To combine or not to combine storage?

[IamSpartacus]

Current setup is as follows...

FreeNAS Server: Shared VM storage server for ESXi hosts

• 2 different zpools (Tier1, Tier2) consisting of 4 SSD's in RAID10 each.
• Xeon D-1508 (2-core/4thread), 16GB RAM, Dual 10Gb NICs

UnRAID Server: Bulk storage of all media, surveillance data, backups, software, personal data

• Main function is just bulk storage presented to VM's via NFS mounts (mainly Emby for media streaming)
• Also run an Active Directory DC on this so that if my VM infrastructure is down I still have DHCP, DNS, Mapped Drives, etc.
• 6 x 8TB Seagate SMR drives + 2 SSDs in RAID0 cache pool for writes/VMs
• Xeon D-1518 (4-core/8-thread), 32GB RAM, Dual 10Gb NICs

I just purchased 8x10TB WD Gold drives to replace the 8TB Seagate SMRs in UnRAID. I'm wondering if there is any good reason NOT to combine my current FreeNAS zpools into the same storage server as these new WD Gold bulk drives (I'd create an 8 disk RAIDz2 zpool). I'd use the Xeon D-1518 with the 48GB of RAM or maybe just pickup a second 32GB module to make it 64GB.

Thoughts?

I would. Just keep the vm pool separate

Care to elaborate on that thought at all? I'm trying to scale back on the amount equipment /power I'm using so I really wanna get all my storage into one box.
