How to ensure the separation of data from different types of data for ESXi 4?

Does anyone have a reference architecture to ensure the separation of the point of creating data in transit and storage of different types of dataexample PCI DSS data (personal credit card), data ITAR/EAR, etc.  Concern is due to the mix of data VLAN or crossed, VLAN themselves not to use as a security boundary.  VMware offers to ensure the separation at the application levelif I read it correctlywell in transit even in stockdata must be separated.  Suggestions?

Hello VMwear8,

The chances of anyone to play with the hypervisor itself is actually quite thin, what must be addressed is the data accessed in virtual machines. If you need protect administrators to access these data.

Right now that is not possible to 100%, however you can restrict access by implementing different controls:

(1) execute all access to your ESX hosts and vCenter via the HyTrust appliance, this is a preventive measure in some cases.

(2) turn off the navigation data store in the vSphere Client (this is a RBAC vCenter)

(3) turn off 'root' or superuser for each ESX host (except in a situation of "break the glass"). If they need access 'root' follow it via sudo.

(4) add the audit in order to know who did what, when, where and how

(5) protect your management tools as if they were gold. Check out this post performance and security management in the virtual environment tools as an aid to help with this.

At most you can only put controls around the problem, we can not currently permanently prohibit access to one person give you access as being able to connect as root in the ESX host.

  • How to select the cluster/resourcepool data store?

    Hello

    as you know others my son, I'm working on a workflow to create several identical virtual machines on a VC-cluster.

    At this time a virtual computer is created like this:

    task = vmFolder.createVM_Task( configSpec, vmCluster.resourcePool);
    

    Context is being filled with the configuration of the virtual machine. vmCluster is a workflow input parameter and contains the cluster.

    It works well, but I still have to specify the data store to store files on a different input parameter, because the cluster has several shared storage units.

    Note also that our clusters have only a single pool of resources, the default.

    Let the user select a data store is not a very nice solution because of possible errors and mistakes (the user can select the local drive of the VMHost, lack of space on the storage selected etc..). But I, as a developer, also can not predefine the storage to use (several storage units, unit of different names etc.).

    Now, what I've been thinking about (and trying to implement) was to get the vmCluster data warehouses or the resourcePool, check if they are put in place for the virtual machine files and if they have enough space for the virtual machine.

    I know how to check the size and which storage are to be used for virtual machines, but I don't know how to get out them of the cluster/resourcepool.

    Can someone help me with this?

    Thank you and

    Concerning

    Andreas

    PS: Is it just me or I really make things complicated with orchestrator here?

    Hi Andreas,

    One way to get the value of storage of data is to use VcSdkConnection.getAllDatastores

    For more information, see here: http://www.vmware.com/support/orchestrator/doc/vco_vsphere41_api/html/VcSdkConnection.html#getAllDatastores

    Personally, I have not played with it, but it seems very powerful.

    There is discussion on the use of xpath in such a case in this topic (to get the value of VMs): http://communities.vmware.com/message/1673575

    Other than that you could:

    -use VcSdkConnection.getAllClusterComputeResource (gets all clusters) or VcSdk.getAllResourcePools

    -in case you work with clusters - each cluster's data store property that returns an array of data for this cluster warehouses

    -in case you use pools of resources, you must check that is the parent of each resource pool and get its data warehouses.

    Kind regards

  • Best practices for the handling of data for a large number of indicators

    I'm looking for suggestions or recommendations for how to better manage a user interface with a 'large' number of indicators. By big I mean enough to make schema-block big enough and ugly after that the processing of data for each indicator is added. Data must be 'unpacked' and then decoded, for example, Boolean, binary bit shifting fields, etc. The indicators are updated once / sec. I'm leanding towards a method that worked well for me before, that is, binding network shared variable for each indicator, then using several sub-vis to treat the particular piece of data, and write in the appropriate variables.

    I was curious what others have done in similar circumstances.

    Bill

    I highly recommend that you avoid references.  They are useful if you need to update the properties of an indicator (color, police visibility, etc.) or when you need to decide which indicator update when running, but are not a good general solution to write values of indicators.  Do the processing in a Subvi, but aggregate data in an output of cluster and then ungroup for display.  It is more efficient (writing references is slow) - and while that won't matter for a 1 Hz refresh rate, it is not always a good practice.  It takes about the same amount of space of block diagram to build an array of references as it does to ungroup data, so you're not saving space.  I know that I have the very categorical air about it; earlier in my career, I took over the maintenance of an application that makes excessive use of references, and it makes it very difficult to follow came data and how it got there.  (By the way, this application also maintained both a pile of references and a cluster of data, the idea being that you would update the front panel indicator through reference any time you changed the associated value in the data set, unfortunately often someone complete either one or another, leading to unexpected behavior.)

  • Select the most recent DATE for identification.

    Hi all

    I need to SELECT records with the most recent DATE for each code. A DATE range is part of the selection criteria.

    My data.

    1052476 30 JANUARY 09

    The code below works fine when you select 1 ID in the subselect, but with several ID he always selects rownum = 1 (of course). As far my mind takes me.
    SELECT my_id,
    my_date
    Of
    (SELECT my_id,
    my_date
    FROM my_table
    ORDER BY DESC my_date

    WHERE rownum = 1
    AND * {color: #ff0000} my_id = 1052476 {color} *.
    AND TO_CHAR(my_date,'YYYY/MM/DD') BETWEEN ' 01 / 01/2009 ' AND '' 2009/01/31;

    If I could somehow pass the ID SELECT in the subselect WHERE clause I should have done this.

    Any suggestions?
