Chapter 9. iSeries NetServer File Serving Performance

This chapter will focus on iSeries NetServer File Serving Performance.

9.1 iSeries NetServer File Serving Performance

iSeries Support for Windows Network Neighborhood (iSeries NetServer) supports the Server Message Block (SMB) protocol through the use of Transmission Control Protocol/Internet Protocol (TCP/IP) on iSeries. This communication allows clients to access iSeries shared directory paths and shared output queues. PC clients on the network utilize the file and print-sharing functions that are included in their operating systems. iSeries NetServer properties and the properties of iSeries NetServer file shares and print shares are configured with iSeries Navigator.

Clients can use iSeries NetServer support to install Client Access from the iSeries since the clients use function that is included in their operating system. See:

http://www-1.ibm.com/servers/eserver/iseries/netserver for additional information concerning

iSeries NetServer.

In V5R4, enhancements were made help optimize the performance of the iSeries NetServer, increasing throughput and reducing client response time. The optimizations allow access to thread safe file systems in the integrated file system from a new multithreaded file serving job. In addition, other optimizations have been added and are used when accessing/using files in the “root” (/), QOpenSys, and user-defined file systems (UDFS). See the iSeries NetServer articles in the iSeries Information Center for more information.

Workload

PC Magazine’s NetBench® 7.0.3 with the test suite ent_dm.tst was used to provide the benchmark data3.

2The clients used 100 MB Ethernet and were switched into the 1 GB network of the server.

3The testing was performed without independent verification by VeriTest testing division of Lionbridge Technologies, Inc. ("VeriTest") or Ziff Davis Media Inc. and that neither Ziff Davis Media Inc. nor VeriTest make any representations or warranties as to the result of the test.
