Redundant Storage Controller/Node

[iYAN]

Hi Community,

i want to Build a Storage for my ESX Servers, connected by iSCSI.
Some Supermicro-Server and TrueNas M-Series have two (or more) Compute/Server/Controller Nodes in a single Chassis.

is it possible to use active/active or active/passive Controller-Nodes to get more redundancy, if one Controller fail?
Or use both Nodes active/active to get more perfomance?

my "dreams" are a Redundant-Controller Storage with iSCSI and SSD/NVMe read/write cache.

Best Regards!

It sounds like you want the Enterprise features offered by the current TrueNAS product (in future to be TrueNAS Enterprise).

These are tied to hardware, so you can't just homebrew a server pair and run in HA though.

FreeNAS (future TrueNAS Core doesn't have an HA facility).

Only way of redundancy you can archive with the non Enterprise version is HBA redundancy with SAS dual port disk with multiple HBAs. Than PSU, network and maybe memory depending on your Mainboard.

For all other you need to buy truenas Enterprise.
Be aware that with version 12 dual port das disk will be an Enterprise feature... :(
