Hard Drive Model Number Matrix: Assembly 518194-002

[epretorious]

I've noticed that the 300GB 10K 6GB 2.5" SAS HDD appears in the Hard Drive Model Number Matrix three times in two different sections: Two entries in the hot-plug section and one entry in the non hot-plug section...

Serial Attached SCSI (SAS) SFF 2.5" Hot-Plug Hard Drives for other uses / SFF 2.5" Hot-Plug SAS Drives

Serial Attached SCSI (SAS) 2.5" SFF Non Hot-Plug Hard Drives / Non Hot-Plug SAS Drives Bare Drive

537809-B21 537820-001 300GB 6G 10K rpm, SFF 2.5" Non-hot Plug Dual-Port SAS hard drive

Why is this? Is it just a typographical error or is there something more subtle that I'm missing?

Just based on the above, I'd guess that the second hot-plug is a 3G disk.

But it does seem strange that the 3G and 6G disk would have the same model/spare/option numbers..

Thanks, Johan.

I understand the bare drive model number and the bare drive assembly number but what are the spare and the option numbers?

[Johan Guldmyr]

option - when buying

spare - when getting a replacement or perhaps also when buying

when you get/buy either of these, you may not get exactly the same disk drive model but any that is equivalent

To be precise

* It all depends on the spare part number
* All 3G speeds hard drives have been upgraded to 6G
* As you see first two entries have same spare part number and same b21 number ( this could be a duplicate entry )
*** Finally the last entry has a different spare part number for the same model number as all the specs are the same compared to the first two apart from the third being a Non Hot Plug Hard drive , same hard drive with just a hot plug caddy
