Except where specifically noted, the terms Diskless PC, Diskless Workstation, Diskless Terminal and Thin-Clients, device, network PC, thin client, and appliance are used interchangeably.
A diskless PC is defined as a computer without any local storage media, i.e. no floppy or hard drive. Normally a diskless PC depends on a LAN-based boot server to provide the operating system from which the diskless PC can boot. A diskless PC also requires a network adapter interface and boot ROM (also known as boot PROM) to communicate with the boot server. The process of booting a diskless PC or terminal is known as remote booting or network booting (LAN boot). Some of the more popular methods of network booting include RPL, BOOTP, DHCP and PXE. The boot ROM that you choose will depend on the protocol on your Local Area Network (LAN). For example, the RPL network boot protocol is generally only possible on a LAN where the NETBIOS or NETBEUI protocol is used. On a TCP/IP network infrastructure, you can choose between BOOTP, PXE or DHCP.
Diskless PCs offer several advantages over traditional workstations in the area of manageability and security.
- No moving parts, so they are less susceptible to dust, noise and vibration.
- Hard disk or floppy failure is no longer an issue.
- Less security risk since no data is stored locally.
- Easier to replace than traditional workstation – no OS and/or software re-installation is required.
By choosing the Argon Managed PC Agent with multi-protocol support out-of-the-box, you will have a Boot Agent (boot ROM) that works with whichever network boot protocol you choose to implement.
