HP DL360 G3 - PCI-X Slot

[grantwatson]

Hi All,

I'm using a HP DL360 G3 server to monitor and record IP security cameras. I have a number of analog cameras that I would like to get working with the same system, the idea was to install a 4 or 8 channel DVR card, the issue is this server only has PCI-X slots.

From reading information that I have found out there in the net I have come to the following concussions, is someone able to confirm this.

With a PCI-X slot I can install a PCI 2.0 card and this should work?

Thanks
Grant

found an article on it..

PCI-X is generally backward-compatible with most cards based on the PCI 2.x[1] or later standard, meaning that a PCI card can be installed in a PCI-X slot, provided it has the correct voltage keying for the slot and (if inserting into a 32-bit slot) nothing obstructs the overhanging part of the edge connector. Originally the PCI bus was a 5-volt bus. Later, in PCI Revision 2.x, the PCI bus was a dual-voltage interconnect. In 3.0 this was changed to 3.3 volts only. The PCI-X bus is not compatible with the older 5-volt cards but newer 3.3-volt PCI cards will work in a PCI-X slot.[1] Apart from this, PCI and PCI-X cards can generally be intermixed on a PCI-X bus, but the speed will be limited to the speed of the slowest card. For example, a PCI 2.3 device running at 32 bits and 66 MHz on a PCI-X 133-MHz bus will limit the total throughput of the bus to 266 MB/s. To get around this limitation and the voltage compatibility issue, many motherboards have separate PCI-X channels that can be dedicated to different PCI hardware families if needed, allowing for better backward compatibility while maintaining higher total system bandwidth.

in other words.. yes(usually) but it may cause slowdowns if other pci-x cards are on that bus.

and since the slot is big some funky pci cards may not physically fit correctly.

Great thanks for your reply.
