We have several DELL servers run under CENTOS 5. I check server spec and found some servers expansion slot say PCIE and some say PCIE generation 2.
My questions are:
1. does PCI express meaning PCIE 1.0???
2. does PCIE generation 2 same like PCIE 2.0???
3. what is speed on following:
PCI X4: PCI X8:
PCI generation 2 X4: PCI generation 2 X8:
Thanks.

it means they didn't specify.

probably. ask the marketing droids that wrote that. the formal name is PCI Express Base 2.0 specification
- what is speed on following:
http://en.wikipedia.org/wiki/PCI_Express#History_and_revisions
PCI-E 1.x is 2.5GT/s and 250MByte/sec burst transfer per lane.
PCI-E 2.x is 5GT/s and 500MB/sec burst transfer per lane.
4 lanes are capable of 4 times that, 8 lanes, 8 times that, but each lane can function independently, and its up to the card and its driver software to dettermine how to utilize the lanes.
