Managed Application
Licenses (MALs) Managed application licenses (MALs) are the number of detected instances of Microsoft Exchange, Oracle and Sybase Adaptive Server Enterprise.
managed object | A hardware or software system component that is represented as an instance of the |
| CIM class. Information about managed objects is supplied by data and event |
| providers, as well as by the CIM Object Manager. |
Managed Access | Manage access points (MAPs) are the sum of all storage access ports of all hardware |
Points (MAPs) | |
| elements that the management server manages. |
materialized view | A materialized view is a snapshot of data, from the database, created from a query. |
mapped | Mapped is capacity that is accessible by one or more hosts external to the array |
| (aggregated capacity of volumes that are accessible from hosts external to the |
| subsystem). |
meta device | This term is used by EMC. A meta device is a device that is a concatenation of several |
| devices. |
metavolume | Metavolumes are created from a disk, slice, stripe, or other metavolumes. Metavolumes |
| are extremely useful because they can expand their storage capacity, such as to |
| mainframe volume sizes. Also referred to “LDEVs” for HDS storage systems. |
missing element | The management server was able to discover the element, but it lost contact with the |
| element before more information could be gathered during “Get the Topology” or |
| Discovery Data Collection/Get Details. A missing element can be managed if the |
| management server lost contact with the element after Discovery Data Collection/Get |
| Details was performed. |
multipathing | The process of providing a server more than one path to a storage system. So that in |
| the case of an emergency, the server will have continuous access to the storage system. |
| Multipathing can be done many ways. For example, you can provide redundant |
| switches for a server to access a storage system. Another example of multipathing is |
| providing redundant paths from the server to the switch. |

provider | A provider is software that is used to gather information about an element. |
proxy server | A device, such as a host, connected to a storage system. It is sometimes referred to as |
| a storage system proxy or an API proxy. An example of a proxy server is the EMC |
