Abstract: The present application is directed towards systems and methods of hunting for a hash table entry in a hash table distributed over a multi-node system. More specifically, when entries are created in an ASDR table, the owner node of the entry may replicate the entry onto a non-owner node. The replica can act as a backup of the ASDR table entry in the event the node leaves the multi-mode system. When the node returns to the multi-node system, the node may no longer have the most up to date ASDR table entries, and may hunt to find the existence of the value associated with the entry. Responsive to receiving a request for an entry that may be outdated on the node, the node sends a request down a replication chain for an updated copy of the ASDR table entry from one of the replicas. Responsive to receiving the replica copy of the entry, the node responds to the client's request for the entry.

Abstract: The present invention is directed towards systems and methods deploying a virtual server on a subset of devices in a cluster of devices. A first device of a cluster of devices intermediary between at least one client and at least one server, may identify a first virtual server to establish on one or more devices of the cluster. The first device may associate, to the identified virtual server, a group comprising a subset of devices in the cluster of devices. The cluster may establish the first virtual server on each device in the group responsive to associating the group to the first virtual server. Each virtual server on each device of the group may be assigned a same internet protocol address.

Abstract: The present application is directed towards using a distributed hash table to track the use of resources and/or maintain the persistency of resources across the plurality of nodes in the multi-node system. More specifically, the systems and methods can maintain the persistency of resources across the plurality of nodes by the use of a global table. A global table may be maintained on each node. Each node's global table enables efficient storage and retrieval of distributed hash table entries. Each global table may contain a linked list of the cached distributed hash table entries that are currently stored on a node.

Abstract translation: 本申请涉及在分布在多节点系统上的哈希表中搜索散列表条目的系统和方法。 更具体地说，当在ASDR表中创建条目时，条目的所有者节点可以将条目复制到非所有者节点。 在节点离开多模式系统的情况下，副本可以作为ASDR表条目的备份。 当节点返回到多节点系统时，节点可能不再具有最新的ASDR表条目，并且可以寻找找到与条目相关联的值的存在。 响应于接收到可能在节点上过时的条目的请求，节点从复制链路之一向ASDR表条目的更新副本发送针对复制链的请求。 响应于接收该条目的复制副本，节点响应客户端对该条目的请求。
