Disk (dictionary item)
For automation interface information about a Disk, see Disk (automation interface).
A disk is a mass storage device attached to the system.
The Speed and Size of a Disk is specified by a linked Disk Type.
You can create a Disk through the context menu of a Package: right-click the Package, and select New > Proprietary > System Architecture Model > Disk.
In addition, you can also create a Disk by copying an existing Disk. Modeler copies the Disk's links. For more information, see Copying items.
When used on a System Architecture Diagram, a Disk's notation is as follows:
If a Disk has two or more instances, the following notation is used.
In the Modeler panes, a short-cut symbol on the Disk's icon indicates that the item is a stub.
The following sections provide information about how a Disk is used in the model. For more information about a property, item, model part or diagram, click it.

In addition to the standard properties, a Disk has these properties:
* 
• The Disk Type list on the Options tab of a Disk's Property Pages allows you to link the Disk with a Disk Type.
• The Size and Speed properties that are displayed on the Options tab of a Disk's Property Pages are inherited from the linked Disk Type.

Point-to-point Connection — The Point-to-point Connection is owned jointly by the Disk and the associated item. The access permissions you have to a Point to Point Connection are determined by the access permissions you have to the source item.
