• Network Troubleshooting

Since NFS is an acronym for “Network File System”, it should come as no

surprise that NFS performance is heavily dependent upon the latency and

bandwidth of the underlying network. Before embarking on a detailed

investigation into a specific area of NFS, it always makes sense to first verify that

the underlying network is performing as expected.

This section will not be describing the myriad of available networking topologies

and interface cards. NFS runs on most any networking link, and it typically

performs faster on faster links. There is a wealth of information about the latest and

greatest networking technologies (such as Gigabit Ethernet, APA, etc.) available

from HP’s IT Resource Center: http://itrc.hp.com and HP’s online documentation

repository: http://docs.hp.com.

What will be described is a recommended methodology and set of tools available

for understanding the physical layout of your network, measuring its throughput,

and performing routine network troubleshooting.
