Hybrid Storage Pool: Top Speeds

I’d like to show the benefit of the Hybrid Storage Pool (HSP) in the simplest possible way, as an addition to my top speed results for the Sun Storage 7410. The HSP uses both read and write optimized flash based solid state disks (SSDs) to improve the performance of file I/O, with the ZFS L2ARC [...]

SLOG Screenshots

I previously posted screenshots of the L2ARC: the ZFS second level cache which uses read optimized SSDs (“Readzillas”) to cache random read workloads. That’s the read side of the Hybrid Storage Pool. On the write side, the ZFS separate intent log (SLOG) can use write optimized SSDs (which we call “Logzillas”) to accelerate performance of [...]
