takes care of initial placement and future migrations based on workload
measurements. Storage space balancing and I/O balancing minimize the risk
of running out of space and the risk of I/O bolenecks slowing the
performance of virtual machines.
vSphere Fault Tolerance
vSphere Fault Tolerance provides continuous availability for virtual
machines by creating and maintaining a Secondary VM that is identical to
the Primary VM. This Secondary VM is continuously available to replace the
Primary VM in a failover situation.
vCenter Server Plug-Ins
vCenter Server plug-ins extend the capabilities of vCenter Server by providing more features and functions.
Some plug-ins are installed as part of the base vCenter Server product.
vCenter Storage
Monitoring
Allows you to review information on storage use and to map relationships
visually between all storage entities available in vCenter Server.
vCenter Hardware
Status
Uses CIM monitoring to display the hardware status of hosts that
vCenter Server manages.
vCenter Service Status
Displays the status of vCenter services.
Some plug-ins are packaged separately from the base product and require separate installation. You can
update plug-ins and the base product independently of each other. VMware modules include:
vSphere Update
Manager (VUM)
Enables administrators to apply updates and patches across ESXi hosts and
all managed virtual machines. Administrators can create user-dened
security baselines that represent a set of security standards. Security
administrators can compare hosts and virtual machines against these
baselines to identify and remediate systems that are not in compliance.
vShield Zones
An application-aware rewall built for vCenter Server integration. vShield
Zones inspects client-server communications and communications between
virtual machines to provide detailed trac analytics and application-aware
rewall partitioning. vShield Zones is a critical security component for
protecting virtualized data centers from network-based aacks and misuse.
vRealize Orchestrator
A workow engine that enables you to create and run automated workows
in your vSphere environment. vRealize Orchestrator coordinates workow
tasks across multiple VMware products and third-party management and
administration solutions through its open plug-in architecture.
vRealize Orchestrator provides a library of workows that are extensible.
You can use any operation available in the vCenter Server API to customize
vRealize Orchestrator workows.
