Abstract: A storage control apparatus forms a RAID by plural storage media and stores and holds data on a file-by-file basis. A number-of-writable-times management unit manages the number of writable times for each storage medium. A write-destination management unit manages data write destinations in the storage media. When updating write object data whose write destination is one of storage media constituting a group (first storage medium), a relocation unit relocates the write object data by setting a write destination to a second storage medium which is different from the first storage medium. A write-destination update unit updates the data write destinations in the storage media managed by the write-destination management unit according to the relocating. Through the relocating, the storage control apparatus is able to control the number of writable times which decreases along with data writing.

Abstract: The present disclosure discloses a method and a network device for failure detection of nodes in a cluster. Specifically, a network device transmits data to another device at a first time. The network device then receives an acknowledgment of the data from the second device at a second time. Next, the network device determines a Round Trip Time (RTT) for the first device and the second device based on the first time and the second time. Based on the RTT, the network device determines a first frequency for transmitting a heartbeat protocol message between the first device and the second device, and transmits a heartbeat protocol message between the first device and the second device at the first frequency.

In one embodiment, the memory reserved for HA failover is determined in each host computing system of the HA cluster. Further, the memory reserved for HA failover is assigned to one or more virtual machines in the HA cluster as input/output (I/O) cache memory at a first level.

Abstract: An electronic fault detection unit is provided that has a first register, a second register, a comparator circuit, and a timer circuit. The first and second register can be written from a first software portion, and a second software portion, respectively. The comparator circuit is arranged to detect that both the first and second register have been written, verify a relationship between first data written to the first register and second data written to the second register, and signal a fault upon said verification failing. The timer circuit is arranged to signal a fault if said verification of the comparator circuit does not occur within a time limit.

Abstract: A fleet rebuild service examines hosts in a fleet to determine whether any of the hosts in the fleet are to be rebuilt. If a host is to be rebuilt, the fleet rebuild service moves the host to a vetting pool. The fleet rebuild service, or another service, may cause automated testing to be performed on the hardware and/or software of hosts in the vetting pool. If a host passes the automated testing, the fleet rebuild service may move the host from the vetting pool to a provisioning pool. If a host does not pass the automated testing, the host may be moved from the vetting pool to a diagnostics pool for further testing. The fleet rebuild service may select hosts from the provisioning pool for automated configuration and deployment to the fleet.

Abstract: Services associated with first and second nodes are managed. As part of the management, the first node receives a request to modify the services. A synchronization policy is identified. The synchronization policy requires that modifications attempted on the set of services on the first node also be attempted on the second node. In response to the request, an attempt is made to modify the set of services on the first node. Further, in response to the request and pursuant to the synchronization policy, the second node is caused to attempt to modify the set of services. The synchronization policy is identified as a relaxed synchronization policy. A determination is made that the attempt to modify the set of services on the second node failed. Based on identifying that the synchronization policy is a relaxed synchronization policy, the attempt to modify the set of services on the first node continues.

An event log record is used to determine whether a connection failure event occurred with a primary provider system of the service. An evaluation is made whether the request can be routed to the failover provider system. The request is routed to the failover provider system.
