Abstract: Methods, apparatus, systems and articles of manufacture manage credentials in hyper-converged infrastructure s are disclosed. An example method includes establishing, by executing an instruction with at least one processor, a communication between a software defined data center manager of the hyper-converged infrastructure and a component of the hyper-converged infrastructure using first credentials included in a known hosts file. The example method also includes generating, by executing an instruction with the at least one processor, second credentials at the component in response to a power-on event detected by the software defined data center manager. The example method also includes recording, by executing an instruction with the at least one processor, the second credentials at the known host file.

Abstract: Disclosed are various examples for top-of-rack (TOR) switch replacement in hyper-converged computing environments. A bring-up network configuration is applied to a network switch to install the network switch in a rack. An active workload within the rack is analyzed to identify a workload network configuration for the active workload. The active workload is reassigned to the network switch from a faulty network switch. The network switch is configured based on the workload network configuration for the active workload.

Abstract: Disclosed are various examples for improving the performance of an imaging service that can assign an IP address. The imaging service can implement the DHCP protocol and assign other configuration parameters using the DHCP protocol. An IP address cache can also be employed to speed a subsequent IP address assignment by the imaging service.

Abstract: Disclosed are various examples for validating a public SSH host key. The examples can be implemented in a hyper-converged computing environment to detect potential man-in-the-middle attacks in which an attacker intercepts or spoofs an internet protocol (IP) address of a target virtual machine (VM) that is being addressed by a management service and with which a secure shell (SSH) session is being established.

Abstract: Disclosed are various examples for top-of-rack (TOR) switch replacement in hyper-converged computing environments. A hyper-converged management service can maintain network configurations applied to a first network switch of a rack. When the performance of the first network switch does not satisfy a performance threshold, the hyper-converged management service can decommission the first network switch in the rack and configure a second network switch for replacement of the first network switch in the rack by accessing the at least one network configuration applied to the first network switch from the memory and applying the at least one network configuration to the second network switch.

Abstract: Disclosed are various examples for device replacement for device replacement in hyper-converged infrastructure environments. A workload hash for a workload to be processed by a hyper-converged compacting device can be compared to a device hash for the hyper-converged computing device to determine whether to assign the workload to the hyper-converged computing device for processing. When a new device is added to a hyper-converged infrastructure environment, a device has for the new device can be generated and workloads having low resources can be identified for reassignment to the new device.
