DL380 - network detected as 100MBps not 1Gbps

dear,

 

I just bought new server DL 380 G8, and use gigabit switch from HP too.

 

just curious, why status on network show 100Mbps for speed, not 1Gbps?

 

thanks

Are you looking at the iLO port, or is the server powered off at the moment?

 

Keeping up a gigabit link takes more power than a 100 Mbps link. When the server is powered down and the NIC is kept active only for the Wake-on-LAN functionality, the NIC can switch down to 100 Mbps speed to save power. When the server is running, unconfigured NICs might also be completely powered down, or in a 100 Mbps low-power state.

 

(That might actually be a compromise between the current strong trend to save power in order to be more eco-friendly, and the convenience of having the link LEDs light up to confirm a good cable connection as soon as a cable is plugged in, even if the NIC is not configured yet.)

 

Likewise, an iLO interface might be 100 Mbps only, as there is not much need for higher speeds with the iLO.

Hi,

 

I'm use other Port beside iLo.


from the beginning (when I turn on the server), until log-in, LAN speed still 100 Mbps.

I tried to wait half hour, but speed still same.

 

Is it ok, if I set the speed to gigabit (via hardware properties)?

 

thanks.

Hi.

 

Is the switch managed or unmanaged?

If it's managed, have you set the port as auto?

 

Have you tried using a different cat6 / 5e cable?

Damaged shielding on the cable can cause issues with the detected speed.

 

Cheers

Hi,

Is there any ways to bring the NIC down/up with the server?

When server power on, NIC should be up. When server power down (or shutdown OS), NIC should be down.
