The disclosed technology is generally directed to blockchain and other security technology. In one example of the technology, a first node is endorsed. During endorsement of a first node, a pre-determined type of blockchain or other security protocol code to be authorized and a pre-determined membership list are stored in a trusted execution environment (TEE) of the first node. A determination is made as to whether the membership lists and pre-determined blockchain or other security protocol code to be authorized from the proposed members match. If so, TEE attestation is used to verify that nodes associated with prospective members of the consortium store the pre-determined type of blockchain or other security protocol code to be authorized. Upon TEE attestation being successful, a consortium network is bootstrapped such that the prospective members become members of the consortium network.

Establishment of consortium blockchain network

The disclosed technology is generally directed to blockchain and other security technology. In one example of the technology, a pre-determined type of blockchain or other security protocol code is stored in a trusted execution environment (TEE) of the processor. TEE attestation is used to verify that the blockchain or other security protocol code stored in the TEE is the pre-determined type of blockchain or other security protocol code. A blockchain or other transaction is received and processed. Based on the processing of the transaction, an official state of the transaction on a consortium network is directly updated for the network. The updated official state of the processed transaction is broadcasted to the consortium network.

Datacenter configuration needs to be managed. A configuration engine (CE) manages configuration data of clusters and/or datacenters. The CE allows users to check out, edit, and check in configuration components. Versioned interfaces are placed between configuration components through data contracts. The CE supports the expression of constraints that ensure global consistency across configuration components and versions, isolates changes in the datacenter from structural changes in configuration components, and enables partial configuration branching to allow for active snapshots that enable configuration rollback. The CE ensures that types are consistent and constraints are satisfied at check-in time to eliminate unsound or inconsistent configuration in the first place. When the active configuration in the datacenter changes, multiple versions of configuration may be simultaneously deployed for a window of time. The managed set of configuration is permitted to have multiple active versions during these transitional windows to reflect the reality in the datacenter.

Globally sound and consistent configuration management for distributed datacenter components

Methods, systems, and computer-readable media for deploying an update to nodes propagated throughout a data center are provided. Launching new upgrade to hosting environment residing on the nodes typically invokes a mechanism (e.g., fabric controller) to form a group of nodes that are independent of one another with respect to upgrade domains, which are assigned to tenants (e.g., program components of service applications running within the data center) presently hosted by the nodes. The constraints of the update domains are articulated by service level agreements established for the service applications, respectively. Forming the group involves identifying independent nodes for membership, where no two members of the group host analogous tenants (belonging to a common service application) that are assigned to distinct update domains. However, it is acceptable to join to the group those nodes hosting analogous tenants that are each assigned to the same update domain.

Updating nodes considering service model constraints

Provided is a technique to automatically detect and recover a computer system after a failed attempt to read a partition, for example, a failed attempt to boot a target operating system, caused by corrupt disk metadata, such as a corrupt partition table metadata or a corrupt boot sector metadata.

Automatic detection and recovery of corrupt disk metadata

A method and apparatus to detect and mitigate disk failure is disclosed. The method may collect data from a disk from time to time and by analyzing the data, may provide an alert that there is a bad disk.

Detection and mitigation of disk failures

When a user-mode inpage error occurs after the system has booted up, the inpage error handling method attempts to prevent future crashes by repairing the faulting file. The fault may be a corrupt file or may be a disk I/O problem. The next time the now-repaired file is requested, execution should continue normally.
