Package: wnpp Severity: wishlist X-Debbugs-CC: email@example.com Package name: dm-writeboost Version: 1.0.1 Upstream Author: Akira Hayakawa <firstname.lastname@example.org> License: GPL URL: https://github.com/akiradeveloper/dm-writeboost Vcs-Browser: http://anonscm.debian.org/cgit/collab-maint/dm-writeboost.git Description: log-structured caching for Linux dm-writeboost is an OS-level IO controller that builds logs from in-coming writes (data and metadata) and then writes the logs sequentially similar to log-structured filesystem. As a further extension, dm-writeboost supports read-caching which also writes data sequentially. . This package provides DKMS kernel module for Linux Kernel 3.10+. --- dm-writeboost highlights the following features: Durable: Any power failure can't break consistency because each log consists of data, metadata and the checksum of the log itself. Lifetime: Other caching software separates data and metadata (e.g. dm-cache) and therefore submits writes to SSD too frequently. dm-writeboost, on the other hand, submits only one writes for hundreds data and metadata so the SSD lives longer since SSD's liftime depends how many writes are submitted. Fast: Since the sequential write is the best I/O pattern for every SSD and the code base is optimized for in-coming random writes, the write performance is the best of all caching drivers including dm-cache and bcache. -- Regards, Dmitry Smirnov.
