Publication number: 20160154597Abstract: Approaches for automatically backing up data from volatile memory to persistent storage in the event of a power outage, blackout or other such failure are described. The approaches can be implemented on a computing device that includes a motherboard, central processing unit (CPU) a main power source, volatile memory (e.g., random access memory (RAM)), an alternate power source and circuitry (e.g., a specialized application-specific integrated circuit (ASIC)) for performing the backup of volatile memory to a persistent storage device. In the event of a power failure of the main power source, the alternate power source is configured to supply power to the specialized ASIC for backing up the data in the volatile memory. For example, when power failure is detected, the ASIC can read the data from the DIMM socket using power supplied from the alternate power source and write that data to a persistent storage device.Type: ApplicationFiled: February 1, 2016Publication date: June 2, 2016Inventors: Samuel James McKelvie, Michael David Marr

Patent number: 9323577Abstract: 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.Type: GrantFiled: September 20, 2012Date of Patent: April 26, 2016Assignee: Amazon Technologies, Inc.Inventors: Michael David Marr, Matthew D.

Publication number: 20160087915Abstract: Host machines and other devices performing synchronized operations can be dispersed across multiple racks in a data center to provide additional buffer capacity and to reduce the likelihood of congestion. The level of dispersion can depend on factors such as the level of oversubscription, as it can be undesirable in a highly connected network to push excessive host traffic into the aggregation fabric. As oversubscription levels increase, the amount of dispersion can he reduced and two or more host machines can be clustered on a given rack, or otherwise connected through the same edge switch. By clustering a portion of the machines, some of the host traffic can he redirected by the respective edge switch without entering the aggregation fabric. When provisioning hosts for a customer, application, or synchronized operation, for example, the levels of clustering and dispersion can be balanced to minimize the likelihood for congestion throughout the network.Type: ApplicationFiled: December 7, 2015Publication date: March 24, 2016Inventors: Michael David MARR, Tyson J.
