traffic on the computer network.
Does this make sense? How can I do this? Will this cause any inconvenience/issues if i separate the computer network and VoIP phone network?
3. They need a WiFi system covering the whole building for both internal and external users.
I will be looking into Ubiquiti's stuff. I have been happy with their UniFi wireless AP, but have not setup multiple units to cover such a big area yet. I will consult them for help.
That's not all my questions at all, if i miss something or if i should be aware of something, please do not hesitate to let me know. Any thoughts are greatly appreciated!
