question General vSGA and vDGA

Hello

Need to clear somethings

If I have a server with 1 x grid K2 card and to use graphics hardware acceleration that I need to either install the driver ESXi Nvidia vSGA or vDGA right?

If I choose to install the driver nvidia for vDGA I can only configure 2 vms for this dedicated right GUs?

If I choose to install the driver nvidia for vSGA I set up as mush as the memory on the NIC and host memory are able to right? (half mem GPU, mem half host)

What is the main difference between K1 and K2 of the grill rack, is just that the K2 2 GPU?

No matter what expirience with the help of CAD applications on vSGA, im thinking performance etc... problems a user of CAD often must be vDGA (I know it depends on the application, but what's your expirience)?

> If I have a server with 1 x grid K2 card and I have to use graphics hardware acceleration either to install ESXi Nvidia driver for vSGA or vDGA right?

VSGA to install a VIB (pilot) from Nvidia, for vDGA that you don't need to install any driver on the ESX, but in the virtual machine.


> If I choose to install the driver nvidia for vDGA I can only configure 2 vms for this dedicated right GUs?

Correct, but you could also have a configured with vDGA and one with the vSGA


> If I choose to install the driver nvidia for vSGA I can configure as mush as the memory on the NIC and host memory are able to right? (half mem GPU, mem half host)

You can assign max 512 MB to each virtual machine, half will come from the GPU, the other half of the memory of guests as overhead.


> What is the main difference between K1 and K2 of the grill rack, is that only the K2 has 2 GPU?

K2 have 2 GPU:s and 8 GB of memory, K1 4 GPU:s and 16 GB of memory. The GPU:s are very different, but, the K2 have 2 Quadro K5000 and K1 have 4 Quadro K600.

> Any expirience with the help of CAD applications on vSGA, im thinking performance etc... problems a user of CAD often must vDGA (I know it depends on the application, but what's your expirience)?

I have some experience and to be honest its very difficult to say at the outset that the technology that will be more suitable. I recommend to install a few test machines and let real users to evaluate.

For one of my clients, they found the solution not to appropriate to their main designers but are several other usecases, teleworkers, construction sites, scenarios of training partner, access, etc. that makes the very successful solution.

  • GRID K2 vSGA and vDGA Stats

    Hi guys,.

    I have set up on my card GRID K2 vSGA and vDGA.

    I have a desktop dedicated with 1 GPU attached and with dxdiag appears Nvidia GRID K2.

    I have several offices shared using vSGA.

    Both work as expected.

    However when I go to the command line and run the command of nvidia-smi it shows only 1 on the GPU. Now I know what GPU covers desktop vSGA because if I run an application in one of these workstations GPU-Util increases. So why I don't see the use of the GPU vDGA / not even arises? Is this a normal behavior? If so, how can I see the performance of the dedicated GPU?

    Thank you very much

    This is normal/expected since the ESX do not see the GPU that you went through to the virtual machine with vDGA.

    To vDGA, you will need to get inside the virtual machine statistics.

  • vsga and vdga change

    Is it possible to change the type of jobs of work virtual view of 3D graphics acceleration?

    I mean if I have a VM configured for VSGA and only for a period of time they need a VDGA and at the end of the graphic intensive work they need to return to VSGA is possible?

    Yes but it takes some downtime and manual configuration of the parameters of the virtual machine.

    (Unless you do a few scripts around it and automate it somehow.)

    Hello

    Is it possible to have different pool created on the same host and have some VM (pools) that use VSGA and other virtual machines (pool) that are using VDGA on the same host?

    Yes it works very well! (Assuming you have at least 2 GPU:s or Board with more then a GPU as a K1 or K2)

    It's what warranties are for. If you bought the phone from Apple or an Apple authorized reseller, iPhone, you have 14 days to return it for a refund. After that the Bank should replace the phone. If you did not buy from Apple or a shop authorized, you must respect the terms of this store. However, Apple will always replace the phone, if you contact them directly.

    Hello

    I doubt that this is possible because Bluray discs are mostly protected against copying.
    But if you have the Bluray m2ts file on your HARD drive, then you could try the tool called convertXtodvd. But I don't see that the reasons for this
    I mean that you will lose the quality of film converting the blueray to dvd.

  • Trying to follow a question re ITunes and shuffle.  Links on the email no longer work.  How can I do this?

    Why Apple Support community-is such a maze.  Surprisingly, after much effort, I have a question was asked and answered to (helpful but not completely).  In trying to follow up, I have found no direct link in my email, no way to find my name in the communities of support and no way to push my question to the next level.

    I know now how to disable "shuffle" in my ITunes on my IPhone.  Is not very intuitive, as some helpful person has said.  Also, the highlight on the button 'shuffle' is unnecessarily pale.  So now, because since then, shuffle returned requiring manual turn off again, is there some default to shuffle?  I've experimented with compensation the ITunes program and with the phone turned off/on.  Neither returned me shuffle.

  • I have a question comparing Dreamweaver and Muse.  Can I create a website with Muse, then learn Dreamweaver, and edit the site Web of Muse?  Or would I need to start over with a new Web site based on Dreamweaver?

    I have a question comparing Dreamweaver and Muse.  Can I create a website with Muse, then learn Dreamweaver, and edit the site Web of Muse?  Or would I need to start over with a new Web site based on Dreamweaver?

    I went the same route. I started to want to learn web design and the Muse is an excellent tool. The code it generates, however, not to use it in Dreamweaver. This could be done, I think this isn't worth it, even for a real Geek. Once you get to Muse you will find there are things missing, stuff, you want to do, but are just tough in Muse or you can buy a widget. It is possible in DW and you get which through subscription, so it makes sense. Me what I know now, I'll go directly to DW to learn, except if you want results right now. If you don't want something to cause I stay with Muse and maybe learn to animate CC to add some pizazz to the site. If you only want a simple layout and a couple supporting stick with Muse pages if you want a larger site use DW. Good luck and check out this page to Muse on Google Plus Adobe Muse for beginners - community - Google +...

  • Big client - vCenter 5.5 response time of the customer Web U1c / questions of Performance and Navigation

    So we're all aware of the issues with vCenter 5.5U1 WebClient and how we are forced to use it to make use of all the features of the v10, vDS 5.5 vHardware (config switch changes the synchronization problems if an emergency change is done on c# client vDS) VSAN only available via the web client, flash, sluggish to questions do not respond the questions and the list goes with the presentation of the menus and hard to navigate, issues SSO (always after 5.5 upgrades)

    So @ VMware vCenter Architecture Team is going to make an effort to hear and give due to the much needed performance improvements and improvements to the user interface before adding more features and SSO type services which majority of clients don't use not and not force it's customers continue to loose faith its vCenter product?

    Looking for answers with options to remove vCenter 5.5 U1c installation as well as a promise to answer to these in vCenter 6.0 version!

    Here is your answer. First of all, to use Chrome as your browser, then you need to go with at least 4vCPU * 32 GB of RAM & adjust the segment size of java for SSO, Tomcat, (TC) Management Server, inventory server and profile based storage to "refine" vCenter device with DB Oracle embedded or external memory. I did, and performance gains went 10 X. This includes the vSAN enabled running clusters. My recommendation that works very well based on design documents:

    vCenter Server inventory

    VMware VirtualCenter Management Webservices (tc Server)

    The inventory service

    (Sps) profile-based storage service

    Large (more than 400 guests or 4000 VMS) stock

    4 GB

    12 GB
