Data center infrastructures are generally divided into three categories: traditional, converged, and hyperconverged. Hyperconverged infrastructures allow users to add computing resources, memory and storage as needed, providing the flexibility to scale horizontally and vertically. However, many virtual machine (VM) configurations run in converged infrastructures, and their ability to scale is often hampered when VM clusters require more memory.
VMware®, Inc. provides hyperconverged infrastructures using VMware ESXi™ and VMware vSAN™ platforms. The VMware ESXi platform is a popular enterprise-grade virtualization platform that allows you to scale computing resources and memory as needed and provides easy management of large clusters of virtual machines. The VMware vSAN platform allows you to move from a converged to a hyperconverged infrastructure, providing incredibly high performance because the 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 for more efficient use of NVMe solid-state drives.
The latest Dell PowerEdge R76 0 servers , which use the PCIe® 5.0 interface to connect network devices and storage systems to the central processing unit, significantly improve data transfer performance compared to previous generations of PCIe. These improvements can be used in hyperconverged infrastructures running on these servers.
This performance overview compares the performance of different generations of SSD servers in a virtualized environment. It compares the new KIOXIA CM7 series NVMe SSDs installed in the new Dell PowerEdge R760 servers and the previous generation KIOXIA CM6 NVMe series 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 the SSD/server configuration. The results are presented in IOPS. The higher the score for each test, the better.
Test 2: Bandwidth
This test measured the amount of data transferred per second to and from the SSD. The results are presented in megabytes per second (MB/s). The higher the score for each test, the better.
Test 3: Delayed reading
This test measured the time required to perform a read operation. It included the average time it took for the load generator not only to complete a read operation, but also the time it took to complete the operation and receive a "completed successfully" confirmation. Results are given in milliseconds (ms). The lower the result for each of them, the better. 100% sequential write workloads for both configurations were not tested because they do not include read operations.
Analysis
The new KIOXIA CM7 NVMe series enterprise solid-state drives installed in the new Dell PowerEdge R760 servers have surpassed the previous configuration of PCIe generation solid-state drives/servers in terms of IOPS, throughput and latency. They also provided higher performance per watt. The new generation of Dell PowerEdge servers see significant performance improvements associated with hyperconverged infrastructures that directly impact server, processor, memory and storage performance compared to previous generations.
