VMware Virtual SAN Review: SQL Server Performance

Continuing on the path of VMware VSAN performance testing, the next test looks at Microsoft SQL Server TPC-C running across the cluster. This test uses SQL Server 2014 running on Windows Server 2012 R2 guest VMs, being stressed by Dell's Benchmark Factory for Databases. While our traditional usage of this benchmark has been to test large 3,000-scale databases on local or shared storage, in this iteration we focus on spreading out four 1,500-scale databases evenly across our VSAN cluster to better illustrate the aggregate performance of the 4-node cluster.

VMware Virtual SAN Review: Sysbench OLTP Performance

To measure the performance of the VMware VSAN cluster in transactional database workloads, we first leverage the Sysbench OLTP benchmark, paying close attention to total aggregate performance. The Sysbench OLTP benchmark runs on top of Percona MySQL leveraging the InnoDB storage engine operating inside a CentOS installation. While a traditional SAN infrastructure can better cope with large single workloads, hyper-converged systems are designed to spread that load across all nodes in the system. To that end, we deployed four Sysbench VMs on the VSAN cluster, 1 per node, and measured the total performance seen on the cluster with all operating simultaneously.

VMware Virtual SAN Review: VMmark Performance

Tuning hyper-converged systems for VMmark presents new challenges for how StorageReview runs the benchmark. Our VMmark implementation is designed for traditional IT architectures, fixed compute servers and review storage hardware swapped between tests. With VMware VSAN, storage and compute are merged into one platform with one single datastore, necessitating a modification to our VMmark setup. In this case we had our VMware VSAN cluster both running the storage and the compute requirements, offering a one-two punch compared to traditional platforms that would require compute servers separate.

VMware Virtual SAN Review: Overview and Configuration

VMware Virtual SAN (VSAN) is part of the burgeoning category of software defined everything that's assaulting all points from corporate datacenters to remote and branch offices. VMware describes VSAN as "hypervisor-converged storage" that is optimized for vSphere virtual infrastructure. However you refer to this space, the mission is more or less the same; to greatly simplify enterprise IT, reduce total cost of ownership and provide flexible scalability while delivering predictable performance. The path vendors take to achieve these quad-objectives is widely varied however. For their part VMware has a singular focus, to deliver against these goals in the most comprehensive, cost effective way for organizations using vSphere.
