Abstract: A computer program product and computer implemented method are provided for migrating a virtual machine between servers. The virtual machine is initially operated on a first server, wherein the first server accesses the virtual machine image over a network at a memory location within fabric attached memory. The virtual machine is migrated from the first server to a second server by flushing data to the virtual machine image from cache memory associated with the virtual machine on the first server and providing the state and memory location of the virtual machine to the second server. The virtual machine may then operate on the second server, wherein the second server accesses the virtual machine image over the network at the same memory location within the fabric attached memory without copying the virtual machine image.

Abstract: Method and apparatus providing airflow through a chassis including an upstream column of memory modules and a downstream column of memory modules. The airflow is divided into first and second separate airflow streams extending from an upstream end of the upstream column to a downstream end of the downstream column. The first airflow stream is guided into contact with a single memory module operably-installed in the upstream column and to avoid contact with any memory module in the downstream column. The second airflow stream is guided to avoid contact with any memory module in the upstream column and into contact with a single memory module operably-installed in the downstream column. The improved cooling enables the extended use of a single memory module per channel, even though the thermal load on such a memory module is greater.

Abstract: Memory downsizing in a computer memory subsystem, the subsystem including one or more channels of computer memory with each channel including several Dual In-line Memory Modules (‘DIMMs’) and each DIMM capable of on-die termination (‘ODT’). Memory downsizing according to embodiments of the present invention includes identifying, during a memory initialization test in a Power On Self Test (‘POST’) by a firmware module, a defective DIMM of a particular channel in the computer memory subsystem and disabling, by the firmware module, the defective DIMM, including enabling ODT for the defective DIMM without disabling any non-defective DIMMs.

Abstract: Interrupts are directed to currently idle processors. Which of a number of processors of a computing system that are currently idle is determined. An interrupt is received and directed to one of the currently idle processors for processing. Determining which processors are currently idle can be accomplished by monitoring each processor to determine whether it has entered an idle state. When a processor has entered an idle state, it is thus determined that the processor is currently idle. Where just one processor is currently idle, an interrupt is directed to this processor. Where more than one processor is currently idle, one of these processors is selected to which to deliver an interrupt, such as in a round-robin manner. Where no processor is currently idle, then one of the processors is selected to which to deliver an interrupt.
