Fast crash recovery in RAMCloud
2011
Proceedings of the Twenty-Third ACM Symposium on Operating Systems Principles - SOSP '11
Preserved Fulltext
RAMCloud is a DRAM-based storage system that provides inexpensive durability and availability by recovering quickly after crashes, rather than storing replicas in DRAM. ...

RAMCloud's crash recovery mechanism harnesses the resources of the entire cluster working concurrently so that recovery performance scales with cluster size. 7:2 J. Ousterhout et al. ...
The log-structured approach also simplifies crash recovery and utilizes DRAM twice as efficiently as traditional storage allocators such as malloc. ...
In addition, fast crash recovery requires fast failure detection, and the system must deal with secondary errors that occur during recovery. ...

But, when storing the data in RAM on thousands of servers one has to consider server failures. Only a few in-memory key-value stores provide automatic online recovery of failed servers. ...
The most prominent example of these systems is RAMCloud. Another system with sophisticated fault-tolerance mechanisms is DXRAM which is optimized for small data objects. ...
A fast reorganization is important to keep a constant write throughput (provide enough free space for writes) and to allow a fast crash recovery (less invalid/outdated objects to process). ...
