I read somewhere that using another serdes-IC would do the trick
with the V2Pro? Or are you saying that creating a fully
SATA-compatible datalogger just isn't doable? Another thing is the
ability to connect a SATA-device to the Virtex-II Pro for
use with linux running on the embedded PowerPC-core.

xilinx rocketio is not fully SATA compliant so the SATA sockets on
ML300 and XUPV2P are just someones
"wishfull thinking.." !
on the ML300 I did someting useful with the SATA connector, namly I did
take a SATA cable cut it half, soldered a buzzer onto it, then plugged
into SATA connector on ML300 and programmed the rocketIO on the ML300
to make an audiable
BEEP BEEEEP BEEP
pretty expesive way of making BEEP (4600 USD !!)
you can do the same on your board, for less money :)
ok, jokes beside I have implemented a SATA OOB circuitry with NO
external circuitry with V2Pro rocketio

but--- for you best advice
just forget those SATA sockets!!! (unless you want to make a BEEP)

Do you recommend the Digilent board? I want to practice my skills on
high speed comms using this board and also want a flexibility to work
on some algorithms like MPEG etc..
Cheers

the V2VP30 board for the uni price?
sure !!
that price is below component self cost !!!
just done excpect find nice and easy workin SATA solution for that
board (or in that matter any V2P board)

The SATA connectors are useful for Board-to-Board communication using
the Aurora protocol.
The "Using High Speed Serial MGTs with the Aurora IP" Quickstart at
http://www.xilinx.com/univ/xupv2p.html is a good place to start.

sure they can be used for any non-SATA protocol you can imagine, be it
Aurora or something else.
but having SATA connectors on board is very misleading as people will
think the SATA connectos could be used for SATA !!!

I've contacted TaraCom now, at least.

almost everything is doable. the question is what is reasonable.
you could be lucky and get v2pro serdes working with SATA too with some
limitations and with huge amount of work.
as of using external SATA PHY well that would work, but the problem is
that SATA PHY is pretty much not available at all, you are welcome to
try find one, but I am 99.99% sure you will not get any. OK, that was
situation a year ago, maybe its little easier today.
sure using v2pro serders and ppc-linux would realy COOL, too bad it
doesnt work out that way :(

they only list various PCI to SATA chips or SATA to PATA-(device)
.... All those chips that could be used in the mass-market
for desktop PCs :-(
looks like there is no way other than using PCI-whatever?
SI once had a SATA phy on their homepage but it was far
from beeing available ... their local representation
did not even know about it ...
BTW: some time ago there was an announcement from TI to build
a DSP with some Rapid-IO interface (C6455) ... It would be
really cool to connect *that* to PCI-e and SATA directly ...
I asked them - they did not even think about that opportunity :-(
bye,
Michael |

marvell has PATA<->SATA bridge that is available for low volume
ordering - it easier to connect than PCI-SATA

Ok, here's the thing. They have limited amount of samples, so they won't
sell/give those to anyone but high volume cases. I've asked about
when/if they expect to get new batch of chips/samples, and if it's possible
to buy from them when/if they do.

exactly as expected.
unless you are 10M pcs/year customer you dont get SATA PHY's
