CLT will be hosting their infrastructure on Microsoft Hyper-v virtualization stack. The virtual infrastructure servers will host Microsoft Exchange Server, Microsoft Active Directory, Microsoft System Center Orchestrator, File Server, CLT Application Servers, and Microsoft SQL Servers etc.
CLT has 3 Production VLANs and 1 Client VLAN configured on Cisco hardware, each VLAN is configured on Cisco switches 3750 series, a dedicated patch panel separates Management switches and Clients / Servers. A Fabric interconnect provides management interface which is layered between Layer 3 switch and Cisco UCS Blade servers.
Each of the VLAN has mix of Unix and Microsoft Servers. Most Microsoft servers are virtualized and staged on Microsoft Hyper-v with appropriate VLAN tags configured for communication between servers and Storage arrays.
CLT is engaging SKV, a Microsoft Premier Consulting firm to perform DNS Designing and Configuration which involves configuring DNS servers in three Active Directory Domains and establish communication across the DNS servers.
