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 - Dell PowerVault MD3000i | Dell MD Storage Array vCenter Plug-in User’s - Page 6
com/manuals. In addition, system names and IP addresses of vCenter and the Dell MD Storage arrays are required during installation.

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 - Dell PowerVault MD3000i | Dell MD Storage Array vCenter Plug-in User’s - Page 11
that member or members of this role will need. 4 In addition to the permissions selected above, select the appropriate permission from the Storage Administrator group to allow for Read Only or Read Write access to the storage arrays. See Figure 4. Dell MD Storage Array vCenter Plug-in 11 - Dell PowerVault MD3000i | Dell MD Storage Array vCenter Plug-in User’s - Page 12
5 Click OK to apply permissions to the role. NOTE: The administrator role is not editable and, therefore, if the administrator user will be used to manage storage, a new role must be created that has all of the privileges added to it. The administrator user must then be added to this role as - Dell PowerVault MD3000i | Dell MD Storage Array vCenter Plug-in User’s - Page 13
users who will be members of the role. NOTE: To assign permissions to a user, the user must already exist as a valid Windows user. Figure 5. Assign Storage Administrator Role Dell MD Storage Array vCenter Plug-in 13 - Dell PowerVault MD3000i | Dell MD Storage Array vCenter Plug-in User’s - Page 14
or IDs that will require access to the storage arrays. 4 Select the modified role from the Management After the storage administrator role has been defined and the appropriate user IDs have been configured with the role, some final installation tasks might need to be performed.

Networking Configuration for Software iSCSI Storage Networking configuration for software iSCSI involves creating an iSCSI VMkernel port and mapping it to a physical NIC that handles iSCSI traffic. Depending on the number of physical NICs you use for iSCSI traffic, the networking setup can be - Dell PowerVault MD3000i | Dell MD Storage Array vCenter Plug-in User’s - Page 20
activate multipathing for software iSCSI initiator: 1 Identify the names of VMkernel iSCSI ports assigned to physical adapters. The vSphere Client displays the port's name below the network label. Example 1: Figure 13 shows the ports' names as vmk1 and vmk2. 20 Dell MD Storage Array vCenter Plug - Dell PowerVault MD3000i | Dell MD Storage Array vCenter Plug-in User’s - Page 21
VMkernel Ports This example shows how to connect the software iSCSI initiator vmhba33 to VMkernel ports vmk1 and vmk2. 1 Connect vmhba33 to vmk1: esxcli swiscsi nic add -n vmk1 -d vmhba33 2 Connect vmhba33 to vmk2: esxcli swiscsi nic add -n vmk2 -d vmhba33 Dell MD Storage Array vCenter Plug-in 21 - Dell PowerVault MD3000i | Dell MD Storage Array vCenter Plug-in User’s - Page 22
See Figure 15. 4 If the suggested configuration is correct, click OK to apply the changes to the storage array. If the suggestion is not correct, modify the configuration based on the iSCSI zoning rules from the previous ESX Host SAN Configuration section. 22 Dell MD Storage Array vCenter Plug-in - Dell PowerVault MD3000i | Dell MD Storage Array vCenter Plug-in User’s - Page 23
The wizard then displays progress while the requested configuration changes are being made. Close the progress window manually after the changes are complete. See Figure 16. Figure 14.

15. Configure ESX Host to Storage Array Wizard The ESX host has now been configured to the storage array. The next step is to create new virtual disks on the storage array to be used by the ESX host. New virtual disks are created using the Dell Storage vCenter Plug-in. 24 Dell MD Storage Array - Dell PowerVault MD3000i | Dell MD Storage Array vCenter Plug-in User’s - Page 25
Figure 16. Commit Changes Storage Array Summary Clicking on a storage array from the Array Manager View displays a summary of the selected storage array. See Figure 17. This includes information on the status of the storage array, the number of RAID controller modules, the number of failed RAID - Dell PowerVault MD3000i | Dell MD Storage Array vCenter Plug-in User’s - Page 26
shows how storage capacity is allocated. This view also allows you to create new disk groups and virtual disks. Additionally, existing virtual disks and disk groups may be modified or deleted here. To create a new disk group, click the Create Disk Group link. 26 Dell MD Storage Array vCenter Plug - Dell PowerVault MD3000i | Dell MD Storage Array vCenter Plug-in User’s - Page 27

, larger LUNs for the following reasons: • More flexibility to create virtual machines without asking the storage administrator for more space. • More flexibility for resizing virtual disks, doing snapshots, and so on. • Fewer VMFS datastores to manage. 28 Dell MD Storage Array vCenter Plug-in - Dell PowerVault MD3000i | Dell MD Storage Array vCenter Plug-in User’s - Page 29
Service requires that each cluster disk resource is in its own LUN. • Better performance because there is less contention for a single virtual disk. When the storage you plan how to set up your storage for your ESX/ESXi systems before you format LUNs with Dell MD Storage Array vCenter Plug-in 29 - Dell PowerVault MD3000i | Dell MD Storage Array vCenter Plug-in User’s - Page 30
the Adaptive Scheme to Make LUN Decisions When you plan how to set up your storage for your ESX/ESXi systems before you format LUNs with VMFS datastores, you must decide on the the I/O characteristics of the virtual disk. Click OK to create the virtual disk. 30 Dell MD Storage Array vCenter Plug-in - Dell PowerVault MD3000i | Dell MD Storage Array vCenter Plug-in User’s - Page 31
, and the disk group on which to place the repository. After the size of the snapshot exceeds the percentage size of the source virtual disk, the snapshot fails and is no longer available for use until it is re-established with the Recreate Snapshot link.

repository virtual disks. To re-establish the snapshot, click the Recreate Snapshot link, which then creates a new copy of the source virtual disk that may be used. NOTE: Re-creating a snapshot disables the original snapshot before creating a new snapshot. 32 Dell MD Storage Array vCenter Plug-in - Dell PowerVault MD3000i | Dell MD Storage Array vCenter Plug-in User’s - Page 33
virtual disk copy is initiated and the Virtual Disk Copy operation uses the Snapshot virtual disk to establish the virtual disk copy with. This action lets continued readwrite operations to the source virtual disk from the host during the establish period.

tab to present the virtual disks to the ESX host for use. See Figure 25. From this view, you can manage hosts, host groups, and virtual disk mappings. To present a new virtual disk to an ESX host, click the Add Mapping link to start the Add Mapping wizard.
