What is VMware Distributed Power management?
VMware Distributed Power Management (VMware DPM) provides additional power savings beyond this initial benefit by dynamically consolidating workloads even further during periods of low resource utilization. Virtual machines are migrated onto fewer hosts and the unneeded ESX hosts are powered off.
What is DRS in vSphere?
VMware vSphere® Distributed Resource Scheduler™ (DRS) is the resource scheduling and load balancing solution for vSphere. DRS works on a cluster of ESXi hosts and provides resource management capabilities like load balancing and virtual machine (VM) placement.
What are the four major resource types that vSphere administrators must effectively manage for an efficient virtualized datacenter choose four?
Resource Types Resources include CPU, memory, power, storage, and network resources. Note ESXi manages network bandwidth and disk resources on a per-host basis, using network traffic shaping and a proportional share mechanism, respectively.
What is VM fault tolerance?
VMware vSphere Fault Tolerance (FT) provides continuous availability for applications (with up to four virtual CPUs) by creating a live shadow instance of a virtual machine that mirrors the primary virtual machine.
What is EVC VMware?
VMware Pages You can use the Enhanced vMotion Compatibility (EVC) feature to help ensure vMotion compatibility for the hosts in a cluster. EVC ensures that all hosts in a cluster present the same CPU feature set to virtual machines, even if the actual CPUs on the hosts differ.
What is ESXi cluster?
A vSphere cluster is a set of ESXi hosts configured to share resources such as processor, memory, network and storage. In vSphere environments, each cluster can accommodate a maximum of 32 ESXi hosts, with each host supporting up to 1024 VMs.
What are the three controls mechanisms used by VMware for resource allocation?
Use the resource allocation settings (shares, reservation, and limit) to determine the amount of CPU, memory, and storage I/O resources provided for a virtual machine.
What is FT in vCenter?
The VMware vSphere Fault Tolerance (FT) feature provides high availability (HA) at a higher level and enables you to protect virtual machines without any loss of data or connections. You must enable or disable vSphere FT for the virtual appliance for VSC, VASA Provider, and SRA from your vCenter Server.
What is snapshot in VMware?
A VMware snapshot is a copy of the virtual machine’s disk file (VMDK) at a given point in time. Snapshots provide a change log for the virtual disk and are used to restore a VM to a particular point in time when a failure or system error occurs. Snapshots alone do not provide backup.
