Abstract: A baseboard management controller (BMC) can physically partition the computing resources of a physical host into different resource groups for concurrently running a different operating system per resource group. The BMC can allocate a first processor of the host to a first resource group and a second processor of the host to a second resource group. The BMC can separate the memory of the host into a first memory range for the first processor and a second memory range for the second processor, and the BMC can limit access to the first memory range to the first processor and limit access to the second memory range to the second processor. The BMC can also distribute physical or virtual peripheral devices of the host between the first processor and the second processor.

Abstract: An example method for load balancing in a network environment is provided and includes receiving a packet from a first stage load-balancer in a network environment, where the packet is forwarded from the first stage load-balancer to one of a plurality of second stage load-balancers in the network according to a hash based forwarding scheme, and routing the packet from the second stage load-balancer to one of a plurality of servers in the network according to a per-session routing scheme. The per-session routing scheme includes retrieving a session routing state from a distributed hash table in the network. In a specific embodiment, the hash based forwarding scheme includes equal cost multi path routing. The session routing state can include an association between a next hop for the packet and the packet's 5-tuple representing a session to which the packet belongs.

Abstract translation: 提供了一种用于在网络环境中进行负载平衡的示例性方法，并且包括在网络环境中从第一级负载平衡器接收分组，其中分组从第一级负载平衡器转发到多个第二级负载 根据基于散列的转发方案在网络中平衡器，并且根据每会话路由方案将分组从第二阶段负载平衡器路由到网络中的多个服务器之一。 每会话路由方案包括从网络中的分布式哈希表检索会话路由状态。 在具体实施例中，基于散列的转发方案包括相同成本的多路径路由。 会话路由状态可以包括分组的下一跳与分组所属的会话的分组的5元组之间的关联。
