Whats the maximum size for L2 cache? if I set it to 1tb it crashes? 512mb works fine.

There's no limit. Should not crash in any case. Brought R&D guys attention on that. Thank you for reporting.

Hi,
Having so much cache that large may cause data loss in the event of a power outage. Also, L2 cache, by its design boosts only reads; see more about caching
https://knowledgebase.starwindsoftware. ... rinciples/. You can boost both reads and writes by putting a HA device on the device intended for the L2 cache.

ok got it (RTFD)
1To for 6.5 RAM.... That was the trick. I added RAM on the VM and it works perfectly.
I don't get why we could loose any data. If it's a cluster with 2 nodes and a HA device with same parameters L1 and L2 cache (WT).

Oops, mixed L2 with L1. I'm sorry. Thanks for the update. Anything else I can assist you with?
