If it's under 5m I'd recommend a twinax (DAC) cable.  cheaper and much easier to deal with. I have a customer with a 4020, I can check when I'm onsite in a few day for the transcievers, typically the ones that work with the switch work with the storage device.

It;s a 4020i, not 4020. 10Gb DAC would be ideal but not sure if Compellent are fussy about the ROM in the cable ends.

I used some Cisco twinax to an sg8f8t with no issues, they have never been picky for me.

I think you guys are right, the spec sheet says they are "SFP+ only no 10GBaseT" so maybe restricted to DAC cables rather than separate transceivers.
Paul SolovyovskySenior IT AdvisorCommented:
Using several Dell DAC cables on the same unit, no issues at all.  If it's SFP+ you can either use a single DAC cable at a low cost and it includes 2 SFPs (one on each end) and cable or purchase 2 SFP+ transceivers and a multimode optical LC to LC cable.  The DAC cable is 80% lower cost so if you are under 5m  it makes the most sense and is more durable.

What switch are you connect to? I have used these for Dell N series switches

1.      Dell DAC-SFP-10GB-5M  
2.      Dell DAC-SFP-10GB-2M  
3.      Dell DAC-SFP-10GB-1M

My switch is 1Gb Ethernet.
Paul SolovyovskySenior IT AdvisorCommented:
SFP+ is 10Gb  while SFP is 1Gb.  What model switch are you connecting to?  I'm not sure if you'll be able to step down from 10GB to 1GB on the storage side, it's worth a call to Dell to verify.

Good reference with respect to SFP and SFP+, you need to ensure that your switch and storage support the same standard.
