Related concepts Storage Center Server Administration SMI-S Unisphere Central supports the Storage Management Initiative Specification (SMI‐S), a standard interface specification developed by the Storage Networking Industry Association (SNIA). SMI-S allows Unisphere Central to interoperate with storage management software and hardware from other vendors. NOTE: The Storage Manager Data Collector must be installed in a Microsoft Windows environment. SMI-S is not supported on a Virtual Appliance.
2 Getting Started To manage multiple Storage Centers, open a web browser and connect to the Data Collector. To manage a single Storage Center, open a web browser and connect directly to the Storage Center. Topics: • • • Connect to Multiple Storage Centers Using Unisphere Central Connect Directly to a Storage Center Using Unisphere Next Steps Connect to Multiple Storage Centers Using Unisphere Central Start a web browser and use it to connect to the Data Collector.
Next Steps This section describes some basic tasks that you may want to perform after your first log on to Unisphere. These tasks are configuration dependent and not all tasks are required at all sites. Add Unisphere Users Depending on your configuration, you can add users to your system using the Data Collector or you can create local users on the Storage Center using Unisphere.
3 Storage Center Overview Storage Center Hardware Components Storage Center consists of one or two controllers, switches, and might include one or more disk enclosures. Controllers A Storage Center controller provides the central processing capability for the Storage Center Operating System and managing RAID storage. A Storage Center is typically configured with a pair of controllers. In a dual-controller Storage Center configuration, the two controllers must be the same model.
Volumes A Storage Center volume is a logical unit of storage that can represent more logical space than is physically available on the Storage Center. Before data can be written to a volume, it must be mapped to a server, then formatted as a drive. Depending on the configuration of the server, data can be written to the volume over iSCSI, Fibre Channel, or SAS. The storage type and storage profile selected when the volume is created determines how a volume behaves.
Redundancy Requirements Drive size is used to determine the redundancy level to apply to a tier of drives. If any drive in a tier surpasses a threshold size, a specific redundancy level can be applied to the tier containing that drive. If a redundancy level is required, the Storage Center operating system sets the level and it cannot be changed. Table 2.
Disk Classes Disks are classified based on their performance characteristics. Each class is shown in a separate folder within the Assigned disk folder. • Hard Disk Drives (HDDs) – For HDDs, the disk classification describes its spindle speed and can be any of three disk types. • • 7K (RPM) • 10K (RPM) • 15K (RPM) Solid State Drives (SSDs) – SSDs are differentiated by read or write optimization.
Low Space Modes A Storage Center enters Conservation mode when free space becomes critically low, and enters Emergency mode when the system can no longer write to the disks because there is not enough free space. Prior to entering Conservation mode, the Storage Center displays alerts indicating that disk space is running low. The alert reflects the amount of space left, beginning with 10%, before the system stops operating. The alert updates each time the remaining space decreases by 1%.
• • • • • Change the storage profile to a more space-efficient profile. Available profiles might include Low Priority (Tier 3) and Maximize Efficiency. Configure a threshold definition to create an alert when space starts to get low. Migrate volumes from a pagepool with a full tier to a different pagepool with more free space. Delete unnecessary volumes. If Data Reduction is licensed, enable Compression or Deduplication with Compression on some volumes.
Low Priority (Tier 3) The Low Priority profile provides the most cost efficient storage. Creating a volume using the Low Priority profile stores written data on Tier 3 RAID 10. Snapshot data is stored on Tier 3 RAID 5/6. Storage Center does not migrate data to higher tiers of storage unless Tier 3 storage becomes full. Storage Profiles for Flash-Optimized Storage The table below summarizes storage profiles available for flash-optimized storage types.
Storage Virtualization for SCv2000 Series Controllers SCv2000 series controllers manage many storage virtualization options automatically. Disk Management on SCv2000 Series Controllers Storage Centers with SCv2000 series controllers manage disks automatically, limiting the disk management options. After adding disks, Storage Center recognizes the new disks, creates a new disk folder if necessary, then manages the disks in the disk folder.
User Interface for Storage Center Management The user interface varies depending on whether you connect directly to a Storage Center or connect through a Data Collector. Unisphere Views The following Unisphere views are displayed when you connect a web browser to a Storage Center. Summary View The Summary view is a dashboard that displays summarized information about the Storage Center. Figure 1.

Depending upon the protection model used in deployment, failure to use the external database could result in the loss of some or all VVols metadata when the Data Collector is uninstalled or deleted.
• vSphere recognizes them as protocol endpoints after the VASA provider is registered and a Storage Container is created using Unisphere Central. Storage container — A storage container is a quantity of storage made available for the placement of virtual volumes-based VMs. Each array has at least one storage container. Each storage container has one or more protocol endpoints associated with it. NOTE: Storage containers are not supported outside of the virtual volumes context.
VASA Provider Restrictions The following restrictions apply to the VASA provider: • • • The Unisphere Central VASA provider can be registered to only one vCenter Server. All ESXi and vCenter Server requests to the VASA provider are mapped to a single Unisphere Central user. The VASA provider does not support user-defined storage profiles. Only default system-defined storage profiles can be used in VM Storage Policies.
Upgrade of Dell Unisphere Central Dell Unisphere Central In Dell Unisphere Central, certificates are based on IP addresses. After an upgrade to Dell Unisphere Central, the existing certificates remain unchanged. If you need to modify the IP address of the host, the certificates would need to be updated, as described in the following table.
How Storage Container Options Affect vCenter Advertised Capabilities The creation of a storage container includes specifying options such as the use of compression, deduplication, encryption, and snapshots and Storage Center Storage Profiles. When the storage container creation completes. these options are advertised as capabilities to vCenter. The following VASA version 2.
NOTE: When modifying VM storage policies especially for compression and deduplication, apply the VMware administrator policies to all volumes associated with VM. If these same changes are not applied to all volumes, some portion of the VM could be compressed while other portions could be uncompressed. NOTE: The advertised capabilities only apply to VVols datastores and are not supported on legacy VMFS datastores.
Old VM Storage Policy New VM Storage Policy Expected Behavior Deduplication Disabled Deduplication Enabled Data Reduction Profile of associated VVols changes to Deduplication with Compression. Data is deduplicated at the next data progression cycle. Deduplication Enabled Deduplication Disabled Data Reduction Profile of associated VVols changes from Deduplication with Compression to None.
