Size of the LUN Max size minimum and maximum RDM?

The Maximums on 4.1 Configuration seems to have been a change in the size of the LUN max, of the strange 2 TB - 512 bytes to just 2 TB. Can anyone confirm that it is correct in 4.1? As I understand it in 4.0, if you got your logic unit number created to exactly 2 TB, you have lost about 500 GB of space (?).

It would be interesting to know if it is "fixed" in 4.1 and if only the use of 4.1 hosts then 2 TB LUNS could be created?

In addition, the maximum size of RDM always seems to be 2 TB - 512 bytes in 4.1. What is the reason for this kind of limit? If the guest operating system can accept more large drives of 2 TB, which need not enough?

Even on the store of NFS, the maximum size of virtual disk to a virtual machine will be 2 TB - 512 bytes?

Yes, there is a maximum specified for the virtual machine.

Would a connection iSCSI comments launched a LUN liked work of 2 TB (if the guest operating system can handle)?

Yes, it's a way to work around the limitation of current 2 TB - 512 bytes.

The information about this change in the passage of Q & A at the end of TA7121 - ' next generation VM Storage Solutions with API for integration (VAAI) Array vStorage "was held in San Francisco just a couple of weeks.

Interesting. Did you get any sense if this possible change should come an update for 4.0 - 4.1 or may appear in a future version, 4.5 or 5.0?

I will attend at Vmworld in Copenhagen in October, so maybe I should visit this session.

You know, I don't really have a strong impression be it on this issue.  My stomach seems to tell me that it will be in the next version of main product.  If I remember correctly, one of the presenters of the session was one of the engineers who worked initially make VMFS.  This session was really good, so I recommend anyway.

  • How can I change the minimum and maximum values on a map of metrics.

    Sorry, I'm new to vCOPs and it drives me crazy.  I searched the community and Google, but found nothing so thought I'd post here.  I am interested in a VM in vCOPs and select operations - tab the metric.  I add the CPU usage | Use (%) to the table.  By default, the y-axis is has a low of-40 and a maximum of 60.  Well, my % of the CPU usage never goes below 0% right?  It's hard to look at this figure.  Also, I like to see usage to 100% as a maximum rather than somewhere just above where is the top of the chart.  Looks like there should be an easy way to change the minimum and maximum y, but I can't seem to find it.  Can someone show me what I'm missing here?

    Thank you

    Bob

    He does. There is no way to force it to a specific axis. For vC Ops, there is no concept of a "desired" min and max for Y axis in respect to the display by the metric system settings type. All the data is dynamic and can be any value graphically speaking.

  • Two text fields each other also have the values of the minimum and maximum fields?

    I have two text boxes that are mutually exclusive: one is a dollar amount per pay period, and the other is an annual amount in dollars. User can enter an amount in the box of one or the other (but not both), and I used the validation for this below script:

    Field1 script:

    If (event.value) this.getField("Field2").value = "";

    Field2 script:

    If (event.value) this.getField("Field1").value = "";

    Now, I also Inow the field limit with the minimum and maximum amounts for these same fields. But, because the range of field values is an option button other than the custom validation script, it seems that I can't do both because I can choose only one option button:

    Screen Shot 2015-11-02 at 1.25.44 PM.png

    Is there a way to keep my custom validation scripts so that they are mutually exclusive, but also to impose minimum and maximum amounts for these areas?

    You must validate the range using a script.

    It will look something like this:

    if (event.value) {
        if (event.value<10 || event.value>100) {
              app.alert("You must enter a value between 10 and 100.");
              event.rc = false;
        } else this.getField("Field2").value = "";

  • ScheduledThreadPoolExecutor with minimum and maximum thread

    Hi all

    I need to implement something that is planning a number of potentially important small tasks over time. I would use a pool of threads to do this in an effective manner. I wish to have a configuration, for example, 1-10 of discussions where the threads are created as needed and if the number of threads max is reached, tasks are queued. The tasks are timed and repeat if I prefer the automated programming of the executor. The deployment environment and the number of tasks to manage will vary so adaptation of configuration and execution is important. When there is no work, I would like to scale down over time as well. Here is my small tent to reach a suitable with competition from Java API design...

    Now, looking at my options, it seems that ScheduledThreadPoolExecutor is a good match for my needs. So what I would like to implement is a mechanism to define the minimum and maximum number of threads that are created for the thread pool. I understand that it is the number of threads of"base" and the maximum number of threads in the java.concurrency terminology. However, I struggle to create what I would.

    It seems to me that the ScheduledThreadPoolExecutor is always created as a fixed size thread pool. So I can't set that I would have say minimum of threads 1 and a maximum of 10. There is the setMaximumPoolSize() method, I can call on the executor, but he seems to have no effect. If I create my own ThreadFactory, and use that to give me track when new threads are created, create a ScheduledThreadPoolExecutor with one set of threads 1, fixed the limit 2-wire and plan a set of 6 ongoing tasks in loops, it never starts higher than 1 threads. So it seems that it completely ignores the setMaximumPoolSize().

    There is the option to call allowCoreThreadTimeOut() and setKeepAliveTime() on the executor. When I look in the code of ScheduledThreadPoolExecutor, I also see that he prestarts always all discussions until number of threads core set when a task is scheduled. So even if I got the coreThreadTimeout and keepAliveTime for work, attributes that can not help me because it would always just he hike up base number. Otherwise maybe I could use that have a 0 min and max of the number of"basic". Or is the coreTimeOut for some other purpose?

    Well, the question of the "base" here is, is it possible I could create an executor who creates a number dependent threads according to the need (between x 1 and x 2 that I would define, for example, 1-10) but achieved x 2 at the start of the queue of tasks that come? It seems that the whole API is to assume I want either a fixed number of threads with the unbound queue or an unlimited number of threads with a queue bound. No way to have a set bounded discussions with min and max thread bodies, as well as the queue without terminals when the max thread count is reached? And can I get that with ScheduledThreadPoolExecutor enough, please?

    Or maybe I'm just the idea of simultaneity just bad here for somewhere? Is a kind of best practices of competitive access to pigs immediately the maximum number of threads, you think you might need later conflicts of resources? This is why there is only the size of the "fixed"? In all cases, ideas and help is appreciated.

    Well thanks for reading this far... and all answers of course!

    Yes, this particular scenario is difficult to achieve, and Yes, it seems that the standard behavior for me as well. You can sort of achieve this effect by using the feature "allow core of timeout threads. Basically, build you a pool of 'fixed' size with a queue boundless, but the flag 'allow the kernel thread timeout' set to true. This will essentially give you what you want, except that the 'min' size is 0. This seems to be a reasonable compromise to me because you do not need to write custom code (I had already implemented a scenario you describe, a queue of unlimited blocking which 'lies' to be full until the maximum pool size is reached).

    example:

            ThreadPoolExecutor executor = new ThreadPoolExecutor(maxPoolSize, maxPoolSize,
                                                                 60L, TimeUnit.SECONDS,
                                                                 new LinkedBlockingQueue(),
                                                                 threadFactory);
            executor.allowCoreThreadTimeOut(true);
            return executor;
    
  • Each scale minimum and maximum for each slide table slides

    Hello

    is it possible to set values mini/maxi different scale in a group of slides via property nodes? As far as I know that's not possible. All the slides in the table must have the same minimum and maximum value. I only find a way to change all the scales at the same time. Are there any other ideas?

    Thanks in advance

    LVW

    Hi lvw

    You are right on the table, it is not possible to have different scale values. If you don't have a small number, you may be able to use a cluster of sliders, then you can set each individually. You can use the table for cluster and cluster to table to convert data types. You can also use cluster control references to define each level individually.

  • Change of minimum and maximum voltage that we expect to generate/measure

    Hello!

    Our application has a FOO and one task of tension HAVE with digraph maxVal + 10 and-10. We acquire/generate n times m samples (for a total of m * n samples). It is possible to reconfigure the digraph/maxVal each of the n times (according to the samples generated/acquis) in a quick way? If I'm not mistaken, it is possible, by stopping and recreating the task (by calling DAQmxClearTask, then DAQmxCreateTask and finally DAQmxCreateAIVoltageChan or DAQmxCreateAOVoltageChan), but as far as I know it is a slow operation and is not a good thing for our application. Are there other ways to do it? In fact, we use the NI PCI-6229 map.

    Thanks in advance!

    Hello

    It is possible to set (and also get) the minimum and maximum values for a channel DAQmx: in LabVIEW property DAQmx channel analog input nodes: Maximum values and Analog Input: minimum, in textual languages with features DAQmxSetAIMin, DAQmxSetAIMax (and similarly for the AO channels).

    However, for the boards of the M series it is not possible to set these properties when the task runs, so you will need to stop the task, set the new values and restart the task.

    I hope this will help!

  • the LUN max size

    Hi all

    We ordered a new EMC SAN. The capacity is 9 to. Now, we want to create a single LUN with all the 9 TB. I read something about booking SCSI problems on large LUNs. On this LUN must be running 40 VM in the future with the DB Applications.

    Concerning

    Thellier

    OK... it's here... I think you're talking about measurement of the disk. Suppose you have a small 20 GB Lun with the VMFS file system. You can do that a larger VMFS volume by measurement of the disk. Go to the properties of the LUN data store, there you will find an option to add raw LUNS in your present data store so that your only VMFS is stride across multiple LUNS. I hope that this time, I have read your query straight :-))...

  • Initial size (MB) and maximum (MB) size should I use to add more RAM to my memory?

    I followed the instructions on a video on how to add more RAM to your computer without taking it apart.

    I followed all the steps up until I came to the part in the dialog 'virtual memory '.  Where it says, 'custom size' you have to put the ' initial size (MB) and the ' size maximum (MB).  How do I know what size to put in this area?

    I looked up my information on my computer:

    Windows Vista Edition Home Premium

    Memory: 1.00 GB

    System type: 32-bit

    Now, while I was following instructions to add more RAM.

    my computer displays this information:

    in the performance option dialog box:

    In the tab advanced under virtual memory, it is said:

    "page for all readers file size: MB."

    In the virtual memory dialog box:

    for the C: drive:

    There's the initial size (MB) - white

    and (MB) maximum size - White

    What should I do in this case?  What would be the initial size and maximum size?

    Hello Palette,

    You talk about 'virtual' non-physical memory. There is a difference.

    UPN based on the amount of RAM 'physical' you have in your machine the ' virtual RAM should be of approximately 1.5 hour of Aries. You have currently 1 GB of physical RAM Windows allocates already 1.5 GB RAM virtual and, frankly, it is better to let Windows manage the virtual memory file.

    If you want to improve then install the physical RAM more. Your guide to computer manufacturers will tell you to what maximum physical RAM, you can install and what type it is. I admit that I have changed the physical RAM to many times so know what I'm doing, but, frankly, it's less of a hassle to change the physical RAM which play with virtual RAM.

    RAM memory modules simply slide in and are cut in place. Change the RAM in a desktop computer is easier than a cell phone, but you will get much better results increase the physical RAM that you would changing virtual RAM.

    Of course, this is assuming that you need in the first place of the increased RAM. I recently increased my physical RAM of 4 GB to 8 GB and hardly noticed any difference.

  • What are the minimum and maximum of a competing request ID numbers

    Hello

    I was wondering where the concurrent request ID start for example 0,1, or 10000 and where they "check". For example, is it to 9999999, 99999999 or higher.

    I have a feeling they start with four or five digits may be 1000, but I could not find a direct reference in the manuals or on the Support website. I don't think that the maximum size of the FND_CONCURRENT_REQUESTS table's history, but can be a problem.

    Oh, I mean a 11.5.10.2 instance in my case, but would be interested in the case of the 12 too.
