There is a lot of need for new requirements regarding data collection, analysis, and large data storage. This need has arisen from the development of various industries such as 5G applications, autonomous cars, big data, and Artificial Intelligence (AI). We can expect that the data volume requirement will raise at least 5 times from CY2018 to CY2025.<\/p>\n

This rise in data volume requires storage devices to handle large amounts of data with the shortest latency possible. Providing high-quality service to support multiple functions with one drive has become a hot topic in recent years.<\/p>\n

An important indicator to evaluate the performance of Enterprise SSD<\/a> is Quality of Service (QoS). Single Root I\/O Virtualization (SR-IOV) is a commonly used application by the good QoS of enterprise SSD. Generally, the host will implement a virtual switch mechanism to divide the data resource to each virtual machine, which will cause transition latency and impact the QoS. One way to combat this is to apply SR-IOV to physical devices. This will allow the dedication of bandwidth for each virtual machine without getting through the virtual switch, resulting in less latency with better QoS.<\/p>\n
