clusters of vSphere 4: servers with different RAM

We have a vsphere 4 update 1 cluster with 9 servers inside CVS mode. The last 2 servers we added were based Nehalem and asked EVC mode since we couldn't not other models. The new nehalem servers have 36 GB of RAM each, and the other 32 GB of RAM each. We seek to bump the RAM in the nehalems to 96 GB for a little more life before moving on to a new generation of FARM we design.

I noticed DRs takes much longer load (RAM wise) on the nehalem servers (upward in the order of 80-85%) while keeping the 32 GB servers throughout the range of 50-60.

Is it normal or bad idea to have the servers in the cluster that do not match the specifications of others?

Any advice or experience with this?

Points are waiting for your reward!

I think that you have no bad problem with that. Have in mind, only that your Sub 36 GB will serve as hosts of 32 GB will not be able to manage the memory all the costs of the 36 GB ones in case of failure of the HA - HA Yes will be somewhat more difficult to limit the number of VMs you will be able to marketing in all hosts If you have enabled HA and a strong constraint on the virtual machine powered on.

  • SRM with different CPU clusters?

    Hey guys,.

    I can't find info on it so I hope someone can point me in the right direction.

    In SRM, geographically dispersed clusters can have different CPU providers? A group would be entirely AMD and the other an Intel.

    I have no experience with MRS whatsoever, and since the VM will be restarted remoetely I think that it would work. If it was me, I would

    remain consistent even if

    Please consider my response as 'useful' or 'proper' marking

    If I understand your question, you will not have a problem with different types of CPU in your clusters to protected site vs.recovery...  The only downside that I can think of is to old versions of Linux not having only not modules loaded into the kernel of the architecture of the chip.  I've personally done this and still have a single cluster of Intel that retrieves an AMD cluster, all virtual machines of RHEL 5.

  • Licenses that merge with different activation time

    Hello

    I want to merge two different activation time license. I found that there is a solution for this http://kb.vmware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 2006973

    But some question appears in this operation:

    1 time activation may differ by more than 30 days (a license has been purchased and activated in September and the other was purchased and active in June) type of licenses will be the same example - VMware vSphere Standard for 1 CPU with 1 year of support in version 5.5, how support for this looks?

    2. what type of license do need me for server with 2 processors with 8 cores and 192 GB of RAM, this license fits my needs? Is there a single license covering such a feature?

    On the HP site, I found only licnses for 1 CPU http://h30094.www3.hp.com/searchresults.aspx?store_id=11 & search_id = 67 & dept_id = 1328

    3. should I VMware vSphere Standard at least to connect to vCenter VMware?

    THX in advance for any replay :-)

    From vSphere 5.5 all basic and memory restrictions have been removed, and licenses are simply based on the number of processors physical Sockets (see http://kb.vmware.com/kb/2064117).

    What you must ensure is that the license key you want to assign has at least the capacity of the CPU. You can merge the license keys for the same version/edition even with different dates of SnS. However, this will not change SnS and end dates will always be displayed ion the MyVMware portal.

    vCenter Server is optional and licensed separately and is necessary if you want to manage a cluster host, or use additional features (for example, the cloning, live migration,...)

  • ESXi 5.5/Workstation 8, how to make my computer prompted with different CPU

    Hello gurus,

    Let's start which is my goal. I need to create a virtual machine with different hardware (I have no problems with the HARD drive and RAM options). I need the CPU on the system invited to be Intel or SMA.

    My host system is with Intel CPU and Intel part it I don't find any problem. But there the prompt with the SMA is the trickiest part. Does anyone know any thing or any software that can make this possible?

    I also tried to build ESXi 5.5 as a guest on my workstation, but here I can't find how to (if possible at all) the CPU ADM.

    PS Comments OS it is win2k3/8/12

    Thank you!

    Hello Asen,

    You can abstract only that physically you have, so you can't emulate AMD CPUS on Intel CPU hardware.

    For guest with AMD CPU instructions you must use physical server with the desired provider in your case with AMD processor installed server.

    Kind regards

  • Cluster with different host - resource pools hardware?

    Hello

    We have currently three generations of servers at base of AMD in our environment - with different CPU clock speeds.

    Guests are split into three groups and VMs are grouped based on clock speed.

    But frankly, it's a mess to administer.

    We envisage the creation of a single cluster and using pools of resources.

    But CPU resource pools take host speed of the CPU in return?

    - Or they just sure that VMs receive their share of CPU temps on loan-time partial?

    Best regards

    Martin

    Pools of resources sharing works only when there is some conflict of resources.

    -VMs in 'high' will appear on hosts with fast processors? - and get the most MHz?

    The actions are only priority... Then no.

    With a reservation... it depends on how much MHz offers...

    - Or they simply receive a high share of CPU time on a random host?

    By shars Yes...

    But remember the first sentence!

    If you have enough of free resources, all virtual machines are also (for actions).

  • Low CPU with high RAM compromise?

    I was searching online for a confirmation, but have not yet find something, so I wanted to post on these cards. On a large cluster of machines (a few hundred), the load on our resource monitor said that we push % on CPU and RAM 70 %5. We are setting up a new environment and thought about order of servers with a single socket processor and much more RAM.

    Did anyone see issue by doing this? If this is not the case, how is it many people buy machines to dual-core instead of a nucleus?

    You set yourself for a lot of problems goes in this direction. As others have also posted it, you are much, much, much better off getting servers with double plug, multi-core (at least Quad-cores) that reduces to one taken. According to the processor that you look at, it is possible to go to a GHz slightly more low discretion model, depending on what happens to be operational there.

    Personally, for a production environment design, I will not under a pair of Xeon E5520 to each host server.

    With the double Sockets, you will have the best memory options available to you as well. In fact, you are ready to a lower limit on the amount of RAM you can install when you use a single socket these days. Basically you're max is going to be 1/2 of what it would be with two CPU installed. Because the memory is one of your main concerns, you'll be streaked yourself by reducing the CPU when it's your limit of memory.

    I confirmed it (quickly) with a Dell R710 build... With two processors E5520, the limit is 192GO (12 sticks) of RAM... With one, she is reduced to 96GB (6 sticks)...

  • I have a strange problem with my RAM supported by installers. When I check the activity monitor, 3 installers are open and they start around 80 MB memory RAM used for about 7 or 10:08 minutes or so.

    I have a strange problem with my RAM supported by installers. When I check the activity monitor, 3 installers are open and they start around 80 MB memory RAM used for about 7 or 8 concerts after 10 minutes. I have to force them to quit, but I don't know what I am closing or why they open in the first place. Applications downloaded on iTunes?

    In addition, the Console has opened with the same message several times, but I don't know what that means.

    Any help would be appreciated.

    Hello

    The last is a picture of the Terminal window.

    Just because it lists 'Console' does not mean that it has nothing to do with this application.

    You have not said why or what you're trying to install so I can't help with that.

    You can use the activity monitor to leave their.

    After you select an item, use the X in a type of stop sign icon and confirm force quit.

  • Photos with different apple id: s

    Any way to sort photos taken with various apple id: s in photos for mac? I have three different iPhones that has been moved from parents to children. Is there anyway to sort images with different apple id: s? I heard that there is way to sort different (smart folder) with the model of phone, but this is not enough cause phones were used earlier by the parents. And I want to use only a single library of pictures, so the different IDs: s for mac is not the solution. It would be nice to get this functionality.

    You can use smart albums with a combination of constraints: the model of the iPhone and the date rank when the iPhone has been used by a person in particular. If the iPhone has been in use you make in the years 2012 and 2013 creates a smart album that will check for the ipHone and the date range.  Then announces a keyword "Photo by Me" of all the photos in this album. Do the same for the other ranges of iPhones and date and assign the photographer as a key word.

    If you keep marking new imports with a keyword of photographer then you can create smart albums for every photographer.

  • The ipad pro supports multiple monitors with different content on each screen?

    I want to replace my laptop with an ipad pro.  Currently I drive three screens with my laptop, all with different content (VGA, HDMI, laptop screen) with no additional adapters.  The Ipad pro has a video card that will allow me to run multiple monitors (3 including the pro) with different content on each monitor?

    Given that the pro iPad running iOS and iOS do not supports multiple monitors, I would say no. I may be wrong, so feel free to correct me.

  • Satellite Pro A200 - cannot start with new RAM

    I have two of these laptops, both purchased at the same time.
    I upgraded to 320 GB hard drive and tried to move the RAM to 4 GB as the spec States can be made.

    I used the recommended type of RAM, but the computer does not start with two RAM modules inserted. If I remove one of them, the laptop boots! I thought that I update the BIOS but found the only version available on the download web site is the same as I.

    Does anyone have an idea what could be wrong?

    What RAM you bought? I think that the modules are not compatible or your chipset does not support the 4 GB.
    Check it with CPU - Z!

    You could test the RAM with Memtest86 ([www.memtest86.com]).

    I doubt that a BIOS update will solve the problem. A more recent BIOS does not change the decision-making ability and/or supported RAM.
