Abstract: Examples described herein provide a computer-implemented method that includes receiving a plurality of profiles corresponding to at least one of a plurality of virtual machines. Each of the plurality of profiles defines a validity period and an allowable variation of time. The method further includes determining, based at least in part on the validity period, a subset of the plurality of profiles that are active. The method further includes calculating a uniform distribution for virtual clocks of each of the subset of the plurality of virtual machines and determining a desired offset. The method further includes adjusting a virtual clock frequency of a virtual clock based at least in part on the desired offset and the allowable variation of time. The adjusting causes a difference between a real time-of-day clock and a virtual time-of-day clock of the at least one of the virtual clocks to increase.

Abstract: Methods and systems include managing bandwidth in Fibre Channel over Internet Protocol (FCIP) communication channels. A method includes monitoring traffic demand at an FCIP communication channel and, in response to an anticipated period of throughput demand on the FCIP communication channel, reallocating physical throughput bandwidth of the FCIP communication channel by configuring bandwidth of one or more tunnels of the FCIP communication channel.

Abstract: A port speed of a port of a device is automatically set. A command is obtained at the device. The command provides an indication of a target port of the device and a selected port speed. Based on obtaining the command and using the device, a port speed of the target port is automatically set to the selected port speed.

Abstract: Embodiments include performing a host-initiated link reset in a storage area network (SAN). Aspects include identifying, by a host in communication with the SAN, each link in the SAN, wherein each link is defined by a pair of ports. Aspects also include obtaining, by the host, a buffer credit balance for each port in the SAN and obtaining, by the host, a buffer credit for each port in the SAN and causing a reset of a link associated with the port by transmitting a link reset record from the host to a control device of the link based on a determination that the buffer credit of a port in the SAN is below a threshold value.

Abstract: A port speed of a port of a device is automatically set. A command is obtained at the device. The command provides an indication of a target port of the device and a selected port speed. Based on obtaining the command and using the device, a port speed of the target port is automatically set to the selected port speed.

Abstract: A plurality of channels coupling at least one computing device to one or more devices are ranked. The ranking of a channel of the plurality of channels is based on one or more criteria including a size of a path group used to couple the channel to a device of the one or more devices. Based on the ranking, a selected channel of the plurality of channels is selected for which utilization state of the selected channel is to be changed. The utilization state of the selected channel is changed, in runtime, to reduce overall power consumption by the plurality of channels.

Abstract: An approach for extending encryption to input/output (I/O) on Peripheral Component Interconnect express (PCIe) links. The approach receives a proposal list of available encryption mechanisms. The approach selects an encryption mechanism from the proposal list, the encryption mechanism performs the encryption without encryption services from an associated Host Bus Adapter (HBA). The approach directs the I/O to the encryption mechanism.

Abstract: Aspects include includes receiving, at an input/output (I/O) processor, a transport control word (TCW) that includes an instruction to perform virtual port mirroring. The I/O processor identifies a first port to be mirrored and a virtual port to perform the mirroring. The virtual port is a first memory location in a memory. In response to outbound data being sent to the first port for transmission to a first target device and to the instruction specifying outbound port mirroring, the I/O processor stores a copy of the outbound data in the first memory location. In response to inbound data being received at the first port and to the instruction specifying inbound port mirroring, a copy of the inbound data is stored at the first memory location.

Abstract: An approach for improving endpoint security. The approach requests security capabilities from endpoints of communications. The approach can analyze the differences between the security capabilities of the endpoints. The approach can negotiate a security capability supported by the endpoints of the communication. The approach can determine if the negotiation succeeded. If the negotiation failed, then the approach can create a report describing capabilities of the endpoints and suggesting changes to improve the endpoint security. The approach can send the report to the appropriate interested personnel.
