    • Presented systems and methods can facilitate efficient and effective information storage management. A system may include a plurality of nodes, shared storage and a centralized lock manager. A storage management method can include: receiving an access request to information, performing a lock resolution process; and performing an access operation (e.g., read, information update, etc.). The information can be associated with a shared storage component. The lock resolution process can include participating in a lock management process that manages a physical lock (P-lock), wherein the lock management process utilizes transaction information associated with an implicit lock process and proceeds without communication overhead associated with explicit requests for a logical lock. In one embodiment the lock resolution process includes participating in a conflict determination process to determine if there is a potential conflict with an information access request, wherein the conflict determination process utilizes the transaction information associated with the implicit lock process.
    • 提出的系统和方法可以促进有效和有效的信息存储管理。 系统可以包括多个节点,共享存储器和集中式锁管理器。 存储管理方法可以包括:接收对信息的访问请求,执行锁定解析处理; 并执行访问操作(例如,读取,信息更新等)。 信息可以与共享存储组件相关联。 锁解决过程可以包括参与管理物理锁(P锁)的锁管理过程,其中锁管理过程利用与隐式锁处理相关联的事务信息,并且进行而不涉及与逻辑锁的显式请求相关联的通信开销 。 在一个实施例中,锁解决过程包括参与冲突确定过程以确定是否存在与信息访问请求的潜在冲突,其中冲突确定过程利用与隐式锁定过程相关联的交易信息。
