RE: How much Bandwidth?
It's called Against the Law if I expose HR data that way. Thanks for playing. Some of the crud they send should be via links to the intranet, if only I could get it to work as well as Exchange does. But then again, I don't run the intranet... -Original Message- From: Precht, David [mailto:[EMAIL PROTECTED]] Sent: Saturday, June 01, 2002 3:01 PM To: MS-Exchange Admin Issues Subject: RE: How much Bandwidth?

RE: How much Bandwidth?
Whay back when Exchange was just coming out, the number batted around was 30 LIGHT users (that is the old stress test definition) could be supported on a 56Kb link. Now that was 30 LIGHT users, with nothing else going on across the link, no file transfers (other than in mail), no web surfing, no telnet, nada. You may want to bump that to 128 Kb as a minimum. 512 Kb should work okay with 20 users, as long as they aren't shipping 15 Mbyte PowerPoint presentations with their mail. I doubt that Microsoft has (or ever will) come out with a ironclad statement that says X amount of bandwidth will support Y number of users. There are too many factors that can get caught in the mix. John Matteson; Exchange Manager Geac Corporate Infrastructure Systems and Standards (404) 239 - 2981 Defeat is a state of mind. No one is ever defeated until defeat has been accepted as a reality. To me, defeat in anything is merely temporary, and its punishment is but an urge for me to greater effort to achieve my goal. Defeat simply tells me that something is wrong in my doing; it is a path leading to success and truth. --Bruce Lee -Original Message- From: Ambrose, Joseph [mailto:[EMAIL PROTECTED]] Sent: Friday, May 31, 2002 11:18 AM To: MS-Exchange Admin Issues Subject: RE: How much Bandwidth?

RE: How much Bandwidth?
Heheheh unfortunately, we're not. I think so many of us are quite used to making so little work so well. We've got a few remote sites with 5 users riding a 128kbps line with 32k CIR. That seems to have worked just fine. We see a avg throughput of 70kbps per second. I haven't really gotten the opportunity to try and flood that line with MAPI clients, but I think we could handle a few more. It all comes down to how long people are willing to wait. So long as the line is stable... it's all a matter of time. When people ask me "will it work?" I tell them "Sure... it WILL work... but probably not the way you want it to." Throw out that disclaimer... if they go ahead with it and it's not enough... you covered your 4$$ and they'll eventually get tired of the waiting and up the line speed. Or maybe they wont... but hopefully you won't be the one on the slow link...

RE: How much Bandwidth?
One other issue you may want to look at is the anti-virus client on the workstation. Many of them are MAPI aware so when the client get the new mail notification it goes and checks the new mail for an attachment and if one exists it may download the attachment and scans it for a virus. Where you can really get banged is when someone sends a larger attachment to those 20 users in one location and all the clients are trying to bring the attachment local to scan at the same time. I've seen bandwidth utilization spike hard and the clients "lock up" while this is being done. -Original Message- From: Ambrose, Joseph [mailto:[EMAIL PROTECTED]] Sent: Friday, May 31, 2002 11:48 AM To: MS-Exchange Admin Issues Subject: RE: How much Bandwidth?

RE: How much Bandwidth?
My network here used to look like 2 cloud t1's from my WAN, with 48 out of the cloud to offices. The network was 2,000+% over subscribed but was still able to support >10 Mapi connections at each office. The big but here was that we were running PST's at that time. I since have it down to 500% over subscribed and have moved most users to the store off of there PST's. And things seem to run fine. What else will come over this 512k line? Is it 512k Burst or CIR? When you say ALL of there servers is when it sounds tricky. --Kevinm KMAP-SR, M, WLKMMAS, UCC+WCA, And Beyond http://www.daughtry.ca/ For Graphics and WebDesign, GO here! -Original Message- From: Ambrose, Joseph [mailto:[EMAIL PROTECTED]] Sent: Friday, May 31, 2002 8:18 AM To: MS-Exchange Admin Issues Subject: RE: How much Bandwidth?

Re: How much Bandwidth?
Much better explanation... You probably won't. How much of that bandwidth is available? As a rule of thumb, you need between 3 and 5 MB available per user. For 20 users, you should be just fine.

RE: How much Bandwidth?
I know that problems between servers can occur if the bandwidth between them falls below a certain number. But if you are talking about clients, sending, receiving, and syncing, then I really don't know that there is a minimum. I have a salesman who routinely connects at 9600. His Modem is broken, and he refuses to send it in, he enjoys bitching at me to much. He doesn't seem to have any problems at all, except it takes him forever to do anything. When Northpoint went under, and we lost our DSL, we had a Webramp combining three 56K dialup lines, and everyone was using that, including the field people to dial in, and they never had any problems, and I saw some of them connect at 2400! But seriously it will use as much as it can, some people who use Broadband to VPN in have hooked up at 10,000,000! That's was RAS admin says any way, but I have seen them download large 10 Mb files in less than 3 minutes. So I would say get as much as your budget will let you get.

RE: How much Bandwidth?
It can work over as little as a 33.6K link (I've not tried less). Give it more, and it takes it up to the transmission capabilities of the link and CPUs involved. -Original Message- From: Ambrose, Joseph [mailto:[EMAIL PROTECTED]] Sent: Friday, May 31, 2002 9:44 AM To: MS-Exchange Admin Issues Subject: How much Bandwidth?
