    • This invention is comprised of a data processing system containing at least one main processor connected to a system bus, a system memory connected to the system bus and accessible to each of the main processors, a tamper mechanism, and a local service processor. The tamper mechanism is configured to change state each time the system is inserted into a slot in a rack enclosure. The local service processor is connected to the tamper mechanism and configured to update an insertion log upon detecting a change in state of the tamper mechanism. The insertion log provides a count and a history of rack insertions to which the system has been subjected. The system may include a non-volatile storage element which is updated exclusively by the local service processor that contains the insertion log. The insertion log may include an insertion counter. In this embodiment, the local service processor is configured to increment the insertion counter upon each insertion. The local service processor may be further configured to issue an alert if the insertion counter exceeds a predetermined value. In one embodiment, the system further includes a battery backed real-time clock connected to the local service processor. The local service processor is configured to include real-time information corresponding to each insertion event in the insertion log. Each entry in the insertion log may include the identity of the rack enclosure and the geographical address of the slot of the corresponding insertion event. The local service processor may be configured to detect the tamper mechanism state and update the insertion following a power event such that the insertion log update is independent of configuring the data processing system with a boot image.
    • 本发明包括一个数据处理系统,该数据处理系统包括连接到系统总线的至少一个主处理器,连接到系统总线并且可被每个主处理器访问的系统存储器,篡改机制和本地服务处理器。 篡改机制被配置为每当系统插入机柜中的插槽时改变状态。 本地服务处理器连接到篡改机制,并且被配置为在检测到篡改机制的状态变化时更新插入日志。 插入日志提供系统受到的机架插入的计数和历史记录。 系统可以包括由包含插入日志的本地服务处理器专门更新的非易失性存储元件。 插入日志可以包括插入计数器。 在该实施例中,本地服务处理器被配置为在每次插入时递增插入计数器。 本地服务处理器还可以被配置为如果插入计数器超过预定值则发出警报。 在一个实施例中,系统还包括连接到本地服务处理器的电池支持的实时时钟。 本地服务处理器被配置为包括与插入日志中的每个插入事件相对应的实时信息。 插入日志中的每个条目可以包括机架机柜的标识和相应插入事件的时隙的地理位置。 本地服务处理器可以被配置为检测篡改机制状态并且在功率事件之后更新插入,使得插入日志更新独立于使用引导映像配置数据处理系统。
