 |
|
Hi,
I was recently looking at Dell servers and note their recommended config
is two sockets - with Quad core in one and Dual in the other.
Obviously this is somewhat non-symmetrical?
Any idea why they would suggest this layout, as opposed to two Quads or
two Duals?

Do you have a URL for that ? I'd at least like to see the
context of the statement.

There are several reasons I can think of. All of them would be poor design. The BIOS might not support two quad cores. The OS might support only six processors. There might not be enough power for two quad cores.

Please control your output line lengths (fixed here). They should
not exceed 72, but 67 is better. Also please do not top-post (not
fixed). Your answer belongs after (or intermixed with) the quoted
material to which you reply, after snipping all irrelevant
material. See the following links:

Do you have a blue flashing light in your hat? The only posts I have seen
from you lately are repremanding people for bad grammar, the wrong line
length or top-posting. Whilst I agree with your comments, it is becoming
very irritating! |

Hi Paul,
The reason there's no URL is because my Dell site is a secure site for
ordering, but I can explain how to get to a similar page with the same
choices:
Go to the main Dell website, choose the type of "business" you want to
be, choose products, and then servers, then choose something like Dell
PE2950. Go to "Configure and buy" and note all the options you can
choose. The first choices are the type of processors you would like.
You should see some choices are in a different color and say "Dell
Recommended".

Hi Paul,
When I try to "customize" from the link you gave, it's completely
different to what I was seeing on the UK "premiere" login site, in fact
the list of processors on offer isn't even the same!
Here is a link that demonstrates the "mismatched" processor problem, but
I don't know if this link will work for you due to cookies etc. At least
this link does not need a password:
<http://premierconfigure.euro.dell.com/dellstore/config.aspx?cs=RC1050265&customer_id=RC1050265&oc=PE29501&~tgt=global_cfg&c=UK&l=en&s=PAD>
I got here by going to www.dell.co.uk, then choose "servers : medium
size business", then PowerEdge 2950, then the first "Customize and Buy"
button. They recommend a Quad Core in Socket 1 and a Dual Core in Socket 2.
Thanks for the help with this.

The description here of the PE2950, is implying matched pairs.
http://www1.ca.dell.com/content/products/productdetails.aspx/pedge_2950?c=ca&cs=calca1&l=en&s=biz&~section=specs#tabtop
And at least for me, when I "Configure" one, the two items for
processors (initial processor choice, and the "Additional Processor"),
don't have a green "Dell recommended" coloration. There is a
green band over top of the Windows Server 2003 R2 operating system
choice.
If I was spending the bosses money, I don't think I'd be caught
dead with mismatched processors :-) Certainly from a FSB protocol
point of view, I don't see a reason for a problem. The chipset
is 5000X. There is a block diagram showing the FSB connections
for the two processor sockets, are independent.
http://www.hardwarezone.com/articles/print.php?cid=2&id=2002
When I look at the 5000X Northbridge datasheet, I notice there
is one clock (CORECLK) which looks to be used by both processor
busses. So mixing FSB speeds doesn't look like an option. If a dual
and a quad shared the same FSB speed, maybe that would work.
But I wouldn't take any chances, and would match them.

Hi Kony,
The Premiere login (referenced in my original post) requires a password
at the FIRST page, you can't give a URL "just before the order".
Most of the Dell site will only work when you're in the correct country
and when you have cookies already in place, for example when I click
your second link below it just gives an error saying the Data cannot be
found, probably because I'm in the wrong country and don't have a cookie
in place.

You could have at least linked right up until the point
where it became an order if you couldn't get any further
link to work.
http://www.dell.com/content/products/productdetails.aspx/pedge_2950
For the benefit of others, a link to what was suggested
above is here,
http://configure.us.dell.com/dellstore/config.aspx?kc=6W300&oc=becwfk2
Do you have a URL for that ? I'd at least like to see the

It looks like it was just a misunderstanding of what
"recommended" means, since Dell has no idea of the use and
it was just a generic default choice on an add-on menu, most
likely they had it recommended prior to offering quad core
and merely forgot to change that "recommended" field to be
updated to dual vs quad.
In summary, remember that you need to know what you want to
buy or it is likely someone else should be placing the
order. A web page is designed and updated by humans, is
subject to errors at any moment. I would expect that even
if it had allowed buying one quad and one dual core, someone
would have caught the mistake before it shipped and would
have contacted the OP to determine if it should have 2 x
dual or 2 x quad CPUs.

Hi,
I managed to get confirmation from Dell UK. The website is "wrong". It
lets you choose processor pairs that don't match.
It seems their web designers are not capable of programming
combinational logic into DHTML. Apparently, there's been quite a few
complaints!
Since posting here, and trying out URLs for other countries and other
business "sectors", I can now see they (Dell) change the rules quite a
lot depending on who you are and where you live.
