VMware Virtual SAN Performance Testing – Part IV

posted

In Part I, Part II and Part III of this blog post series, we reviewed methods of running benchmark tests on a Virtual SAN cluster using three different methods; synthetic I/O Tools such is Iometer, pre-created application I/O trace replay files available for download, or custom created application I/O trace replay. Once you are running Read more...

VMware Virtual SAN Performance Testing – Part III

posted

In the previous VMware Virtual SAN Performance Testing blog post we reviewed the benefits of running performance tests utilizing I/O trace files over synthetic workload tools such as IOmeter to more accurately characterize the performance of a Virtual SAN cluster. The VMware I/O Analyzer includes pre-created trace files of specific application profiles that allows you Read more...

VMware Virtual SAN Performance Testing – Part II

posted

In the first installment of the Virtual SAN Performance Testing series, we reviewed benchmarking performance using synthetic I/O generation tool Iometer, automated by the VMware I/O Analyzer appliance. Using Iometer, or other synthetic I/O generation tools is frequently the first option for benchmarking selected, as it is an operationally light weight method to benchmark storage Read more...

co-author Bhumik Patel,  VMware Partner Architect  As customers look to implement Virtual SAN in their environments, it is critical that the underlying platform has the matching attributes of rapid provisioning, unified management, linear scalability and operational simplicity to be able to fully leverage the capabilities of a scale-out, hypervisor-converged Virtual SAN solution. With Cisco UCS Read more...

VMware Virtual SAN and Block Alignment

posted

Recently a question came up around Virtual SAN and block alignment that I want to address. Traditionally, there have been two potential block alignment issues in vSphere environments: 1) VMFS block alignment with respect to underlying array chunks. Alignment at the VMFS layer has been addressed since VMFS-3 (used in vSphere 3 and 4) being Read more...
