Hello Guys

I got my very first DELL Switches and want to setup a complete brand new netowork. below is list of devices I got.

2 * Dell Power Connect 6224 (24 Port Switches)
2 * Dell Power Connect 2848 (48 Port Switches)
1 * Watchguard XTM 505 as Internet Firewall

MD 3200i with 4 Ports on Each controller totaly 8 Ports.
2 * Dell Power Edge R720 Each with 8 Ports.

6 other servers ,

Both 6224 switches are stacked by using stacking modules . i think this should be as standby stack for failover ISCSI cluster.

MY Plan is to use 6224 switches to connect 2 R720s , MD3200i to create a failover hyper cluster, plus i will connect 2 more servers by teaming there network ports so one cable can go to each 6224 switch. all servers will connect to 6224.

Watchguard Firewall LAN bridged ports will connect to both 6224.

then switch on 1st Floor 2848  needs to conenct to both 6224 switches if am correct . on 1st floor switch i want to connect about 40 computers and printers in one subnet 172.16.13.X  and another subnet for Wi Fi Access Points 172.16.14.X

and another 2848 switch on 4th Floor needs to connect to both 6224 same as other and i need same subnets on that 172.16.13.X for desktops  and 172.16.14.X for Wi Fi Access Points.

Virtual Server Network from hyper V hosts + another physical servers needs to be in diffrent subnet (172.16.12.X)

according to above complete network setup i will need few VLANs, allow traffic between them and allow traffic out to watchguard firewall for internet access.

also I will have Active Directory , Exchange Servers in server list and PCs on diffrent subnet needs to join AD domain and access all services. DNS, DHCP from server subnet.

can someone guide me the best way to implement this. where VLANs needs creating on both 6224s or 2848s. i attached a diagram of my plan.  plz mind the drawing its not best but hope you can get some ideas out of it for what am trying to achieve.

Many Thanks.

in Diagram

S1 = PC 6224
S2 = PC 6224
S3 = PC 2848
S4 = PC 2848

on top is Watchguard Firewall its 2 LAN ports needs to goto both 6224
