In the Admin Panel you can change type of SCSI controller from default LSI SAS to PVSCSI (Paravirtual SCSI). An instance should be turned off while changing this option otherwise user will be asked to restart it. PVSCSI and LSI Logic Parallel/SAS are essentially the same when it comes to overall performance capability. PVSCSI, however, is more efficient in the number of host compute cycles that are required to process the same number of IOPS. It means that if you have a very storage IO intensiv...

In order to ensure high-availability of database we will use a highly available cluster, consisting of two nodes. Data replication between nodes will be held at the block level using DRBD software. To increase the reliability of the proposed solution, we can create nodes in different sub-regions to work in physically separate pools of resources. To learn more about the subregions, click here [1]. 1. ASSUMPTIONS We will use template with Ubuntu Server, for each of the two instances created...
