Connecting 300 IP Cameras using Cisco Switches

Question

Require help on a Case study. (Can only use Cisco switch)
Description:
This is a setup required for 300 security cameras.
So availability and redundancy is important.
I have calculate the bandwidth using [URL="http://www.jvsg.com/download/IPDesignToolSetup.zip"]this software[/URL].
If each camera is set to 5MP and H.264-10, Bandwidth is 12.08Mbit
So 300 cameras will require at least 3624.96Mbits in total.
(correct me if i am wrong)
Each NVR has 32 port.
It will be just connecting within a LAN.
Here is the brief 2 possible design I have draft out, but I am not sure which model and series of cisco switch to be use??
Design 1:
Design 2:
Please advise which model and series can be used for this 2 two of design.

Answer 1

Hello Chun,
you need to accomodate 300 cameras and 32 ports for each network video recorder.
data flows are from cameras to network video recorder ports.
The amount of traffic per port at port connected to cameras is not huge and total traffic from cameras exceed GE links
48 * 12,08 =       ?? in any case less then     < 1 Gbps
You can deploy a hierarchical network design with an access layer made of switches with fixed configuration 48 ports and GE uplinks like a C3750 with 48 ports or  a 2960 with 48 ports (if it exists)
Each access layer switch needs to have two uplinks to distribution switches
And you need 300/48 switches => 7 switches     => 7 GE uplinks on each distribution switches
Distribution switches should be two and should be able to connect to access layer switches and to NVR that requires 32 ports each.
Different solutions are possible:
instead od deploying 7 standalone switches with 48 ports each you could use two modular C4507 equipped with  WS-4548 48 10/100/1000 linecards
the distribution switches can be two C3750 E, eventually configured and connected as a stack, to allow to use both uplinks of each access layer switch
Hope to help
