Abstract: Toolless Compression Attached Memory Module (CAMM) installation systems and methods employ a bolster plate with a generally flat, parallelepiped body portion configured to contact one surface of a CAMM Printed Circuit Board (PCB) and provide compression between the CAMM and a z-axis compression connector. The bolster plate body defines (a) ramped keyhole(s), each ramped keyhole converts lateral displacement of the bolster plate into vertical displacement, providing the compression between the CAMM and the z-axis compression connector, by the ramped keyhole(s) sliding along (a) bottom face(s) of (a) head(s) of (a) fixed standoff(s) extending from an information handling system (IHS) PCB, through the z-axis compression connector and the CAMM PCB. The bolster plate may lock in place, laterally displaced, to maintain the compression between the CAMM and the z-axis compression connector. The bolster plate may also have a flange portion extending generally perpendicular from the body portion.

Abstract: Embodiments presented herein provide systems and methods for creating and modifying a hash chain. A hash chain is created to track resource-privilege transfers between entities. A root node of the hash chain identifies the resource and specifies a digest of a possession token held by a first entity that initially possesses the privilege. A transfer of the privilege to a second entity can be recorded by adding an expansion node to the hash chain. If the second entity successfully reveals a possession token that a hashing function associated with the hash chain maps to the digest, an expansion node is linked to the root node. The expansion node indicates the possession token and a successor digest that is based on a successor possession token.
