Sizing of VMware Infrastructure

If you are going to build a VMware infrastructure, consider yourself the hyperthreading the processor function in order to have several virtual machines per server.

Example:

carrots 2 x 10 = 20 hearts (Physics)

40 carrots (with hyperthreaading)

I guess that 75% will be used for virtual machines and 1 vCPU per VM

1-15 virtual machines for physics

2 30 VMs with hyperthreading

which is the best architecture, based on the physical cores or it is safe to use the feature hyperthreading for VM deployment.

Finally, if I use the physical cores, is it safe I guess 1 physical core = 4 vCPU?

Thank you!

You must not consider hyper-threading, you still share the physical heart.  Here is a good article about the sizing and hyper-threading Gotcha Hyper-Threading with Machine vCPU virtual sizing - Wahl network

It's safe I guess 1 physical core = 4 vCPU?

You should never assume anything in a design unless support can be posted in the event of oversubscription, you must confirm that your workload won't suffer degradation performance if the CPU use increases.  You really need to understand the workload and usage patterns.

  • VMware Infrastructure Client hanging

    Hi guys,.

    IM new to the world of VMware sorry, I have a server ESX 3.5.0 Build 82663 on a Dell Poweredge 2950 Server VMware Infrastructure Client 2.5.0 build 84767 on a Dell Insperon running Windows 7 workstation, the question I have is that the VIC has recently started to hang when I try to shoot to the top of the list of the VM on the ESX Server machines. The only way I found to fix it is to reboot physically the ESX Server and then I can reconnect the VIC and get the list and start all the VM images on it, but sometimes it will freeze just when starting a picture and if I click on the power on option, once again, I get a message indicating that you cannot start a power on operation when it is being , and then I'm back to square one where the VIC is frozen again.

    Is it possible to restart the game VIC in the ESX box without having to restart the ESX Server?

    Thanks in advance

    Werner

    How much memory you have configured for the service console? Perhaps, if this isn't there, set up to 800MB.  In addition, confirmed the same behavior by launching the VIC from another post of work?

  • Fatal error VMware Infrastructure Client

    Hello.

    I use vSphere Client (version 4.1.0 build 258902) and vCenter Server (version 4.0.0 build 208111) with an IBM BladeCenter.  I am trying to download files on a satastore, but just as he begins to transfer I get this error and closes the client:

    VMware Infrastructure Client fatal error: (app-4048) <-this number changes every time, it's never the same

    Exception 0 x 80000003 (debug break point) has occurred.

    A core file is available in "C:\users\Dave\AppData\Roaming\VMware\vpxclient-3784.dmp".  Please

    ask for support and include the content of the core file.

    To collect the data to submit to the VMware support, run 'vm-support.

    We will respond on the basis of your entitlement to support.

    I get this error, regardless of the OS (tried Windows XP and 7), logged-in user or data store used (we have about 8).  Fails also on local storage for the blade so it can not be anything to do with the fiber storage attached.

    Anyone hit this problem before and have a solution?

    Thank you very much

    If you use vCenter 4.0 I advise to use the same version for vSphere client because there has been some problems with the customer for 4.1 when used with mixed versions of ESX

  • Alternative to VMware Infrastructure Web Access?

    I had absolutely horrible experience, try using the VMware Infrastructure Web Access site to manage my VMware Server 2 (2.0.0 - 2.0.2), but I spare you the rant about the problems.  In short, I expect more distributed as alpha software.

    Is there another program of VMware or someone else who will allow me to manage VMware Server and access the console of the virtual machine.  I liked the product for Server 1.x, but unfortunately, they removed support.

    Yes, he must be the customer of ESX3.5.  Specifically Virtual Infrastructure Client 2.5.  I do not know which build ESX3.5 I got the customer, but it was there are a few updates.  So, you might try the extraction of the ESX3.5u1 or u2, if the current version of u5 does not work.

    A major limitation with the VIClient is that it cannot completely handle material type 7 VMs.  (e.g.: Server2.)  You can start the virtual and other computers, but cannot change the settings of the virtual machine.  If the virtual machines are the older type 4 (e.g.: Server1) then you can make full use of the VIClient for everything.  However, the type 4 does not support USB2.  You don't have to have all your virtual machines as type 4.  My server has a mixture of types, but I have to remember which are of type 7 and use the web interface to modify the virtual machine settings.  But apart from that, I use the VIClient to display the console for all virtual machines.

    If you can live with the older hardware type, the VIClient is absolutely the best way to manage the Server2.

    Your ESX3.5i server is not functional in eval mode. It is a free product, but you must obtain and enter a license key. You should have received this once you download the software from vmware.

    I was under the impression that VMIC and ESX3.5i are free tools?

    They are both.

    Is it not the case?

    Yes they are free, but you must enter the free license key that you received from vmware. It has been some time, I do not remember if I have received me by e-mail or on the download page.

    Also, what is the relationship between the server, VirtualCenter and ESX3.5i and VMIC?

    vCenter (VirtualCenter server) is the management server can manage multiple ESX/ESXi hosts at once. It also provides some additional features, such as vmotion, integration with active directory, etc. - it is not free

    ESX3.5I is one of the hypervisor servers based that you run your virtual machines on - it's free, but you need to get your free license key.

    VMIC is the client software that you use to connect to vCenter or ESX/ESXi host to manage your virtual environment, including the ESXi host. -free and can be downloaded for the guests, once installed ESX.

    If someone can point to explanations on this, it will be a great help.

    Yes.

  • using the converter no option for "Type of Destination." I am allowed only 'VMware Infrastructure virtual machine'

    Hi, I am looking to convert my localhost Ubuntu 9.10 for a machine virtual (vmdk) using vCenter Converter Standalone Client 4.0.1.

    I am at the step #2 (specify the Destination) and I expect to converter to allow me to choose a path to store the hard files.  However, 'Destination Type' does not have any selection - only 'VMWare Infrastructure virtual machine' is available.  (also there is input to the server, username, and password fields)

    What I am doing wrong?

    Thank you

    Hello

    using vmware converter 4.01 when virtual do physical power machines Linux the only available destination is ESX (i) server.

    One possible way to solve this handicap can be what makes an image of the Linux system using one of support for the products of the image and then use the vmware converter to set up the image of Linux box as a source and destination that it doesn't have to be a server ESX (i)

    If it comes to an eventual conversion, you can use a trial license with the product of the image (e.g. acronis true image or norton ghost).

    Best wishes / Saludos.

  • VMware infrastructure documentation format

    Hi my implementation team recently made implementation of vmware infrastructure 3 and 4 for me. It is now time for the time of transfer and transition knowledge for my in-house team. so can someone please give me a format or a point on which we can take as a transfer of our implementation team. KT base Administration already has been made.

    Hello

    Most, if not all of these types of documents are under NDA, so we can share them unfortunately.

    The content coverage of the entire infrastructure will include details about the construction, the material provision, sites Web HCL, how hosts are configured, which served to test, etc.. Its a kind things coconut soup. Maybe explain why a choice has been made.

  • Possible to download only the VMware Infrastructure Client?

    I am a student, our University has a vmware server we can connect using what, in my view, is called the "VMware Infrastructure Client" of our school computer lab and I was told that you can also download the same client to connect from our own pc at home. (We use a VPN). I've been looking around this site, and no where do not see just a simple download for only Vmware Infrastructure Client, I think that's what I use to connect to the server, our school has running vmware. I tried a few free vmware download from this site, and they seem to be 600 MB + packages with many, many zipped files, not just a simple client that I'm looking for.

    Can someone tell me if there is a way to download a customer of VMware infrastrue, UPS said, and if that sounds right, then I could use to connect to a server on a network running vmware.

    Basically, I have the IP of our server of schools and a user name and password I use to connect to it, but I need to find and install the vmware client to connect to it.

    Hello and welcome to the forums.

    Use a web browser and open https://schools-vmware-server-ip and you should be able to download the client here.

    Good luck!

  • VMware infrastructure management - time necessary to do the job? Tips and advice needed please.

    guys / girls - some notice on the amount of work required to maintain and develop a VMware Infrastructure setup as follows:

    9 blades (BL 465 & 685) HP connected to an EVA 8000 (double fabric connected)

    Set up 2 separate HA /DRS Clusters running ESX 3.5 Update 3

    130 virtual machines, mainly under windows 2003 (backup VCB full every night)

    How many hours per week would you say, in your experience, should maintain, troubleshoot and develop (stay up to date with patches, etc.), critical infrastructure of this size in an enterprise environment with 2,500 users (IE if something goes wrong then there will be serious questions asked). The job would mean ensuring full availability etc. and a capacity of DR.

    Be as conservative as you like, duties include looking after the equipment, and (with HP support relevant contracts), could understand you short if possible reasoning. The turnover of virtual machines is about 2 per week.

    Hello

    last part of the puzzle is man how many hours per week would you must employ a person to perform the infrastructure once implemented. (ie. verification of backups, torubleshooting of performance issues, the provisioning maybe some new virtual machines per week, now patch levels and take care of the equipment, etc..)

    For this size environment, I would have a virtualization full-time administrator who works closely with your storage, network, server and application teams to solve problems. Almost everything from the beginning will be considered a problem of virtualization. You need a good plan on how to handle this. You will need a team made up of members of other teams to manage all possible problems.

    Again be as conservative as you want. I'll assign the points after this bit.

    I probably aim for at least 2 people for full redundancy. The work does not stop when you're on vacation.

    3-9 guests can be easily managed by a single person, but we're going to do a bit of math...

    150 VMS to start...

    Let's say you need to VMotion all 150 VMs... Say 30 seconds per VM, if 150 * 30 = 1.25 hours = average 2.5 hours of interruption, etc..

    Let's say you need to SVMotion all 150 VMs... 1 GB/s with an average 24 GB per VM so 3 working day in SVMotion tell everything... Closer to 1 week. Its a drive problem.

    Now add both to:

    Debugging problems of enforcement...

    Debugging problems of storage...

    Debugging network problems...

    Guest operating system problems debugging...

    Debugging problems ESX...

    Debugging performance issues...

    And the time to add:

    Reports required by management...

    Duration of training...

    New implementation time VM...

    Nerw material planning...

    DR testing and planning...

    etc etc.

    It is at least 1 person complete if not 2.

  • Local host for VMware Infrastructure Client permissions

    We normally use vcenter 2.5 and ESX 3.5. Our user permissions are set on vcenter, using Active Directory.

    However when vcenter is out of service, we can connect locally to each esx host using the VMware Infrastructure client. Logging as root works very well. However, we have several local nonroot accounts defined on the ESX host.

    How can we give users permission to open a session? We want to be administrators on the graphical interface, but does not give the root password.

    As root, you will need to identify yourself with the VI Client and assign permissions to non-root users to access environment - but caution that you do not have the granularity of permissions, as you do with VC and if these hosts are managed by CR you do not want to make changes to them directly as this may affest DRS and HA-

  • not getting does not clone/update with VMware Infrastructure client option

    Hi we have an esx3.5 with VIM 2.5

    to authorize the server through a host file, that we had to create a virtual machine on the esx server and install VIM 2.5 above, pointing licensing to the ip address of this server. This vm is winXP so everything works fine.

    When we try to connect to the ip address of the winVista esx server, we get a Manager, without options - clone/updates

    Therefore, in order to make any kind of cloning or updates remotely of machines WinVista you must:

    create a VPN connection on the site with the esx server,

    Connect to the ip address of the esx server,

    Open the VMware Infrastructure client,

    opening of session

    Open the console of the computer that has installed VIM 2.5

    and perform a cloning from inside the virtual Windows XP machine

    as you can see it's pretty heavy. is there another way?

    Thank you!

    Because if I understand your message, you don't see the "Clone/Update" option in the menu when you connect thru customer VI ESX Server. Yes, this isn't. ESX does not provide the functionality without VirtualCenter. Then, must use VirtualCenter, address IP/Hostname in the VI Client to accomplished these tasks.
