Scale Capacity by Adding Disk Shelves
Add capacity non-disruptively by adding external disk shelves
A disk shelf contains high capacity HDDs and a SSD
Add multiple disk shelves per Nimble Storage array
Add up to three shelves Only one shelf for the CS-210
Mix and match different capacity shelves

Adding a Shelf
1. Check to see if you have proper Nimble OS version2. Cable new expansion shelf and power on3. The new shelf is discovered by the control head
Newly discovered shelves will be shown as Available in the GUI/CLI4. Using the GUI or CLI, activate the new shelf

Scale Capacity Storage Pool
Storage pool grows when an expansion shelf is activated. Segment Layer is updated with new ending block data
The segment layer provides a map between the Nimble file system addresses and disk locations
The map is dynamically created for each incoming write request Essentially the segment layer works as a traffic cop by directing writes to the
proper disks
