With the fast development of big data systems in recent years, a variety of open-source
benchmarks have been built to evaluate and compare the workloads on these systems, and …

Recent workload trends indicate rapid growth in the deployment of machine learning,
genomics and scientific workloads on cloud computing infrastructure. However, efficiently …

Flash storage has become the mainstream destination for storage users. However, SSDs do
not always deliver the performance that users expect. The core culprit of flash performance …

A longstanding goal of SSD virtualization has been to provide performance isolation
between multiple tenants sharing the device. Virtualizing SSDs, however, has traditionally …

We study storage performance in over 450,000 disks and 4,000 SSDs over 87 days for an
overall total of 857 million (disk) and 7 million (SSD) drive hours. We find that storage …

We analyze the manycore scalability of five widelydeployed file systems, namely, ext4, XFS,
btrfs, F2FS, and tmpfs, by using our open source benchmark suite, FXMARK. FXMARK …

We perform a detailed vertical analysis of application performance atop a range of modern
file systems and SSD FTLs. We formalize the" unwritten contract" that clients of SSDs should …

MittOS provides operating system support to cut millisecond-level tail latencies for data-
parallel applications. In MittOS, we advocate a new principle that operating system should …

Ensuring stable performance for storage stacks is important, especially with the growth in
popularity of hosted services where customers expect QoS guarantees. The same …

Distributed file systems often exhibit high tail latencies, especially in large-scale datacenters
and in the presence of competing (and possibly higher priority) workloads. This paper …
