Imposes constraints on resource usage and any action that would violate these constraints is not permitted.
Privileges control operations related to ESX Agent Manager and agent virtual machines.
All Paths Down- A datastore is shown as unavailable in the Storage view. Dead or error.
pre-configured virtual machine image, ready to run on a hypervisor
ESXi installs directly onto your physical server enabling it to be partitioned into multiple logical servers referred to as virtual machines.
non-volatile firmware used to perform hardware initialization during the booting process (power-on startup) and to provide runtime services for operating systems. Basic input output systems
Datastore cluster privileges control the configuration of datastore clusters for Storage DRS.
Direct Console User Interface. The dcui user runs on hosts and acts with Administrator rights.
Dedicated Failover Host
With dedicated failover hosts admission control, when a host fails, vSphere HA attempts to restart its virtual machines on any of the specified failover hosts.
Domain Name System
Distributed Resource Scheduler
deploying and serving virtual computers. (host)
Incase a host fails, everything gets sent to another host.
Provides continuous availability for virtual machines by creating and maintaining a Secondary VM that is identical to, and continuously available to replace, the Primary VM in the event of a failover situation.
You can supply a name for that new top-level resource pool. The default is Grafted from <host_name>.
OS is installed directly into the VM.
the OS installed onto the VM that doesn't affect the physical device
HA (High Availability)
Ensures that sufficient resources in the cluster are reserved for virtual machine recovery in the event of host failure.
vSphere HA can monitor hosts when a management network partition occurs and continue to respond to failures.
the hardware that provides it with computing resources such as processing power, memory, disk and network I/O (input/output), and so on.
computer software, firmware or hardware that creates and runs virtual machines.
a protocol that uses the TCP to transport SCSI commands, enabling the use of the existing TCP/IP networking infrastructure as a SAN. ( Internet Small Computer Systems Interface)
how network traffic is distributed between a physical and virtual machine.
provides progress status for the creation and downloading of the support bundle from each source.
LUN queue depth
the maximum number of ESX/ESXi VMkernel active commands supported by the LUN.
Network Filesystem Storage
Network Time Protocol
raises the consolidation ratio, increases operational efficiency, and lowers total cost of operating virtual machines.
Permanent Device Loss- A storage device is considered to be in the permanent device loss state
Reset to green
An alarm triggered by an event might not reset to a normal state if vCenter Server does not retrieve the event that identifies the normal condition
Ensures that a resource pool has sufficient resources to satisfy the reservations, shares, and limits of all virtual machines associated with it.
a storage feature integrated into vSphere (Storage Area Network)
(Systems Management Architecture for Server Hardware)
provide network connectivity to hosts and virtual machines
helps you visually represent and understand the relationships between an inventory object
lists log files associated with vmware system
alarms that went off
provides centralized management and operation, resource provisioning and performance evaluation of virtual machines residing on a distributed virtual data center.
vSphere Client is installed on laptop or desktop PC and is used to access ESXi Server to install and manage virtual machines on ESXi server
vCenter server is installed as virtual machine on top of ESXi server.
VMware vSphere Distributed Switch
a software computer that, like a physical computer, runs an operating system and applications.
to create a virtual version of a device or resource, such as a server, storage device, network or even an operating system where the framework divides the resource into one or more execution environments.
VM boot order
the order the vm's boot up and anything else on the VM
Virtual Machine Component Protection
Virtual Machine File System
special constructs used by the vSphere host to communicate with the outside world
Volume Snapshot Service
VMRC VMware Remote Console
VMFS (Virtual Machine File System)
is VMware, Inc.'s clustered file system used by the company's flagship server virtualization suite, vSphere. It was developed to store virtual machine disk images, including snapshots.
High Availability (HA)
A clustering solution to provide resource reliability and availability.
