zfs without ssd cache

[fusion]

Hello, has anyone tried to have 2 sata drives in RAID 1 zfs without ssd cache? , I want to use to set up a virtual machine with Cpanel, and one with zimbra ..

machine1:

Intel Xeon E5
E5-1630v3 4c/8t
3,7 / 3,8 GHz 32 GB RAM
DDR4 ECC 2133 MHz 2x4TB SOFT

or better this machine? With lower processor but with twice the RAM

Intel Xeon D
D-1520 4c/8t
2,2 / 2,6 GHz 64 GB RAM
DDR4 ECC 2133 MHz 2x2TB + 2x300GB SSD SOFT


Thank you

Cheers

Should work with both options fine. Maybe with the first option you should set the memory consuming of zfs to 8GB. ZFS try alway half of your whole memory: https://pve.proxmox.com/wiki/Storage:_ZFS#Limit_ZFS_memory_usage
