[dba-Tech] DDR Power requirements

Ya, terminal server will be somewhat of a resource hog, but newer machine
should handle it well, unless you start getting a lot of users.

IIS will run just fine on even a pentium II.  It doesn't require that much
CPU power.  Memory is good, especially if you are using ASP, and .dll's.
The more programming that puts things into memory, the more memory you use.
But plain old webpages will draw very little resources.

I was running MSDE and IIS and a low usage asp app on Win2000 and an old AMD
1.2 with 1.5 gb RAM along with my desktop and it ran OK, but it was a small
database and very low usage.

Am I wrong in assuming that terminal services will be a resource hog too?

Thanks,

Jim

Webservers are very low on the resource list.  SQL server is going to be
your resource hog.

I will be adding more drives later so that's the reason for the 550 power
supply. I hope that it will handle being a web server for one low usage app,
do low volume terminal services for 1 or 2 users, and file and SQL server.
If necessary, I could offload the web server to a hosting company. Hopefully
I won't have to add another box.

Yea, a 430 is a pretty safe bet I'd think.  Sounds like a nice system.

John,

I understand that and that's why I use Antec power supplies and cases. If
you are running all of that on an Antec 350 watt ps, then I should be safe
with the Antec 430 watt with my Neo2 Platinum, ATI Radeon 9200SE, 6 case
fans, 4 Raptors, Sony DVD burner, 4 gb DDR400 OCZ ram, AMD 64 939 pin 3500
90nm which uses about 20 watts less than the 13 micron CPU's. The floppy
drive will be removed when the RAID is up and running. I never go over the
top with video cards on systems because my systems aren't used for gaming so
that would be a waste. I do have an Antec 550 that will be installed when
the RMA is turned around.

I feel OK about loading Windows Server after hearing what you are running on
an Antec 350.

Thanks,

Jim

James,

One thing you need to understand is that all manufacturers are not created
equal.  I use Antec supplies because they are a very good manufacturer and
if they say X amps on a rail, it will do that.

Having said that, I have several systems running an Athlon64 3+g processor,
3 gb (3 one gig sticks) RAM, 6 hard disk drives, a floppy, a CDRom and a
video card.  In fact the video card is one thing you MUST be aware of, the
high end cards require enough juice that they may actually require an extra
connector to the board (and a bigger supply).  The "highest end" card I have
is an ATI 9800 which is not a particularly high consumption board.  I run
these systems on Antec 350 watt supplies.

In summary, if you suspect that you need a lot of current buy a name brand
power supply, and then go for the 400w, 450w or whatever.  Do NOT think that
a $35 500w PS is going to cut it.

Thanks, Stuart. Now I'm really confused. I just sent an email to the
manufacturer, hopefully they can shed some light on the subject. I'm
assembling a system into an Antec Performance series case that has a 430
watt power supply along with an Antec 550 watt power supply as a replacement
for the 430. I swapped out the power supplies and didn't notice that I
received an EPS power supply instead of the ATX until I tried to plug into
the motherboard. I have RMA'ed the power supply but don't want to wait to
fire the system up.

To err on the side of caution, I will just remove 2 gigs of ram and maybe 2
of the raptors before firing it up.

Tricky.
