Please suggest - To whom should I link my Miniport (SCSI port/Storport or ATA port)

NTDEV
1

Folks,

I am new to storage stack and Storage port drivers. Still deciding which way
to go.
I have my lower edge as ATA (and or SATA).

From what I have looked from WDK docs, it looks that it can be done by
writing a SCSI Miniport.
WDK docs also says that vista onwards one can use ATAport driver instead of
SCSI Miniport for with ATA lower edge (it doesn’t mention anything about
SATA).

However systems supported would be XP onwards. So for below VISTA systems
implementing a SCSI Miniport is the best approach?

Please suggest (and correct me also if I understood/saying some thing
wrong).

Regards
Deepak

Yes.

And, if you don’t want to maintain 2 drivers, then use SCSIPORT’s miniport for all OSes.

scsiport is generally the approach taken. It is on its way out however.

If I am not mistaken, one of the later XP service packs provides STORPORT.
That provides a little more flexibility that SCSIPORT, but will depend on
how old an OS you need to support.

Never saw it in XP SP3, more so, Hyper-V’s guest SCSI driver (storvsc) cannot load there due to lack of STORPORT.

I believe it started in Windows 2003 not XP.

You may be right. It was the Server 2003 DDK where I first saw it.

That provides a little more flexibility that SCSIPORT, but will depend
on how
old an OS you need to support.

I think you are mistaken, for 32 bit at least. It could be that the 64
bit versions of XP support storport as they are derived from 2003…
maybe that’s what you are thinking of?

I can’t say James. It was sometime around the release of the Server 2003
DDK, so it’s quite possible what I saw in that jpackage I ASSUMED was for
all platforms.

I believe storport WAS in the XP SP1 64-bit OS.

What I’m wondering is did the XP SP2 OS kernel support the features marked
as Win2003 kernel only, as I seem to remember Win 2003 SP1 adding AMD64
support, and XP SP2 happening at the same time to support XP 64-bit.

I’m specifically wondering if large page support to VirtualAlloc (and kernel
memory manager calls) is available in XP SP3 (which is also supposed to be
the same as Windows 2009 Embedded?

A little more detail in the API docs on when a feature arrived would be
nice.
