How to avoid storage network overload with Storage QoS

Every systems administrator who manages I/O intensive workloads is acutely aware of the problems that happen when storage controllers become overloadedapplications come to a screeching halt.

This is especially problematic for database administrators managing busy transactional workloads across multiple virtual machines. When storage devices come under load, you need to be able to utilize every available IOPS to maximize performance.

Windows Server 2016 with Storage Quality of Service (QoS) offers greater control over how you reserve IOPS for each virtual machine, enabling you to make more efficient use of storage bandwidth across virtual machines. Admins can set not only the maximum IOPs limit for each VM, but in a feature unique to Windows Server 2016, they can also set the minimum IOPs that should be allocated for each VM. This level of fine-tuned control means IT can optimize the performance of all available storage resources. Take a look at this brief demo:

Storage QoS offers two important advantages: 1) it helps you to get more bang for your storage buck by better utilizing the storage you already own, and 2) it makes storage performance more reliable, even for workloads with uneven traffic across virtual machines.
