Introducing Netbench - HP ML570 - ProLiant - G2 Tuning Manual

Novell NetWare 6 performance tuning guidelines for ProLiant servers
introducing
NetBench
You can download the 30-day evaluation version of the Intel client VTUNE at
developer.intel.com/software/products/global/eval.htm
The NetWare component (vtune.nlm) can be downloaded from Novell at
developer.novell.com/support/sample/tids/topt2/topt2.htm.
The performance results presented in this document are based on the current version of
NetBench. NetBench is a licensed Ziff-Davis media benchmark program that measures the
performance of file servers as they handle network file I/O requests from LAN attached
clients. It uses LAN attached clients to generate repeated file I/O requests to a server.
There are about 18 application program interface (API) routines in NetBench executed by
each client in the test mix. Each client tracks the number of times the calls are executed
and how long it takes to execute each call. As a result of these I/O request activities, the
throughput scores and the average response time performance data are recorded. The
results are then used to gauge how well the server can handle the file I/O requests
generated by the clients. For more information about NetBench and on how to obtain a
free copy of NetBench, visit:

The 18 API routines NetBench executes are as follows:
open file
read
write
lock
unlock
get file attributes
In real-world, the I/O pattern and characteristics for a typical file I/O-type application is
different from that of a client/server or web-type application environment. In a file and
print environment for example, all requests are generated and sent from the clients to the
file server for processing. The main goal of the server is to move data between the clients
and the server as quickly as possible. During this process, the subsystems that endure
intense pressure are:
network
memory
disk
NetWare 6 has several tools and utilities for monitoring the performance of the above
mentioned subsystems. The major ones include:
NetWare Monitor
NetWare Remote Manager
Vtune
It is therefore prudent to regularly monitor the subsystems in order to identify potential
bottlenecks in your operating environment. Typically, the processor is not the main
performance bottleneck in a file and print environment, but regular monitoring should not
be ignored.
