Before you can create a VSA cluster, you must prepare your environment by installing and configuring the hardware and software components. vSphere Storage Appliance Planning ChecklistYou should decide on the scale and capacity of the VSA cluster and also consider some setup limitations. VSA Cluster RequirementsMake sure that your environment meets the hardware and configuration requirements to create a VSA cluster. Configure RAID on a Dell ServerFor Dell servers, you use the Dell PowerEdge RAID Controller (PERC) to create a RAID volume that uses all physical disks on a server. Configure RAID on an HP Server Create a RAID logical volume that uses all physical disks on a server. Configure VLAN IDs on the Ethernet SwitchesTo make use of traffic isolation, you should configure separate VLAN IDs for the front end and back end networks of the VSA cluster. ESXi Installation and ConfigurationAll host that you plan to include in a VSA cluster must have ESXi of the same version installed. vCenter Server InstallationvCenter Server allows you to centrally manage hosts from either a physical or virtual Windows machine, and enables the management of a VSA cluster as well as the use of advanced features such as vSphere High Availability (HA), vSphere vMotion, and vSphere Storage vMotion. Create a Datacenter and Add Hosts in the vSphere Web ClientBefore you create a VSA cluster, you must create a datacenter and add ESXi hosts in vCenter Server. Install VSA ManagerVSA Manager is a plug-in for the vSphere Web Client that you use to create and manage a VSA cluster. VSA Manager also installs the VSA cluster service on the vCenter Server machine or on a server of your choice. Uninstall VSA ManagerYou can uninstall VSA Manager if you have deleted the VSA cluster and no longer use the plug-in for maintenance and monitoring. Installing and Running VSA Cluster ServiceThe VSA cluster service is required by a VSA cluster with two members. You can install the service separately on a variety of 64-bit operating systems, including Windows Server 2003, Windows Server 2008, Windows 7, Red Hat Linux, and SUSE Linux Enterprise Server (SLES). Enable VSA Access for the vSphere Web ClientYou use the vSphere Web Client to connect to a vCenter Server system in a web browser. To be able to manage VSA clusters, you need to activate VSA access for the vSphere Web Client. Enable the VSA Manager Plug-In in the vSphere Web ClientYou must enable the VSA Manager plug-in if the VSA Manager page does not appear for a datacenter object. Modify URL for VSA HelpUse this procedure if you need to change the default URL to VSA Help.
