Dell MD Storage Array vCenter Plug-in 5

Overview

The Dell MD Storage Array vCenter Plug-in is a VMware vCenter 4.0 plug-in

that provides integrated management of Dell MD Storage Arrays within

vCenter. The plug-in will allow the vCenter administrator to configure ESX

hosts to 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. The plug-in utilizes an application

server to facilitate the interface between the vSphere Client and the Dell

storage array based on the authenticated logged-in user and the permissions

assigned to that user's role.

NOTE: The Dell Storage Array vCenter Plug-in requires that a vCenter Server be

installed within the environment. The plug-in will not function in a vSphere Client

and ESX host-only configuration.

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

support.dell.com/manuals

In addition, system names and IP addresses of vCenter and the Dell MD

Storage arrays are required during installation. Use the following table as a

template to document the system names and IP addresses of the equipment

to be used during the installation process.

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. For this reason, it is recommended

that you limit the size of the storage arrays and number of objects to be

managed. The following are the recommended maximums for this release of

the plug-in. The number of systems being managed and the number of virtual

disks and physical disks on each system will determine the overall

performance of the plug-in.

Recommended maximum configuration:

• 10 Dell MD Storage Arrays

• 256 Objects per array (Virtual Disks, Virtual Disk Copies, or Snapshots)

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.

NOTE: It is highly recommended that the application server be installed on a

separate Windows 2003 or 2008 server from the existing VMware vCenter Server.

However, the application server may be installed on the same host as the existing

vCenter Server if adequate resources are available on the vCenter Server.

After the Dell Storage vCenter Plug-in software has been downloaded, run

the package on the application server to launch the installation wizard. The

installation wizard will install a Jetty application server, SMI-S provider, and

equipment in the environment, such as IP addresses and DNS names, must

be supplied during the installation process. The above table may be used to

help facilitate recording this information for the installation. Follow the

procedure below to install the software:

Read the introduction screen, and click

Read through the license agreement and if you accept the terms, select the

appropriate option, and click

Either select the local installation directory for the plug-in manager, or

click

for the default.

Review the installation details, and click

Install

if the details are correct.

Change the port number of the Jetty server if you wish to, or accept the

default of 8084 and 8081, and click

Change the IP address of the application server if desired. The IP address

will default to the IP address of the system the installer is running on.

Click

The next screen prompts you for the IP address of the vCenter server that

the plug-in will be installed on. Enter the IP address of the vCenter server,

and click

Enter the Administrator's email address for alerts, and click

Enter the vCenter Administrator's User ID, and click

Enter the vCenter Administrator's password, and click

The installation is now complete. Click

Done

to close the installation

wizard.

NOTE: To verify successful installation of the application server, run services.msc,

and verify that the cimserver service has been installed and has started along with

the Jetty6-Service service. Also note that after the application server has been

rebooted, the name of the CIMOM service will change to Pegasus CIM Object

Manager.

Application and vCenter Server Configuration

After the application server has been installed, verify the Dell Storage

vCenter Plug-In has been successfully registered with the vCenter server.

Open a vSphere Client to the vCenter Server, and select Plug-insManage

Plug-ins. You should see the Dell Storage vCenter Plug-In listed as enabled. If

it is listed as disabled with an error message stating that it cannot

communicate with the application server, verify that the port number defined

for the Jetty server is enabled to pass through any firewalls that may be in use.

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.

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.

Modifying or Creating a Role

To modify the user role, follow the procedure below:

Select the role to modify from
