L1->L2->HDD Write Cache
Posted: Mon Apr 24, 2017 9:52 pm
I'm trailing using PrimoCache for easing bursts of network traffic to my backup server and using a 120GB partition off the boot SSD mirror as L2. We have bursts of data (around 60-100GB) from various systems that overwhelm the parity storage array and causes the array to perform very poorly. It seems PrimoCache does very well at caching this write-data to L1, but it skips by L2 completely.
Is there a way to use L2 SSD as write cache alongside L1 or can L2 only store read data?
