ReadyNAS 4200 + 10GBe Option

1) Are these CX-4 ports in addition to the 1GB onboard NICs

Yes. Both RN12G1220 and RN12G0620 support 2xGigabit ports + 2x10GbE ports (CX-4)

2) All of Netgear's switches that support 10GBe only have XFP Fibre modules, I can find CX-4 modules for say the GSM7328FS so how can I connect my ReadyNAS to it at 10GB or do I need to go somewhere else for a switch.

4200 also supports SFP+ 10GbE connection. The Netgear PN for that is RN12S1220 and RN12S0620. Similarly those units have 2xGigabit ports + 2x10GbE ports(SFP+ , fiber or copper).

NETGEAR ProSafe GSM7328S-200 (or GSM7352S-200) support the CX-4 10GbE ports. 2 switches needed for a stacking configuration with AX742 24Gbps Stacking Kit.

3) The ReadyNAS 4200 seems to only come with the 10GB modules or "with a 10GBe option" does this mean I can add CX-4 ports later on if I decide to buy a 4200 without the 10GBe adapter.

4200 comes with 3 group of configurations:
1) with standard gigabit ports but can add the 10GbE package later (CX-4 or SFP+)
RN12T1210
RN12T1220
add-on cards -
RN12T2SFP (2x 10GbE ports SFP+)
RN12T2CX4 (2x 10GbE ports SFP+)
2) with 2 gigabit ports + 2 10GbE ports (CX-4) built-in
RN12G1220
RN12G0620
3) with 2 gigabit ports + 2 10GbE ports (SFP+) built-in
RN12S1220
RN12S0620

Hope this helps.

I love the diagram but let me add one more variable to that particular design:

What if you want to have 2 ReadyNAS 4200's in this and still have the Server with 2 x 10GBe SFP+ ports? In other words, I would want 4 - CX4's, 2 SFP+'s and 2 slots used for the stacking kit. My goal is to have a little bit of redundancy. Can you setup the ports in an active/standby role where the active can be a 10GBe and the standby could be a 1Gbe that would become active if the 10GBe loses link? Right now my resellers don't seem to have the S version available for ordering, only the G and T models. Ordering that model would solve the problem.

What are the chances that Cisco twin-ax SFP+ cable (E.G., SFP-H10GB-CU3M) will work when plugged into a 4200 with SFP+ ports?
...or, differently...
What would Netgear reccomend/support as a method to connect a 4200 to a Cisco 4900M switch?

Chances are high that it will work. The supported deployment would be to use a Netgear connector along the lines of the AXC763.

Ah, that gets interesting, thank you. Is there any certification of interoperability with that cable/transceiver and Cisco kit (specifically a OneX Converter Module from the Netgear side? Or whom should I contact about that because I understand it's not really a ReadyNAS specific issue. (For some of the Cisco Nexus devices, Cisco documents that some twinax cables from NetApp, EMC, &c. work, but not any from Netgear.)

Is there anyway to get a statement about compatibility of the CX4 interface with non-Netgear CX4 cables and non-Netgear CX4 switch ports at the other end? It has to plug into a Cisco X2 port, which looks for a Cisco cable.
