Datacenter Block is used to host the Shared applications
access by the entire UAEU. Existing cisco Nexus 9508
switches are deployed in the Datacenter Core layer and
new Cisco nexus 9396 are being used to aggregate the
Servers acting as top of the rack switches. Datacenter
to campus core connectivity is fully redundant 40Gbps.
Inside the datacenter, the servers connect to the switches
using both 1gbps links on the physical servers as well
as multiple non-blocking 10Gbps links using fully
virtualized Dell blade chassis. Moving ahead, the server
team plans to virtualize the complete DC environment
with at least 10G uplinks.
Campus Core block will be used to route traffic between
multiple blocks i.e. traffic across multiple block has
to transit through the Core network. Two Cisco Nexus
7710 switches will be used as Core switches, which will
have dual 40Gig connectivity to DC Core Switches and
multiple distribution blocks.
Services block
comprises of internet gateway routers
and perimeter firewall, which terminates the internet
service provider connections. The perimeter firewall now
connects to the campus core using multiple 10Gbps, non-
blocking, fully redundant connections. UAEU connectivity
to the internet is also completely redundant as the
gateway router are both dual-homed and multi-homed.
