Lethe: Secure Deletion by Addition
Modern data privacy regulations such as GDPR, CCPA, and CDPA stipulate that data pertaining to a user must be deleted without undue delay upon the user's request. Existing systems are not designed to comply with these regulations and can leave traces ...
An Evaluation of DAOS for Simulation and Deep Learning HPC Workloads
Traditionally, distributed storage systems have relied upon the interfaces provided by OS kernels to interact with storage hardware. However, much research has shown that OSes impose serious overheads on every I/O operation, especially on high-...
Intelligent Data Migration Policies in a Write-Optimized Copy-on-Write Tiered Storage Stack
Modern storage stacks increasingly aim to intellegently optimize data accesses to improve latency, throughput, and energy consumption. Additionally, new storage setups become more heterogeneous, due to the introduction of new storage media, like NVM, ...
Is Bare-metal I/O Performance with User-defined Storage Drives Inside VMs Possible?: Benchmarking libvfio-user vs. Common Storage Virtualization Configurations
It is a critical concern for cloud computing providers to identify and adopt optimal virtual machine (VM) I/O storage paths. In Linux, these involve NVMe hardware, PCIe passthrough with vfio, and userspace drivers (e.g. SPDK). One project tying ...
Performance Characterization of Modern Storage Stacks: POSIX I/O, libaio, SPDK, and io_uring
Linux storage stack offers a variety of storage I/O stacks and APIs such as POSIX I/O, asynchronous I/O (libaio), high-performance asynchronous I/O (emerging io_uring) or SPDK, the last of which completely bypasses the kernel. Despite their ...
