Abstract: A storage enclosure includes a plurality of hard drive sub-boards, each configured to include a plurality of hard drives. Each hard drive sub-board is coupled to one or more expanders, via and interface unit, with a set of dual-pass shielded cables. The expander includes a plurality of chipsets coupled to a complex logic device. Each chipset may communicate with a different subset of hard drives with potentially different timing characteristics. The dual-pass shielded cables may be arranged to mitigate these differences. In addition, pin assignments associated with the cables may be set in order to further mitigate the timing differences.

Abstract: A storage enclosure includes a plurality of hard drives coupled to a logic device that, in turn communicates with an operating system (OS) executing on a host computer system. When the storage enclosure is powered on, the hard drives become active at different times and transmit activation reports to the logic device in a random order. The logic device receives these activation reports, and then reorders then to align with the bay numbers where the hard drives are mounted. The logic device then transmits the reordered activation reports, and the OS assigns logical IDs to the hard drives that match the bay numbers.
