Abstract: Mechanisms for efficient discovery of storage resources in a Rack Scale Architecture (RSA) system and associated methods, apparatus, and systems. A rack is populated with pooled system drawers including pooled compute drawers and pooled storage drawers communicatively coupled via input-output (IO) cables. Compute nodes including one or more processors, memory resources, and optional local storage resources are installed in the pooled compute drawers, and are enabled to be selectively-coupled to storage resources in the pooled storage drawers over virtual attachment links. During a discovery process, a compute node determines storage resource characteristics of storage resources it may be selectively-coupled to and the attachment links used to access the storage resources. The storage resource characteristics are aggregated by a pod manager that uses corresponding configuration information to dynamically compose compute nodes for rack users based on user needs.

Abstract: When a processing system boots, it may retrieve an encrypted version of a cryptographic key from nonvolatile memory to a processing unit, which may decrypt the cryptographic key. The processing system may also retrieve a predetermined authentication code for software of the processing system, and the processing system may use the cryptographic key to compute a current authentication code for the software. The processing system may then determine whether the software should be trusted, by comparing the predetermined authentication code with the current authentication code. In various embodiments, the processing unit may use a key stored in nonvolatile storage of the processing unit to decrypt the encrypted version of the cryptographic key, a hashed message authentication code (HMAC) may be used as the authentication code, and/or the software to be authenticated may be boot firmware, a virtual machine monitor (VMM), or other software. Other embodiments are described and claimed.
