20120233117 | Higher Efficiency Storage Replication Using Compression - An improved scalable object storage system includes methods and systems allowing multiple clusters to work together. In one embodiment, there is a multi-cluster synchronization system between two or more clusters. The multi-cluster synchronization system uses variable compression to optimize the transfer of information between the clusters. Compression is used not only to minimize the total number of bytes sent between the two clusters, but to dynamically vary the size of the objects sent across the wire to optimize for higher throughput after considering packet loss, TCP windows, and block sizes. This includes both the packaging of multiple small files together into one larger compressed file, saving on TCP and header overhead, but also the chunking of large files into multiple smaller files that are less likely to have difficulties due to intermittent network congestion or errors. | 09-13-2012 |
20120233118 | Multi-Cluster Container Replication - An improved scalable object storage system allows multiple clusters to work together. In one embodiment, a multi-cluster synchronization system synchronizes data between two or more clusters. Each cluster has a cluster-internal network, with object storage services and container services. The container services track and replicate metadata associated with the object storage service. An intercluster network connects the two clusters and performs a one-way synchronization of the objects and metadata associated with a particular container. In a further embodiment, multiple synchronization relationships can be set up, either in a cycle (with two or more participants), in a line, or in a tree. For example, the multi-cluster replication could be used to transparently synchronize objects in a CDN network. | 09-13-2012 |
20120233251 | Virtual Multi-Cluster Clouds - An improved scalable object storage system allows multiple clusters to work together. Users working with a first cluster, or with a multi-cluster gateway, can ask for services and have the request or data transparently proxied to a second cluster. This gives transparent cross-cluster replication, as well as multi-cluster compute or storage farms based upon spot availability or various provisioning policies. Vendors providing a cloud storage “frontend” can provide multiple backends simultaneously. In one embodiment, a multi-cluster gateway can have a two, three, or higher-level ring that transparently matches an incoming request with the correct cluster. In the ring, a request is first mapped to an abstract “partition” based on a consistent hash function, and then one or more constrained mappings map the partition number to an actual resource. In another embodiment, the multi-cluster gateway is a dumb gateway, and the rings are located only at the cluster level. | 09-13-2012 |
20120233463 | Cluster Federation and Trust - An improved scalable object storage system allows multiple clusters to work together. In one embodiment, a trust and federation relationship is established between a first cluster and a second cluster. This is done by designating a first cluster as a trust root. The trust root receives contact from another cluster, and the two clusters exchange cryptographic credentials. The two clusters mutually authenticate each other based upon the credentials, and optionally relative to a third information service, and establish a service connection. Services from the remote cluster are registered as being available to the cluster designated as the trust root. Multi-cluster gateways can also be designated as the trust root, and joined clusters can be mutually untrusting. Two one-way trust and federation relationships can be set up to form a trusted bidirectional channel. | 09-13-2012 |

20130032354 | ANNULAR PRESSURE REGULATING DIAPHRAGM AND METHODS OF USING SAME - Downhole tools comprise a housing chamber with an expandable member disposed therein. An interior of the expandable member is in fluid communication with an outside environment so that hydrostatic pressure can act on an inner wall surface of the expandable member. The outer wall surface of the expandable member partially defines a sealed chamber within the housing chamber such that expansion of the expandable member due to an increase in hydrostatic pressure causes the volume within the sealed chamber to decrease, thereby energizing the sealed chamber. Thus, an increase in hydrostatic pressure within an outside environment is compensated. Further, when the hydrostatic pressure within the outside environment decreases, the energized sealed chamber causes contraction of the expandable member, thereby compensating for the decrease in hydrostatic pressure. | 02-07-2013 |
