部署服务器

A deployment server, known as PXE server, is an independently specified server used for providing PXE services and console proxy services for Bare Metal chassis.

• We recommend that you deploy PXE servers independently, thus satisfying the need of the multi-MN host HA scenario and avoiding a single point of failure (SPOF) to greatly improve deployment efficiencies.
• A deployment server must be attached to a BareMetal cluster.
• One Bare Metal cluster can only attach one deployment server, while one deployment server can attach multiple Bare Metal clusters simultaneously.
• A deployment server must have sufficient storage space to save images used for PXE deployments.
• A deployment server must connect to a management network for reaching management nodes.
• A deployment server must connect to a deployment network for reaching Bare Metal chassis.
• A DHCP listening NIC on a deployment server must connect to a deployment network. In addition, make sure that this deployment network does not contain other DHCP services for avoiding IP conflicts.
• A deployment server must install the latest ZStack Custom ISO with the recommended c76 version. Otherwise, this deployment server cannot provide software packages for Bare Metal chassis via the FTP service.
