710 74, 710 1, 710 46, 710 65, 710100
Abstract:

A controller is provided that receives a single enclosure management (EM) serial bit stream from an expander or other device and divides the EM serial bit stream into multiple EM serial bit streams for delivery to multiple respective midplanes or backplanes. In this way, a separate EM serial bit stream is provided to each midplane or backplane without having to increase the number of ports that are available on the expander or other device that interfaces with the backplane or midplane.

US Patent:

20030115387, Jun 19, 2003
Filed:

Dec 17, 2001
Appl. No.:

10/023101
Inventors:

Jeremy Stover - Wichita KS, US
Jason Stuhlsatz - Wichita KS, US
International Classification:

G06F003/00
US Classification:

710/060000
Abstract:

A system has a plurality of enclosures. Each enclosure has two enclosure services modules. Each enclosure services module has an IN port and an EXPANSION port. Each enclosure services module is able to determine the data rate of incoming data and check the validity of this data. If the data rate is other than what the enclosure services module is set for, the data rate of the enclosure services module is changed to that of the incoming data. In the system, there are a disk array controller having a first channel and a second channel. The first channel is formed in sequence from a disk array controller to a first enclosure services module of a first enclosure and between first enclosure services modules of successive enclosures to a last enclosure. The second channel is formed in reverse sequence from the disk array controller to the second enclosure services module of the last enclosure and between second enclosure services modules of successive enclosures to the first enclosure.

US Patent:

20070217141, Sep 20, 2007
Filed:

Mar 16, 2006
Appl. No.:

11/377472
Inventors:

Mohamad El-Batal - Westminster CO, US
Greg Shogan - Round Rock TX, US
Jason Stuhlsatz - Wichita KS, US
International Classification:

G06F 1/16
US Classification:

361685000
Abstract:

A universal controller connector is modular, scalable and enables ease of connection between various storage devices (e.g., hard drives) and the same midplane controller. The universal controller connector solves the need for modularity and scalability for use with new storage controllers requiring midplane connections by managing connections between midplane controller and interface modules. The connection form factor enables universal connectivity of modules to a controller.

US Patent:

20110231674, Sep 22, 2011
Filed:

Dec 11, 2008
Appl. No.:

12/523509
Inventors:

Jason M. Stuhlsatz - Dacula GA, US
Mohamad El-Batal - Westminster CO, US
Keith Holt - Wichita KS, US
International Classification:

G06F 1/26
G06F 11/16
US Classification:

713300, 714 62, 714E11062
Abstract:

Disclosed is a storage system enclosure. A midplane receives, from a controller coupled to the midplane, a first drive status signal and a second drive status signal. The first drive status signal and the second drive status signal are associated with a storage device. The first drive status signal indicates a fault condition associated with the storage device. The second drive status signal indicates that an action is allowed on the storage device. A drive power control supplies or removes power from the storage device in response to the state of the first drive status signal and the second drive status signal.
