Hardware for proxmox VE

[jaj1105]

Hello,
I planned to start virtualization in few days - weeks in my company.

• 1 VM Windows RDS for around 20 clients
• 1 VM Windows for BDD
• 1 VM Active Directory
• 2 VM Debian with postfix and Kaspersky for linux mail server
• 2-3 VM for test

I planned 4 x 2TO SAS HDD 7.2k rpm and 2 960Go SSD and BDD.
It is better to use zfs raid than a controller raid?

Is it possible to use 2 SSD disk of 960Go in raid 1 only for BDD and systems?

I need advice to buy the right server, thanks in advance.

Best regards,

Joseph

If you use ZFS don't use it in combination with a RAID controller.
You can install the system on a ZFS Raid 1 on SSDs and use it for VMs too. Get enterprise SSDs because consumer SSDs can wear out quite quickly in server environment.

Others might have some experience in regards to I/O and also RAM and CPU power.

To and Go

Wow, I'm in the IT for so long and I never saw this unit before, but I really like it!

Let's jump into the other questions:

Is it possible to use 2 SSD disk of 960Go in raid 1 only for BDD and systems?

Yes, unconditionally.
As @aaron already pointed out: Either use hardware raid with e.g. LVM or QCOW2 or no raid controller and ZFS.

I need advice to buy the right server, thanks in advance.

I'd go with enterprise components, so no commodity or prosumer hardware. Decent server board, e.g. Supermicro, ECC RAM and if you want to have a raid controller, go with a battery or capacitor one with a huge cache for a fast system. If you want to have the possibility and goal to increase hardware in the future, I would not populate all memory slots, just go with modules with more memory instead of filling it up already. You can also choose if you want to have a single CPU or dual CPU system with only one socket populated (be aware that not all memory and pcie slots work if only one slot is populated).
