    Dell MD Storage Arrays, create, map, delete storage virtual disks from the Dell MD Storage Array to the ESX host, and view the vCenter datastores to Dell storage array virtual disks. The plug-in will also allow for the creation of hardware Snapshots, and Virtual Disk Copies, if these premium features are enabled on the storage array.
  • Page 6: Installation Requirements

    Installation Requirements The following requirements must be met in order to install and use the Dell MD Storage Array vCenter Plug-in. • VMware vCenter 4.x server (installed) • Dell storage array with VMware certified firmware • An application server running an MD Storage Array vCenter Plug-in supported operating system as defined in the Support Matrix at support.dell.com/manuals.
  • Page 7: Recommended Configurations

    Storage Administrator User Recommended Configurations The Dell MD Storage Array vCenter Plug-in utilizes SMI-S to communicate with the storage arrays that will be managed within the vSphere infrastructure. Due to the nature of the SMI-S protocol, numerous procedure calls must be made to obtain and send changes to the storage array, which require large amounts of data to be passed between the storage arrays, application server and vSphere Client.
  • Page 8: Software Installation

    Software Installation Obtain the correct version of the Dell Storage vCenter Plug-in for your environment (x86 or x64) from the Download and Drivers area at support.dell.com. See the Support Matrix at support.dell.com/manuals for the most current versions. The file should be copied to the application server.

    The default Jetty TCP port number is 8084 and 8081. After the application server and vCenter server have been configured, you should now see the Dell Storage vCenter Plug-in icon on the home page of the vSphere Client under the Solution and Application section as shown in Figure 2.
  • Page 10: Configuring The Storage Administrator Role

    Figure 2. vCenter Plug-in Configuring the Storage Administrator Role By default, all defined vCenter user IDs will have no rights to the Dell storage arrays. This means that any user that requires read or read/write permissions will need to have their role modified to access the Dell vCenter Plug-in.
