The flashcards below were created by user mikex10a on FreezingBlue Flashcards. What would you like to do?


  1. What is a type 1 hypervisor?
    Type 1 hypervisors run directly on the system hardware and are often referred to as bare-metal hypervisors. ESXi is a type 1 hypervisor.
  2. What is a type 2 hypervisor?
    Type 2 hypervisors require a host operating system. The host OS provides the I/O device support and memory management.
  3. What is the max number of virtual CPUs per host for ESXi 5.5?
    The max number of virtual CPUs per host for ESXi 5.5 is 4,096.

    The max number of logical CPUs for ESXi is is 320.
  5. What is the max number of virtual CPUs per core for ESXi 5.5?
    The max number of virtual CPUs per core for ESXi 5.5 is 32.
  6. What is the max amount of RAM per host for ESXi 5.5
    The max amount of RAM per host for ESXi 5.5 is 4 TB.
  7. VMkernel
    The VMkernal manages the virtual machines' access to physical hardware by providing CPU scheduling, memory management and virtual switch data processing.
  8. processor entitlement
    Processor entitlement is the number of physical processors for which each license is required.

  21. Update Manager
    Option server application and database utility that assists in patching and upgrading hosts and VMs.
  22. Data Recovery
    Agentless disk-based backup system that has de-duplication at the destination and is design for small to medium size organizations.
  23. High Availability
    Automatic restart of VMs if they are a host that fails.
  24. vMotion
    Migration of a VM from one physical host to another without disruption.
  25. Storage APIs for data protection
    Scalable backup without disruption using third party backup software
  26. Virtual serial port concentrator
    Redirects serials ports of VMs so that management traffic is only on the management network.
  27. Hot add
    Allows addition of CPUs and memory without disruption or downtime.
  28. vShield zones
    Allows configuration and maintenance of multiple security zones within software among shared hosts.
  29. Fault Tolerance
    Provides continue availability for VMs with zero data loss.
  30. Storage APIs for array integration
    Improves performance and scalability by leveraging efficient array-based operations.
  31. Storage vMotion
    Migrates VM files across storage arrays while VMs are running.
  32. DRS and DPM
    Automatically balances VM loads across hosts
  33. Storage I/O Control
    Continusouly monitors I/O load of storage volumes and dynamically allocates available I/O resources based on admin settings
  34. Network I/O control
    Prioritizes network access by monitoring I/O load over the network and dynamically allocating available resources to admin specified flows
  35. Distributed switch
    Centralizes provisioning, administration and monitoring of a virtual network with cluster-level aggregation of resources
  36. Host profiles
    Simplifies host deployment and compliance using baselines to automate the configuration of multiple hosts
  37. Auto Deploy
    Allows for deployment of multiple vSphere hosts in minutes by streaming the installation directly into RAM.
  38. Storage DRS
    Provides effective balancing of VMs across datastores in datastore clusters.
  39. Profile-driven storage
    Allows for prioritization of storage options and reduces the steps in the selection of VM storage and ensures that VMs are placed on the right type of storage for each VM.
  40. VMware vCenter Orchestrator Configuration
    controls a workflow engine that can help admins automate existing manual tasks
  41. VMware VirtualCenter Management Web Services
    Configuration for vCenter web management
