Different block size in the same cluster

Hello

We use vSphere 4.0 U1. The size of the block of our VMFS data warehouses is configured as 1 MB.
We plan to add a new datastore with 2 or 4 MB, my question is:
Is it possible to configure different block sizes in the same cluster without damaging the VMS and without affecting
vMotion, SVMotion, FT, vDR, I/O performance, clone the virtual machine in another data store, deploy a VM in the data store different block size... etc?
If it's ok then all limitations or disadvantages should we pay attention to?
I have'nt found any document concerning the present and hope you guys can shed some light on this subject.
Thanks in avdance.

It is not question of having data with different block sizes stores - the only thing you need to keep in mind is the size limitations of different file between the block sizes - so you won't able to svmotion a virtual machine if the VMDK sizes are both great.

  • Can I create different consistency nodes in the same cluster with defferent?

    Can I create consistency different nodes in the same cluster with defferent cache - config.xml file?
    A cache can be distributed in these nodes of deffirent?

    Yes. You can create different consistency nodes in the same cluster with cache files - config.xml defferent as long as you use the same file tangosol - coherence.xml and the same file tangosol-coherence - override.xml. But you can't store the data in the cache in the various nodes (created with different cache-config file). In other words, a node only to create their own Hide modes that are launched with the same cache file - config.Xml.

    See the following demo:
    I start a cache using the cache config examples-cache file server - server.xml. Then I start a console cache storage-disabled people (client cache) by using the config file coherence-cache cache - config.Xml. Two of them using the same file tangosol - coherence.xml and the same file tangosol-coherence - override.xml.
    The cache server uses a cache service PartitionedPofCache. But the client side using the Distributedcache service. The cluster address is same 224.3.5.2.
    The name of the cluster is also samme. They know.

    There was a problem creating the destination folder. If please check the permission of folder or choose a different folder.   What that means, tried to name several different folders, but still the same error message. Would be grateful for the help!

    This means that the folder you want to create is blocked because of file permissions. The drive or folder you are trying to create the destination folder is set to read-only, and your username does not have write permissions.

  • Why I have two different execution plans for the same query on two different servers

    Hello everyone.

    I need your help to solve the problem quickly.

    In a nutshell, we have two servers that have the same version of Oracle RDBMS (11.2.0.4 EE). One of them for purposes of development and another is a production one.

    We have therefore two different execution plans for the same query executed on both servers. The only case of execution is OK and another is too slow.

    So I have to slow down the work of query using the same scheme to explain that young.

  • Let me know scenarios when different virtual machines with the same UUID are created in VMware Hypervisors?

    Let me know scenarios when different virtual machines with the same UUID created in VMware Hypervisors, aside from editing the .vmx file?

    The only other way I've seen is when you manually copy the virtual machine to another location on the data store (or another data store) and then when turn on/off the virtual machine, select I moved, rather that I copied it (the default option).  This will keep the same UUID.

  • different text color in the same line for staticText ScriptUI?

    is it possible to have different text color in the same line for staticText ScriptUI?

    for example, I don't want red color for the word 'RED' text below in the SAME line.

    var l is new window ('dialog', 'Sélection');.

    var s = w.add ('statictext', undefined, "It's a RED pen");
    w.Show ();

    Thank you!!

    Simple,

    var w = new Window ("dialog","Selection"),
         g = w.add('group'),
         s1 = g.add('statictext', undefined,"This is a"),
         s2 = g.add('statictext', undefined,"RED"),

  • Can you have v4.1 and v3.5 hosts in the same cluster?

    Can you have v4.1 and v3.5 hosts in the same cluster?  Before that I have to try, I thought I would check.  It would be only temporary until all hosts are upgraded.

    > Yes, 3.5 and 4.1 can coexist.

    But they can be managed vcenter 4.1 only, and you must leave the old license server for 3.5 hosts.

  • Different people I have the same address.

    I have a table with columns ADDRESS DISPLAY_NAME, Startdate, Enddate, and ACCOUNT. I need sql to find different people living at the same address. Someone help me please. Thank you.

    Hello

    Welcome to the forum!

    Use the COUNT function to see how many times an ioccurs from the given address and displays only those of a COUNT > 1.
    You can use the COUNT aggregation function or the analytical COUNT function, like this:

    WITH     got_address_cnt     AS
    (
         SELECT     x.*     -- Or list whatever columns you need
         ,     COUNT (*) OVER (PARTITION BY addrress)     AS address_cnt
         FROM     table_x   x
    )
    SELECT       *
    FROM       got_address_cnt

    I hope that answers your question.
    If not, post a small example data (CREATE TABLE and only relevant columns, INSERT statements) and also publish outcomes from these data.
    It's a good idea to do so whenever you have a problem. It allows you to specify exactly what the problem is and allows people to test their ideas.

  • 3 different comboboxes that share the same dataprovider

    Is it possible to have separate such FilterFunction for each other without having different 3 of dataprovider if I have 3 different comboboxes that share the same dataprovider?

    Well, you have to build different data providers. For example,.

    var sharedSource:Array = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];

    var dp1:ArrayCollection = new ArrayCollection (sharedSource);

    DP1.FilterFunction = function(o:Object):Boolean {return int (o)< 5;="">

    var dp2:ArrayCollection = new ArrayCollection (sharedSource);

    DP2.FilterFunction = function(o:Object):Boolean {return int (o) % 2! = 0 ;};}

    var dp3:ArrayCollection = new ArrayCollection (sharedSource);

    DP3.FilterFunction = function(o:Object):Boolean {return int (o) > 6 ;};}
