Application Performance Analysis on the Synology DS1819+

Performance of SQL Server

Each SQL Server virtual machine has two vDisks: a 100GB boot volume and a 500GB database and log file volume. We used the LSI Logic SAS SCSI controller and configured each VM with 16 vCPUs, 64GB of DRAM, and the LSI Logic SAS SCSI controller. Previously, our Sysbench workloads had overloaded the platform.
