It all depended on the mode

If the enclosures is a DAE3/ DAE3P then they are backward compatbile

There is no 8gb enclosure for CX4

this will give you a better picture.

DAE2P and DAE3P (2/4 Gbps)  enclosures are supported with CX4 systems also.

what we have on CX4 is you can have 4/8Gb frontend fibre connectivity ports,

Even on VNX we use a 6Gb backend on the DAE (24gb shared across the entire bus)

Thanks Gearoid.

Hmm, looks like I have been missinformed on it's origin, However I was told it's 8Gb?, Which SAN model supports 8?

Cheers Vipin V.K thats a good doc!
