Here is how Fusion Data Acceleration works
Acceleration of random writes with Write Log (ZIL) on SSD (SATA/SAS/NVMe)
Hybrid Read Cache
First level in RAM (ARC – Adaptive Replacement Cache)
Second Read Cache level (L2ARC) on an SSD (SATA/SAS/NVMe)
- High cache hit rate by using ARC’s most recently used (MRU) and most frequently used (MFU) Read Cache algorithms.
- Data resilvering (rebuilding of used space).
- Compression and Deduplication for improved performance.
