l Users cannot directly load external hardware devices, such as USB flash drives, U keys of banking services, external hard disks, and dongles.
l Out-of-band management is not supported. Your physical server resources are managed and maintained by eSurfing Cloud.
l Hot migration is not supported. The failure of a physical server may adversely affect services. Therefore, we recommend that you deploy services in cluster or active/standby mode to achieve high service availability.
l You cannot create a raw device without OS. That is, a physical server must be pre-installed with an OS.
l You cannot customize configurations of a physical server such as CPU and memory nor expand the capacity of CPU, memory or local disk. You can only expand the capacity of an EVS.
l You cannot mount an EVS to some physical server specifications or images because they are not equipped with smart NICs or for some other reasons.
l If you choose to assign IP addresses automatically when creating a physical server, do not change the private IP address after provisioning the physical server to avoid conflict with the IP addresses of other physical servers.
l You cannot configure a bridged NIC for physical servers. Otherwise, network exceptions may occur.
l Do not upgrade the built-in kernel version of the OS. Otherwise, the hardware drive of the physical server may not be completely compatible and thus the reliability may be affected.
