Data center infrastructures are typically divided into three categories: traditional, converged, and hyperconverged. Hyperconverged infrastructures allow users to add compute, memory, and storage as needed, providing the flexibility to scale out and scale in. However, many virtual machine (VM) configurations run on converged infrastructures, and their ability to scale out often becomes more difficult when VM clusters require more memory.
VMware®, Inc. delivers hyperconverged infrastructures with VMware ESXi™ and VMware vSAN™ platforms. VMware ESXi is a popular enterprise-class virtualization platform that enables you to scale compute and memory on demand and easily manage large clusters of virtual machines. VMware vSAN enables you to move from converged to hyperconverged infrastructures, delivering incredibly high performance because storage is localized on the servers themselves. The platforms support the new VMware vSAN Express Storage Architecture™ (ESA), which has undergone a number of optimizations to more efficiently utilize NVMe solid-state drives.
The latest Dell PowerEdge R76 0 servers , which use PCIe® 5.0 to connect network devices and storage to the CPU, deliver significant performance improvements over previous generations of PCIe. These improvements can be leveraged in hyperconverged infrastructures running on these servers.
This performance brief provides a comparison of the performance of different generations of server SSDs in a virtualized environment. It compares the new KIOXIA CM7 series NVMe SSDs installed in the new Dell PowerEdge R760 servers with the previous generation KIOXIA CM6 series NVMe SSDs installed in the Dell PowerEdge R740xd in a VMware cluster.
Test 1: IOPS
This test measures the number of input/output operations per second (IOPS) performed by an SSD/server configuration. The results are presented in IOPS. The higher the score for each test, the better.
Test 2: Throughput
This test measured the amount of data transferred to and from the SSD per second. The results are presented in megabytes per second (MB/s). The higher the score for each test, the better.
Test 3: Reading Delay
This test measured the time it took to perform a read operation. It included the average time it took the workload generator to not only perform a read operation, but also the time it took for the operation to complete and receive a "successful completion" acknowledgement. The results are in milliseconds (ms). The lower the score for each, the better. 100% sequential write workloads were not tested for either configuration because they do not involve read operations.
Analysis
The new KIOXIA CM7 NVMe enterprise SSDs installed in the new Dell PowerEdge R760 servers outperformed the previous generation PCIe SSD/server configuration in terms of IOPS, throughput and latency. They also delivered higher performance per watt. The new generation of Dell PowerEdge servers sees significant performance improvements associated with hyperconverged infrastructures that directly impact server, processor, memory and storage performance compared to previous generations.
