Re: Hard disk compatibility (ST32000444SS)

Thanks - and weird... The part number is correct  "EMC PN: 118032750"

Edit - actually there are 2 part numbers - one on the disk itself and one on the drive caddy - the correct one is 005049277...

I've heard now from the seller those drives came from a cx-4pdae-fd...

Is that an older or newer modell? And is that one i might use stand alone? - Yet again the search yields no results, sorry

Edit2 - I've found the disk in https://community.emc.com/servlet/JiveServlet/download/613517-37338/All_CLARiiON_Disk_and_FLARE_OE_M..., listed for VNX platforms... weird it was used in that cx machine then?

Thanks,

Thomas

like you mentioned earlier, you will need a controller (service process) to take advantate of these drives. This is what CX4 looks like

Ah ok, i see...

well too bad, because a cx-4pdae-fd or KTN-STL4 which seems to be another name is fairly cheap to come by... Adding an storage processor will negate that cheap array factor.

Thanks - and one final question - if i change the block size and use it in a regular pc/server will i ever be able to use those drives in an EMC again (by reformatting with 512b block size o/c)?

i am not sure, they get formatted at the factory. Here is a note from one of the documents:

A drive sector typically contains 512 bytes of data. Many VNX configurations and tuning options are in block-size units, which is 512 bytes. VNX drive sectors contain a total of 512 bytes of data and 8 additional bytes of metadata, totaling 520 bytes.

I am afraid if you format them for PC/Server use, you will not be able to use them in Clariion/VNX again, the firmware (FLARE) will not recognize them.

Found it, it can be used in any VNX model. It's a 2TB 7k2 RPM 6Gb SAS drive, including the VNXe models. The VNX is the "new" CX. In fact it is newer than a CX. They don't make CX's anymore.
