While there is an increasing need for flash storage performance, there is a risk that storage architects could just be blindly throwing expensive hardware at performance issues.
Leading IT organizations who care about performance scalability and cost/performance such as Go Daddy, Shutterfly and Cox Communications use WorkloadWisdom to test flash storage performance and determine the most appropriate flash or hybrid storage system that will support their constantly changing and growing workloads. When every vendor’s datasheet promising sub-second latency and 1 million IOPS, how do you know if they perform with your applications?
SSDs v HDDs to balance performance and costs
Figure: By using WorkloadWisdom, different arrays will perform differently using varied amounts of repeating data. Vendor B exhibits higher IOPS when data is 20% or 50% reducible, with any read/write ratios, but especially with higher reads. Vendor A shines when data is highly reducible and read/write ratios are in the 50% range (or greater).
Other challenges include:
WorkloadWisdom tests and validates flash with deduplication and compression with high accuracy, tremendous load and extremely realistic workload patterns. We have a patent pending method of generating and verifying streams that represent repeatable random and repeatable compressible content.
