I am planing to redesign our current DC network and expected to have Network Failover (HA)(Active/Standby). So i budgeted to buy 2 x ASA5510 and 2  x GE Switches. Attached is my Plan in mind. can some body verify, whether need to amend anything in my approach?
1. Firewall to Firewall connection required
2. What action required to take if Primary Firewall or switch fails.
3. Witch is the right approach of keeping Servers in each VLAN (WEB, APPlications & DB)

Network design and methodology, also known as network architecture, is the design of a communication network. It is a framework for the specification of a network's physical components and their functional organization and configuration, its operational principles and procedures, as well as data formats used in its operation. In telecommunication, the specification of a network architecture may also include a detailed description of products and services delivered via a communications network, as well as detailed rate and billing structures under which services are compensated.

Network Architecture

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.
