Operating profiles for consumers of computing resources may be automatically determined based on an analysis of actual resource usage measurements and other operating metrics. Measurements may be taken while a consumer, such as a virtual machine instance, uses computing resources, such as those provided by a host. A profile may be dynamically determined based on those measurements. Profiles may be generalized such that groups of consumers with similar usage profiles are associated with a single profile. Assignment decisions may be made based on the profiles, and computing resources may be reallocated or oversubscribed if the profiles indicate that the consumers are unlikely to fully utilize the resources reserved for them. Oversubscribed resources may be monitored, and consumers may be transferred to different resource providers if contention for resources is too high.

The disclosure provides an HVAC data processing and communication network and a method of manufacturing the same. In one embodiment, the HVAC data processing and communication network includes a system device, a subnet controller and a user interface. The system device is configured to receive a control message from a data bus and operate according to a control setting communicated thereby. The system device is further configured to generate an alarm message in the event that the device enters an alarm state in response to an alarm condition. The user interface is configured to receive the alarm message and display alarm information in response to the message. The subnet controller is configured to provide operational control of the system device via the control message. The operational control is decoupled from the alarm message.

Disclosed herein is a controller architecture that pairs a controller with a NVM (non-volatile memory) storage system over a high-level, high speed interface such as PCIe. In one embodiment, the NVM storage system includes a bridge that communicates with the controller via the high-level interface, and controls the NVM via an interface (e.g., ONFI). The controller is provided a rich set of physical level of controls over individual elements of the NVM. In one embodiment, the controller is implemented in a higher powered processor that supports advanced functions such as mapping, garbage collection, wear leveling, etc. In one embodiment, the bridge is implemented in a lower powered processor and performs basic signal processing, channel management, basic error correction functions, etc. This labor division provides the controller physical control of the NVM over a fast, high-level interface, resulting in the controller managing the NVM at both the page and block level.

A write-caching RAID controller includes a CPU that manages transfers of posted-write data from host computers to a volatile memory and transfers of the posted-write data from the volatile memory to a redundant array of storage devices when a main power source is supplying power to the RAID controller. A memory controller transfers the posted-write data received from the host computers to the volatile memory and transfers the posted-write data from the volatile memory for transfer to the redundant array of storage devices as managed by the CPU. The memory controller flushes the posted-write data from the volatile memory to the non-volatile memory when main power fails, during which time capacitors provide power to the memory controller, volatile memory, and non-volatile memory, but not to the CPU, in order to reduce the energy storage requirements of the capacitors. During main power provision, the CPU programs the memory controller with information needed to perform the flush operation, such as the location and size of the posted-write data in the volatile memory and various flush operation characteristics.

A RAID controller performs a preemptive reconstruct of a redundant array of disks while it is still fault-tolerant by determining the errors by a first disk exceeded the error threshold, and reading data from a second disk, and writing the data to a spare disk. The second disk's data is a mirrored copy of the first disk's data. The controller also replaces the first disk with the spare disk, after completing the reading and writing. Additionally, while performing the reading and writing, the controller writes second data to the first disk in response to a user write request including the second data, thereby maintaining the fault-tolerance of the redundant array. In another embodiment, the controller creates the data of the first disk from second data read from two or more of the other disks in the array and writes the created data to the spare disk.

An arrangement and methods for operation in a cache memory system to facitate re-synchronising non-volatile cache memories (150B, 160B) following interruption in communication. A primary adapter (150) creates a non-volatile record (150C) of each cache update before it is applied to either cache. Each such record is cleared when the primary adapter knows that the cache update has been applied to both adapters' caches. In the event of a reset or other failure, the primary adapter can read the non-volatile list of transfers which were ongoing. For each entry in this list, the primary adapter negotiates with the secondary adapter (160) and transfers only the data which may be different. The amount of data to be transferred between the adapters following reset/failure is generally much lower than under previous solutions, since the data to be transferred represents only the transactions which were in progress at the time of the reset or failure, rather than the entire non-volatile cache contents; also, new transactions need not be suspended while even this reduced resynchronisation takes place: all that is necessary is for the (relatively short) list of in-doubt quanta of data to be searched (if the transaction does not overlap any entries in this list then it need not be suspended; if it does overlap then the transaction may be queued until the resynchronisation completes).

A redundant storage controller system that robustly provides failure analysis information (FAI) to an operator of the system is disclosed. The system includes first and second storage controllers in communication with one another, such as via a PCI-Express link. When one of the controllers fails, the FAI is transferred from the failed controller to the surviving controller over the link. The operator issues a command to the surviving storage controller, which responsively provides the FAI. In one embodiment, the failed storage controller writes the FAI to the second storage controller. In one embodiment, each storage controller periodically writes the FAI before there is a failure. In one embodiment, the second storage controller reads the FAI from the failed storage controller. The FAI may include boot logs, crash logs, debug logs, and event logs. The FAI may also be written to a disk drive connected to the controllers.

Redundant storage controller system with enhanced failure analysis capability

A bus bridge on a primary RAID controller receives user write data from a host and writes the data to its write cache and also broadcasts the data over a high speed link (e.g., PCI-Express) to a secondary RAID controller's bus bridge, which writes the data to its mirroring write cache. However, before writing the data, the second bus bridge automatically invalidates the cache buffers to which the data is to be written, which alleviates the primary controller's CPU from sending a message to the secondary controller's CPU to instruct it to invalidate the cache buffers. The secondary controller CPU programs its bus bridge at boot time with the base address of its mirrored write cache to enable it to detect that the cache buffer needs invalidating in response to the broadcast write, and with the base address of its directory that includes the cache buffer valid bits.
