Method And System For Consistent Cluster Operational Data In A Server Cluster Using A Quorum Of Replicas

View page
US Patent:
6938084, Aug 30, 2005
Filed:
Jul 2, 2001
Appl. No.:
09/895810
Inventors:
Rod Gamache - Seattle WA, US
Michael T. Massa - Seattle WA, US
Sunita Shrivastava - Redmond WA, US
Gor V. Nishanov - Redmond WA, US
David B. Lomet - Redmond WA, US
Philip A. Bernstein - Bellevue WA, US
Rohit Jain - Bellevue WA, US
Assignee:
Microsoft Corporation - Redmond WA
International Classification:
G06F015/173
US Classification:
709226, 709220, 709223
Abstract:
A method and system for increasing server cluster availability by requiring at a minimum only one node and a quorum replica set of replica members to form and operate a cluster. Replica members, independent from the nodes, maintain cluster operational data. A cluster operates when one node possesses a majority of replica members, which ensures that any new or surviving cluster includes consistent cluster operational data via at least one replica member from the immediately prior cluster. Arbitration provides exclusive ownership by one node of the replica members, including at cluster formation, and when the owning node fails. Arbitration uses a fast mutual exclusion algorithm and a reservation mechanism to challenge for and defend the exclusive reservation of each member. A quorum replica set algorithm brings members online and offline with data consistency, including updating unreconciled replica members, and ensures consistent read and update operations.

Distributed System Resource Protection Via Arbitration And Ownership

View page
US Patent:
7277952, Oct 2, 2007
Filed:
Sep 28, 2001
Appl. No.:
09/967350
Inventors:
Gor Nishanov - Redmond WA, US
Peter William Wieland - Seattle WA, US
Assignee:
Microsoft Corporation - Redmond WA
International Classification:
G06F 15/16
G06F 15/173
US Classification:
709229, 709213, 709217, 709223, 709226, 710240
Abstract:
In a distributed system, a resource such as a storage device is protected by an owner node's exclusive access to it, wherein exclusive access is established via a persistent reservation on the resource. A persistent reservation is never removed, however the owner node's persistent reservation may be challenged in an arbitration process, to take it away from a failed owner node. A challenger node challenges by changing an owner's access key (that establishes the persistent reservation) to a challenge key, delaying, and determining whether the owner restored the owner's access key during the delay, because a properly operating owner replaces a challenge key with its owner access key. If the owner fails to restore its owner access key, the challenger node becomes the new resource owner by replacing the challenge key with an owner access key of the challenger node. The key may include additional information to provide extensibility.

Serialization For Structured Tracing In Managed Code

US Patent:
7467374, Dec 16, 2008
Filed:
Nov 5, 2003
Appl. No.:
10/702258
Inventors:
Gor Nishanov - Redmond WA, US
Vitali Prokopenko - Bellevue WA, US
Assignee:
Microsoft Corporation - Redmond WA
International Classification:
G06F 9/44
US Classification:
717128, 717124, 717127, 717129
Abstract:
A system and method, useful in tracing program execution, for serializing data, such as an object data, into consistent, structured (e. g. , XML) output. A serializer processes an object's data, and for each set of data, records the object's data in a structured (e. g. , XML) format that reflects the object's current state. Nodes corresponding to fields and properties of the object are nested in the structure. Simple types define nodes with the current data value associated with the tag. More complex types including arrays, collections, dictionaries and exceptions are stored as individual members of a type, with any complex members further broken down into sub-nodes. Object data including custom collections, dictionaries, non-public fields and properties and properties with only get-accessor are serialized. The resulting output, such as in an XML formatted structure, is easy to read by humans, and is easily processed, such as for automated analysis purposes.

Cluster Shared Volumes

US Patent:
7840730, Nov 23, 2010
Filed:
Jun 27, 2008
Appl. No.:
12/147956
Inventors:
Andrea D'Amato - Kirkland WA, US
Rajeev Y. Nagar - Sammamish WA, US
Gor Nishanov - Redmond WA, US
Rajsekhar Das - Redmond WA, US
Gregorio Maeso - Redmond WA, US
Assignee:
Microsoft Corporation - Redmond WA
International Classification:
G06F 19/00
US Classification:
710 74, 709226
Abstract:
Described is a technology by which a storage volume is shared by cluster nodes of a server cluster. In one implementation, each node includes a redirector that provides shared access to the volume from that node. The redirector routes file system metadata requests from applications and the like through a first (e. g. , SMB) communications path to the owning node, and routes file system read and write data to the storage device through a second, high-speed communications path such as direct direct block level I/O. An owning node maintains ownership of the storage device through a persistent reservation mechanism that writes a key to a registration table associated with the storage device. Non-owning nodes write a shared key. The owning node validates the shared keys against cluster membership data, and preempts (e. g. , removes) any key deemed not valid.
