Questions about the implementation of clusters of storage and DTS on active cluster

I have a few questions about the implementation of clusters of data store and SRS storage in VSphere 5.1.

We have a data center with about 15 HP blades and a few servers non-lame.  The hosts are all either VSphere 5.0 or 5.1.  Our back-end storage is an EMC VNX 5700 with about 20 stores of data.  All the VMWare is managed by VCenter 5.1 running on a dedicated physical machine.

Currently, each data store is used individually; No piles of data store are put in place.  When a new virtual machine is created, the administrator usually chooses the data with the most space store.  Periodically, we will go back and manually storage vMotion machines to balance the load.

Recently, we have expanded the VNX storage, so we now have LUNS in different pools, with different levels of performance.

What I would do is set up for the data store clusters, so that us when a virtual machine is created, the administrator must not know what data store is in which pool.  Also take advantage of the DRS storage so that the burden of storage will be "refine" himself a little.

I know the setting up of a cluster of storage in a 'clean' environment is quite simple, but my concern is creation/conversion data warehouses existing in active production in the cluster, while they are used.

If I access the screen "data warehouses and store data from clusters ', right-click on the data center and create a cluster, and then move the various data stores in the new cluster, will there be an interruption in the production running systems?

I also wonder about activation of storage i/o control.  It is not currently enabled on data warehouses.  I know it's useful for the StorageDRS, but will be allowing any negative impact on the system?  If I turn on the warehouses of data, is there anything else I should do or set in addition to all that allows him?

Finally, we are in the process of Site Recovery Manager configuration.  SRS has an impact on the configuration of the data clusters and DTS store?

Thanks in advance for your comments.

Hello

Clusters of data and using DTS store doesn't impact RS even if you create a cluster of data store for storage of replicated data and another for everyone else, this way you machines virtual you want to replicate are not moved on warehouses of data that are not replicated , but will still have the ability to move if there is a conflict.

Gregg

With all due respect but SRM and DTS don't go together. SRM does not at all support the use of DTS. So if you are configuring SRM forget DTS for now.

Reason for this is that SRM knows no DTS and VMs can be in flight when a failover should occur, and bad things can happen. Also, the protection breaks when a virtual computer is moved between data warehouses in a cluster data store.

In short: don't go there.

  • Question about the database to use with ESX and Labmanager

    Hello

    Finally my company is buying a permit for Labmanager and ESX server using Labmanager to our tests.

    We had a question about the database that we use for the actual installation.

    Could we use MY - SQL? Or that we have the olbigation to install a SQL or Oracle DB for the whole system to work?

    We prefer to use MY_SQL because it is open-source and will cost less to use for us.

    Thanks in advance for the answer and please excuse my bad English, I'm french spoke first.

    Lab Manager installs SQL Express as part of the installation and use. If you install also Virtual Center as part of your deployment of Lab Manager (do not use an existing VC server), you can use the database SQL Express is included for small installations of ESX, but MY SQL is not an option. You can search the databases supported in the installation guide for what version you deploy.

  • Two questions about the ACS 5.1: password aging and allowing multiple disabled accounts

    Hello

    I test in ACS 5.1 password aging, and I discovered that you can have only one global setting for the password for all the accounts internal life. Is it possible to exclude some internal accounts of this global password aging policy? I would like to have number of accounts, passwords should not be aged at all...

    Second question: when I was testing password aging, I set myself to life of password in 4 days with warning after 2 days. All accounts in my test of the ACS configuration are now disabled, because 4 days has passed when I changed it. Is there a possibility to allow multiple accouns at once, or do I have to activate 500 internal accounts manually, one by one?

    Thanks in advance

    WM

    I'm not aware of any way to score internal as users with passwords as enver expire. This is done for admins ensure there is always an admin who can access the system

    In order to change the multiple/all documents for internal users, the following approach can be taken:

    1. Go to the list of internal users and press "Export" then 'Start export' and 'Save file' export user records to a csv file
    2. Edit the file. In the title 'active' column replace 'FALSE' to 'TRUE' for all records. Save the updated file
    3. To the page that lists internal users, tap "File Options", select "Update", and then click next to access the section "Import a file" Wizard. Select the file saved in step 2) and tap on finish

    Afetr imort is completed, all records of internal user should now display "Enabled".

  • Question about the migration of mass of files and permissions

    Hello

    I'm moving 2TBs of files from one external hard drive to another, but every time that I try to do a file mass transfer from one day to the next it eventually fail due to permissions for some files. I looked at the files on that he objected and I read and write permissions on them, as you would expect.

    What can I do to fix this?

    Try to run repair permissions and ACLs on your record. A repair permissions with disk utility does not have anything in your folder. Boot from your recovery partition now command-keys R in the menu utilities launch Terminal. In the Terminal, type: resetpassword , then press return.  (Note: you won't be reset password)

    Click the icon for the hard drive of your Mac at the top. In the drop down menu below, select your home folder. At the bottom of the window restore Home Directory Permissions and ACLs. Then, click on the Reset button. When the prompt returns to the command line, you can leave out Terminal.

  • Question about the implementation of VLAN automatic voice with Polycom phones on a SF 300 - 24 p

    Someone at - it Setup successfully a SF 300 - 24 p to automatically assign a VLAN voice for traffic from an IP of Polycom phone? We have activated with LLDP-MED policy assigned to the port, as well as the interface configured as a trunk with the PVID defined on the VLAN data and Auto VLAN enabled.

    Hello

    Thank you for using the Cisco support community. My name is Nico Muselle and I work for Cisco Small Business Support Center.

    In response to your question, the only additional thing required on your switch is the choice of one of the below configurations:

    1. Affect the phone VLAN statically to ports connection of phones.

      or

    2. Turn them on Vlan voice (and change CoS affecting 5), and add telephony YES Polycom phones (the first 3 bytes of the MAC). You may need to add a few different Yes. This way the switch detects the phone YES and add the switchport to the Vlan voice.

    LLDP-MED network strategy as you have defined it, on the other hand, will be used to assign the VLAN on the phone automatically if you do not have to configure it manually on all phones.

    In short, you can choose one of the methods above, in combination with the LLDP-MED policy so everythings should work just fine. If it is not, please let me know.

    Kind regards

    Currently, I'm doing some R & D on implementing web analytics in flex. As I understand it, implementation of Sitecatalyst AppMeasurement requires the FLEX SDK 4.0 or higher. Please let me know if Site catalyst can be implemented for flex SDK 3.5 also?

    Thank you

    Joy.

    (1) Yes, you are right.

    (2) you can use the SiteCatalyst extension with 3.5 SDK projects, but you might get errors in the IDE / generated code (we certify the extension to 3.5), although this can be corrected in a future version of the extension.

  • A question about the implementation of a "Comments" link

    All-

    My goal is to put a link "Send feedback" at the bottom of each HTML page generated by HR, to solicit comments from user on the content. I found very little on this subject. This page, the blog "I'd rather written" in 2007, recommends adding a script as follows:

    document.write ("< a href =" mailto:[email protected]? subject = request % 20Name % 20 ("+ document.title +") % 20%20File:%20"+location.href+" "> feedback < /a >" ");

    It looked promising. (Mais il garde de me donner un Expecting») ' error when I use the button 'Search' in the master page. (The scripts link does not appear in the published page footer). However, in the script, the parans are balanced: two left, then right two.

  • Question about the configuration of virtual computer file and the working VM location

    I noticed one of my virtual machines had two data warehouses listed under "Items" in the vSphere Client.

    After some research autour, I found the virtual machine files are in the correct data store, but the 'VM-configuration file' and 'Place of work VM' are in another data store.

    Can I combine all in the same database?   I'd rather have the config and the workplace on ma who has a lot of main storage.  For some reason, the configuration file and the location of work were created on a local storage on my host.

    Any suggestions?

    Thank you

    David Moore

    You can use Storage vMotion to migrate only the virtual machine configuration file to the desired location, just start the wizard of vMotion and storage step 'Select the data store', click Advanced, and you will see the option to select a new destination for the configuration file data store.

  • Re: A few questions about the Satellite X 200-23 G and X 200-251

    There everyone,

    1. is it possible to use these hard disks of 2 x 250 GB in RAID MODE 0 and 1?
    2 - is the laptop DDR2 800 MHz, fragmented into several modules and is also able to run this speed? Standard is 667 MHz FAS so I know and maybe maximum.
    3. is it possible to enable or disable Grafik cards?
    4. do you know if this notebook chipset supports the Quad core CPU?
    5. power outlet must be micro-479 with coupling balls, is that correct?

    Thanks for answesrs really knowing. :)

    Hi mate,

    I have almost the same machine, so I guess I can enlight you with my experience with this type of machine:

    1. No, unfortunately not, the second disc acts as a second HDD and nothing more. You can do software RAID which approximates longer than the share of your intention, but it s not the same as hardware RAID.
    2. no and Yes. No way to won´t CPU works with a higher frontsidebus but yes the modules work in the machine. I guess that the modules will be be underclockes at 667 Mhz to work with the designated CPU frontsidebus.
    3. If you have a SLI machine, you´re able to disable the second card.
    4 No, only the Celeron and the Core2Duo.
    5. Yes, the plug has 479 pin butwhat do you mean with ball coupling?

    Welcome them

    In addition, this machine is not a desktop computer... ;)

  • Satellite P10: Question about the limits of upgrade of RAM and HARD drive

    What are the limits to upgrade my laptop Satellite P10? Currently, I use 1 GB of RAM (2 x 512) and I still have the original 60 GB 4200 RPM HARD drive. I'm mainly interested in upgrading my hard drive to at least get a 7200 RPM 100 GB disc. Better would be one of the ones 24 hours server as Hitachi HTE721010G9AT00, I have just turned off my computer. Which one to take and are there limits (BIOS) (keeping in mind that there will be 200 and even the 250 GB drives next year)?

    RAM: should I put two 200pin SO-DIMM 333 or 533 or should not change at all as it works very well and stabil now?

    Hello

    In my eyes you should follow the guidance of Toshiba line and must use the memory modules that are recommended in the user guide. But if you can also try to test with 400 Mhz or 533 Mhz. I think that each dealer notebook or memory could do that.

    I think the BIOS might be able to handle the hard drive with capacity of 30 GB / 40 GB / 60 GB / 80 GB, Bus Master IDE with ultra DMA 100 synchronous
    In my opinion the BIOS does not recognize the larger HARD drive.

  • Question about the Manager of messages in queue and dynamically load/close Subvi

    Hi, my dear LV users

    I learn how to use the machine in queue Sate Architecture. I created a simple project, including a "main.vi" to dynamically load a sub vi 'sub_Vi2.vi' in the case of "initialize". The sub vi simply open a configuration file and load affecting some control and write these values in the configuration file. If the configuration file is not created, the sub vi creates until the user closes the Subvi.

    In the case of "Get out" of my "main.vi", I send 'true' to the Subvi stop button to stop running it. But the sub vi did not write these values back to the configuration file, or created a new when I delete the configuration file.

    There is another vi I made 'main1.vi', which loads dynamically and close the Subvi. And it works as well as I expected: create the file and write data!

    Can someone help me understand the code? I've also attached the front of diagrams and source code. It's in 2012 LV.

    Best regards

  • Question about the upgrade to ESXi 4.1 and USB keys

    Right now I'm under ESXi 4.1 from a USB key (ie. a very small USB key).

    If I want to "start over" and use a newer USB for ESXi 5 but keep my intact, is guest operating systems - this possible?  (For example, if I install ESXi on a Virgin USB 5.0, will I be able to import my existing operating system vmx ESXi 4.1 images, etc.?)

    In addition, what's the downside of ESXi 5 running from a USB?  I spin this in a laboratory at the House and have read that ESXi basically load into memory if you really start player ESXi itself is useless and a USB key is perfectly fine.  Is this true?

    If you do not want re - configure ESXi 5.0, you can proceed as follows:

    1. Use free software, called "USB Image Tool 1.57" make a picture of your USB 4.1 - software available here http://www.alexpage.de/usb-image-tool/ .  This way you can restore it to any USB in the future.
    2. After making a backup of your USB 4.1 image, upgrade installation 4.1 to 5.0.
    3. Make a backup of your configuration of ESXi using the CLI vMA tool / vSphere in Windows with the following command: vicfg-cfgbackup-next - server
    4. The new installation of ESXi 5.0 on new USB
    5. VMA or vSphere CLI tool use in Windows with the following command to restore the backup from step 3 config: vicfg-cfgbackup-load - server
    6. You should now have ESXi 5.0 works on a new USB without any necessary configuration

    Alternatively, you can restore the image USB created in step 1 on your old USB in order to have a 4.1 installation handy...

    I recommend that make you a picture of your USB 5.0 USB as well just in case in the future USB fails.

  • A few Questions about the export of Animations Formats in and interactive PDF

    Hi people

    According to my previous ramblings, I just go CS5.5 and am very interested in the animation and the side of interactive documents of things.

    I created a document as a test that has a video (mp4) and a slideshow (using the buttons to the previous step and the next step of stacked images).

    I can export it as a swf file, all perfectly, but the first few people I sent there do not have flash player.  I thought that most of the people would be able to open it but apparently not.  Is there a better format for export?

    I tried to export as an interactive pdf, but my slide show button does not work then.  I don't quite see the element of interaction of one interactive pdf other than being able to put in a video (which I have not yet tried).  Im sure someone can enlighten me!

    Any help?  Are swf is intended primarily for Web sites where people can see it this way rather than be sent by electronic mail?

    See you soon

    Animations and slideshow features are available only in a SWF file, which, as you have discovered, requires Flash.

    Workaround: select only the slideshow and the buttons that are associated and export to SWF format using the option on the export dialog box. Then replace the SWF file in InDesign. Use the media panel to create an image of the poster. Can export to PDF.
