I assume that what you are asking is "what does 'server deployment' mean?". In other words, you want to know what it means to deploy a server.

It means to bring the server into operation, to make it operational. In practice this means installing and configuring the requisite software to make it work as required.

"The SmartStart Scripting Toolkit radically simplifies high volume server deployment by delivering a hands-off, unattended installation and configuration solution"

"Altiris Deployment Solution software offers enhanced Dell server deployment capability that dramatically reduces the time and cost of provisioning and managing your Dell servers. Deployment Solution uses pre-built scripts to quickly and easily deploy Dell servers from bare metal. Deployment jobs enable you to update and configure hardware and system settings (including BIOS, RAID, and DRAC configurations), deploy a Windows or Linux OS, install applications (databases and e-mail servers), and more—all from a central, remote console.

This illustrates the fact that "deployment" in this context essentially involves installation and configuration of software.
