Provided is a novel approach for connecting servers to peripherals, such as NICs, HBAs, and SAS/SATA controllers. Also provided are methods of arranging peripherals within one or more I/O directors, which are connected to the servers over an Ethernet network. Such arrangement allows sharing the same resource among multiple servers.

A system and method is provided to allow a computer network system to keep a device in a powered off state over a power cycle. A service processor stores the power state information or power mask corresponding to the field replaceable unit (FRU) slots in a non-volatile storage location. As a result, after the system has been powered off and on, the power mask information is retained. Accordingly, a hotswap controller may then retrieve the power mask from storage to determine whether a given FRU should be powered on or kept in a powered off state. Depending on the power mask, the service processor will not power on the FRU if the power mask indicates that the device should remain in a powered off state. A management entity may update the power mask information depending on predetermined parameters or the condition of the FRU. As a result, a power mask may be maintained for several power cycles to keep a device in a powered off state.

System and method for providing a persistent power mask

Provided is a method and an apparatus for allocating contiguous chunks of physical address space. Specifically, the contiguous chunks are homogenized by allocating kernel pages from kernel page free lists and user pages from a user page free list. The kernel page free lists are a nonrelocatable kernel page free list and relocatable kernel page free list. The user page free list has free pages that populate the relocatable kernel page free list. Each page that populates the relocatable kernel page free list includes an identifier such that the identifier permits the addition of the page to the relocatable kernel page free list. By providing three types of page free lists, satisfied requests for free pages from the page free lists create contiguous chunks of physical address space.
