    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

    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
