Re: [ovirt-users] Good practices

I am willing to assemble a oVirt "pod", made of 3 servers, each with 2 CPU sockets of 12 cores, 256GB RAM, 7 HDD 10K, 1 SSD. The idea is to use GlusterFS to provide HA for the VMs. The 3 servers have a dual 40Gb NIC and a dual 10Gb NIC. So my intention is to create a loop like a server triangle using the 40Gb NICs for virtualization files (VMs .qcow2) access and to move VMs around the pod (east /west traffic) while using the 10Gb interfaces for giving services to the outside world (north/south traffic). This said, my first question is: How should I deploy GlusterFS in such oVirt scenario? My questions are: 1 - Should I create 3 RAID (i.e.: RAID 5), one on each oVirt node, and then create a GlusterFS using them? 2 - Instead, should I create a JBOD array made of all server's disks? 3 - What is the best Gluster configuration to provide for HA while not consuming too much disk space? 4 - Does a oVirt hypervisor pod like I am planning to build, and the virtualization environment, benefits from tiering when using a SSD disk? And yes, will Gluster do it by default or I have to configure it to do so? At the bottom line, what is the good practice for using GlusterFS in small pods for enterprises? You opinion/feedback will be really appreciated! Moacir _______________________________________________ Users mailing list Users(a)ovirt.org http://lists.ovirt.org/mailman/listinfo/users
