vmware

VMWare Cheatsheet

vCloud Director – built on top of vSphere, enables the consolidation of virtual infrastructure across multiple clusters, the encapsulation of application services as portable vApps, and deployment of those services on-demand
vCenter Server – centrally manages VMware vSphere environments
vSphere – combination of products below, based on licensing level
- Compute
  - ESX – OS-based hypervisor
  - ESXi – bare-metal hypervisor
  - Distributed Resource Scheduler (DRS) – continuously monitors utilization across a resource pool and intelligently allocates available resources among virtual machines according to business needs
  - Distributed Power Management (DPM) – continuously optimizes power consumption in the datacenter, by dynamically powering on/off VMs
- Storage
  - VMFS – Virtual Machine File System
  - Thin Provisioning – allows over-allocation of storage capacity for increased storage utilization
  - Storage I/O Control – enables a pre-programmed response to occur when access to a storage resource becomes contentious
- Network
  - Distributed Switch – simplifies virtual machine networking by enabling you to set up virtual machine networking for your entire datacenter from a centralized interface
  - Network I/O Control – configure rules and policies to specify the business priority of each VM. When I/O congestion is detected, Network I/O Control dynamically allocates the available I/O resources to flow types according to your rules
- Availability
  - vMotion – live migration
  - Storage vMotion – enables you to perform live migration of virtual machine disk files across heterogeneous storage arrays
  - High Availability – provides cost effective, automated restart within minutes for all applications in the event of hardware or operating system failures
  - Fault Tolerance – provides continuous availability for applications in the event of server failures, by creating a live shadow instance of a virtual machine that is in virtual lockstep with the primary instance
  - Data Recovery – protects against data loss in your virtual environment by enabling fast backups to disk and, more importantly, fast and complete recovery
- Security
  - vShield Zones – simplifies application security by enforcing corporate security policies at the application level in a shared environment, while still maintaining trust and network segmentation of users and sensitive data
  - VMSafe – enables the use of security products that work in conjunction with the virtualization layer to provide higher levels of security to virtual machines than even physical servers
- Scalability
  - DRS – see above
  - Hot Add – enables CPU and memory to be added to virtual machines when needed without disruption or downtime
Infrastructure & Operations Management
- vCenter Operations – automate performance, capacity and configuration management. It collects and analyzes performance data, correlates abnormalities and identifies the root cause of building performance problems
- Site Recovery Manager – leverages cost-efficient vSphere Replication or storage-based replication to provide: replication of applications to a secondary site, management of recovery and migration plans, non-disruptive testing, and fully automated site recovery and migration
- CapacityIQ – Optimize utilization of existing hardware resources, Plan for potential business and service disruptions proactively by modeling the impact of an outage, failure or disaster, and Model the effect of one-time strategic business changes.
- Configuration Manager – policy-driven automation detects deep system changes and identifies whether that change is within policy or whether it has created a compliance violation or security vulnerability
- Orchestrator – provides out of the box workflows that can help administrators automate existing manual tasks.
- Converter – formerly P2V
- Lab Manager – Provide automated management of highly transient and highly cloned virtual environments
Business Management
- Chargeback – automate chargeback with VM consumption data from vCenter or vCloud Director
- Service Manager – automates IT Service Management processes in enterprise organizations
