• Enlarging Industrial Scale

  With scaling up of Public Cloud and increasing Big Data business architectures, some partners have higher requirements on the storage performance in IAAS layer.

• Growing Energy Consumption

  With increasing number of single CPU cores in the cloud and data centers, physical disks cannot be split separately. As a result, the number of cores in a single VM instance increases, with one corresponding PCIe slot to be occupied by each VM.

• Diversified Business Requirements

  In order to provide partners with local disks in various specifications more flexibly, NVMe SSDs supporting SR-IOV application are urgently needed.

High-performance storage improves service efficiency: When planning the SR-IOV properties in the early stage, Union Memory optimizes the SR-IOV at the controller level and plans QoS capacity based on hardware capacity to isolate the performance of multiple virtual SSDs.

To verify the QoS capacity, the SSD performance is fully tested in the 8-way scenario.

The data shows that Union Memory’s property enables excellent QoS capacity and obvious isolation effect in terms of SR-IOV properties, basically having no interaction in service usage scenarios, and ensures large bandwidth and low latency of virtual SSDs even after SR-IOV is used.

One set of storage can meet a variety of application scenarios: At the beginning of SR-IOV design, and in order to ensure high performance and high reliability of products, Union Memory comprehensively considers and analyzes the requirements on service usage process, so that Union Memory’s SR-IOV properties can cope with various service processes and abnormal scenarios with responsive schemes and measures.

The test verification shows that Union Memory’s SR-IOV provides a highly reliable guarantee scheme in the three scenarios of new disk connection, disk power-down recovery, and abnormal disk replacement to ensure the operational stability and continuity of services in various scenarios.
