Storage capacity is becoming a real challenge for IT departments because the amount of data most companies use is growing faster than expected. Choosing the right way to scale IT storage infrastructure is vital to building a balanced, robust and cost-effective production environment.
Scale-out by StarWind Virtual SAN is the approach with the modern virtualization trend in mind. It is a much more efficient and cost-effective alternative to scale-up. The idea behind scale-out is to grow both storage and compute power by adding additional nodes instead of adding disks, CPUs, NICs or RAM to individual systems. Increasing the number of nodes increases reliability by eliminating single points of failure. It also gives customers a more flexible computing environment by treating all servers as a unified compute and storage resource pool. Adding nodes with the same hardware configuration isn’t necessary. Customers can add performance-tuned or capacity-tuned nodes depending on their IT environment requirements.
Implementing scale-out approach versus a scale up approach gives you a robust, well-balanced and easily scalable configuration. The scale-out approach gives IT administrators the following significant advantages:
