[L2 Caching] Cache Priority and Modes

Post by JVini0166 »

One thing that would be cool too is to have Cache Priority and their modes.

Examples

L2 Caching Mode Extended:

Objetive: Cache 5TB Hard Drive and in the future add more drives.

L1 Cache - RAM

L2 Cache (1) - SSD NVMe (8GB)
L2 Cache (2) - SSD NVMe (64GB)
L2 Cache (3) - SSD NVMe (128GB)

when L2 (1) be full then use L2 (2), and when L2 (2) be full, use L2 (3),

This increase the flexibility for adding more and more disks for caching without changing the current ones.

L2 Caching Mode Stripped:

Objetive: Cache 10TB Hard Drive

L1 Cache - RAM

L2 Cache (1) - SSD NVMe (128GB) 25% of 100% cache here
L2 Cache (2) - SSD NVMe (128GB) 25% of 100% cache here
L2 Cache (3) - SSD NVMe (128GB) 25% of 100% cache here
L2 Cache (4) - SSD NVMe (128GB) 25% of 100% cache here

Result: L2 Cache 512GB as 100%

This will reduce wear in the SSDs and also speed by the four working together

L2 Caching Mode Safe Mode:

Objetive: turn the L2 Cache more reliable

L1 Cache - RAM

L2 Cache (1) - SSD NVMe (128GB) Active Disk
L2 Cache (2) - SSD NVMe (128GB) Backup Disk

when disconnected or failed one of disks

L2 Cache (1) - SSD NVMe (128GB) Stopped Disk
L2 Cache (2) - SSD NVMe (128GB) Backup Disk working as Active Disk until declares other disk as L2 Cache

This will increase the reability and can mantain the cache working for more time.

You may make a hardware or software SSD raid as level-2 cache.
