Abstract: Storing data in persistent hybrid memory includes promoting a memory block from non-volatile memory to a cache based on a usage of said memory block according to a promotion policy, tracking modifications to the memory block while in the cache, and writing the memory block back into the non-volatile memory after the memory block is modified in the cache based on a writing policy that keeps a number of the memory blocks that are modified at or below a number threshold while maintaining the memory block in the cache.

Abstract: According to an example, a hybrid secure non-volatile main memory (HSNVMM) may include a non-volatile memory (NVM) to store a non-working set of memory data in an encrypted format, and a dynamic random-access memory (DRAM) buffer to store a working set of memory data in a decrypted format. A cryptographic engine may selectively encrypt and decrypt memory pages in the working and non-working sets of memory data. A security controller may control memory data placement and replacement in the NVM and the DRAM buffer based on memory data characteristics that include clean memory pages, dirty memory pages, working set memory pages, and non-working set memory pages. The security controller may further provide incremental encryption and decryption instructions to the cryptographic engine based on the memory data characteristics.

Abstract: Systems and methods of vertically aggregating tiered servers in a data center are disclosed. An example method includes partitioning a plurality of servers in the data center to form an array of aggregated end points (AEPs). Multiple servers within each AEP are connected by an intra-AEP network fabric and different AEPs are connected by an inter-AEP network. Each AEP has one or multiple central hub servers acting as end-points on the inter-AEP network. The method includes resolving a target server identification (ID). If the target server ID is the central hub server in the first AEP, the request is handled in the first AEP. If the target server ID is another server local to the first AEP, the request is redirected over the intra-AEP fabric. If the target server ID is a server in a second AEP, the request is transferred to the second AEP.
