Build a Network

I need a network design for the following. Site1: Modern Office#1 block (HQ) of 7 floors with Sales, Finance, IT, and Call Centre departments. Each floor has a maximum capacity of 100 desks with standard PC installs (350 users planned initially). Core network is located in theComms/Serverroomonthe1st floorwithamixof150xphysicalandvirtualservers. Site2: Warehouse in a separate location, about 1km away from Office#1 block. Used for “credit/debit card” manufacturing. PCs for inventory and tracking are used. (35 users planned) Site3-7: Remote Branch offices (5x) providing small localised services. (20 users planned per site) Site8: Disaster Recovery (DR) site located in a secure Colocation/Data Centre in a different country. This is used to backup the core network facilities in Office#1. Layout and services are replicated. There is a mix of 80x physical and virtual servers. Note: Of the 500 employees, 200 need 24x7 VPN/RAS access and sites 3 to 7 are used for hot desking (mobile users) External connectivity for 3rd parties/partners is via the Internet and must be firewalled WAN technology used should be appropriate for the site and interconnectivity with other remote sites DR site is privately interconnected to Office#1 Voice over IP (VoIP) and Multimedia technology is optional All LAN cabling distances between PCs/Servers and networking devices should be less than 100m LAN technology is Ethernet based IPv4 only is assumed VLANs/IP Subnets need to be allocated for all networks and sized appropriately depending on their function
