Hi List,
At first, this really looks like a great project and I feel also that its very alive, so I am planning to do a test installation of sheepdog storage backed KVM I have already read what I could find about this project however there is not so much documentation out there yet. I have a couple of questions, I would appreciate if someone could enlighten me :-) 1. sheepdog needs at least two storage nodes to work, data is distributed like in a RAID1 therefore I always need the double of the capacity I plan to use for kvm guests, is there a Parity option that works like RAID5 ? 2. Does anyone has some performance numbers, with two nodes and 8HDD SAS Raid5 dual Gbit network bond What can I get for an estimated performance ? What is the bottleneck here, the network or the disks ? 3. Sheepdog uses the network to connect to the nodes, I guess it balances data in chunks over all available nodes, in the moment It stores each chunk on a node and a copy on another node, is this rotated over all nodes or is each image fixed on two nodes ? 4. As sheepdog uses the network as a transport medium am how high is the latency, is this an issue in production networks ?
