Abstract
Described are a system and method of detecting an improperly connected cable in a storage system. A system includes an enclosure having boards. Each board of the enclosure has a communications port that receives a message identifying a redundant backend network to which that board is connected. The enclosure determines whether the system has an improper cable connection by determining from the messages whether the boards are connected to the same redundant backend network.
Claims20
A system, comprising:
- an enclosure having boards, each board having a communications port that receives a message identifying a redundant backend network to which that board is connected, the enclosure determining whether the system has an improper cable connection by determining from the messages whether the boards are connected to the same redundant backend network.
An enclosure for a system, comprising:
- a first and a second card, each card having a communications port;
- a first cable conveying an identifier to the communications port of the first card, and a second cable conveying an identifier to the communications port of second card, each identifier identifying a network to which the card receiving that identifier is connected;
- and
- means for determining if the cards are connected to different networks based on the identifiers conveyed to the communications ports of the first and second cards.
A method of testing connectivity of cabling in a storage system implementing redundancy, the method comprising:
- receiving at a first card in an enclosure a first identifier over a first cable;
- receiving at a second card in the enclosure a second identifier over a second cable;
- and
- determining if the cards are connected to different networks based on the first and second identifiers.
