Disk drives are one of the most commonly replaced hardware components and continue to
pose challenges for accurate failure prediction. In this work, we present analysis and …

Emerging fast, persistent memories will enable systems that combine conventional DRAM
with large amounts of non-volatile main memory (NVMM) and provide huge increases in …

Fail-slow hardware is an under-studied failure mode. We present a study of 114 reports of
fail-slow hardware incidents, collected from large-scale cluster deployments in 14 …

Remote Data Checking (RDC) is a technique by which clients can establish that data
outsourced at untrusted servers remains intact over time. RDC is useful as a prevention tool …

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 …

The newly-emerging''fail-slow''failures plague both software and hardware where the victim
components are still functioning yet with degraded performance. To address this problem …

We analyze how modern distributed storage systems behave in the presence of file-system
faults such as data corruption and read and write errors. We characterize eight popular …

Non-volatile main memory (NVMM) allows programmers to build complex, persistent, pointer-
based data structures that can offer substantial performance gains over conventional …

To protect outsourced data in cloud storage against corruptions, adding fault tolerance to
cloud storage, along with efficient data integrity checking and recovery procedures …

In today's commercial data centers, the computation density grows continuously as the
number of hardware components and workloads in units of virtual machines increase. The …
