| ExtentStripeLength | uint16 | |
| Description | string | ExtentStripeLength describes the number of underlying StorageExtents across which data is striped in the common striping-based storage organizations. This is also known as the number of 'members' or 'columns'. When used in a goal setting instance, ExtentStripeLength is the optimal desired value. The bounds (max and min) for Stripe Length are defined using the properties ExtentStripeLengthMax and ExtentStripeLengthMin. ExtentStripeLength MUST be set to NULL if the scoping StorageCapablities indicates that it is not supported in this context. ExtentStripeLength can be used in conjunction with CreateOrModifyElementFromELements to explicitly configure storage. An example would be RAID 0+1 with mirroring two stripe sets, each set being three wide. In this case CreateOrModifyElementFromElements would be passed a goal setting with DataRedundancy = 2 and ExtentStripeLength = 3. The size of the InElements array would be 6 and would contain the StorageExtents to be used to construct the StorageElement as a RAID 0+1. ExtentStripeLengthMin and ExtentStripeLengthMax are meaningless and wouldbe set to NULL. If the property is supported, and is part of StorageSettingWithHints it MAY be set to NULL. If used it will constrain the effects of Hint selections. When used in a Setting instance associated to a Volume, this property indicates the specific value that the Volume was created with, and ExtentStripeLengthMin and ExtentStripeLengthMax will be set to the same specific value. |
