    If anyone comes to this thread looking for an answer then you are fine presenting with the same LUN ID for different hosts.

    Re: Configure Mulit-Homed Server for Muliple Physcial Network

    The physcial adapters on the ESXi host will observe networks and IP changes to which it is connected to. You can see this by going to the Configuration > Network Adapters section in the VI client. Therefore you’ll need to physcially plug these physcial network adapters into a physical switch (each).

    Re: Groups being Cached

    You may be adding users to groups via GPO?

    Loopback processing normally only applies policy settings in the computer context and ‘can’ ignore all user settings (lots of caveats to that i know)

    in reply to: Groups being Cached #237718

    Re: Groups being Cached

    I would try the following:

    – Create another user account and try and replicate the same problem. If you dont get the same issue then put it down to a nuance with that user account
    – If you still get the same issue with another brand new account then try logging on to multiple machines with the new accounts.

    If still same issue then it could be AD replication:

    – Are the machines you are logging on to in the same AD sites?
    – Different domains, etc etc etc?
    – When logging on are you authenticating with the same domain controller? (running SET in command line and looking for LogonServer can shed some light on this)
    – If you are authenticating with e.g. DC1 on the workstation but DC2 when logging on to the Terminal Server then is replication working between these domain controllers and or sites

    in reply to: adprep rodcprep Issue #237716

    Re: adprep rodcprep Issue

    I’m an idiot.

    The context of the VB script supplied by the MS article needs to changed to update the other partitions.

    i.e. this will update the DomainDnsZones:

    cscript fixfsmo.vbs DC=DomainDnsZones,DC=contoso,DC=com

    and this will update the ForestDnsZones:

    cscript fixfsmo.vbs DC=ForestDnsZones,DC=contoso,DC=com



    After i ran that the /rodcprep process completed without error

    in reply to: VM Memory Confusion/Question #237713

    Re: VM Memory Confusion/Question

    I would start by comparing the figures in the Memory section on the Resource Allocation tab on the VM itself.

    e.g.

    myvm
    Allocated: 1024MB
    Shares: Normal
    Reservation: Not set
    Limit: Unlimited

    I have attached a screenshot of what i see within vCenter for this VM.

    Of note, nothing is ballooned or swapped. What do your figures tell you?

    Re: creating a test environment from a production ESX4 cluster.

    ranjb

    VMware Converter can take copies of physical or virtual machines while they are online. Take into account network traffic though. We have successfully done this on production servers in our environment (while they were powered up).

    Cloning a VM (not to template) is essentially the same as Converter but the VM must be powered off.

    In theory taking a copy of a DC and/or your Exchange server would be fine but to get it to walk when sitting within a different network is a very different ball game.

    Its good practise to create a test network from scratch as not only does this give you a refresher in networks and AD infrastructure but it also means you have a clean ‘build’ of a domain.

    Re: creating a test environment from a production ESX4 cluster.

    Why dont you build these test VMs from scratch? Why the need to copy the production VMs?

    I presume you are having issues with copying from within the Datastore browser in vCenter? Make sure the VM isnt on (you could even remove the cloned VM from the vCenter inventory). What errors do yo uget?

    in reply to: Memory Allocation – Exchange 2007 #237705

    Re: Memory Allocation – Exchange 2007

    Following the guidelines on this page:

    http://technet.microsoft.com/en-us/library/bb738124%28EXCHG.80%29.aspx

    …and at the bottom of the page:

    Guidance and limitations similar to the Mailbox server role apply to multiple server role configurations. To accommodate the Client Access and Hub Transport server roles on the same server as the Mailbox server role, the recommended base memory configuration is 8 GB. Memory guidance based on mailbox count and profile is the same as the Mailbox server role. The recommended maximum amount of memory is 32 GB.

    All i need to know is whether Exchange 2007 will mind me decreasing RAM.

    Thanks

    Re: Why my VM creating big swap file when there is still memory available ?

    Firstly, VMware Tools is absolutely essential. Not only does it provide important monitoring and administrative tools but it also improves performance for CPU and Memory.

    Secondly, as previously stated the swap file is created when the VM is created and is subject to the amount of memory allocated (and reserved). The VM will use physical RAM available to it (from the host or the resource pool). At times of resource constraints the VM will then use the swap file (sounds like Windows!)

    As a general rule (in ESX context) any paging is bad so you’ll need to keep an eye on it in vCenter/Virtual Center by checking the Resource Allocation tab and keeping an eye on the Balloned and Swapped figures (i use vCenter so i dont know what they are in Virtual Center, if they even exist)

    This is my understanding.

    Re: Theoretical, real, and realized hardware contraints.

    Piece of string type question….

    Well, here are your configuration maximums: http://www.vmware.com/pdf/vsphere4/r40/vsp_40_config_max.pdf so there’s a start.

    You’ll probably run into RAM constraints first unless you are using heavy CPU apps on your XP boxes, then you’ll have CPU _and_ RAM constraints!

    It sounds like you have installed ESXi to a USB drive and booting from this? This is also known as ESXi embedded…. Is this correct?

    If it is then you have corruption in the USB drive.

    in reply to: Exchange and VM configration.. #237699

    Re: Exchange and VM configration..

    Best Practices and money-no-object you would create two separate Disk Groups (HP vernacular), one for log files and one for data. This would separate I/O over different hard drive spindles.

    The logs LUN would be vRAID1 for performance and the data LUN would be vRAID5+ for redundancy.

    Again, money-no-object, you would split Exchange roles between VMs. i.e. Edge on one VM, Hub transport on one, etc…

    Re: How can Virtualisatoin help us?

    If you go down the VMware route you could utilise VDI (Virtual Desktop Infrastructure)

    http://www.vmware.com/products/view/overview.html

    This can deliver desktops across the LAN (not sure about running this on megabit connections though)….very cool but expensive
