Hi chetan,

As desiging we used to deisgn Data center in 3 tier mode like we server in one zone with one dedicated firewall for ineternet traffic and application server in one zone with another set of firewall gaurding the traffic and database servers for another zone with same firewal gauaruing the traffic.With having secuirty devices in between like IPS and Load balacners on differnect segment to load the tarffic coming in servers with full redudancy you need to have every thing in dual mode like Lan switches,NIC in server,Load balancer,IPS and Firewall to have zero percent loss in Data Center.
