Hard disk compatibility (ST32000444SS)
Hi,
first - I am a completely newbie regarding EMC products so please excuse my lack of knowledge.
Second - I recently acquired a couple of 2TB 7200 RPM SAS drives (ST32000444SS) on a well known marketplace...
The seller unfortunately failed to mention that those drives were from an EMC storage array and included an EMC drive Caddy and probably EMC Bios.
So now I think I have several options:
1. Return the drives - possibly the easiest solution, I've contacted the seller regarding this
2. Sell the drives on - possible too - I've paid around $180 per disc - is that a reasonable price or cheap or a ripoff?
3. Try to remove the caddy and force flash a regular Seagate bios on them to get them recognized by a regular SAS controller - Is that even possible?
4. Try to get hold of an EMC storage unit to use them as they are...
a. Which storage Units support these drives - and which one is the oldest and thus possibly cheapest?
b. Which components do I need to get this running? I suppose the regular list would include Storage Processor, Drive Array, SAN switch and FC HBA? I believe one can leave the SAN switch out - but do I need a storage processor or can I directly attach a drive array to a FC HBA in a server?
Any comments/help or link to documentation regarding this would be greatly appreciated:)
Regards,
Thomas

Well that was one of my initial questions;)
Which is the oldest array which will accept those drives
?
Which limitations do these have? size? disk type?

Anyone knows where to search via this partnumber?
Standard search yields not many results....

that part number does not look like what EMC uses in their documentation, see attachment

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_Matrices.pdf, listed for VNX platforms... weird it was used in that cx machine then?
Thanks,
Thomas

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.

Ok, as expected.
Thanks a lot for your help:)

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.
