vSphere 5 - 8

VSA allows features like vMotion, DRS, Storage vMotion, and HA to be possible using only local storage. This enables advanced vSphere capabilities now to be possible for environments as small as just two servers. vSphere provides the VSA environment with tools to monitor and manage performance and understanding the key factors of VSA performance helps drive a successful deployment.

The performance of VSA is directly related to the hardware configuration of the systems used for its cluster. Big differences in capacity, performance, and price exist depending on the exact configuration used. The data replication performed by VSA across its cluster nodes provides high availability, but also has an effect on performance. Testing was done with a mixed workload to examine application performance and infrastructure operations. A set of tests with an I/O generation tool were also run to examine what happens across the hosts in a VSA cluster and to illustrate how to monitor and manage performance.

Performance of VSA in VMware Sphere 5

VMware vSphere 5.0 is a significant milestone for VMware, introducing many new features and capabilities. For many, the road to vSphere 5.0 will begin by upgrading existing vSphere environments. Fortunately, included with the many new features and capabilities of vSphere 5.0 is a simple upgrade path that makes it easy to migrate from VMware vCenter 4.x to vCenter 5.0 and from VMware ESXi 4.x to ESXi 5.0. And for the first time, users have the ability to do an in-place migration from VMware ESX® 4.x to ESXi 5.0. This paper provides an overview of the ESXi 5.0 upgrade process, along with recommendations to help ensure a smooth and seamless transition.

VMware vSphere 5.0 Upgrade Best Practices

This paper describes the architecture of ESXi and then explains how various management tasks are performed in it. This information can be used to help plan a migration to the ESXi architecture from the legacy ESX framework and to improve or enhance day-to-day operations.

VMware's Site Recovery Manager 5 leverages the all inclusive auto replication of the Dell EqualLogic PS Series SAN to create an automated disaster recovery tool. Learn how SRM enables the administrator to develop an entire new DR strategy based on virtualized infrastructure. This first part covers SRM and how to configure replication on the PS Series SAN.

vSphere supports several command‐line interfaces for managing your virtual infrastructure including the vSphere Command‐Line Interface (vCLI), a set of ESXi Shell commands, and PowerCLI. You can choose the CLI set best suited for your needs, and write scripts to automate your CLI tasks.

The vCLI command set includes vicfg- commands and ESXCLI commands. The ESXCLI commands included in the vCLI package are equivalent to the ESXCLI commands available on the ESXi Shell. The vicfgcommand set is similar to the deprecated esxcfg- command set in the ESXi Shell.

You can manage many aspects of an ESXi host with the ESXCLI command set. You can run ESXCLI commands as vCLI commands or run them in the ESXi Shell in troubleshooting situations. You can also run ESXCLI commands from the PowerCLI shell by using the Get-EsxCli cmdlet. See the vSphere PowerCLI Administration Guide and the vSphere PowerCLI Reference. The set of ESXCLI commands available on a host depends on the host configuration. The vSphere Command‐Line Interface Reference lists help information for all ESXCLI commands. Run esxcli --server <MyESXi> --help before you run a command on a host to verify that the command is defined on the host you are targeting.
