Flash Storage Evaluation

Overview

While there is an increasing need for high performance storage, such as all flash and hybrid storage solutions, 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 Load DynamiX Enterprise to test flash storage performance and determine the most appropriate flash or hybrid storage system that will support their constantly changing and growing workloads.

SSDs v HDDs to balance performance and costs

Figure: By using Load DynamiX, 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).

Your Challenges
Don’t rely on “standard” flash performance benchmark tests released by storage vendors, as they are produced in very tightly controlled lab settings, designed to showcase their products in the best possible conditions. They rarely represent real world environments or your production application workloads.

Other challenges include:

  • Difficulty in identifying dozens of potential bottlenecks which can make the use of solid state a waste of effort
  • Not enough people, time, and resources to adequately perform accurate testing and evaluation of flash storage
  • Vendors forced to make aggressive claims that don’t apply to your specific application workloads
  • Freeware tools can’t determine the performance impact of dedupe and compression
  • Determining the ROI of flash storage is usually guesswork at best. No one can afford excess over-provisioning and wasted capital expenses.

Load DynamiX Enterprise Solution Overview
Develop a workload model that allows you to accurately simulate how well the target storage systems under consideration will perform based on a variety of real-world testing scenarios. There is no need to rely on vendor claims and freeware benchmarking tools that simply don’t represent your environment. The Load DynamiX Enterprise solution includes:

  • Analyze/Characterize Workloads
  • Model Workloads
  • Emulate Workloads At Scale

Load DynamiX Enterprise 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.


Flash Storage Evaluation Solution Advantages
  • Performance assurance: Ensure your chosen flash / hybrid storage solutions will meet performance SLAs under your specific workloads. Choose between products from various vendors and ensures that storage acquisitions and configurations are aligned to application workload performance requirements.
  • Reduced storage costs: Accurately assess the benefit and effects of flash/SSDs, deduplication, and compression. Load DynamiX Enterprise provides independent validation for all vendor performance claims ensuring that IT organizations buy right. Know which workloads require solid state storage and which ones to remain on lower cost HDDs.
  • Acceleration of new application deployments: You can accelerate time to market by validating new applications and their supporting infrastructure; making deployment decisions faster and more confidently.
  • Reduced testing costs: Eliminate buying load generating servers and VMware licenses; one Load DynamiX Enterprise appliance generates the load of 10-20 servers and hundreds of VMs. Eliminate time consuming test development and scripting. Easier and repeatable testing often yields minimum productivity gains of 50%.
