Is vMotion road data via the server vCenter Server?

Hello

I need help to solve a query I have.

We currently have a vCenter server that manages certain clusters, but also some stand-alone hosts with local storage (not shared). Stand-alone hosts are physically located on remote sites. Some sites have more than one of these stand-alone hosts. We have an obligation to move a VM to a standalone host guest to another independent host on the same remote site.

As there is no shared storage the VM should be stopped before trying the vMotion.

The virtual machine in question has a 4 TB thick VMDK accrued that is migrated between the physical host computers.

I think when the vMotion is launched the data will be limited to the subnet that the two physical hosts are connected and therefore use the bandwidth available via local network equipment and will not let the physical site. My colleague suggested, however, that data travels through the vCenter server. Of course, this would cause a problem to try to move the data so much and would effectively mean that this 4TB would leave travel via the vCenter server, remote site, then return to the remote site. Not only this would be very slow, it could also have a negative impact on bandwidth to and from the site.

So my question is who is correct? (Assuming that one of us is!)

Thank you

When you start migrating cold from a virtual computer by selecting migrate both (host and storage) where your hosts are based in the same place, it will happen with esxi source and target host, it will not go all the way to your host to vCenter.

If your environment is vSphere client of web use 5.1 or higher, and you can move VM while it is powered on and residing in the local storage of the host. This feature is called Cross-host migration. available only by using the web client.

  • Transmission of data via the Ad Hoc network in LabVIEW

    Hello

    I'm trying to transmit some data (position, speed, etc.) a laptop computer to a host computer.

    The laptop and desktop have the card installed wireless so I thought this would be a good

    the idea of transmitting data via Wi - Fi using TCP.

    However, the problem is that there is no router/modem in the area where the laptop is sitting

    so, I create a network of Ad-hoc (computer to computer) between the laptop and the desktop computer.

    Then, I use "ipconfig/all" in the Windows command prompt to extract the IP as follows.

    IP address wireless laptop: 169.254.165.72

    IP address Wireless Desktop: 169.254.102.126

    Desktop Ethernet IP address: 129.94.229.230

    I then use the code example in the TCP library named 'Data Server.vi' and "Data Client.vi."

    I listen on port 6340 times the wireless and ethernet desktop on the side map server.

    And on the side of the customer, I opened a connection to port 6340 169.254.102.126 IP address.

    However, the connection cannot be granted. Anyone know why this is the case?

    Note: I have disabled all firewalls.

    Interesting, when 2 computers are connected to the same modem, their IP addresses

    differ only by the last number (e.g. XXX.XXX. XXX.123 vs XXX.XXX. XXX.256), but when an ad

    the House of Commons network is established, their IP addresses have 2 numbers that are different. (XXX.XXX.

    102,126 vs XXX. XXX.165.72) I wonder if this has nothing to do with the failure.

    Thanks for all your help.

    Ron Liou

    I somehow this job.

    What I've done

    -Once again set up an Ad hoc network for the labtop and Office

    -verification of the IP address is always the same

    > Portable wireless IP address: 169.254.165.72

    > Portable wireless subnet mask: 255.255.0.0

    > Wireless Office IP address: 169.254.102.126

    > Wireless Office subnet mask: 255.255.0.0

    -switch on the ICS of the ethernet on the desktop card

    (This resulted in an IP different addresses assigned beng)

    > Portable wireless IP address: 192.168.137.21

    > Portable wireless Subnet Mask: 255.255.255.0

    > Wireless Office IP address: 192.168.137.1

    > Office Wireless Subnet Mask: 255.255.255.0

    Now I use the ip address of office (192.168.137.1) to open the connection

    and it works! ??

    I am very pleased with the fact that it works but I would like to have one

    explanation on why it takes an ICS.

  • Do not find data on the server of Web pages, but do developing PC localserver

    My website access data OK on my localserver, but once I download on my server online, it cannot be found. It is there because I can access it via my ISP software.

    The error I get is - the website has encountered an error during recovery http://Bega.org.UK/gateway/graveyard/public/data/view_graves_date.php . It is perhaps out of service for maintenance or configured incorrectly.

    I'd appreciate any help on this. Try to understand me he kept me entertained all weekend.

    I looked again, and that's what I found.

    My first site was based on the original David tutorial "build your first dynamic web site. I was advised by Nancy O when DW CC dropped behaviors side server using WebAssist ones. The code mentioned earlier in this thread has been inserted in the file by WebAssist server behaviors.

    I didn't like my first site so I made a cosmetic redesign, but kept the dynamic code on the site first - it worked. Still doesn't work.

    The new site has been working properly until a week or two ago but then, for some inexplicable reason, he stopped allowing me to add or edit records. Now I can view and the list of records, as described in the tutorial of David but not add or change. This problem applies to all three databases.

    Although I saw no difference in code between the old and new files (apart from the cosmetic things) I tried to copy the code of the dynamic action from the work to those inactive files but it does not work in the new files.

    So the problem must lie elsewhere. The files in the folder connections are all correct (same as the old site) and as I said I can list all of the records and discovered the complete data of the selected, both paths to the files, and the user name, passwords and the information contained in the files in the folder of connection should be OK.

    So, what's the problem? Where should I look? I'm getting pretty desperate scrap ot batch and leave. As a great need to exercise for me probably not quite a waste of learning time, but it's frustrating.

  • Problem reading data via the Bluetooth Serial Port

    My request is meant to connect with a PC via Bluetooth.

    The PC runs a simple server that reads a string from the BlackBerry UTF and writes a UTF string in response.

    DataInputStream istream = connection.openDataInputStream();DataOutputStream ostream = connection.openDataOutputStream();
    
    System.out.print(istream.readUTF());
    
    ostream.writeUTF("Hello client");ostream.flush();
    
    ostream.close();istream.close();
    

    The sound written BlackBerry pin and reads the answer.

    DataInputStream istream = connection.openDataInputStream();        DataOutputStream ostream = connection.openDataOutputStream();ostream.writeUTF(Integer.toString(DeviceInfo.getDeviceId(), 16));ostream.flush();
    
    _rtf.insert(istream.readUTF());
    
    ostream.close();istream.close();
    

    The server reads and prints the PIN successfully, but the client raise EOFException at readUTF().

    What could be wrong?

    Solved. The server side must not empty its output stream.

  • read and receive data from the server

    Hi all

    I want to develop an application that extract data related to the content of the server, how to do? I read somewhere stating this task requires sdk server push? is it possible do not use push sdk server and the server reading so that I don't have install anyting from the server.

    Your Web service code decides how much data you send or receive from the customer.

    For example, you can have a Web service method, which returns records to a particular date, then you must create a web service method that accepts a date to a string as a parameter and a request for service records of server request, write resultset in encoding (like xml, json, etc) and return this string as a response to the client client will read the data as a byte array, then converts the byte array to the string and according to the encoding defined by service will analyze data of interest.

  • Get to Eloqua 9 data via the API?

    Can anyone shed light on what is available via the Eloqua9 API to get the Eloqua data and also have a system (such as SQL2012) external data in Eloqua push? We are trying to implement the data cleanup efforts in our new tool of Data Quality Services and we would like to integrate with Eloqua. Can you give us some insight and detail on what we can and cannot do?

    Dennis,

    It depends on your business case here and the volume of data.

    Eloqua offers various options of the Soap API & REST.

    Also low volume & bulk options as well.

    For E9, you can start going through the documentation of the Soap API at the following link: -.

    https://www.eloquatrainingcenter.com/Portal/documentation/API/default.htm

    For authentication and exploitation of low volume of use of the WSDL for the Service: https://secure.eloqua.com/API/1.2/Service.svc?wsdl

    More data volume use the WSDL Service of data: https://secure.eloqua.com/API/1.2/DataTransferService.svc?wsdl

    An air of challenge, you can accomplish connecting SQL2012 to Eloqua defining HTTP endpoints and using components of script for mappings of field and transfer data using SSIS.

    For a more robust solution I would develop a .net stand alone application, and you can call it of SSIS in order automation and business intelligence.

    Good luck

  • Move VM between data on the same vCenter centers

    Hey all the...

    With a virtual machine off, I'm migrating a VM between data centers in the same vCenter. There is no shared storage, different networks to the destination host. The user interface works (caveat about the missing shows destination network), yet move-vm does not work between data centers.

    By train: move-vm - vm test-20150309 - destination esx1 datastore - datastore1, I get the error:

    The manual States -Destination can be file, host, cluster etc... As the hosts AND records are bound by data centers, I guess it must know the new host & the new folder. I tried to use - destination twice, and I've tried - destination host, folder.

    Move-VM: cannot bind parameter because the 'Destination' is specified more than once. To provide several parameter values that can accept multiple values, use the table syntax. For example, '-parameter value1, value2, value3 ".

    Move-VM: missing an argument for the parameter "Destination." Specify a parameter of type 'VMware.VimAutomation.ViCore.Types.V1.Inventory.VIContainer' and try again.

    I used PowerCLI 5.8 and tried on 5.0 and 4.0 vCenter.

    PCoIP does not work via the Security server. If you want to use PCoIP over the WAN, you need to connect in a different way, like VPN (SSL). If RDP is also enabled on your pool that view fall back using RDP.

  • Difference between two dates in the server behaviors

    Hello all,.

    I am trying to create a Recordset by using server behaviors and that I'm not an expert in php, I'm completely lost...

    The problem is this: I want to find in a table of all the records where the difference between today's date and date of creation (stored in this table, although course) is superior to, say 30 days. How can I specify the variable field?

    Thank you very much in advance for your help!

    You must use a sql like query below:

    SELECT * FROM table WHERE creationDate< date_sub(now(),="" interval="" 30="">

    'table' is the name of the table that you want to select the information of and 'creationDate' being the column 'date' in the database

  • Data on the server failure recovery

    Hi all

    The rule of thumb: each 1 GB JVM can store 350 MB of data of the real object, assumes that we have 8 GB of data on the consistency, according to the above rule:

    8192/350 = ~ 24 JMVs required = > 24 * 1.2 = 29 ~ GB

    Then we have at least 2 servers of 16G RAM.

    We plan to have 4 virtual machines Java as cache servers on each of the two servers 16 GB as it advocates cannot have more than 4 GB of heap for each node in the cluster.
    I wonder if one of the servers fails, nodes in 4 cluster residing on it go down. If primary and backup of certain data are distributed both within these 4 cluster nodes that descend, then the data is lost even the other server has sufficient capacity for full redundancy.

    Is this correct? If so, how to solve? Is smart enough to put main and in the various boxes, not just different node each time as possible consistency?

    Hi Henry,.

    Not consistency inherently tries to minimize the risk of data loss and automatically checks the backup copy of the data to be kept on a different machine when possible. There is no more adjustment required for it. The StatusHA is the status published by JMX metric of coherence and more details can be found here:

    http://docs.Oracle.com/CD/E18686_01/CoH.37/e18682/appendix_mbean.htm

    I hope this helps!

    See you soon,.

    I have a flex application that allows users to download on our Web site.  When the user downloads their files, I need to make a call to the server to see if their allotted disk space as outdated summer or not (I am currently using an HTTPService that meets return true or false).  Everything is great except when a large amount of files are downloaded at the same time to work.  I am sure that the error is caused by the url being truncated query string because it is too long.  Currently, I am submitting my variables like this:
