 First Generation Kinetic HDD

The first Kinetic drive is a 4 TB, 5900 rpm, 3.5" hard disk drive (HDD).

Compared to its conventional sister drive, the Kinetic drive implements the Kinetic API that enables key-value object storage. The Kinetic drive replaces the Serial Advance Technology Attachment (SATA) or Serial Attached SCSI (SAS) interface connections with the two 1-Gbps SGMII Ethernet ports, which enables direct network attached connectivity. The Ethernet interface allows communication between drives and direct communication to the datacenter, eliminating the need for Storage Servers for datacenter storage racks.

Drive Form Factor

The mechanical dimensions for the HDD are shown below. Kinetic chassis conform to this standard drive form factor.

Kinetic Connector

Connector Mechanical

Kinetic drives repurposes the standard SAS HDD connector. The connector is defined by and conforms to the dimensions and specifications of SFF-8482 Rev 2.3 [ftp link]. Its placement in the drive form factor is identical to SAS drives.

 

 

Connector Pin Assigments

Two 1-Gbps SGMII Ethernet interfaces are provided through pins S2/S3-S5/S6 and S9/S10-S12/S13, respectively, repurposing the SAS primary and secondary port signals. All drive power signal assignments, shown in the table below, are identical to the standard SAS drive connector (plug) as outlined in SFF-8482.
