vSphere 5 concepts to remember

Platform roles and inventory

ESXi is VMware's bare-metal hypervisor. It runs virtual machines directly on physical server hardware and provides virtual CPU, memory, storage, and network devices to guest operating systems.

vCenter Server is the centralized management platform for ESXi hosts and virtual machines. It provides inventory management, permissions, templates, clustering, vMotion coordination, DRS, HA configuration, alarms, tasks, and events. An ESXi host can run virtual machines without vCenter, but centralized cluster features require vCenter management.

A typical inventory relationship is datacenter → cluster → hosts and resource pools → virtual machines. A virtual machine can be placed in a resource pool or directly at the cluster level. Datacenters, clusters, hosts, resource pools, and virtual machines are not equivalent sibling objects; their placement affects resource management and permissions.

Provisioning and virtual machine configuration

Virtual hardware compatibility determines which virtual hardware features and host versions a virtual machine can use. Upgrade compatibility deliberately rather than treating a virtual hardware upgrade as a routine change.

VMware Tools improves guest integration through optimized drivers, time synchronization options, graceful shutdown and restart operations, heartbeat information, and improved mouse or display behavior where supported.

A template is a protected master image used to deploy consistent virtual machines. Cloning creates a separate virtual machine from an existing VM or template. Configure the guest operating system's vCPUs, memory, disks, network adapters, and resource settings according to measured workload needs; assigning excessive virtual hardware can also create scheduling overhead.

A snapshot records point-in-time virtual machine state for short-term testing, rollback, or maintenance. It is not a backup, does not make a datastore larger, and should not be retained indefinitely because snapshot delta files can grow and affect performance and available capacity. Consolidate or remove snapshots after the planned operation and verify datastore space first.

Compute and migration features

Feature comparison

vMotion — Live migration of a running VM between hosts — Planned host maintenance or workload balancing — Moves compute execution; it requires suitable host compatibility and networking.

Storage vMotion — Moves VM files between datastores while the VM remains running — Datastore capacity or performance maintenance — Changes storage placement rather than host execution.

DRS — Balances workloads across hosts in a cluster — Resource contention or maintenance — Uses cluster resource information and can recommend or automate vMotion.

HA — Restarts affected VMs after an ESXi host failure — Host failure protection — Provides restart availability, not continuous execution.

FT — Maintains a continuously available secondary execution state for supported workloads — Stronger protection for selected critical VMs — Has stricter compatibility, sizing, and feature constraints than HA.

EVC — Masks processor features to establish a common CPU baseline — vMotion between hosts with different processor generations — Improves CPU compatibility but cannot overcome every architectural or configuration difference.

Resource allocation settings

Shares — Relative priority during contention — They matter only when competing workloads need the same constrained resource.

Reservation — Guaranteed minimum CPU or memory — Use when capacity must be guaranteed and the cluster can satisfy the commitment.

Limit — Maximum CPU or memory consumption — Use only when an intentional ceiling is required; an unnecessarily low limit can cause poor performance.

Availability and storage

HA monitors hosts and virtual machines and can restart affected workloads after a host failure. Admission control reserves enough cluster capacity for the selected failure policy. Datastore heartbeating gives HA an additional way to assess host and VM availability when management network communication is disrupted. Host isolation response, VM restart priority, datastore access, and available failover capacity all affect the outcome.

FT is different from HA: HA normally causes a VM restart on another host after failure, while FT is designed to continue execution through a synchronized secondary for supported workloads. FT constraints must be checked before selecting it.

VMFS is VMware's clustered filesystem for block-storage-backed datastores such as Fibre Channel, iSCSI, or supported local storage. Multiple ESXi hosts can access a VMFS datastore when the underlying storage is presented correctly. NFS is a file-based datastore accessed through an NFS export from a NAS or file server. NFS access depends on network reachability, export permissions, and correct host mounting configuration.

Storage multipathing provides more than one path between an ESXi host and block storage. Verify adapter and fabric connectivity, zoning or target access, LUN presentation, path state, and the selected path policy. Multipathing improves resilience and may improve access distribution, but it does not fix an incorrectly presented or unmounted datastore.

Cluster features require common infrastructure. For example, HA restart protection generally requires surviving hosts to access the VM's files, while vMotion requires the destination host to access the VM's storage or use a supported migration path.

Virtual networking

A standard switch is configured independently on each ESXi host. A distributed switch is centrally managed through vCenter and can provide consistent port configuration across participating hosts. In both designs, a port group applies network connection policy to virtual machine or VMkernel interfaces, while physical uplinks connect the virtual switch to physical network adapters.

A VMkernel adapter is an ESXi host interface for services such as management, vMotion, and storage traffic. Configure the correct port group, VLAN, IP settings, and enabled service, then confirm reachability between participating hosts. Management, vMotion, and storage networks may be separated for security, performance, and fault isolation.

Security and operations

Authentication verifies identity; authorization determines which actions that identity may perform. vCenter permissions combine a user or group, a role containing privileges, and an inventory object where the permission is applied. Use least privilege: create or select a role with only the required operations, apply it at the narrowest suitable inventory level, and validate effective access with a non-administrative account. Separating provisioning, security, and operational responsibilities reduces accidental or unauthorized changes.

Events record significant conditions, tasks show operations and their status, performance data shows resource behavior over time, and alarms actively notify administrators when defined conditions occur. Use them together: an alarm may identify a symptom, the event and task history can show what changed, and performance data can confirm whether contention or saturation is involved.

Configuration checklists

Create and configure a cluster

  • Place compatible ESXi hosts under the correct datacenter and cluster.
  • Enable or evaluate DRS according to the workload and automation policy.
  • Enable or evaluate HA and select an admission control policy.
  • Verify shared datastore access, management connectivity, compatible networking, and host compatibility.
  • Review host isolation response, VM restart priorities, datastore heartbeating, and available failover capacity.

Configure a resource pool

  • Create the resource pool at the appropriate cluster or host inventory level.
  • Place the intended virtual machines in the pool and confirm the hierarchy.
  • Assign shares according to relative workload priority.
  • Use reservations only when CPU or memory capacity can be guaranteed.
  • Avoid restrictive limits unless an intentional maximum is required.

Prepare for live migration

  • Confirm vCenter Server manages both participating hosts.
  • Confirm compatible processors or configure an appropriate EVC baseline.
  • Create or verify a VMkernel adapter with the vMotion service enabled.
  • Check IP reachability, VLAN consistency, and physical uplink connectivity.
  • Confirm datastore access on the destination host or select a supported migration method.

Configure VMkernel networking

  • Create the appropriate VMkernel adapter.
  • Assign the required port group and VLAN.
  • Enable the applicable service, such as management or vMotion.
  • Configure addressing and confirm IP connectivity between participating hosts.

Configure permissions

  • Create or select a role containing only the required privileges.
  • Apply the role at the appropriate inventory level.
  • Check inheritance and any permissions that may override expectations.
  • Validate effective permissions with a non-administrative account.

For a self-check, compare your selections with the answer review below. A correct response demonstrates the applied decision described in the explanation; an incorrect response indicates the topic to revisit.

Answer review

  1. Correct answer: B. vCenter Server centrally manages ESXi hosts and provides inventory, permissions, clusters, HA, DRS, and coordinated migrations.
  2. Correct answer: B. Snapshots are temporary point-in-time aids for testing or rollback. They are not backups and long retention can consume datastore capacity and affect performance.
  3. Correct answer: B. EVC presents a common CPU feature baseline so compatible migrations can occur across processor generations. It must be planned for the cluster's host capabilities.
  4. Correct answer: A. HA needs admission-control capacity and surviving hosts that can access the affected VM's files. Heartbeating and failure-response settings also help HA interpret host conditions.
  5. Correct answer: B. FT is designed for continuous availability of supported workloads. HA normally restarts a VM after failure and therefore does not provide the same continuity.
  6. Correct answer: A. Storage vMotion moves VM files between datastores while the VM remains powered on, provided the destination and migration prerequisites are satisfied.
  7. Correct answer: A. Investigate the complete storage path: adapters and fabric or network connectivity, presentation and permissions, multipathing, datastore mounting, and host rescans.
  8. Correct answer: B. Standard switches are configured per host; distributed switches are centrally managed through vCenter and can maintain consistent policies across hosts.
  9. Correct answer: B. A custom least-privilege role supports separation of duties and reduces the risk of unnecessary changes. Apply it only where the technician needs access.
  10. Correct answer: A. Contention requires evidence-based review of shares, reservations, limits, resource-pool placement, host usage, performance history, and DRS behavior.
