I am working on a requirement on virtualisation involving Business crtical applications in multiple data centers. The challenges being currently faced are:
1. The 3 Tier architecture with web servers, app servers and db servers to be virtualised with common ESX hosts along with multiple other intranet applications. Issues around security between environments, management of ESX, logging etc.
2. multiple swtiched environments to be virtualized with clash of Vlan id's, Vlan in excess on 512 to be trunked.
3. The ultimate goal is to go for the complete virtualised environment with full DR capability and flexibility akin Cloud computing.
4. Can we think of Q in Q support on Nexus 1000v?
Any help in untangling this situation will be highly appreciated.
