Pendahuluan Bcache adalah teknologi cache terhadap block device yang memungkinkan kita menggabungkan 2 perangkat SSD/NVMe dan HDD sehingga kita bisa mendapatkan performa baca tulis yang lebih baik. Caching akan dilakukan pada SSD (Caching Device) dan data tetap akan disimpan pada HDD (Backing Device). Glosari Bcache: Linux kernel block layer cache Backing Device: Tempat data disimpan (Biasanya HDD) Cache Device: Tempat cache disimpan (Biasanya SSD/NVMe) Panduan Membuat bcache backing device make-bcache -B /dev/vdb Membuat bcache cache device make-bcache -C /dev/vdc Contoh output lsblk ...
