Bandwith requirments |
|
|
Hi,
I am planning to put an Exchange server in a datacenter, but need to know
what bandwith the three offices need as a minimum to be able to work without
having speed problems.
Office1 has 6 people
Office2 has 15 people
Office3 has 25 people
I can obviously put a server in each office, but it feels like a bit of
overkill to do it.
Regards,
Martin

Not enough information to be helpful just yet. Can you provide the
bandwidth current available? Including saturation rates etc?
Also include what types of messages they send. Are they large binary
attachment-laden messages or small text only messages similar to IM?
Those make a large difference in the equation.

Today they have
Office1, 1 meg DSL
Office2, 1 meg SDSL
Office3, 2 meg leased line.
The emails consist of a combination of both attachments and pure text.
Clients also send us attachments, such as artwork, word files, excel files
and sometimes other attachments.

So what was the current line saturation levels?
Are these via the internet that they connect back or VPN from the remote
office to the corporate?
What you really need to get to is the (amount of traffic currently on the
wire - the amount of traffic expected from Outlook.) and hope that you still
have capacity left. To do that, you need to know the information for the
equation. Current traffic saturation and the expected amount of traffic
when Outlook is pulling data across the wire. You can guess by the amount of
data each email message contains (25K? 30 MB?), the type of client you'll
use (OWA, RPC/HTTP, CACHED MODE, MAPI, IMAP, POP, etc?) and then figure out
what the experience will be for each user.
In many implementations with small message sizes, I've seen DSL provide
plenty of space. In others, I've seen where fractional T-3 was barely
enough ;)

Martin,
A good way to estimate bandwidth requirement is to use 5 kbps requirement
per user, when using Outlook 2003 AND Exchange 2003, with cached mode. So in
your situation :
Office1 would require 30 kbps
Office2 would require 75 kbps
Office3 would require 125 kbps
This is a general good value based on return of experience within my
customers' implementations, however if you think you'll have real power
users, then you might consider further research on exact bandwidth
requirements.
If I were you (after reading your second post) I'd say gogogogo for
consolidation ;)
Ben.
