SAP Business One and Public Cloud Services Elastic Cloud Server (ECS) An ECS is an elastically scalable computing server that consists of CPU, memory, images, and EVS disks.
EVS disks cannot be shared across AZs. Therefore, three ECSs are required in the cross-AZ HA scenario. Each ECS is bound to a SCSI disk and iSCSI configuration is required for SBD. Table 1 lists the ECS specifications.
On the page providing details about the ECS, click the EVS tab and locate the disk of the SBD volume. Then, click the target data disk. On the page providing details about the data disk, view and record its mount point. Then, click the data disk ID.
Creating an ECS Based on the deployment scheme, create ECSs with different specifications, such as computing capability, memory, and storage. The following describes how to create an ECS. Procedure Log in to the management console, click Service List and choose Computing > Elastic
