Disclosed are ways of providing a highly flexible high availability storage system. Disk drive carriers for insertion into enclosures in a storage system include several disk drives. The enclosures accept carriers that include drives of different sizes, and drives compatible with different storage technologies, for instance Fibre Channel, SATA, or SAS. Drives oriented in their carriers in a manner that allows them to be connected to a common medium via identical flex circuits that are configured based on the orientation of the drives. Redundant controllers include redundant serial buses for transferring management information to the carriers. The carriers include a controller for monitoring the multiple serial buses and producing storage technology specific management commands for the disk drives.

摘要:
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.
摘要:
A midplane has plated through holes (PTHs) which form a first profile and a second profile. The first profile has (i) an overlapping portion which overlaps at least part of the second profile and (ii) a non-overlapping portion which does not overlap any part of the second profile. A first connector mounts to a first side of the midplane over the first profile, and a second connector mounts to a second side of the midplane over the second profile. At least one PTH is a shared PTH which resides in both the first and second profiles and which engages a pin of the first connector and a pin of the second connector. Additionally, at least one PTH is a non-shared PTH which resides in the non-overlapping portion of the first profile and which engages a pin of the first connector without engaging any pins of the second connector.

A computer system for managing a computer network comprises a rack cabinet having a cabinet interior. A plurality of infrastructure connector assemblies are fixedly mounted on the rack cabinet in 1-U boundaries, each infrastructure connector assembly including a signal snap interface connector and a power snap interface connector. A plurality of compute elements are adapted to be slidably disposed within the cabinet interior of the rack cabinet in a stacked relationship, each compute element including at least one infrastructure connector assembly which releasably snap-interconnects with an associated infrastructure connector assembly mounted on the rack cabinet. A distributed power bay is disposed within the rack cabinet and provides central power for the computer system. A rack manager is disposed within the rack cabinet and includes the central video and I/O devices for the computer system. A cabinet controller is disposed within the rack cabinet and is responsible for the management of a geography bus and an intelligent chassis management bus for the computer system.

A connection assembly has a midplane, first midplane connectors and second midplane connectors. The midplane is divided into an airflow section and a connector section by a dividing line. The midplane defines a first side and a second side which faces away from the first side. The airflow section provides airflow passageways connecting spaces on both sides of the midplane. The connector section provides (i) first mounting locations which are confined to the connector section on the first side and (ii) second mounting locations which are confined to the connector section on the second side. The first midplane connectors are arranged to connect to first circuit board modules, and are mounted over the first mounting locations on the first side. The set of second midplane connectors are arranged to connect to second circuit board modules, and are mounted over the second mounting locations on the second side.

An improved redundant computing apparatus has a chassis assembly configured to (i) mount to a standard electronic equipment rack and (ii) consume substantially 1U of space in a particular direction within the standard electronic equipment rack. The chassis assembly includes a housing and a midplane disposed within the housing. The apparatus further includes a set of power supply/blower assemblies configured to electrically connect to and electrically disconnect from the midplane of the chassis assembly in a hot swappable manner, and a set of computing devices configured to electrically connect to and electrically disconnect from the midplane of the chassis assembly in a hot swappable manner. By way of example, the set of computing devices is adapted to move data into and out of a set of disk drives on behalf of a set of external host computers.

An expandable memory system and a method for operating a memory system having a variable number of memory banks are described. The memory system can utilize a variable number of separately replaceable memory banks which can be implemented with memory element, such as dynamic random access memory chips, which are of differing speeds and or sizes. The memory system implements an interleaving of memory addresses among the memory banks as a function of the number of banks actually present so that successive memory accesses are not unnecessarily delayed by the recovery times of the memory elements. The memory system includes a programmable address decoder having a writable memory which provides bank address signals. Each of the banks includes a respective delay line for providing an output signal a respective presettable time after address signals are received by that bank for signalling to the host that data is ready to be transferred.
摘要:
Described is a midplane-less storage system comprising an enclosure including a control board having an electrical connector attached thereto and a processing unit. The enclosure also includes a disk drive module with a disk drive for storing data and an adapter board electrically connected to the disk drive. The adapter board has a controller and an electrical connector that is mated to the electrical connector of the control board. A communication bus extends from the control board to the disk drive module through the mated electrical connectors. The processing unit of the control board communicates with the controller of the adapter board over the communication bus in accordance with a communication protocol in order to control operation of the disk drive.
