Should we the DRS and VMotion for tolerance fault? Small cluster host 3

Hello

I'm slightly confused on some information coming from two different directions. We are in the stages of buying a package of Vsphere Essentials Plus and intend to build a 3 host with shared storage cluster. VSphere essentials plus the package comes with HA which, from my understanding, fail over automatically and restart the virtual machine on the available server. In case of server failure Vmotion or DRS provides something more than HA.

We are told that VMOTION & DRS moves virtual machine of FAILURE to an available server without restarting the virtual machine. I don't know how that's possible, but I wanted to check first with the community.

VSPHERE 4 ESSENTIALS PLUS seems ideal for small host deployments 3 @ $2 600 however, that same lic. for the regular VSPHERE enterprise is $2 800 per CPU that @ 6CPUS is more than $17 K.  Then why should we spend $17 K for business verus a $2 600 essentials more lic for such a small deployment?

Thank you

Yes, this is a new feature. http://www.VMware.com/products/fault-tolerance/

It may work on the existing links, but it is recommended to have dedicated interface for FT.

  • Change the PowerCLI Script to use the DRS and DRS storage

    Hello

    I have a PowerCLI script that specifies a host and a data store to create a new virtual machine, which has served us well. Now we have activated the DRS and DRS storage and I wonder what to change in order to take advantage of these features. Are there commands to specify a cluster and the cluster data store and let the DRS to decide the initial investment for a new virtual machine? At the moment we put all hosts and the warehouses of data as variables and use them in the line below.

    Thank you.

    $newVM = New-VM-name $NewVMname - VM $TemplateName Datastore - $datastore - VMHost $vHost - confirm: $false - location $myName

    You set a Datastorecluster?

    If Yes, then you can replace the value of parameter data with the datastorecluster object store.

    Replacing a VMHost with a cluster is not taken in charge I'm afraid.

    But you can use something like this

    New-VM-name TestVM Datastore - DSC - ResourcePool (Get-Cluster-name mycluster |) Get - Resourcepool - name of resources)

    This will automatically select the VMHost.

    The virtual machine appears in the root of the cluster.

    DSC is the name of a datastorecluster in the cluster mycluster

    I have copy of old tbird and seamonkey e-mail files with the files and emails for each. I need to add to new tbird install. can not find a way to do it. HELP PLEASE. previous e-mail files are under mail then mail.earthlink* .net and each of the five mail .net is an email address I have. I can't find a way to identify each file by email to the specific email address (IE mail.my E-mail name.net) so I can copy the files and emails from the past to the email addresses now under tbird. previous installed e-mail identities may not be the current configuration of e-mail files in tbird. I think that I must be sure that mail.name.net matches the previous mail.name.net to be able to copy and paste the old to the new. is there a way to find the file name correct the old email and correspond to the new? all my emails very important information are mostly in the old mail electronic id and must be available in the identification of email again (but same) how can I do this?

    just has got rid of the virus and responsible for all the disks but given the wifi does not work

    Hello

    Check with the system manufacturer or the actual WiFi device manufacturer and ask in their forums (if any)
    for problems known.

    Actually, try updating your driver:

    Control Panel - network - write down of the brand and the model of the Wifi - double click top - tab of the driver - write
    version - click the driver update (cannot do something that MS is far behind the pilots of certification). Then
    Right click on the Wifi device and UNINSTALL - Reboot - it will refresh the driver stack.

    Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.

I don't know if it's a question based on my computer or on the HP site. Can someone help me?

    Hi rbafkis,

    Welcome to the HP Forums!

    I would like to take a moment and thank you for using the forum, it's a great place to find answers. You have the best experience in the HP forum, I would like to draw your attention to the Guide of the Forums HP first time here? Learn how to publish and more.

    I understand that you are unable to download the software and drivers for your HP computer.

    The HP site seems to work very well as I just downloaded on it without problem.

    You are able to download from other sites?

    Have you tried using another browser to download?

    Have you tried running The HP Support Assistant to retrieve updates?

    Have you checked your firewall and virus checker setting to make sure it is not blocked?

    It could also be a firewall on your router setting.

    Have you tried to download from a hotspot or maybe a friends house?

    If you are unable to download the software desired, try another computer to download on a USB and then install the updates.

    After installing the updates, you have the same problem?

  • Cannot install the drivers and software for HP Deskjet 5650

    I removed most of the HP entries to my printer from the Start Up. Since then I have not been able to get the Printer Wizard to start. Recently, I uninstalled everything related to the printer from Add Remove programs. Since that time I tried to install my HP drive. It comes up with the error that the software does not support my operating system. My operating system is Windows XP Home Edition SP3. The software is looking for Windows XP. I downloaded the drivers and software from HP. When it runs, it starts very well. For some reason, it isn't detecting my printer. After you select how the printer is connected to the computer and the connection at the same time the software tries to finish, but he comes up with an error and says it cannot complete the installation. I am able to install the drivers, but when I try to install the drivers and software is when the error appears. How can I fix? It would be nice to use the wizard for printer hp again.

    I found the solution to my problem. Before I could install the software and drivers for my printer that I had to remove completely all the software and the printer driver. Here's what I used to delete the printer driver. Restarting my PC after removing the printer driver has been the most important step. Everything works fine now.

  • Retrieve the tasks and events for a Virtual Machine

    Hello everyone.

    This question may seem trivial to some people here, but I cannot make it work: I would like to use VCO to retrieve the tasks and events for a specific virtual machine (IN parameter). Can someone help me to do?

    Best regards

    As I said, it must create a collector by using the createCollectorForTasks method in VcTaskManager.

    The parameter of this method is an instance of VcTaskFilterSpec, in which specify you the object to filter (in your case, the reference entity VM)

    You will get a VcTaskHistoryCollector which can only be traversed by using the methods readNextTasks and readPreviousTasks.

    // Get TaskManager service
    var sdktm = vm.sdkConnection.taskManager;
    
    // Create FilterSpec containing vm reference to filter
    var filter = new VcTaskFilterSpec();
    var spec = new VcTaskFilterSpecByEntity();
    spec.entity = vm.reference;
    spec.recursion = VcTaskFilterSpecRecursionOption.self;
    filter.entity = spec;
    
    // Create collector
    var collector = sdktm.createCollectorForTasks(filter);
    collector.resetCollector();
    
    // Browse all pages returned by collector (10 entries per page)
    var taskPage;
    while ((taskPage = collector.readPreviousTasks(10)) != null)
    {
        for each (var task in taskPage)
        {
            System.log("Task: " + task.name + " -> " + task.startTime);
        }
    }
    
  • Research in the LocalStorage and sessionStorage for app

    Hi all

    a few newbie questions...

    I'm looking for in the localStorage and sessionStorage for app.

    -basically I'll be getting data from an external base and want to store locally for a time and also update.

    I think for my purposes, it may be preferable to simply store data temporarily - similar to a session var - and dump the data after the closure of the app - and then reloading all when they connect each time.

    Then it would be better to use the localStorage and sessionStorage for this purpose?

    In my test of localStorage data remained persistent even after that I quit and reloaded the app - which is nice but it's better for me to be able to remove it when I want to?

    Are there functions that can erase a few pairs of key / value?

    Are there functions that can remove all local storage?

    Is localStorage / sandbox with an IOS or android app sessionStorage or it is also available outside of the app?

    You use your developer tools? You can easily see what is stored in the local storage and under what domain name.

    In Google for example simply tap Menu-> tools-> Developer Tools (or CTRL + SHIFT + I) and then go to the tab "resources"-> storage room (down arrow roll), find the area. You can see what exists between the pages.

    More generally, if data are not defined on the same domain, or if you accidentally delete your local storage, this is when it gets dry it. Make sure you understand how to define and work with it properly without crushing. You use a framework by any change? If so, there are probably a few tools to manage all of this for you.

  • Would it be possible to have 2 shared resources, a local containing all common topics and photos for several projects and another a remote control containing all the topics and pictures for the purpose of collaboration

    Hello

    I was wondering, now that I discovered the benefits of eating of the resource, if it would be possible to have 2 shared resources, a local with common themes and images for several projects and another one, remote, containing projects together, i.e. the subjects and images, for collaboration purposes.

    The only local, I intend to use it for my purposes to have common points (topics & photos) update of all projects where they appear and the distance that I intend to use it with remote colleagues, who might want to make changes in the topics.

    This would mean that the topics and current photos will be present in the resources, one local as one remote.

    Thank you.

    SVN is not a source control package?

    RoboHelp comes with RoboSource Control that could be used to provide the source code control. But if you already have a package in place, my thought is why reinvent the wheel? Simply use what is there.

    What are the advantages and disadvantages for the largest and the smallest block size block size?

    Smaller size of block

    Benefits
    Relatively large GoodHas air space due to metadata
    (i.e. block the header).
    Not recommended for the outline. He could only
    be stored for each block, or worse, a few lines line
    If one line does not fit into a block, for small lines with a lot of chance of chaining
    access.
    Reduced block contention.
    Disadvantages
    A relatively large air space due to metadata
    (i.e. block the header).
    Not recommended for the outline. He could only
    be stored for each block, or worse, a few lines line
    If one line does not fit into a block of chaining.

    Larger size of block

    Benefits
    Lower overhead, so there is more
    room to store the data.
    Allowed to read a number of lines in
    the buffer with a single I/o cache
    (according to the size of line and block size).
    Good for very large or sequential access
    lines (for example, LOB data).
    Disadvantages
    Waste of space in the buffer cache, if you
    random access to small lines and have a large block
    size. For example, with a size of 8 KB block and 50
    size byte of the line, you will lose 7 950 bytes in the buffer
    When you make a random access cache.
    Not good for the index used in an OLTP blocks
    environment, as they increase the claim to block
    on the leaves of index blocks.
