摘要： Diskette media and drive determination in which a diskette controller attempts to read the diskette according to a variety of formats having, for instance, different data transfer rates. A successful read is registered by the controller and that format is thereafter identified with the diskette drive and the diskette media inserted in the drive.

摘要： Diskette drive determination in which a read/write head in a diskette drive is instructed to move to a track that is inaccessible on one type of diskette drive. The head is then stepped back toward a track associated with a sensor indicating the positioning of the head over the track. The number of steps required to activate the sensor determines which type of drive is being used.

摘要： Virtual machines are managed on the basis of data obtained from a management information database of a network switch having a plurality of Ethernet links coupled to compute nodes running a plurality of virtual machines. A management entity, such as a provisioning manager, determines the amount of network bandwidth being utilized through each of the Ethernet links. Accordingly, an additional virtual machine may be provisioned to the compute node that is coupled to an Ethernet link identified as having the greatest amount of unutilized network bandwidth.

摘要： Method and computer program for managing the network response times experienced by virtual machines. Traffic is routed within an Ethernet network through a network switch according to IP addresses identified within Ethernet frames. A plurality of compute nodes are each coupled to the network switch via a separate Ethernet link. A response time is determined for each virtual machine running on the compute nodes, wherein the response time for a particular virtual machine is the difference between a time stamp in a TCP/IP Request message and a time stamp in a TCP/IP Response message for an IP address assigned to the particular virtual machine. The particular virtual machine may then be migrated to a target compute node in response to a particular one of the virtual machines on a particular one of the compute nodes having a response time that exceeds a response time setpoint.

摘要： Virtual machines are managed on the basis of data obtained from a management information database of a network switch having a plurality of Ethernet links coupled to compute nodes running a plurality of virtual machines. A management entity, such as a provisioning manager, determines the amount of network bandwidth being utilized through each of the first and second Ethernet links and the amount of network bandwidth being utilized by the Internet Protocol addresses attributable to each of the virtual machines. Accordingly, one of the virtual machines may be migrated from one compute node to another compute node coupled to an Ethernet link having a greater amount of unutilized network bandwidth. Virtual machines may be dynamically migrated in order to provide each virtual machine with a required amount of network bandwidth.

摘要： Migrating virtual machines among networked servers, the servers coupled for data communications with a data communications network that includes a networking device, where migrating includes: establishing, by a virtual machine management module (‘VMMM’), one or more virtual machines on a particular server; querying, by the VMMM, the networking device for link statistics of a link coupling the network device to the particular server for data communications; determining, by the VMMM in dependence upon the link statistics, whether the link coupling the network device to the particular server is degrading; and if the link coupling the network device to the particular server is degrading, migrating a virtual machine executing on the particular server to a destination server. In some embodiments, migrating occurs is carried out only if non-degrading link is available. If no non-degrading links are available, the network device, rather than the link, may be failing.
