Providing higher workload resiliency in clustered systems based on health heuristics

02/04/16 - 20160036924 - Embodiments provide workload processing for clustered systems. In an illustrative, non-limiting embodiment, a computer-implemented method may include identifying a server as an active node of a cluster; assigning a workload to the server in response to the identification; determining, after the assignment, that the server is no longer an active

Resource arbitration for shared-write access via persistent reservation

08/14/14 - 20140229565 - Described is a technology by which an owner node in a server cluster maintains ownership of a storage mechanism through a persistent reservation mechanism, while allowing non-owning nodes read and write access to the storage mechanism. An owner node writes a reservation key to a registration table associated with the
Inventors: Rajsekhar Das, David A. Dion

Automatic transfer of workload configuration

01/02/14 - 20140007092 - The present invention extends to methods, systems, and computer program products for automatically transferring configuration of a virtual machine from one cluster to another cluster. The invention enables an administrator to transfer configuration of a virtual machine by simply specifying a virtual machine to be transferred. The invention then inspects
Inventors: Galen Dean Barbee, Symon Warner Perriman, David A. Dion, Lars Reuther, Joydeep Buragohain, Andrea D'amato, Alan Warwick, Ting Liang

Dynamic quorum for distributed systems

07/25/13 - 20130191453 - Managing a distributed system. Embodiments may allow for a quorum to dynamically change the quorum vote. One example is illustrated in a method. The method includes determining a change to a voter's level of participation in a cluster. A quorum of voters changes the voter's voting privileges, based on the
Inventors: Gor Nishanov, Andrea D'amato, Amitabh Prakash Tamhane, David A. Dion

Migration of virtual ip addresses in a failover cluster

06/20/13 - 20130159487 - The movement of a Virtual IP (VIP) address from cluster node to cluster node is coordinated via a load balancer. All or a subset of the nodes in a load balancer cluster may be configured as possible hosts for the VIP. The load balancer directs VIP traffic to the Dedicated
Inventors: Parveen Kumar Patel, David A. Dion, Corey Sanders, Santosh Balasubramanian, Deepak Bansal, Vladimir Petter, Daniel Brown Benediktson

Deployment of pre-scheduled tasks in clusters

03/14/13 - 20130067493 - Managing a triggerable task in a cluster environment. A method includes accessing a definition a task, wherein the definition includes a triggering event, and an action to be performed when the triggering event occurs. The method further includes, accessing a cluster policy defining how triggering events are interpreted on a
Inventors: David A. Dion, Lokesh S. Koppolu, Symon Perriman, Zongwei Sun, Mykyta Synytskyy, Maksym Yanchenko

Resource aware placement of applications in clusters

03/14/13 - 20130067267 - Placing an application on a node in a cluster. A method includes detecting an unexpected event indicating that an application should be placed on a node in the cluster. Real time information about resource utilization on one or more nodes in the cluster is received. Based on the real time
Inventors: Amitabh Prakash Tamhane, Mykyta Synytskyy, Lokesh S. Koppolu, David A. Dion, Andrea D'amato

Automatic preemption in multiple computer systems

03/14/13 - 20130067089 - Placing an application on a node in a cluster. A method includes determining that a first application cannot be placed on a first node in the first node's current running state. The method further includes determining that the first application may be able to be placed on the first node
Inventors: Mykyta Synytskyy, Amitabh Prakash Tamhane, Lokesh S. Koppolu, David A. Dion

Fault-tolerant communications in routed networks

10/25/12 - 20120272093 - A method for providing fault-tolerant network communications between a plurality of nodes for an application, including providing a plurality of initial communications pathways over a plurality of networks coupled between the plurality of nodes, receiving a data packet on a sending node from the application, the sending node being one

Consistent cluster operational data in a server cluster using a quorum of replicas

09/29/11 - 20110238842 - 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 maintain cluster operational data. A cluster operates when one node possesses a majority of replica members, which
