The monolithic server model where a server is the unit of deployment, operation, and failure
is meeting its limits in the face of several recent hardware and application trends. To improve …

Resource-disaggregated architectures have risen in popularity for large datacenters.
However, prior disaggregation systems are designed for native applications; in addition, all …

Modern block-addressable NVMe SSDs provide much higher bandwidth and similar
performance for random and sequential access. Persistent key-value stores (KVs) designed …

Emerging byte-addressable nonvolatile memories (NVMs) promise persistent memory,
which allows processors to directly access persistent data in main memory. Yet, persistent …

The adoption of low latency persistent memory modules (PMMs) upends the long-
established model of remote storage for distributed file systems. Instead, by colocating …

PCIe-based Flash is commonly deployed to provide datacenter applications with high IO
rates. However, its capacity and bandwidth are often underutilized as it is difficult to design …

We describe the design, implementation, and evaluation of Occult (Observable Causal
Consistency Using Lossy Timestamps), the first scalable, geo-replicated data store that …

Cloud block storage systems support diverse types of applications in modern cloud services.
Characterizing their I/O activities is critical for guiding better system designs and …

DFSCQ is the first file system that (1) provides a precise specification for fsync and
fdatasync, which allow applications to achieve high performance and crash safety, and (2) …

This paper introduces the first state-based formalization of isolation guarantees. Our
approach is premised on a simple observation: applications view storage systems as black …
