Cloud deployments disaggregate storage from compute, providing more flexibility to both the
storage and compute layers. In this paper, we explore disaggregation by taking it one step …

We introduce non-hierarchical caching (NHC), a novel approach to caching in modern
storage hierarchies. NHC improves performance as compared to classic caching by …

PCIe-attached solid-state drives offer high throughput and large capacity at low cost. Modern
servers can easily host 4 or 8 such SSDs, resulting in an aggregated bandwidth that hitherto …

For decades, ARIES has been the standard for logging and recovery in database systems.
ARIES offers important features like support for arbitrary workloads, fuzzy checkpoints, and …

We present an overview of SAP HANA's Native Store Extension (NSE). This extension
substantially increases database capacity, allowing to scale far beyond available system …

Persistent or Non Volatile Memory (PMEM or NVM) has recently become commercially
available under several configurations with different purposes and goals. Despite the …

Persistent or Non Volatile Memory (PMEM) offers expanded memory capacity and faster
access to persistent storage. However, there is no comprehensive empirical analysis of …

Intel® Optane™ DC Persistent Memory resides on the memory bus and approaches DRAM
in access latency. One avenue for its adoption is to employ it in place of persistent storage; …

Relational databases have gone through a phase of architectural transition from a
monolithic to a distributed architecture to take full advantage of cloud technology. These …

Hybrid storage systems are widely used in big data fields to balance system performance
and cost. However, due to a poor understanding of the characteristics of database block …
