The administrative agent topology provides the capability to remotely manage multiple base nodes on the same computer system with a single management server.

管理代理拓扑提供使用单个管理服务器远程管理同一计算机系统上的多个基本节点的功能。

Unlike in a traditional grid service, where the grid nodes are designated for a particular task and given work by a management server, in Gearman, workers instead ask for work to do.

在传统的网格服务中，网格节点由管理服务器指派给特定的任务和给定的工作，在Gearman中与此不同，是由工人请求做工作。

Decoupling refresh cycles lets data center customers purchase server compute nodes, which are essentially very small motherboards (processor, system memory, boot environment, management, and connection to a local network fabric), separately from rack-level data center network interfaces (1GbE and 10GbE), separately from mass storage (hard disks and solid-state drives).
