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.
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.
