if the server is end device (not like esxi or vswitch) you can enable portfast - there is no issue.
posrtfast quick way to port come up.
here is the good explanation :
PortFast
The PortFast feature is introduced to avoid network connectivity issues. These issues are caused by delays in STP enabled ports moving from blocking-state to forwarding-state after transitioning from the listening and learning states. STP enabled ports that are connected to devices such as a single switch, workstation, or a server can access the network only after passing all these STP states. Some applications need to connect to the network immediately, else they will timeout.
Enabling the PortFast feature causes a switch or a trunk port to enter the STP forwarding-state immediately or upon a linkup event, thus bypassing the listening and learning states. The PortFast feature is enabled at a port level, and this port can either be a physical or a logical port. When PortFast feature is enabled on a switch or a trunk port, the port immediately transitions to the STP forwarding state.
Though PortFast is enabled the port still participates in STP. If the port happens to be part of topology that could form a loop, the port eventually transitions into STP blocking mode. PortFast is usually configured on an edge port, which means the port should not receive any STP BPDUs. If the port receives any STP BPDU, it moves back to normal/regular mode and will participate in the listening and learning states.
In most deployments, edge ports are access ports. However, in this scenario there are no restrictions in enabling the PortFast feature. The mode of the port changes from PortFast to non-PortFast when the port receives a STP BPDU. To re-enable this feature on a port, run the shut command followed by a no-shut command at the interface/port level.
