Small, Medium or Large network

English Network/Internet

Hi, I would like to know how many computers and servers are there in a Small, medium or large network category?, what is the maximun number of guest servers recommended for a NFS shared storage?

Thanks

I am not sure there is a hard definition (like number-of-conneceted-systems>N).

Also “network” is a rather wide interpretable. The Internet is a network (a large one I would say). Your local home LAN (with maybe only two IP addresses: PC and router) is one (small I would say). And medium is everything in between??

I am not sure what you mean with “guest servers”.

NFS has servers (that is were the exports are) and clients (that is where the mounts are done).

Every Unix/Linux system can acomodate both.

I suspect that, you’re asking about Blocks of Address – in the case of the IP v4 private addresses – 24-bit or, 20-bit or, 16-bit – Class A or, B or, C …

Depends on the throughput you are wishing for and, the disk-farm associated with each NFS server …

  • And, NFS servers are never “guests” – the NFS clients can be regarded as “guests” but, they’re not – they’re clients …

Yes, yes, I know – the holy deity based in the U.S. West Coast state of Washington and more specifically the area of Redmond, often attempts to re-write the definitions made by the UNIX® world and, it looks as if, we’ll have a long struggle to prevent the permeation of such unhealthy attempted changes …

Back to the NFS I/O throughput issue – the results of serious scientific investigations into NFS performance are available from the University of Michigan and, the Linux Documentation Project –<http://citi.umich.edu/projects/nfs-perf/results/cel/write-throughput.html&gt;

[HR][/HR]Bottom line – the performance figures achieved by any specific installation will depend on –

  • The I/O throughput of the disk-farm associated with each NFS server …
  • The I/O throughput of each internal I/O bus within each NFS server …
  • The I/O throughput of each network interface associated with each NFS server …
  • The I/O throughput of the network associated with each NFS server …
  • The I/O capabilities of each NFS client …
