Hi all,
I currently have a storage system running in a DC. It's a rather newly built system with 2 pools:
- 12x6TB (2 vdevs of RAIDZ2) 48TB pool mainly hosting media files but also diskless booting systems as well as backups - 2x S3700 as ZIL
- 12x2TB (6 mirrored vdevs) 12TB pool for VMs. - Optane 900p as ZIL
Server has 192GB of memory but yet, I am still seeing a ARC ratio of under 40% on average. sometimes it spikes but mostly it stays under 50%. Would now be a good time to get an L2ARC device? I have a 400GB Intel 750 SSD which I am not using. Server can still hold 64GB more of memory but I will have to buy the DIMMs first. I know people's usual opinion would be to max out the memory first but would it be worth a try to just install the NVMe SSD for now?
Thank you all in advance!
