摘要： Systems and methods to forward data frames are provided. A particular method may include receiving a data frame at a distributed virtual bridge. The distributed virtual bridge includes a first bridge element coupled to a first server computer and a second bridge element coupled to the first bridge element and to a second server computer. The distributed virtual bridge further includes a controlling bridge coupled to the first bridge element and to the second bridge element. The controlling bridge includes a global forwarding table. The data frame is forwarded from the first bridge element to the second bridge element of the distributed virtual bridge using address data associated with the data frame. A logical network associated with the frame may additionally be used to forward the data frame.

摘要： Techniques are provided for multicast miss notification for a distributed network switch. In one embodiment, a bridge element in the distributed network switch receives a frame destined for a multicast group on a network. If a local multicast forwarding table of the bridge element does not include any forwarding entry for the multicast group, a forwarding entry is selected from the local multicast forwarding table as a candidate for being replaced. An indication of the candidate is sent to a management controller in the distributed network switch.

摘要： Systems and methods to multicast data frames are provided. A particular apparatus includes a plurality of computing nodes and a distributed virtual bridge. The distributed virtual bridge includes a plurality of bridge elements coupled to the plurality of computing nodes. The plurality of bridge elements are configured to forward a copy of a multicast data frame to the plurality of computing nodes using group member information associated with addresses of the plurality of server computers. A controlling bridge coupled to the plurality of bridge elements is configured to communicate the group member information to the plurality of bridge elements.

摘要： Performance counters are provided for virtualized network interfaces of communications networks, while minimizing the use of hardware resources. A virtualized network interface includes physical resources, as well as logical resources. Dedicated performance counters are provided for the physical resources of the virtualized network interface, as well as for logical partitions coupled to that interface, while non-dedicated performance counters are provided for the logical resources. This enables the provision of performance counters for virtualized network interfaces, while minimizing hardware resources consumed by those interfaces.

摘要： Computer systems with direct updating of cache (e.g., primary L1 cache) memories of a processor, such as a central processing unit (CPU) or graphics processing unit (GPU). Special addresses are reserved for high speed memory. Memory access requests involving these reserved addresses are routed directly to the high speed memory. Memory access requests not involving these reserved addresses are routed to memory external to the processor.

摘要： A data compression method and compression data structure are provided for a direct access storage device (DASD). The DASD is segmented into a plurality of compression groups. Each of the compression groups has a fixed logical size. A directory table is written within each of the compression groups. Each compression group has at least one compressed data region on which compressed data can be written and an exception region on which compressed data exceptions can be written. The compressed data exceptions include updated compressed data which exceeds an original storage space for corresponding original compressed data.

摘要： Techniques are provided for hash-based routing table management in a distributed network switch. A frame having a source address and a destination address is received. If no routing entry for the source address is found in a routing table of a switch module in the distributed network switch, routing information is determined for the source address and a routing entry is generated. The routing table is modified to include the routing entry and based on a set of hash functions.

摘要： Techniques are provided for hash-based routing table management in a distributed network switch. A frame having a source address and a destination address is received. If no routing entry for the source address is found in a routing table of a switch module in the distributed network switch, where the routing table is divided into slices of buckets, then routing information is determined for the source address and a routing entry is generated. The routing table is modified to include the routing entry and based on a set of hash functions and properties of the slices.
