Hi experts, i just order a server, which the mother board have spec as below and would think to go colocation:

IPMI       

    Support for Intelligent Platform Management Interface v.2.0
    IPMI 2.0 with virtual media over LAN and KVM-over-LAN support
    Nuvoton WPCM450 BMC

Network Controllers       

    Intel® i350 Dual Port Gigabit Ethernet
    Virtual Machine Device Queues reduce I/O overhead
    Supports 10BASE-T, 100BASE-TX, and 1000BASE-T, RJ45 output
    1x Realtek RTL8201N PHY (dedicated IPMI)

LAN
       
    2x RJ45 Gigabit Ethernet LAN ports
    1x RJ45 Dedicated IPMI LAN port

as i am newbie. have plenty of question on it.

Since the colocation provider have supply me an rj45 line - to use the IPMI feature, do i need need 2 RJ45 line? one for bandwidth line, one for remote ipmi?

if i have 2 server. do you advice me to get a switch? so i just connect one rj45 to the switch and split 4 connection to the server. Any inexpensive switch recommend?

You need at least two Ethernet ports per server.

Do you get charged by the port?  If so, it may be less expensive to by a inexpensive 8 port switch (plan for growth).

However, just realize that if you get a switch all your servers are going to share 1 port on the colo's switch so your bandwidth to/from the servers will be shared for all ports you have.
For colo sites where power outlets and space can be premium, I've used USB powered switches fitted inside the case
