Server systems having segregated power circuits for high availability applications

摘要

According to one embodiment, a server system includes a motherboard partition that includes a motherboard and at least one processor coupled to the motherboard, with each processor being coupled to a memory. The server system also includes a storage partition that includes the memory, and a power circuit being capable of supplying current to the motherboard partition and the storage partition independently, the power circuit including at least two redundant power supplies in parallel in the power circuit, with each redundant power supply being capable of providing an amount of current necessary to operate the server system, and the motherboard partition is adapted to run a server OS. In another embodiment, an active cluster system may include two server systems, with the motherboard partition from each server system being capable of communicating with the other server system's storage partition even if power is removed from the other system's motherboard partition.

主权项

1. A server system, comprising:
a motherboard partition comprising:
a motherboard, andat least one processor coupled to the motherboard, each processor being coupled to a memory; a storage partition comprising the memory; a power circuit being capable of supplying current to the motherboard partition and the storage partition independently, the power circuit comprising:
at least two redundant power supplies in parallel in the power circuit, each redundant power supply being capable of providing an amount of current necessary to operate the server system,an interface configured to connect the motherboard partition to a storage partition of a second server system via an external connection extending between the server system and the second server system, the second server system being external to the server system and powered separately therefrom; a first power switch positioned between the at least two redundant power supplies and the storage partition, wherein the first power switch is independently operable to selectively sever the power circuit to the storage partition, and a second power switch positioned between the at least two redundant power supplies and the motherboard partition, wherein the second power switch is selectively operable to sever the power circuit to the motherboard partition without severing power to the storage partition, wherein the motherboard partition is adapted to run a server operating system (OS).
