vSphere 5 documentation notes

vReference.com

Here are my condensed notes for the vSphere 5.0 documentation. They’re excerpts taken directly from VMware’s own official documentation. These notes aren’t meant to be comprehensive, or for a beginner; just my own personal notes. They’re snippets I found interesting while reviewing the official VMware documentation. I hope you find them useful.VMware vSphere Basics (ESXi 5.0 & vCenter 5.0)
o Virtualization Layer — includes infrastructure services and application services. o Infrastructure services: Compute services Storage services Network services o Application services are the set of services provided to ensure availability, security, and scalability for applications. Examples include vSphere High Availability and Fault Tolerance. Inaddition to the Virtualization Layer, there is also the Management Layer and the Interface Layer. VMware vSphere Web Client — A Web interface that enables users to connect remotely to vCenter Server from a variety of Web browsers and operating systems. VMware Storage DRS — Allocates and balances storage capacity and I/O dynamically across collections of datastores. This feature includes managementcapabilities that minimize the risk of running out of space and the risk of I/O bottlenecks slowing the performance of virtual machines. A datastore cluster is an aggregation of multiple datastores into a single logical, load-balanced pool. Storage DRS helps you manage multiple datastores as a single compute resource, called a datastore cluster. A datastore cluster is an aggregation of multipledatastores into a single logical, load-balanced pool. You can treat the datastore cluster as a single flexible storage resource for resource management purposes. In effect, a datastore cluster is the storage equivalent of an ESXi compute cluster. You can dynamically populate datastore clusters with datastores of similar characteristics. You can assign a virtual disk to a datastore cluster andStorage DRS finds an appropriate datastore for it. The load balancer manages 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 bottlenecks slowing the performance of virtual machines. Network resource pools determine the priority different network traffic types are given on avDS. When network resource management is enabled, vDS traffic is divided into the following network resource pools: FT traffic, iSCSI traffic, vMotion traffic, management traffic, NFS traffic, and virtual machine traffic (Forbes: There are now 2 newly defined pools, see the Networking sections for details). You can control the priority for the traffic from each of these network resource pools bysetting the physical adapter shares and host limits for each network resource pool. VMware vShield is a suite of security virtual appliances built to work with vSphere. o vShield Zones — provides firewall protection for traffic between virtual machines. o vShield Edge — provides network edge security and gateway services to isolate the virtual machines in a port group, vDS port group, or Cisco Nexus1000V. o vShield App — an interior, vNIC-level firewall that allows you to create access control policies regardless of network topology. o vShield Endpoint — delivers an introspection-based antivirus solution. Administrative functions are available to the vSphere user through the vSphere Client, with full functionality, and the vSphere Web Client, with a subset of that functionality. vSphereClient: o For infrastructure configuration and day-to-day operations: Locally installed application Windows operating system only Can connect to vCenter Server or directly to hosts Full range of administrative functionality o Users: Virtual infrastructure administrators for specialized functions vSphere Web Client: o For day-to-day operations Web application Cross platform Can connect to vCenter...
