EVS disks cannot be shared across AZs. For details about how to create and configure a shared disk in a cross-AZ HA scenario, see Configuring iSCSI (Cross-AZ HA Deployment).
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.
The SAP HANA snapshot technology is used to back up data of multiple EVS disks contained in ECSs to the OBS. Storage snapshots cannot ensure file system consistency. The CSBS Agent integrates the SAP HANA snapshot function to ensure file system consistency.

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.
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. SAP NetWeaver and SAP HANA can be deployed on the same ECS. 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.
