Description:

In VMware vSphere 6.0, snapshots with VMware vSAN have been completely redesigned. In this paper, we present the performance of vSAN snapshots for two different applications, namely a source tree compilation workload to roughly mimic "test and development" scenarios, and an online transaction-based database application. Overall, we find that vSAN snapshots in vSphere 6.0 perform reasonably with minimal performance degradation compared to base disk performance. We also address performance tunable configurations and sizing recommendations to optimize performance with vSAN. snapshots.
