capacity of new server
|
|
| Chuck Preston Jr. 2005-04-07, 5:50 pm |
| Hi list,
Can anyone estimate how many simultaneous streams I could expect my new
server to reliably deliver? I will be streaming recorded video
averaging 120Kps per stream with the 90-Day Unlimited Capacity Pack. My
server is a P4 Xeon 3.00Ghz dual processor with 2Gigs memory and
Gigabit NIC.
The reason I'm asking is that I've got a client that wants to make sure
that we can stream to an unlimited number of users. In other words, we
don't know how many users to expect (hundreds? thousands?) So I want to
tell him how many streams I can handle with the server I have and the
unlimited capacity pack. Then, if that's not enough, we can consider
buying additional servers and licenses.
As a side note, I know I could hire one of the big hosting companies
but I'd really like to do this myself. I've been hosting a bunch of
recorded video from a smaller server for the last couple of years with
no problem but I've never done anything this big.
Thanks,
Chuck

| I imagine anyone answering this question will need to know the Mbps
throughput of your server. If your server is only capable of 12.5Mbps
then the capacity pack won't do much more for you than the Pro license.

| Well, I am no expert on such conversions, and there is probably some
variability based on application, but with a gigabit NIC card on a
high end server that is designed to really deliver a gigabit of
throughput, you can probably get the better part of that gigabit in
transfer rates, meaning roughly dividing your gigabit connection by
the size of your stream.
Of course if you actually do the math, that comes out at about 8,300
streams. Now one issue is how many streams the actual processor can
handle. At some point, processors bog down with context switching. Now
you have two processors and lots of cache with the XEON, but 4000
simultaneous users per processor and 8000 total connections to the
machine is alot.
So I guess my point is that throughput will not be nearly as big an
issue as connections. With one process you could comfortably deliver a
gigabit stream. But the smaller the slices you create, the more
overhead the processor has to handle to deal with the separate
streams.
I would love to hear if anyone knows what the max number of real
streams FCS can handle for a given 2 or 3 ghz processor.

| Hi Simon. Thanks for responding.
I'm embarrassed to admit that I haven't got a clue what the Mbps
throughput of my server is. I thought the limiting factor is the speed
of the NIC connection, which is 1000MBps. What else factors in? The
server is brand new with 3 Seagate Ultra320 SCSI drives, Adaptec RAID 5
controller, Windows server 2003. Is there anything else I need to
report?
Thanks again,
Chuck

| Chuck,
Memory! Flashcom really likes memory when you do high numbers of streaming.
I'm not really aware on memory-consumption with more than 1000 simultanious
streams but W2003 Standard can handle 4GB so I suggest you use all that if
you want te be prepared for high numbers...
Kind regards,

| Hey Chuck, as Hank pointed out there are other limitations such as
connections to worry about other than bandwidth. My point goes back to
the unlimited pro license you have, the unlimited license means that
the only limitation will be the server's Mbps limit (IE, how much data
you can directly toss onto the internet, not *locally* through your
GiGE network) coupled with the massive number of connections which Hank
described quite well.
I dunno, call me crazy, but running the unlimited license on just 1
server may be overkill. You'd probably get more bang for your buck
with load balancing across 4 servers (based on your previous comment
about *thousands* of users) then dropping back down to 1 when the 90
license runs out.
My understanding of all this is limited, I worked at www.max-t.com as
an illustrator for all their network guides so what I know about
networks comes from that yr long contract.

| Thanks to all you guys that responded. I've got a lot better picture
now of what I'm dealing with. I'll let you know how it turns out.

P. S. Special thanks to Simon for the illustrations and to Chris for
the answer to world peace.
