Views

The SOM package contains views that display common storage topologies. These are basic views that can be customized to suit the integrated SOM applications.

Storage Array Details

This view shows a Storage Array and its components including Logical Volumes, HBAs, Storage Processors, and Fibre Channel Ports. The view shows each component under its container Storage Array and groups Logical Volumes by CI Type.

Storage Array does not require all components in this view to be functional. Composition links stemming from the Storage Array have a cardinality of zero-to-many. The view may show Storage Arrays even when there are no Logical Volumes or Storage Processors.

FC Switch Details

This view shows a Fibre Channel Switch and all connected Fibre Channel Ports.

FC Switch Virtualization

FC Switch Virtualization consists of a physical switch or chassis, partitioned into multiple logical switches. Unlike Ethernet virtualization, physical ports are not shared among multiple virtual switches. Rather, each virtual switch is assigned one or more dedicated physical ports that are managed independently by the logical switches.

Storage Pool Details

This view shows Storage Pools with associated Storage Arrays and Logical Volumes.

Host Storage Details

This view shows only Hosts that contain a Fibre Channel HBA or a Logical Volume. This keeps the view storage-specific and prevents hosts discovered by other DFM jobs from being included in the view.

SAN External Storage

External storage configuration consists of a storage array presenting a logical volume that, in reality, belongs to another storage array. This is typically used in configurations where high-end, more expensive, front-end arrays present volumes from back-end, cheaper, storage to servers. The goal of this type of virtualization is to virtualize multiple disk arrays from different vendors, scattered over the network, into a single monolithic storage device that can be managed uniformly.

SAN Topology

This view maps physical connections between Storage Arrays, Fibre Channel Switches, and Hosts. The view shows Fibre Channel Ports below their containers. The view groups the Fibre Channel Connect relationship CIT to prevent multiple relationships between the same nodes from appearing in the top layer.

Note A node can be a physical host or an inferred host.

Storage Topology

This view maps logical dependencies between Logical Volumes on Hosts and Logical Volumes on Storage Arrays. There is no folding in this view.
