Techniques are disclosed for managing inventory data for components of a server system. In one embodiment, a global management controller is provided, that is operatively connected to a plurality of local management controllers. Each local management controller is configured to manage a subset of the components of the server system. Each local management controller is also configured to generate, for each component, a checksum based on vital product data (VPD) of the component. Each local management controller is also configured to compute a composite checksum based on the checksums generated for the components in the subset. The global management controller is configured to maintain a global view of the VPD in the computer system, based on the checksums and/or composite checksums.

Managing inventory data for components of a server system

Embodiments of the present invention provide a novel and non-obvious method, system and computer program product for an Internet protocol (IP) address resolution process during an original switch stack fragmentation, by employing a secondary communication link. A method for IP address resolution of a fragmented switch stack over a secondary communication link (e.g., an I2C bus) can include detecting a first switch stack fragment by a first stack master, detecting a second switch stack fragment by a second stack master, disabling all switches of the first switch stack fragment and the second switch stack fragment, connecting the first stack master and the second stack master to a stack management module via a secondary communication link, and electing one stack fragment to use the IP address of the original switch stack based on at least one election criteria. The method can further include instructing the stack master of the elected one stack fragment to power up the switches of the elected one stack fragment.

A method, system and computer-usable medium for managing electronic mail (email) attachments. An email message comprising a first recipient list and a first file attachment is received from a sender. A response email is generated, comprising a second recipient list. The first recipient list and the second recipient list are compared and a third recipient list is generated comprising recipients that are listed on the second recipient list, but not on the first. The email response is then transmitted to all recipients that are on the second recipient list but not on the third list, and the email response and the first file attachment is sent to the recipients on the third recipient list.
