- 2. Papers we love: ARC Discussing ARC: A self-tuning, low overhead replacement cache by Nimrod Megiddo and Dharmendra Modha Appeared in USENIX FAST 03 Has been broadly deployed in production most notably in ZFS, in at least illumos (SmartOS, etc.) and FreeBSD As much as possible, want to let the paper speak for itself and provoke discussion!

- 40. ARC: Epilogue The ARC is the basis of the cache used by ZFS, with many enhancements over time: Variable sized buffers though now returning to be 鍖xed blocks with ARC buffer data (ABD) L2ARC to allow SSDs to be used as a cache Separate metadata lists Compressed ARC A challenge has been to make all of ARC variable-sized
