Shalom Vanadio,

Exact specfications for all workstations are at http://docs.hp.com

If you'd posted the machine type I could have been more specific.

Re: PCI slot types reference and specifications

Hi Steven I'm looking for a link to something that explain the _general_ specifications of these kind of buses. No relation to which server / workstation they are in.

Something like: PCI X slot is long x cm... cards have n tabs, bandwith is ... etc.

Thank you.

Something like this?

Still looking for a document for PARISC/Itanium HP-UX Capable servers.. there used to be one. Perhaps it is described along with the server docus -- along with how many PCI, PCI-X capable slots each has.

Re: PCI slot types reference and specifications

From the HP doc posted above:
"You can use a 32-bit card in a 64-bit slot and vice versa"

Good news!

So the 64/32 auto switching affects only the bandwith at wich the card will operate?

Thank you!

Re: PCI slot types reference and specifications

Yes.

The newer PCI-e (PCI Express as opposed to PCI-X) offers what's called rails.. to denote max speed: x1, x4, x8 and x16 -- I do not know if eventualy PCI-e slots will in the future be adopted on the enterprise servers...
