Multi-drive hot plug drive carrier
First Claim
1. Apparatus for a storage system, the storage system being capable of including multiple enclosures containing disk drives, the apparatus comprising:
- a disk drive carrier for containing two disk drives, the disk drive carrier being mountable within an enclosure in the storage system, the disk drives being Fibre Channel compatible, wherein the disk drives are oriented such that the sides of the disk drives on which fibre channel connectors are disposed face each other,wherein the disk drives are connected to a medium via flex circuits, and wherein the flex circuits are identical prior to use, and wherein the flex circuits are pre-configured into different shapes based upon the positions of the fibre channel connectors to connect the drives to a common medium,wherein the flex circuits contain a signal layer and a ground layer,wherein a first flex circuit is connected such that its signal layer lies adjacent to an HDA cover plate on a disk drive, andwherein a second flex circuit is connected such that its signal layer lies adjacent to the ground layer on the first flex circuit so that all signal layers are surrounded by ground layers.

Abstract
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.
