What is the difference between Network Boot and FTP Boot?

[astanislaus]

I am referring to the following link:

http://www.cisco.com/en/US/docs/app_ntwk_services/data_center_app_services/css11500series/v8.20/configuration/administration/guide/Offdm.html#wp1069939

It says in here -

•Boot via Network - Allows you to boot the CSS using FTP from CSS software on a network-mounted file system on a remote system

•Boot via FTP - Allows you to download an ADI file containing CSS software that you want to install on the CSS disk (hard or Flash disk)

•Boot via Disk - Allows you to boot the CSS from software currently on the CSS disk (hard or Flash disk)

•Boot via Clear - Instructs the CSS to boot the CSS from the secondary boot record

In Network boot ,the CSS software installs on a network-mounted file system on a remote system Instead of the CSS disk

while in FTP boot,

the CSS software installs on a CSS disk(hard disk or flash disk ) instead of the remote system.

In Network boot if the CSS has a disk failure a network boot allows the CSS to boot independently from its disk and to load the configuration into memory.

but there are some limitations as network boot is not supported on UNIX workstations.

in both case the software is copied from FTP server. But in first case it is instslled on the remote system hard disk and in the second case it is installed on a CSS hard disk.
