VMware clusters and extending on L2

Server virtualization and coud computing are the driving forces behind the need to cover the area L2 network. It was TRILL comes into play.  You get horizontal mounted in a flat network, with several paths of transmission of L2 powered by TRILL.

The question I have is just how far through the data center the field L2 really should extend? To say that this is a vmware environment. The latest version of vSphere allows up to 32 servers per cluster.   In addition, it is only within this 32-host cluster a vmotion or DRS or FT action can take place. Theoretically, you can configure the cluster vmware for the duration of the entire, end-to-end farm. But in reality, the vmware configuration clusters? I think the hosts in a cluster are largely set up in adjacent cabinets, not through the entire data center. So, do you REALLY need extend the field of L2 on the whole farm data center?

When a cluster of 32 hosts is built, the servers are normally adjacent to each other and connected to the same switch infrastructure, correct? Imagine I have 50 racks of servers, a cluster is NOT normally the 1 and some rack in rack 10 servers... and other rack 48... fix?

Depends on what you mean with grid 1, 10 and 48 - is it for servers show that these media are located physically outside or just that they are separate groups?

In general, it will be good to have to cluster across multiple grids - from the point of view of VMware HA which is another 'cluster active the feature' in general, as well as the Drs HA will be able to restart virtual machines on other so physical host to one or more hosts dies.

This also means that it might be wise to separate the members of the cluster of several grids / chassis blade or other who could do together. A view of high availability, it may be good to have a few physical hosts on the same grid (or others who might share common power or similar).

    Should I just consider that last?

    Thank you

    It has to do with availability solutions.

    You can protect aid comments clustering or using the solution services that protect the virtual machine (such as VMware HA and VMware FT).

  • Requirements VMware HA and DRS.

    On vmware site I was just brushing my knowledge on VMware HA and DRS and found a conflict. Someone can it confirm please.

    One of the requirements for VMware vmotion and DRS turns "the virtual machine configuration file must not reside on a VMFS located on the shared data store. . . "(Ref: http://www.vmware.com/support/vc13/doc/c2vmotionreqs12.html) "

    But VMware HA says one of the requirements as "cluster-enabled VMware HA, all virtual machines and their configuration files to .

    reside on the shared storage (Fibre Channel SAN, iSCSI SAN, or NAS iSCSI SAN), because you have to

    ' be able to power on the virtual machine on any host in the cluster " (Ref: http://www.vmware.com/pdf/vmware_ha_wp.pdf ( )

    What does that mean? Or the constraint of VMware vmotion is wrong? I'm just confused!

    The first link is-old vMotion applies to Virtual Center 1.3 and ESX2.

    "The virtual machine configuration file should not reside on a VMFS located on the shared data store '... This applies to 2 ESX hosts. At the time, the virtual machine configuration (.vmx) file was located locally on the ESX host, run the virtual machine in/home/default vmware...  This file have been moved to the local directory on the target host during vMotion...

    This was changed to ESX3, who, with Virtual Center 2, introduced also HA...

    For HA to work all the VM files must reside on the shared storage. This makes all slender VM files available to other hosts of clusters at all times. (difficult to extract different files from a host of dead).

  • ESX3.5U4/VC2.5 - move vmdk to adequate data store and extend the drive on the virtual machine

    ESX3.5U4/VC2.5 - move vmdk to adequate data store and extend the drive on the virtual machine

    Objective: move vmdk to store data with adequate storage and then increase storage D: 20G to 100G

    Converter is not available on this architecture. Can I migrate cold vm to the different data store, no prob.

    Question: Without use of the converter, method 3 can be used without a secondary vm? In other words, just by using target vm offline, online, offline? Or is it a problem of signing/OS disk on the Windows Virtual PC?

    I need to move vmdk in different LUN and extend drive vm windows on D: (non-OS drive). Is this possible via the single procedure? Options?

    To use method 3 to http://communities.vmware.com/thread/81121 requires available vm 'secondary', I did not.

    Method 3? Using of vmkfstools and another VM of Windows to extend a drive

    o stop the VM to resize

    o log in the console ESX Server via Putty

    o Type? vmkfstools? X & lt; new size of drive & gt; vmfs/volumes / & lt; storage volume name & gt;. / & lt; virtual server name & gt;. / & lt; the virtual disk name & gt;? That is to say. /vmfs/volumes/Storage1/my_vm.VMDK new disk size can be specified in kilo, mega, or gigabytes and will be the total size of the new disk. So if you want to increase a virtual disk of 20 GB of 24GO you would put 24000 m or 24g

    o the second virtual machine to help stop

    o change the second virtual machine settings and add the first virtual machine hard drive

    o power on the second VM and load the disk management snap-in and verify that the first virtual machine disk has unallocated on it space

    o select Start, run and enter diskpart.exe

    o the command? the list of volume? This will show you all the volumes.

    o select your volume based on the results of the list volume command, IE. ? Select volume 1?

    o type the command? extend? to extend the volume

    o check again the disk management snap-in and the volume is expected to be expanded with a greater ability

    o stop the second VM and remove (do not remove) the record of it

    o turn your first VM and the new space should be there and ready to use.

    Also, I'm already aware of Dell extpar:

    for VI3, vmoiton of storage is made by RCLI plugin or a 3rd party

    I prefer the plugin

    http://www.virtualizationadmin.com/articles-tutorials/VMware-ESX-articles/VMotion-DRS-high-availability/storage-VMotion-SVMotion-VI-plugin.html

    In addition, if the option to increase the size of the disk in the VIC is grayed out, it sounds like a permissions issue.  Finally, you can not extend the disc using the VIC, if the customer in question has a snapshot.

  • sleep and extended problem solved!

    Hi all.
    Finally I solved my problem (see "sleep and extended in windows XP" for more details).
    I uninstalled everything on HP printer because Windows XP plug-and-play service does not load the Power Manager settings if it is not the printer.

    Now I understand why the HP software does not work properly, you know?

    See you soon.

    Gianluca

    It seems that the HP software has adopted some features of the operating system. Normally, it is very good for the manufacturer to give the features more functions.

    But if there is a third software such as Power Saver from Toshiba could occure problems because the energy saver adopts XP power settings and it administer very dominate. If the HP printing software was not able to adopt the settings of MS!

  • Registration for the Standard warranty and extended

    I have registered my system to the Standard warranty and also fact of registration for extended warranty Service (2 years) and _got message for registaration successful for both, standard warranty and extended warranty_. But on the verification of the details of my system to it always says my system is NOT REGISTERED and the guarantee here it shows only 365 days and not 3 years!

    Can someone pls help and inform me of the email address of contact of the Toshiba research customer service records and warranty extensions?

    * After how many days they are updating the registration information on ? *.

    Maybe something went wrong during registration or the system not updated status. As Jeffrey has already suggested, eventually the data was not updated and you have to wait one, two day (s).
    If we can't change the status of the guarantee, contact the service provider to authorize to clarify this issue!

  • Table of clusters and the cluster is a bar counter, how can I change the color individually?

    Table of clusters and the cluster is a bar counter, how do I change the color of the bar individual meter for each element of the array?  I just realized that you cannot change the properties of an element of the array without changing everything.  For scale, I had to make digital for each graduation of the scale indicators so that each measure meter in the table in the cluster has individual scales.  I also had to do some calculations for each barmeter to display the correct proportions of 0 to 100% on the scale.  Now, I'm stumped on the color of the bar counter.  Basically, if the value exceeds a set value, the meter bar should turn red.  It must be in a table to be infinitely scalable.

    Thank you

    And yet anothr approach...

    Right click on the bar of > Options to fill > maximum fill.

    The fill color of the same color as the background color, then make the background color transparent.

    Drop a box of color BEHIND the bar and the size correctly.

    He has this strange background 3D with flat bar, but what the Hey, his relatives. If its important a custom color box.

  • Question and Wireless N router and Extender G

    Hi all

    I would like to install internet ADSL2 + wireless in a hotel. I was thinking of doing this:

    Buying a router Wireless N ADSL2 + and extending it by buying a Wireless Extender G. Now when you visit the Extender G page it indicates the routers supported etc, only G routers are listed. Routers Wireless N do not work?

    If someone has a better idea to solve my problem please, say so.

    Internet to the 1st floor and must be extended to 4 other floors. The 1st floor to ceiling 2nd floor should not be a problem and the 2nd to 3rd and from 3rd to 4th should also not be a problem.

    Just buy a router Wireless G with Speedbooster and 3-4 Wireless G expanders?

    Thank you!

    Yes the Wireless G Extender works with the wireless G router. That you are considering buying an N series router, then you can go for an Access Point WAP200, you can set this access point in Repeater mode, and it will solve your purpose.

    Alta application means - you change your application to alta and using only Alta Skin default skin

    While Extending means that you use your own skin (custom CSS file) that extends alta means you use alta, but you changed it for some components

    You can do something like this.

    But be aware that it will not report VMHost, Clusters and data centers that do not have any virtual computer in them.

    {foreach ($dc in Get-Data Center)

    foreach ($cluster Get-cluster-location $dc) {}

    foreach ($esx in Get-VMHost-location $cluster) {}

    Get-VM-location $esx |
