Setting Up and Administering an HP-UX NFS Diskless Cluster
Setting Up NFS Cluster Hardware

A local file system can hold a user’s home directory. Using the
standard naming conventions, such a file system would be mounted
in the client’s root file system at /home/ username . File access on a
local disk is faster than access over the network.
• Swap files
By default, clients use swap files in their /paging directory in their
private root on the cluster server’s disk. In addition or instead, a
client can swap to a disk that is directly attached to the client. This is
called a local swap. Swapping to a local disk is faster than swapping
over the network.
NOTE Each client of an HP-UX NFS diskless cluster requires a minimum of 44
MB of disk space in the cluster server’s /export directory tree,
calculated as outlined in the following table
:
Table 10-2 Calculation for a Cluster Server’s /export Directory Tree
Client’s private root /export/private_roots/client: 30 MB
Client’s kernel directory /export/tftpboot/client: 14 MB
Total space per client in /export: 44 MB
