RE: Exchange 2010 Design Questions
Pretty sure it's that the various sizing calculators from Microsoft always base figures on physical/actual number of cores. When you introduce HT, you're not really giving yourself double the number of CPUs in raw performance, so any planning based on the calculators goes out the window. We disable it on our servers, but only as the recommendation.

http://blogs.technet.com/b/jeff_stokes/archive/2010/09/15/to-hyper-thread-or-not-that-is-the-question.aspx The issue with HT is that, since it is scheduled as separate processor, but doesn't have unique cache assigned to it, in certain memory intensive operations it can cause reduced performance.

Re: Exchange 2010 Design Questions
Thanks for the responses. I can appreciate the technical reasoning that Michael pointed out, but I'm also curious if this reasoning holds true with current Westmere or Sandy Bridge chipsets. In regards to the recommendation from Microsoft, it comes across as if they don't trust the person implementing Exchange to know their own hardware. Almost as if they picture someone opening task manager and determining they have 24 processors because that's how many they see. Anyway, thanks again for the insight. I believe our hardware configuration provides more than enough processing power for our environment so we'll probably just stick with the recommendation. - Sean On Thu, Sep 6, 2012 at 5:26 AM, Michael B.

RE: Exchange 2010 design
Ah. We've got some F5 gear too (not mine to touch) but they were too pricy for this project. Kemp's on the approved list too, and the price was right. Our network guy opened a case with them asking about one arm vs. two arm setup. fairly basic but we wanted to do it right the first time. Quick to respond, right on time with the explanations and answers. Documentation (for me anyway) was nice, setup is straightforward, they're working as advertised. Maybe it's the same with all of them. I don't know- this is my first hands on with these hardware bits.

RE: Exchange 2010 design
We went WNLB for a couple of reasons- $ and it was supported happily for our size/needs. Pretty sure it still is but MS doesn't seem to like it nearly as much as they used to-I'd guess based on real world experience? Today, those size/needs would steer towards HLB. IIRC it was a pain for us to set up and get going properly- whether that was WNLB, me, or just all the #$^! that was going on at the time, I dunno. Once it was going I guess it LB's well enough as long as all the boxes were up. not that it was a regular occurrence by any means but if we lost/had to reboot a box it did screw with all the connections on that box. Had to fiddle with patching too (drainstopping etc) but so it goes. Also unless we missed something obvious, the only health checking you have is basically a ping test, HLB goes past that. Stuff I've done resulting in 0 client complaints- Pulled power on the active Kemp Rebooted a CAS Powered down CAS My other response in this thread I rated at .0002 Paul Cents. This one I'll rate at a full .02 PC- Given you're going there anyway, get the network guys to make their decision and skip WNLB altogether:) Paul From: sms adm [sms...@gmail.com] Sent: Friday, June 17, 2011 4:35 PM To: MS-Exchange Admin Issues Subject: Re: Exchange 2010 design How reliable was your WNLB?

RE: Exchange 2010 design
That looks like a good paper, and the solution looks appropriate. One thing to make sure you're aware of when using NLB; you can't have NLB and Windows Clustering on the same server. So if you are using NLB for your CAS and you think you may want to use DAG for your mailbox server(s), the roles will have to be on separate servers.

RE: Exchange 2010 design
I downloaded and read that and it seems pretty substantial and seems to cover the main points. I would expect if you followed it diligently you would end up with a working and supportable solution. It also explains fairly well what the key points of an Exchange design are and is pretty clear on where you can and can't make compromises. The solution in the paper is quite neat. It gets round the four physical server issue by using two servers with virtualization. I think this will also save you cash as a Windows Server Enterprise Licence (which you need for the clustering to build the DAG) allows you to run up to four copies of windows in the same physical machine. However you still need four Exchange licences (but even for a big config only two need to be Enterprise). I note the paper skirts round this. However there are however some tools available that simplify the some of the calculations I found (but didn't try) these:- http://www.ibm.com/partnerworld/wps/sizing/sizingguide/guide_redirect.js p?guide_id=sgq71003253131900102ssoId=unauthenticated http://h71028.www7.hp.com/ActiveAnswers/us/en/sizers/microsoft-exchange- server-2010.html http://blogs.technet.com/b/exchange/archive/2009/11/09/3408737.aspx Hope this helps Dave Wade Corporate and Support Services I.C.T. 0161 474 5456 From: Laurence Bryant [mailto:l...@cem.dur.ac.uk] Sent: 17 June 2011 16:55 To: MS-Exchange Admin Issues Subject: RE: Exchange 2010 design Thanks for the replies, they set me off on a lot of reading. Unfortunatly I've been told that a hardware load balancer is out of the question at the moment, but I did find this link for a highly available 500 mailbox design (http://www.microsoft.com/downloads/en/details.aspx?FamilyID=e0e93251-fc 04-4a18-8aa0-23817b6d0c97) in my list archive, for an MS white paper which seems to describe an implementation that would fit with what I've been required to do. My only question would be, how real world are these white papers, if I followed a similar route would I end up with a practical solution?

From: Damien Solodow [mailto:damien.solo...@harrison.edu] Sent: 17 June 2011 17:24 To: MS-Exchange Admin Issues Subject: RE: Exchange 2010 design That looks like a good paper, and the solution looks appropriate. One thing to make sure you're aware of when using NLB; you can't have NLB and Windows Clustering on the same server. So if you are using NLB for your CAS and you think you may want to use DAG for your mailbox server(s), the roles will have to be on separate servers. It has a neat solution to that. It uses four virtual servers on two physical boxes.

Been running E2010 for a year now- We're getting rid of WNLB, putting four Kemp loadmaster 2200's into place, a high availability pair in each AD site Did one site yesterday, the other is planned for next week.We're ~7K mailboxes with 2 real mbx/hub and 3 virtual cas in each site. ~1400 BB's, few hundred EAS devs. Are you stuck on F5 for some reason?

RE: Exchange 2010 design
Laurence, If you're going to have all three roles, CAS/HT/MB, on each server, you need a hardware load balancer. You can get a decent one for under $2k. If you go with the CAS/HT role on one server and the MB role on the other, you won't have any fault tolerance other than any level of RAID you may use.
