2011 blog statistics (review)

The WordPress.com stats helper monkeys prepared a 2011 annual report for this blog.

Here’s an excerpt:

The concert hall at the Syndey Opera House holds 2,700 people. This blog was viewed about 26,000 times in 2011. If it were a concert at Sydney Opera House, it would take about 10 sold-out performances for that many people to see it.

EVC for 3DNow! (special case)

Future generations of AMD processors will not include 3DNow! CPU instructions. EVC mode is updated accordingly to hide this feature from older generation’s processors. So hosts which have 3DNow! Instructions will not be compatible with future generations AMD processors unless EVC mode is enabled. As future generation AMD processors will not have 3DNOW CPU instructions. So EVC mode must be enabled for vMotion compatibility between 3DNow! And Not 3DNow! CPU instructions. All AMD Opteron generations 3 are no 3DNow. Generations1 and 2 cannot be made vMotion compatible with hosts that have 3DNow! Instructions

  • AMD Opteron Gen.3 (no 3DNow) cannot be enabled while there are powered ON Virtual Machines in the cluster
  • Either migrate virtual machines out of the cluster or power off them. Migration only allows you to schedule a more convenient down time for virtual machine.
  • Configure EVC cluster by editing VMware EVC settings
  • If you have migrated virtual machines out of the cluster, power them off and cold migrate them back into the cluster.refer point 1

     

    CPU compatibility masks allows per virtual machine customization of CPU features visible to virtual machine

    vCenter compares CPU features of Virtual machine with that of CPU features of the destination host to determine whether to allow or disallow migrations. In cases where you have to decide whether to maintain vMotion compatibility or enhanced CPU feature which guest OS might need, VMware provides check-box to configure individual Virtual Machine.You can configure more advance features as well at the bit level.

    Refer below to reading column. It displays RPM for fan and Voltage in volts

    Hardware status Tab when connected through vCenter. See the complete System Summary below.

    It informs us on what is BIOS Version

    Asset tag

    Serial Number

    Alerts and warning count

    When the client system is unable to resolve the domain

    name of the vCenter Server system. Either fix the domain name resolution

    problem, or edit the file C:Program FilesVMwareInfrastructure

    VirtualCenter Serverextensionscim-uiextensions.xml on the

    vCenter Server system and replace the vCenter Server domain name with its

    IP address. Below is the file but unable to see vCenter name

    About License Key Capacity

    About License Key Capacity

    Thursday, January 06, 2011

    License keys have a certain amount of capacity. For hosts, capacity is based on the number of processors in the

    host. For vCenter Server, capacity is based on the number of instances of vCenter Server. However, the licensing

    of solutions can be based on processors, asset instances, virtual machines, etc.

    Though licensing is applicable to solutions as well as ESX/ESXi hosts and vCenter Server, solutions licensing

    management is too variable and, therefore, specific to each solution to be discussed in general terms.

    Licensing for Each Processor

    You can assign and reassign the processor capacity to any

    combination of hosts. For example, suppose you purchase a 10-processor vSphere license key. You can assign

    the 10-processor license key to any of the following combinations of hosts:

    1. Five 2-processor hosts

    2. Three 2-processor hosts and one 4-processor host

    3. Two 4-processor hosts and one 2-processor host

    4. One 8-processor host and one 2-processor host

    IMPORTANT When you purchase a license, you select the edition, the number of CPUs, and the maximum number of cores per CPU. For example, if you purchase an enterprise license with 100 CPUs, you must also choose the maximum number of cores per CPU.
