Midplane-independent implementations of data storage system enclosures
First Claim
1. A storage system comprising:
- a control board having an electrical connector attached thereto;
a disk drive module having a disk drive for storing data and an adapter board electrically connected to the disk drive, the adapter board having an electrical connector attached thereto;
a midplane having a first connector connected to the electrical connector of the control board and a second connector connected to the electrical connector of the adapter board, the first and second connectors of the midplane being attached to opposite sides of the midplane in alignment with and electrically connected to each other through the midplane such that an electrical signal transmitted between the control board and the adapter board passes directly through the midplane through the first and second connectors.

Abstract
Described is a storage system comprising a communication bus, a disk drive, a control board having a processing unit connected to the communication bus, and an adapter board in electrical communication with the disk drive. The adapter board has a controller connected to the communication bus. The controller receives instructions over the communication bus from the processing unit and communicates with the disk drive in response to the instructions. Optionally, the storage system has a midplane having a first connector connected to an electrical connector of the control board and a second connector connected to an electrical connector of the adapter board. Attached to opposite sides of the midplane, the first and second connectors are aligned with and electrically connected to each other through the midplane. An electrical signal transmitted between the control board and the adapter board passes directly through the midplane through the first and second midplane connectors.

17. A method of verifying loop identification and address information sent to first and second control boards of an enclosure over a Fibre Channel loop, the method comprising
storing the information received by the first control board in a first register and the information received by the second control board in a second register; -
sending by the first control board a command over a communication bus to the second register to read the information stored therein;
comparing by the first control board the information read from the second register with the information stored in the first register to determine if the first and second control boards received the same information over the Fibre Channel loop. - View Dependent Claims (18, 19, 20)
