VMware vSphere
vSphere is the world's most widely used virtualization platform for building cloud infrastructures in the private and public sectors. Consolidation reduces the data center infrastructure at hardware level to a minimum. Hardware utilization easily reaches 80% without any loss of performance compared to a solution without virtualization. Lower space, energy, cooling, hardware and service costs lead to a significant reduction in investment and operating costs.
At system level, this platform offers high-availability mechanisms for mission-critical applications. These meet the highest requirements for service level agreements. The system platform scales with little effort to efficiently meet new operating requirements.
Operating systems that no longer support new hardware platforms can be easily converted to the virtualized platform and operated. The prerequisite is that the system to be migrated is supported on the hypervisor. The compatibility list provides information.
Essential vSphere components
- ESXi is the VMware hypervisor and forms the virtualization layer for the shared use of hardware resources.
- VMware vSphere Virtual Machine File System (VMFS) ensures access to disk resources on local and shared storage systems (such as FC, iSCSI, etc.).
- VMware vSphere High Availability (HA) ensures that in the event of a software problem or hardware failure of a physical host, the virtual instances can be restarted on another host within a very short time.
- VMware vSphere vMotion allows running virtual systems to be moved between physical hosts during operation and without any interruptions. In this way, maintenance work can be carried out on the physical servers without interrupting operations.
- VMware Storage vMotion makes it possible to move virtual disks of a VM to another VMFS store during operation. Migrations to another storage system are possible in this way without any interruptions from the user's point of view.
- VMware vSphere Fault Tolerance (FT) offers uninterrupted availability of a VM in the event of a hardware failure by means of replication (online copy of a VM).
- VMware vSphere Data Protection makes it possible to ensure a cost-effective backup of VMs based on Avamar technology. This is an agentless backup including deduplication of the data in the backup pool. The fee-based VMware vSphere Data Protection Advanced version provides additional functions in terms of online integrations, single item recovery and larger backup capacities.
- VMware vSphere Distributed Resource Scheduler (DRS) ensures the distribution of virtual machines on the physical hosts in an ESX cluster by means of policy-based automation.
- VMware vSphere Storage Distributed Resource Scheduler (Storage DRS) decides on which storage medium the virtual machine data should be stored based on storage properties with regard to performance and based on the requirements of the virtual machine.
- VMware vSphere Distributed Switches simplify network management by means of a higher-level network instance. These switches are a prerequisite for the use of the dynamic Link Aggregation Control Protocol (LACP).
