Is there a way for a single WM9 client to pull a hundred or more
streams from the server? We have server technology that we think
might increase the throughput of a WM9 server but we don't have
hundreds of clients to push the server to its max.
Thanks,
Steve

Steve:
There is a program can do what you want -- Windows Media Load Simulator
Organizations are building high-capacity servers and server clusters to
serve the increasing demand for streaming media. Microsoft Windows Media
Load Simulator version 4.0 is a useful tool for determining server capacity
and system stability during the planning and development phase of your
Windows Media server system. You can also use it to monitor the
availability and health of a Windows Media server after your system is put
into production.
Windows Media Load Simulator creates a real-world load on a server by
simulating Microsoft Windows Media Player connections; the load-test
results on the server can be viewed in a log. Windows Media Load Simulator
is designed to run on one or more client computers to simulate a large
number of client requests. If you balance the load on your Windows Media
servers for greater scalability and availability, then Windows Media Load
Simulator should be run against each individual server.
Windows Media Load Simulator can also monitor a Windows Media server in
active service, and it can be configured to automatically alert an
administrator when server performance begins to degrade or if the server
stops responding.
Visit the web site
http://www.microsoft.com/technet/prodtechnol/netshow/downloads/loadsim.mspx
and download loadsim.exe from there.
Hope this helps, thank you for using Windows Media Services

Re: client simulator |

I read through the Windows Media Load Simulator documentation but this
simulator seems to force all the simulated clients to stream the same
file, so there's virtually no load on the server's storage system or
on the ability of the server to manage requests that go all over the
platters. In fact, the server could just cache this one file and
operate from memory, clearly NOT a real-world VOD environment. Did I
miss something in the documentation or is this truly a limitation of
the simulator? If this is how it works, does anyone know of a
simulator that does allow each simulated client to access it's own
media file?
Thanks,
Steve

Steve,
You can specify multiple files in WMLoad simulator. From
what I remember, if you have 10 different files specified
and you have 100 clients, then 10 clients will
approximately hit each file.
Hope this helps.

Ravi,
Yes, you're right. You can indeed stream from multiple files with the
client simulator. The documentation misled me by only talking about
putting the single WMLoad.asf file in the test directory and then
saying the simulator tests "the server and the network" without
mentioning the storage system. In any case, I have 120 files media
files now in the test directory with the simulator running 120
clients, so the storage system is getting a good workout.
Thanks for your input.
