i guess not!

not sure if this is of importence but DAE and DAE2 uses green LEDs and stilletto uses blue...

Oh I need some stiletto to light my bedroom !!

-s-

black light and disko ball ?

Expensive version of a bedroom disco indeed.
I can sell you stuff like this. How may we contact you ?

Maggie,
Apart from the coolness of blue LEDs (have you noticed that all the really cool products use blue LEDs? My radar detector with the blue LEDs was 50$ more than the one with red LEDs) you can read about the differences here:

Support > Technical Documentation and Advisories > Hardware/Platforms Documentation > CLARiiON CX3 UltraScale Series Systems > CLARiiON CX3-80 > General Reference > DAE2P and DAE3P Disk-Array Enclosures Hardware Reference -- A04

... and here:

Support > Technical Documentation and Advisories > Hardware/Platforms Documentation > CLARiiON CX Series Systems > CLARiiON CX700 > General Reference > 2-Gigabit Disk-Array Enclosure (DAE2) FC and ATA Models Hardware Reference -- A07

Briefly;

DAE - the generic term for an enclosure, and does not refer to a specific enclosure used on CX-series or CX3-series

DAE2 - the 2Gbit/sec enclosures originally introduced with CX200/400/600 and also used on CX300/500/700 (until DAE2P was introduced). These enclosures support Fibre Channel disk drives at 2Gbit/sec interface speed. These enclosures do not support ATA drives. These enclosures are forward-compatible with CX3-series.

DAE2P - the 2Gbit/sec enclosures introduced with CX300/500/700 to replace usage of DAE2 there. These enclosures support Fibre Channel disk drives at 2Gbit/sec interface speed, with point-to-point connectivity. These enclosures do not support ATA drives, and these enclosures are not supported on CX200/400/600 arrays. These enclosures are forward-compatible with CX3-series.

DAE3P (aka DAE4P) - the 4Gbit/sec enclosures introduced with CX3-series. These enclosures support Fibre Channel disk drives or "CX-SA" model ATA disk drives at 4Gbit/sec interface speed, with point-to-point connectivity. Note that the mixing of Fibre Channel disk drives and ATA disk drives within a single enclosure is not supported. These enclosures will also support 2Gbit/sec operation (FC drives from DAE2 or DAE2P can be used in these enclosures). These enclosures are _not_ backward-compatible with CX-series. The different color LEDs are indicating if the enclosure is operating at 4Gbit/sec or 2Gbit/sec speed.

There is also one additional enclosure type;

DAE-ATA (aka DAE2-ATA) - the 2Gbit/sec enclosures used with CX200/400/600 and CX300/500/700 for "CX-AT" model ATA disk drives at 2Gbit/sec interface speed. These enclosures do not support Fibre Channel drives. These enclosures are forward-compatible with CX3-series.

which enclosures allow mixing fibre and ATA drives?

That has been discussed at length already;

The mixing of FC and ATA drives is not supported within any enclosure.

Don't focus on the connector - think of it this way;

Given a DAE2 or DAE2P enclosure, the only drives that can be put into it are Fibre Channel

Given a DAE-ATA enclosure, the only drives that can be put into it are ATA (CX-AT type)

Given a DAE3P enclosure, you have a choice of what drives to put into it; Fibre Channel or ATA (CX-SA) type ***but not both***

DGM

thanks, its clear now..

yes, i was confused by the same thread
does the common drive-canister connector apply for just CX-3? or does it mean that it applies to CX as well but since the FLARE puts restriction on drive mixing, we can mix the drives in an enclosure logically but not physically?
