Hi,
I have had a few problems with our attached tape drive and I thought I would just double check which slot should hold our SC11xe HBA.
The site for the card is
http://h18004.www1.hp.com/products/servers/proliantstorage/adapters/sc11xe/index.html and it says the Host Interface Supported is PCI-Express.
We are putting it into a DL380 G5. http://h18004.www1.hp.com/products/quickspecs/12477_div/12477_div.html At the minute I have the card in slot 2. I am not sure if I have the standard or optional riser. How can I tell? Regardless of which one I have, which slot would I plug the card into?
The more I look at the quickspecs the more I think it should be plugged into a 64-bit/133MHz PCI-X slot. Should it?
And I don't have any idea what the difference is between PCIe and PCI-X.
Not sure if it matters but running Windows 2003 x64 Standard.
Thanks
Nathan

overview about PCIe - PCI-X
""
The PCI-X spec is already outdated as far as new and future systems go. In fact, some of the changes made to PCI through PCI-X have only made some of the inherent limitations of PCI worse, not better. PCI-X doubles the clock speed and bus width of the PCI bus, but the actual performance gains yielded from this PCI-on-steroids approach are nowhere near what they should be. The reason: The higher speeds also made the bus more sensitive to noise and crosstalk (interference from neighboring circuits), and shielding the bus from these things is an expensive proposition. (Many of the same problems with PCI-X are present in the DDR-II memory bus spec as well.)
Since PCIe was redesigned from the ground up to deal with the problems, it represents a fresh architectural approach instead of an attempt to squeeze more life out of an old design merely by ramping up speeds. If PCI-X is like a network router, PCIe is a network switch: Instead of each device using all of the bus whenever it's free (the router model), each device has its own data lane to the PCIe controller that can always run at full speed (the switch model). In fact, PCIe uses a network-style protocol to manage bus traffic, including quality-of-service provisions for devices that need it most.
The PCIe design allows old-school PCI and newer PCIe devices to run side-by-side on the same system without problems, so any older devices that might need to be migrated along to the new architecture can still run. This makes PCIe the better choice as both a short- and long-term investment. Many of the existing device classes that were offered in PCI or PCI-X implementations in the past (especially video controllers) are now being offered as PCIe as well.
One caveat: PCIe is meant only to be used as a local interconnection bus. If you're planning a system where the bus is meant to support external connections as well, then something like the InfiniBand architecture might be better suited to your needs (i.e., for a datacenter, in place of Fibre Channel or a similar architecture).
