The question: Is CFS scalable? What performance hit is there from running VxFS in a clustered configuration?
Often times in sales situations, we are asked what the performance implications are of running CFS.
Customers are eager to know what the performance hit would be from operating in a clustered environment. This is particularly interesting to customers who are considering deploying our CFS HA solution as an upgrade to the regular Storage Foundation HA solution. They want want to know what CFS is going to cost in performance, and so did we.
The test: Run a workload on 1, 2, 4, 8, and 16 nodes and measure throughput.
With the outstanding efforts of the Performance Enigneering Group, we were able to measure...
