Basic Design Question

We are lucky enough to be getting a pair of Cisco 9513's for our SAN fabric.
I'm planning out our design and wanted to ensure my thought process is correct.

2-Cisco 9513 Directors each with two 48-port blades (Slots 1&2) and a 24-port blade (Slot 3)
2-Cisco 9124 Switches in an HP c-Class blade chassis
1-DMX-3 with 16 front-end ports
1-CX600 with 4 front-end ports

I was planning on creating a dual core-edge fabric design.

Fabric A:
1 Cisco 9513 and 1Cisco 9124 connected via 2 4GB port channels
(Slot-Port 1-1 & 3-1 with 4GB dedicated bandwidth for each)

The DMX-3 connections and CX-600 connections are going to be distributed among each slot and port groupings each with dedicated bandwidth (2GB).
(I.e. 1-13, 1-25, 1-37, 2-13, 2-25, 2-37, 3-7, 3-13 & 3-19)

All other ports will share bandwidth in an oversubscribed manner.
All DMX ports from FA 8 will go to fabric A
Clariion ports SPA0 & SPB0 will go to fabric A

Fabric B:
Will mimic Fabric A
All DMX ports from FA 9 will go to fabric B
Clariion ports SPA1 & SPB1 will go to fabric B

Any potential problems or items to watch out for?

Thanks!
