Diskless
Diskless refers to computer systems that operate without a local hard disk or other persistent storage. In a diskless configuration, the operating system and most applications are loaded over a network from centralized servers at boot time, and runtime data may be kept in memory or on remote storage. Diskless clients are common in environments such as computer labs, classrooms, high-performance computing clusters, and thin-client deployments, where centralized management and easy re provisioning are advantageous.
Booting and operation typically rely on network services. A client uses a network boot protocol like PXE
Technologies and configurations commonly involved include PXE or iPXE, DHCP, TFTP for boot files, and NFS or
Advantages of diskless systems include reduced hardware costs, simpler mass provisioning, and centralized management of images
