Exchange 2003 / 2010 on vshpere foundation 4.1

We are a small organization with 60 mailboxes on a physical server to Exchange 2003.  My VMWare environment consists of 710 2-Dell servers with 32 GB of ram and vmfs volume unique raid 10 on each server.  There is no SAN and this seems to serve us well, even if a San would make things like Vmotion and HA as possible, that's what we have at the moment.

Ideally I would like to move the exchange Server 2003 on a VM host and continue to use this platform for another year or two, but there seems to be problems of performance that are best addressed in the 2010 version.

Would it not possible to run Exchange 2003 on one of my servers host with the VMFS volume shared using storage for databases and log files?   What I do need to provide some physical drives dedicated for exchange databases, or is there any recommended configuration: for the virtual drives for a small exchange on VMWare Server?

From a disk I / IO perspective if you have only 60 users, I don't think that you will have problems even if you use Outlook in Mode online (as opposed to the Cached Mode).  In addition, there are a few things you should think about to / consider:

(1) Exchange 2003 is not supported in a machine virtual on a hypervisor/platform. You can't get support from Microsoft if you are running Exchange 2003 in a VM on vSphere, Hyper-V, whatever it is.  I've had clients essentially turned almost immediately without even best effort support for Microsoft.  I'm not sure of the importance of technical support Microsoft for you, but for many of my clients, the risk is not worth...  Customers choose to migrate to Exchange 2010 (or 2007 for years before) that supports virtualization complete.

Microsoft has created the program (SVVP) Validation of virtualization server to validate their applications running on virtual machines on multiple platforms.  I would check that out to see exactly what is and is not supported all the way back to Exchange 5.5 If you can believe it.

http://www.windowsservercatalog.com/SVVP.aspx?svvppage=svvpwizard.htm

(2) Exchange 2010 offers big improvements over Exchange 2003 in more than a reduction of inputs and outputs.  There are so many new features of the product that it is useful to consider migrating directly to Exchange 2010.

If you really want to virtualize it, I would follow advice from design even for physical Exchange 2003 servers.  You don't need the physical disks dedicated to the database/log, but you may want dedicated virtual disks for easy management.  In addition, you can just follow normal recommended or even existing P2V your Exchange Server.

So to sum up - Yes you can virtualize Exchange 2003 and as small as your environment, it should run perfectly, but it is not supported by Microsoft.  I would consider an upgrade to Exchange 2010 as preferred approach if possible.

  • Virtualization of Exchange 2003

    We are about to start (finally) virtualization of our systems.  One of these systems is a Standard Exchange 2003 on Windows 2003, using DAS server and serves about 600 boxes mailbox (if users concurrent max would be around 200 users).  Current physical area includes 3 disks, C, D and E.  C is for system D is application/newspapers and E is for banks to information (only 2 - public and private).

    After reading the various articles and best practices I came with a plan.  Could you get it someone please let me know if it is a good idea?

    In a test environment first of all (with DC operation), separated from the production network:

    Plan of P2V is the current physical Exchange box using VMware Converter Standalone.   Each physical disk would be converted to a virtual disk.  It will implement a SAN to shared storage iSCSI.  Thought create LUNS separate D and E drives, just don't know if this is necessary.  All Exchange and protection antiviruss services will be stopped during the P2V.  I tried to make a cold-clone, but don't know if I can due to the fact that we won't have a VMware enterprise license.

    Once that P2V is complete, power to the top of the new virtual machine.  Remove any vendor (HP Insight) specific applications and drivers.  Then, start the Exchange services and test.

    If successul, process document, repeat the test and before you run on the production system.  Once final, production VM is created, physical stop and turn on VM again.

    If you're ok with the unsupportability of the solution, then I say go ahead and virtualize it.  I still believe that deploying a new server and migrate the mailboxes are the cleanest way to do but to understand the limitations it.  All the more that I would recommend if you could back migration to Exchange 2010 rather than another server in 2003.  There is no direct upgrade from Exchange 2003 to 2013 path so you will need to go to Exchange 2010 in a first time in any case.  Might as well get ready now.

    Migration is easier because then you're not taking all issues with the server of your virtual infrastructure.  It is also pointless to worry about uninstalling the hardware drivers, of unnecessary software, etc.

    I had some success with P2V migration running on Exchange servers.  As I said earlier, you will have the best chance of success if you can organize the downtime to stop all of the Exchange during the P2V services.  That's how I managed in the past.

    Do your homework and understand what works best for you.  I'm sure you can succeed with two approaches.

    Good luck!  Feel free to come back and post how things went or if you need any help.

    A vueltas con los procesadores....
    
    Lo primero, ¿que tasa de carga tiene el procesador inicial?, si la máquina va mal con un Xeon PIII@900, el que se ejecute en un core de un X5500 no va a resolver gran cosa si es por tema de rendimiento (obiamente va mejor, pero no el doble de mejor)
    
    Si la máquina original (pongamos un DGaviion con 2 Xeon PII 300 y 256 de ram con NT Enterprise) tiene 2 procesadores, echando cuentas deberian tener 300+300 y por lo que he leido hasta aqui, un core de cualquier procesador actual debaría valer.
    La realidad es que si esa máquina (me da igual el procesador, el sistema operativo y la ram que tenga) se cambia a menor en alguno de los componentes físicos, lo lógico es que pierda rendimiento, aunque corra en un hp blade 680 G7 (4 hexacores).
    
    En principio y salvo muy raras excepciones yo siempre virtualizo 1 a 1. (en las excepciones entran los procesadores HT y solo respeto los cores en la serie P4-478) con lo que pongamos el primero de los procesadores, Xeon de PIII a 900, que en un 2003 representa 4 cores en 2 pastillas. En este caso le virtualizo a 2 vcpu y pruebo su rendimiento. En los casos en los que son xeon PIV a 2000 por ejemplo (sin HT) en 2 pastillas, se quedaría igual, con 2 vcpu.
    
    Al igual que en un ESX, el tema de las cpu en la VM es delicado porque pueden tener aplicaciones y servicios multihilo a los que el KB de microsoft no les afecta para nada (oracle es un buen ejemplo, cristal reports, GIS, y alguna mas). Y ademas, las herramientas de inventario como puede ser el capcity (de vmware o de m$) o perfmon suelen registrar poco o nada de esto ya que los servicios arrancan incluso antes que el monitorizador o el servicio wim (y no digamos que caiga una consulta en ese momento) por lo que puedes tener en apariencia una máquina física muy sobredimensionada, que al reducirla durante su virtualización caiga por su propio peso.
    
    Y dicho esto, recojo y me voy de vacaciones :)
    Ahi queda.

  • How Transport rules Exchange Server 2010 takes immediately?

    Hey guys, I meet a riddle in my daily work.

    It's rules of transport in exchange server 2010.

    I made a few rules in use. Rule A for DynamicDistributionGroup A and article B for DynamicDistributionGroup B.

    Obviously, the two DynamicDistributionGroups are the corresponding OUs. OR A and B OU in Active Directory.

    Now I move user C OR B OR A. I thought that user C will use the B rule immediately, but I'm wrong.  He uses the rule until I restart

    the mail server.

    So here's my question: How does Exchange Server 2010 Transport rules take immediately?

  • Exchange 2003 Migration to Office365 with SSO

    Hi all

    Merry Christmas to start!

    I work for a company that run Exchange 2003. We plan to do a migration to Office365 and I am researching on the best solution.

    I am aware that there are three main options available, hybrid/intermediary/putting in service.

    My instincts suggest that the best option would be to complete the migration using the staging process, but I think that if I take this route I can't implement single sign on? This is the case...

    If so, is this means to ensure single sign-on can be used, then I can only implement a hybrid solution?
