We're currently using Exchange 2003 but should be going to 2010 in the next few 
months.

In terms of performance, a single server should do the job, so that leaves 
redundancy.

I'm interested in peoples experiences of things like vSphere Fault Tolerance

2010-09-07 Thread Paul Hutchings 
Not supported or "doesn't work and liable to screw things if you try
it"?

 

If it's the latter I guess I'll change the question to which HA
technology people are going with?

 

I knew HA wasn't supported but wasn't aware Fault Tolerance wasn't.

You have to keep in mind that Fault Tolerance in VSphere is still restricted to 
one processor and that's not going to change anytime real soon. If you need 
high availability (which it sounds like) then that's readily available .I was 
at VMWorld and they were very noncommittal on timeframe for multi-processor

OK let's start again J

 

Assuming two separate location sites with good ethernet connectivity,
both with vSphere, the primary location with vSphere Standard (possibly
Advanced depending on some other things) on at least two hosts with dual
physical CPUs what would you do to make what is, in performance terms, a
single box Exchange server more robust?

Just went down this road with a large design I had to do with a customer.  What 
I did is have two MBX servers, that will be placed on separate vSphere4 servers 
and all HA\DRS\Vmotion features turned OFF for those two virtual instances.  
Created a DAG between the two and allocated appropriate disk space per VM and 
we are rocking and rolling.  I would *love* to test VMotion win this setup, as 
I don't think the virtual instance cares where it lives... just to *see*.

That's what I don't understand tbh - why the server/exchange should know
or care about any HA/vmotion stuff happening to the VM it's sitting on
given that (presumably) a hardware failure on a physical exchange server
could cause some pretty funky problems for it to have to cope with?

Not hot spare as in automatic failover or anything, that's overkill for
us, but the plan (not just Exchange but in general) is to replicate at
SAN level between sites and have a vSphere box at the spare site that
could mount the replica LUNs and give us basic functionality in a bad
situation.

 

A DAG between two VM's in the primary location should still deal with
database corruption as I understand it, seems you almost have to decide
between host resilience (HA/FT) or database consistency resilience
(DAGs)?

RE: Exchange 2010 on vSphere - Redundancy?

2010-09-07 Thread Robinson, Chuck 
FT only supports single CPU VMs. Probably not a good fit for Exchange 2010.
HA with DAG works, but not supported by Microsoft. Ask your VMware reps about 
benefits and case studies.

If you're licensed for and using SRM, there are some pretty compelling DR 
solutions available.

Just went down this road with a large design I had to do with a customer.  What 
I did is have two MBX servers, that will be placed on separate vSphere4 servers 
and all HA\DRS\Vmotion features turned OFF for those two virtual instances.  
Created a DAG between the two and allocated appropriate disk space per VM and

RE: Exchange 2010 on vSphere - Redundancy?

2010-09-07 Thread Simon Butler 
I now have three sites where I am replicating Exchange out to a data centre 
with DAG.
All three key roles are on the same server, so it is being done with two 
servers. The FSW is on another server (a domain controller).

I have had reason to failover on one site, and while the databases went over, 
there was a problem with the clients. This was to be expected, as the CAS array 
was pointing to one server only. I wasn't do a NLB CAS Array over the WAN. 
However a quick change on the DNS and the clients reconnected. Of course if the 
WAN went, then the local clients would continue to operate correctly, because 
nothing has changed for them.

Windows 2008 R2 Enterprise, Exchange 2010 SP1 Standard, all in vSphere 4.1. The 
sites are connected on a site to site VPN.

What I also do is have all email come in through the data centre server. This 
means that in the event of the main Office going down, the email is being 
delivered to a server I control.

Simon.

RE: Exchange 2010 on vSphere - Redundancy?

2010-09-07 Thread Michael B. Smith 
No, the intent is that you use a single technology for both, as Chuck and Simon 
alluded to.

If you want to use vSphere plus DAG - then you look to VMware for support. 
Microsoft won't support that configuration, just as they don't support Quick 
Migration plus DAG on Hyper-V.

DAG is a perfectly workable HA/FT solution, as well as a consistency solution. 
So are various other mechanisms supported by third parties, such as EMC, 
VMware, and NetApp.  Pick a solution and stick with it.

Not hot spare as in automatic failover or anything, that's overkill for us, but 
the plan (not just Exchange but in general) is to replicate at SAN level 
between sites and have a vSphere box at the spare site that could mount the 
replica LUNs and give us basic functionality in a bad situation.

A DAG between two VM's in the primary location should still deal with database 
corruption as I understand it, seems you almost have to decide between host 
resilience (HA/FT) or database consistency resilience (DAGs)?

Are you talking about having a hot site in the second location for failover? 
That's a job for Site Recovery Manager. Tuning Exchange depends on number of 
mailboxes, Public folders, Full outlook (cached mode) versus OWA and how those 
resources are managed/used.

RE: Exchange 2010 on vSphere - Redundancy?

2010-09-07 Thread Michael B. Smith 
Because Exchange knows what happens to I/O's that it controls.

If an I/O aborts or times out during a vmotion (or whatever) what is Exchange 
supposed to do? Exchange (actually ESE, the Exchange database engine also used 
by AD, DHCP, etc.etc.etc.) knows a great deal about hardware errors and over 
the years has become quite adept at handling them. An additional layer of stack 
removes a lot of that knowledge - thus, you hand that level of support over to 
the solution vendor.
