Now a Logical Unit (LUN) will be created using the SMI-S Provider. Release 1 of the SMI-S Provider supports the Provisioning and Capacity management SNIA SMI Profiles. For a full list of SMI-S profiles from SNIA, click here.

On the toolbar, click Create Logical Unit, which displays a dialog box to enter the LUN settings.

  • In the following example, a LUN named DEMO-LUN is created and assigned a description with a Size of 750GB. Now select Create thin storage logical unit with capacity committed on demand. Click OK to create the new LUN.
Note:

Selecting the Create thin storage logical unit with capacity committed on demand option is a best practice used in conjunction with the Everpure FlashArray.

Microsoft Hyper-V has the ability to use thinly provisioned storage. Reduce is one of the core features of Purity//FA. When creating a new Virtual Hard Disk (VHD/X), a small file is created, even if, for example, the Size property to 750 GB. The VHD/X does not consume any storage space on the FlashArray until data (Eg. install and operating system, add files) is written to the VHD/X.

The following example shows a new VHD, New Virtual Hard Disk that was set for 750 GB but only takes up 1.47 MB.

  • Once the LUN is created, it displays in the Classification and Pools node of the parent Storage node.

  • Using the FlashArray Web management interface the DEMO-LUN can be seen using the all Volumes view with zero space.
