• What is the advantage to affect multiple virtual machines in a data store?

  Hello

  Quite a question stupid and basic, but I can't answer . What is the advantage of having multiple virtual machines in a store of VMFS data instead of having each VM in another VMFS data store? (eg. 3 VMs in 1 data store or 3 data warehouses and each virtual machine in one of them). I can only think about the ease of management for storage administrator because it creates only a single large LUN.
  
  Thank you

  By allowing multiple virtual machines in a data store, you can run more than 256 virtual machines in a DRS cluster.

  As a host has a limit of 256 scsi identification numbers, which means that it accesses no more than 255 LUNS shared. 1 scsi ID is used for local storage.

  In a DRS cluster as each host must be mapped to the same data warehouses to ensure that virtual machines can be moved on the cluster and run on any of the hosts.

  Now in my life as an architect VMware PSO I saw that a lot of virtual machines that require a single data store. The main reason to isolate a virtual machine on a data store must provide sufficient i/o performance. This can be achieved with other solutions than to isolate a virtual machine on a data store. Having a properly architected storage subsystem is crucial, vSphere can get out of a very large number of the IOPS / s. With technologies such as SIOC and DRS for storage, you can check that the virtual machines receive IO performance according to the needs.

• Use the diskette of esxi for virtual machines

  Hello
  I would like to set up a lab and I have hp g6 server but just with a single 600 GB sas disk
  is it possible to install esxi on it and also use it as a storage device for virtual machines on?
  I know that I can install esxi on a cool drive but if what I've said, it's possible I prefer to use that
  Thank you very much

  It's true.

• What are the limits of size of virtual machine to use the mode of transport NBD in VADP?

  We have some problem to run backup VADP with EMC² Networker 7.6.2 with a virtual machine which, in total, amounts to about 2.3 TB of data.
  The configuration is the following:

  VM (file server) running on Windows 2008 R2

  The backup server (physical) is running Networker 7.6.2 and is also host to proxy for backups VADP.

  VMware vSphere, ESXi 4.1 Update 1

  When we make a snapshot of the file server ESX, no problem.
  When we try a support VADP through Networker, it fails with the following error:

  Creating a snapshot for ' vm-2153'...»
  Task is-1% complete
  Task is 95 percent complete
  Task is 95 percent complete
  Task is 95 percent complete
  Task is 95 percent complete
  74854:nsrvadp_save: VMware following associated error has occurred: cannot create the snapshot "_VADP-backup_" for VM: vm-2153.  Details: "an error has occurred for task"CreateSnapshot_Task".  Details: Operation timed out. ».
  80405:nsrvadp_save: could not create snapshot for VM 'PWVFILE05 '.
  The temporary "V:\backupvmware\PWVFILE05" for VADP directory deleted.

  Other (smaller) customer VADP backups are running thin.

  Someone told me that the business day following a certain limits on the size of the virtual machine.
  He said when he sized VM is equal to 1 TB or more, we should NOT use NBD.

  Anyone explain to me or provide me with evidence?

  Yes, I think it's the best option, visitors don't like the 'limits' much, then maybe look into the SAN transport mode

  Good luck!

• What is the best way to restore virtual machines after a refresh of the server

  Hi all

  First time poster here. A group of people at my work have their own VMWare environment which they install later. It has 3 virtual machines running on it, and they want to set up a fourth. Unfortunately the new machine, they want to put in place is going to be almost 1 TB in size, and they initially setup the VMFS datastore to 1 MB, which means that a machine can be as large as 256GB.

  Research, it seems that there is absolutely no way to work around this problem, except to redo the data store. Is this correct? If this is the case, I was looking at a way to save the three current machines and to reload them after it is updated. A way that I thought was to go browse the data store and copy all the files on my local machine to the virtual machine (.nvram, hard, .vmx etx... all the files), wipeout and redo the ESXi host with the correct setting of data store, build the machines VMS in vSphere, and then replace the files with those copied. This works perfectly? I don't see a lot of information out there about it and I want to make sure that I have not to spoil the VMs. This environment consists of 1 ESXi host with all the local storage (2 TB).

  Also, if anyone knows a better way to do this, please feel free to give your comments. I would really appreciate it.

  Thank you

  Hello

  Welcome to the community!

  Yes, unfortunately there no way to change the block size of the datastore to vmfs without reformatting.

  If this is the case, I was looking at a way to save the three current machines and to reload them after it is updated.

  Yes, it will work. You have just to copy all files in this VMFS datastore to a place safe and download once the block size has increased. Once the download is complete, navigate to the virtual machine, the virtual machine folder right click and save the VMX.

  You can find the steps to change the size of the block VMFS in this KB. VMware KB: block the size of a VMFS data store limitations

• What are the security issues with a virtual machine?

  The question is in fact a need to install firewalls, antivirus etc. on the virtual machine or the protections on the host protect the virtual machine when it is connected to the internet?

  In General a Virtual Machine that has network connectivity is no different, then a physical Machine with network connectivity and the other must act accordingly.  In other words, a Virtual Machine is subject to the same issues that a physical Machine is when it come to be infected if connected to other physical or virtual systems and or Internet and appropriate precautions should be taken as appropriate and necessary.

• What is the right icc profile for JPEG taken from DNG files?

  Are they always sRGB, or something else? must they assigned to colors to correctly interpret an icc profile? the correct profile is available in the form of metadata can be read using exiftool or such?

  Profile/color space can be anything - there is a tag called "PreviewColorSpace" DNG that allows to:

  • 0 = unknown
  • 1 = gray Gamma 2.2
  • 2 = sRGB
  • 3 = adobe RGB
  • 4 = proPhoto RGB

  Good practice would be to set an ICC profile on the preview, but I don't think that there is no obligation in this regard.

• What is the best color space for workflow photo where the goal is marketing and selling prints?

  What is the best color space for workflow photo where the goal is marketing and selling prints?

  The really important thing here is not work in the color space. The important thing is that you set up your calibration targets so they correspond to the document that you are printing on. This means that the white monitor should be a Visual match white paper and black monitor a match to the density of the ink max for the paper.

  But to answer the question - assuming that you print on an inkjet printer, Adobe RGB should cover most of what the printer can reproduce on a glossy paper of good quality. If you have or get a range wide screen you will also be able to see the range of the file to the screen and you can then test your profile to print with confidence that "what you see is what you get".

  Some will say that good inkjet reproduce some colors that are in fact outside the Adobe RGB, and so you have to work in ProPhoto. While technically true, this superior to Adobe RGB color range is very small and very limited and IMO a fairly minor concern.

• What is the best 'color settings' for documents 4 colors Photoshop 9.0 for eventual printing on a printer? Thanx

  What is the best 'color settings' for documents 4 colors Photoshop 9.0 for eventual printing on a printer? Thank you, Scott

  The 'best' color settings are profile and end points specified by your lithographer. You can see that the work will be produced in CMYK mode, it can specify a RGB. (One of the reasons why it might ask for an RGB file and perform the conversion itself is so that it can prevent its competitors its CMYK settings that apply to the GCR, generation of black [ramp] and limit of total ink regarding specific paper.) Its recommendation may also vary depending on your choice of paper and the surface of the paper. If the choice of the particular lithographer cannot be done at this time, it is generally acceptable to provide the Adobe RGB file with the default settings of Photoshop.

• What are the minimum system requirements for firefox 5 forMac OS x

  When you published Firefox 4, it updated automatically on my Mac PowerPC osx 10.5.x and then would not be executed. I had to look for an earlier version, download and reinstall. It was awkward. I can't find min sys req for the new 5.0 version. Min sys requirements should be obvious in yor press. What is the minimum configuration required for firefox 5.0 for Mac osx, and with more frequent updates, how will I know when you have 'obsolete' another one of my machines, and how would I be protected to an update too far?

  Firefox 4 and 5 will not run on a Mac PPC; only on Intel. You can get the TenFourFox, which runs on a PPC.

• What is the limit of storage for "indexDB" in Firefox 4?

  What is the limit of storage for "indexDB" in Firefox 4?

  I need to know because I write a significant demand with local storage requirements.

  More the 5 MB limit in the Local Storage API.

  Your response is appreciated.

  Thank you
  David

  If the user grants permission for a site to exceed the quota of 50 MB IndexedDB, then as much as I know Firefox is no limit more. The only limits on the size of the IndexedDB database will be the disk space of the user and operating system.

  The quota of localStorage is 5000KB and there is no way for a web site asking the browser for permission to store more than that amount in localStorage.

• What is the best HDMI switch for use with Apple tv 4

  What is the best HDMI switch for use with Apple tv 4. I heard some do not work and the automatic switch has problems because Apple tv is still using power?

  I installed on a cutting and not because the automatic switch works because it isn't always. It came with a remote control that is almost as good, so don't mind the fact that automatic switching does not work well. The reason why I chose cutting is because it was the first device that gave me the good picture and sound quality with my AppleTV, the Xbox 360 and the PS4. (Don't ask!)
