The implementation of Kinetic drives with the network attached ethernet interface eliminates the need for Storage Servers in data centers, thus can be removed from the storage rack configuration. The removal of the Storage Servers allows an increase in storage density per rack by providing more rack units to be populated with HDD. An example configuration for a standard 42U rack is shown below for Conventional drives and Kinetic drives, where JBOD represents "Just a Bunch Of Disks" and JBOK represents "Just a Bunch Of Kinetics". Both configurations requires a 1U Top of Rack Switch, but for the Conventional drives, the configuration requires a Rack Server and Management Switch, using 1U of rack space each. In this specific Conventional Drive Configuration, each Storage Server handles up to 15 HDD. The calculations were made with the assumption that there are 60 HDD stored for every 4U (15 HDD per U).
This example configuration shows a significant increase of 420 HDD per storage rack with the implementation of Kinetic drives and elimination of Storage Servers. Since each Kinetic drive holds 4TB, each rack will have a storage density increase of 1680 TB for this example. There are many other variances of hardware configurations for the rack of Conventional drives, but all will have a storage density increase with the elimination of Storage Servers.
