How many virtual machines on a single HBA?

Hi all

I understand a VI3 environment for a client, but I doubt if HBA will be a bottle neck for the performance of the virtual machine. I would like to know how much minimum I should recommend? Two enough a primary and another for failover? can you tell us the load balancer for HBA? I read that we can have several number of VMs communicate via a single HBA, however, there will be performance problems? Can anyone share their experiences and their recommendations?

Thank you

Rahul

I've not seen HBA as a bottleneck, especially with the 4 GB HBAs now commonly available.

I only dual port HBA in our blade servers and servers of U 1, I ran 2 x single port HBA.

Main SAN issues, I've had have been a doubtful avalanche Transceiver and a motherboard fault on a Server Blade.

Otehrwise HBAs themselves were enough sound that's why I am not too concerned about the unique dual-port HBA's on the blade.

A lot of the design is subject to redundancy and how much risk / single points of failure, you are willing to tolerate.

  • Create a great metric for virtual machines that shows how many virtual machines on the host parent

    One of the properties of a virtual computer's Parent host.  I would like to pass this info on to a metric Super VM and use to gather the number of VMS are on the associated VM host Parent.   This SM would be so associated with my VMs.

    Is this possible?

    I found this:

    AVG (${adaptertype = VMWARE, objecttype = HostSystem, attribute is summary | total_number_vms, depth =-1})

  • How many virtual machines can be run using the bridge at the same time?

    I'm on Win 7 and XP both in Bridge mode. every time the two machines lights I lose the entire network including the host NIC connection. Once I have change the VM to NAT connection I can resume normal activity. Mode bridge on 2 or more VMs is not a supported configuration? Can someone please clarify? I'd appreciate the help.

    Thank you

    The default value for switch ports is often the "Desktop" mode, which limits access to the only 2 (port security) MAC addresses. If you need more the port need to be configured as a port of "access".

  • Find out how many virtual machines you create a month

    I've been messing around with this script which was published on the vSphere PowerCLI blog but I can't do what I want it. I try to get the output to an html Web page results. Here is the code of the blog:

    Function Get-VMCreationReport {}

    Get - VM | {Group

    If ($_.) CustomFields-as -not $null) {}

    "{0:Y}" -f $_. CustomFields

    } else {}

    }

    I modified it as follows:

    #I have location set because I'm only pulling the VM to a specific host in a folder.

    $VMs = @(get-VM-emplacement "TEST")

    "$html = @".



    "@

    $html = ""test ' "

    The problem is that the output is not posting on the html page. I can see when debug that code runs through the if loop to the right. Any ideas?

    (-) A hash literal to calculate the following property. In this case, the number of elements in the array of the group, which is the number of guests

    (-) all resulting objects to the Select-Object are placed in the pipeline and converted by the ConvertTo-Html cmdlet to HTML

  • How many virtual servers by host machine?

    Hello

    Another question, is there a method to determine how many virtual machines that I can host on one computer? Many people seem to ask this question, but I'm yet to find one another answer that wave "between 10 and 20 virtual machines" or "up to 50 vms' if I know what are my physical features and I know what operating systems and applications I don't want run on virtual servers, is there a way to calculate whether my hardware will be able to host virtual machines?

  • How the Virtual Machine port group communication?

    How the Virtual Machine port group communication?

    Port group is virtual aggregation of ports on vSwitch. A vSwitch can have multiple Port groups which separate the different network traffic. Port groups communicate with vSwitch, and we have physical network maps on vSwitch which establish communication with the external network. We can configure security, NIC teaming, traffic shapping nework political and at the level of the port groups. Once the port group is created, we can assign to vNIC

    How to establish communication?

    Public network > Switch L3 Core > ESXi physical adapter > vSwitch > groups > virtual NIC > Virtual Machine

    Virtual machine connect to the physical map using vNIC coming on Port groups. This is how it works.

  • How do I 'batch' closing of a large number of virtual machines on a single order?

    We have performance issues with some programs that a large number of machines virtual shutdown.  Steve Jin here mentions on his blog that there is a number of API and batch processing.  I can't find on the subject if and would just like to send a command to stop, a large number of virtual machines.  Multi-threading applications for judgment has not been effective or possible.

    If someone could point me to the right direction, I would be grateful.   Thank you!

    Sean Clark - vExpert 2009, VCPX3 - http://twitter.com/vseanclark - http://seanclark.us - http://vmunderground.com

    Hey Sean,

    I'm not familiar with batch API too many orders, but I'm guessing that you're referring to:

    Turning the power on

    Power off

    As you probably know, there are a lot of API command to power on a set of virtual machines, but there is not one to turn off. It maybe an internal/private API to power off the coast, but I have not heard/seen it.

    If your question is around Steve Jin VI Java API, maybe hit him up on top of this blog, you probably a more precise answer and if this isn't the case, I think he'll be able to help directly as well.

  • How many virtual processors on a virtual machine?

    Hi guys,.

    I have ESX35 install on a ML570 G3 with have 4 CPU, active hyperthreading.  In the tab set up, the number of logical processors is 8, by the attached screenshot.  I've lowered to VI3 VI4 and have 4 individual licenses of the CPU.  The sales representative told that the license goes with physical CPU, up to 4 cores per processor.  However when I created a VM, I can only put in place for a maximum of 4 virtual processors.  Is this correct?  I thought that I can assign up to 8 virtual CPUs in each virtual machine.

    THX.

    Hello htt. Unfortunately, to use 8way vSMP you must the Enterprise more than vSphere license. Please see the following page for more information.

  • Deleting the same files of many virtual machines remotely

    Hi all

    I tried to delete the same file several virtual machines remotely using the following script PowerCLI:

    $a = Get - VM | %{

    foreach ($nic as $_.) Guest.Nics) {}
    Write-output $nic. IPAddress
    }
    }
    foreach ($i in $a)
    {$b = get-WmiOBJECT-query "SELECT * from CIM_DataFile where Name='C:\\test\\deleteme.exe'"-computername $i}
    $b.delete)

    }

    It works perfectly when I run the script on the host virtual machines while I am running the script PowerCLI. When I Connect-viserver to another host however and try to run the script, I get the dreaded "RPC server is unavailable error (HRESULT: 0x800706BA)" for Get-WmiObject.  Virtual machines don't have Windows Firewall and have all TCP/IP, RPC and WMI services started, so who could eliminate any possibility.

    I am also able to run other scripts that use the Get-wmiobject across all virtual machines such as scripts to change the DNS or Netbios name across many machines on different hosts.

    Any comments would be greatly appreciated and please feel free to comment if you know maybe other ways which can delete files on multiple virtual machines in any other way.  Installation PowerCLI to run the script locally on each host would be a laborious process to do.

    Thank you very much!

    Best regards

    To solve the problem with the quotes, you can use double quotes inside the string. Like this:

    «del "«c:\documents and settings\text.exe»»»

    Or you can use for the string single quotes and double quotes inside:

    "del"c:\documents and settings\text.exe"

  • Windows 7 - how? -Virtual Machine, Dual Boot

    I used Windows 8 until yesterday, but I decided to upgrade to Windows 7, because it was recommended and it supports all the necessary software that we use.

    I have a virtual machine was a natural choice, but then I struggled with my COM port that did not appear in the virtual computer's Device Manager. I'm desperate

    and almost tried a dual boot, but double boots, you are supposed to install the oldest operating system first! It would mean having to completely uninstall Windows 8.1.

    Am I missing something here? What is the best way to get Windows 7 running on my laptop so I can use the COM ports and use SSH to connect to Hugues paurais?

    Thanks for reading,

    Kevin

    I use Windows 7 on an iMac using Parallels.  It works fine for me.  I do not use the COM ports.  You don't need a com to ssh port.  SSH uses the network, not a serial port.  I think one of the videos showed how to use a com port for your installation of the NIC program.  You don't need to do.  You can get the network IP configuration using a HDMI monitor and a keyboard.
