I'm putting together a proposal for a greenfield 10GigE network (including 10GigE uplinks to providers) while trying to be careful about budget.
One of the hardware configurations I'm evaluating that would be relatively inexpensive is a blade chassis with a 10GigE uplink module that gives me a set of 2 CX4 connectors + 1 SFP+ connector (there's no good way to substitute a fiber module in this configuration without exploding the budget).
While the SFP+ would be fine IF the datacenter supports SFP+ (which is still pretty new), CX4 obviously isn't going to work for uplinks to providers, and we'll need more than one 10GigE uplink.
HP offers CX4->Multi-Mode Fiber adapters for their ProCurve gear for less than $1000/each. This would be fine, but the problem is the CX4 adapters aren't coming out of HP/ProCurve gear. I can't seem to find non-ProCurve adapters.
So there are several inter-related questions here:
- Do the ProCurve adapters work with any CX4 connector?
- If not, are there "generic" adapters out there that do?
- Are there likewise any SFP+ -> MMF adapters available in case the provider doesn't support SFP+ yet?
Edit: Couple extra details:
- The blade system is from SuperMicro, and their network modules are visible here: http://www.supermicro.com/servers/blade/networking/
- I'm trying to avoid having to buy an external 10GigE switch to uplink the blades to.
- We will eventually probably have to go 10GigE top to bottom (sticking Infiniband modules in the blades for use as 10GigE adapters) and switch to SuperMicro's 10GigE pass-through module with external 10GigE switches, but I want to put that off until the project is showing a return on investment.
Edit II: chris's answer set me straight on SFP+ (for unknown reasons, I'd confused it with 10GBASE-T in my mind). I'm still hoping for a pointer at CX4->MMF converters, however, since one or two 10GigE uplinks through SFP+ won't be enough long-term -- I'm looking to eventually push close to 30gbps out per chassis.
