HP Smart Array P600 -- 337972-B21, why is it that G5 doesn't come with 64bit PCI slots?

[BOYAN BIANDOV]

Hi everyone,

I have this issue where I need to install HP Smart Array P600 -- 337972-B21 into DL380-G5. 

As you can see the P600 has 64bit PCI slot and for some reason the DL380-G5 does NOT come with any 64bit PCI slots.

So I have to get an optional raiser board which comes with 2 64bit PCI slots -- 410570-B21:

My quetsion is why? Is the 64bit so old that on the G5 HP decided NOT to include slots like that by default and hence only the optional raiser can do it or is it just an arbitrary choice by HP?

Thank you

Hey, 

From wikipedia "PCIe is a serial bus with a different physical interface that was designed to supersede both PCI and PCI-X."
