New Server Recommendations

[sahostking]

Hi guys

This is our server specs:

• Intel Xeon E5-2620

• 64 GB ECC RAM - We usually end up using around 30GB or so per server and the rest is free.

• H/Ware RAID 6 or 10 (battery backup)

• 6 x SSD Disks

We have always used LVM thin on our servers since Proxmox 4.x but find it slower than when we used Proxmox 3.4 on the same hardware. The only difference we assume is it uses LVM thin now compared to LVM2 and also it now uses ext4 compared to ext3.

Restoring VMs from one server to another from our backup storage kills all servers temporarily.

What do you think is a better option for setup? Any ideas? or recommendations?

Drop hw-raid, and use zfs...

Good idea will look into that. Also will there be massive impact on performance if we did the following as we host cpanel KVM VPS servers and Plesk KVM VPS servers?

2 x 500GB SSD Disks in RAID 1 (MySQL disks and OS disks)
4 x 1TB Sata Enterprise Disks in RAID 10 (data and /home disks)

We used pure SSD setup before and we can only take 6 disks in these servers. But considering the above for cost saving? Anyone have experiences or thoughts on this idea?
