The J4400 (and J4200) are not Sun's own hardware products.  They are 
manufactured by Quanta as the 1400 and 1200 SAS JBODs.  Sun do their own 
firmware to make it a Sun product.  You will be able to get both the drive 
brackets and SATA interposer cards through Quanta distribution.

The other way to get the bracket and SATA interposer card is to buy the 
cheapest Sun SATA drives - see if you can find someone with stock of the old 
250GB or 500GB SATA HDDs, remove that HDD and fit your new 2GB SATA HDD.  We 
bought a lot of the Sun 250GB SATA HDDs for this very purpose, they cost us 
about US $140 each.

Also, the J4200/J4400 air management sleds (MN: XTA-4400-6AMS) are a fully 
functional drive bracket with a screwed in metal tray that substitutes for the 
actual HDD.  It doesn't have the SATA interposer card, but if use use SAS HDDs 
rather than SATA HDDs you are now home free.

You can use the Seagate 1TB ST31000640SS SAS drive with a drive bracket, or you 
can use the Seagate 1TB ST31000340NS with a SATA interposer card.  The drive 
brackets have two sets of drive mount holes to deal with the differing position 
of the HDD depending on whether it needs the SATA interposer card, or the SAS 
HDD directly plugging into the backplane.  We have used both of these as 
methods of adding HDDs to J4400 systems, and we have these in constant use 
without issue (Sun CAM complains but that's OK).

So for 2GB HDDs, you would use the Seagate ST32000644SS for SAS though it's a 
6Gbps SAS HDD but it will have to run at 3Gbps in the J4x00 JBOD - so check 
this before buying any quantity. The Seagate ST32000644NS is the 3Gbps 2GB SATA 
unit that should work with the SATA interposer. Once again, check before 
committing to any quantity. Or send us either or both and we'll run it up and 
check it for you!

Our preference is to use the SAS drives rather than the SATA drives with the 
SATA interposer. It's simpler, true dual-path, provides clean MPX-IO, and the 
SAS HDD may be less that $100 more expensive than the SATA HDD.
