摘要： An I/O adapter is installed in a slot in a computer system. Online deletion of the I/O adapter is achieved by a three step process, in which a device driver that controls the adapter first attempts to quiesce the adapter, the slot is then powered off, if it is possible to do so, and finally, if the quiesce operation was successful or the slot is powered off, the driver completes the delete operation by unmapping buffers and cleaning up datastructures associated with the device driver.

摘要： Techniques are provided for improve quality of service on uplinks in a virtualized environment. At a server apparatus having a plurality of physical links configured to communicate traffic over a network to or from the server apparatus, forming an uplink group comprising a plurality of physical links. A first class of service is defined that allocates a first share of available bandwidth on the uplink group, and a second class of service is defined that allocates a second share of available bandwidth on the uplink group. The bandwidth for the first class of service is allocated across the plurality of physical links of the uplink group, and the bandwidth for the second class of service is allocated across the plurality of physical links of the uplink group. Traffic rates are monitored on each of the plurality of physical links to determine if a physical link is congested indicating that a bandwidth deficit exists for a class of service. In response to determining that one of the plurality of physical links is congested, bandwidth is reallocated for a class of service to reduce the bandwidth deficit for a corresponding class of service.

摘要： Described herein are techniques for preventing MAC address spoofs in a virtualization cluster. When a virtual switch first sees a new MAC address on a port designated as being a secure port, the packet is redirected to a virtual supervisor agent used to manage the distributed virtual switch. Assuming the MAC may be bound to the secure port, the supervisor agent broadcasts a message to both the virtual switch that redirected the packet and to virtual switches on other virtualization servers within the cluster.
