[ovirt-users] Advice on deploying oVirt hyperconverged environment Node based

Hello All, I am about deploying a new Ovirt system for our developers that we plan to be hyperconverged environment Node based. The system workload would be mostly used for builders that compiling our code , which involves with lots of small files and intensive IO. I plan to build two glustered volume "layers" one based on sas drives for OS spin on, and second for Nvme based for intensive IO. I would expect that the system will be resilient/high availability and in the same time give enough good IO request for vm builders that will be at least 6 to 8 vm guests. The system hardware would be as follows: *chassis*: 4x HP DL380 gen8 *each server hardware:* *cpu*: 2x e5-2690v2 *memory*:256GB *Disks*:12x 1.2TB sas 10k disks , 2 mirror for os (or using usk kingstone 2x 128gb mirror) rest for vm os volume. *Nvme*: 2x960GB Kingstone KC1000 for builders compiling source code *Network: *4 ports Intel 10Gbit/s SFP + Given above configuration and theory, my question would be what would be best practice in terms of Gluster configuration *Distributed,Replicated,Distributed Replicated,Dispersed,Distributed Dispersed*? What is the suggestion for hardware raid type 5 or 6 , or use ZFS? Network nodes communication , i intend to use 3 ports for storage communication and one port for guests network , my question regarding Gluster inter communication , what is better would i gail from 3x 10G LACP or 1 network for each gluster volume? Please advice Thanks -- Tal Bar-or
