[ovirt-users] recommendations for best performance and reliability

Hi, Can someone please give me some pointers, what would be the best setup for performance and reliability? We have the following hardware setup: 3x Supermicro server with following features per server: 128GB RAM 4x 8TB SATA HDD 2x SSD drives (intel_ssdsc2ba400g4 - 400GB DC S3710) 2x 12 core CPU (Intel(R) Xeon(R) CPU E5-2650 v4 @ 2.20GHz Quad port 10Gbe Inter NIC 2x 10GB Cisco switches (to isolate storage network from LAN) One of the servers will be in another office, with a 600Mb wireless link for Disaster Recovery. What is recommended for the best setup in terms of redundancy and speed? I am guessing GlusterFS with a Distributed Striped Replicated Volume across 3 of the servers. For added performance I want to use the SSD drives, perhaps with dm-cache? Should I combine the 4x HDD's using LVM on each host node? What about RAID 6? Virtual Machines will then reside on the oVirt Cluster and any one of the 3 host nodes can fail, or any single HDD can fail and all should still work, right/? -- Kind Regards Rudi Ahlers Website: http://www.rudiahlers.co.za
