Configuration 4: VMware stretched cluster using VPLEX Notes • SRM does not support vApps. We had to change the vApp to a resource pool and define a custom startup procedure to fully support the solution. • SRM requires a specific Storage Replication Adapter (SRA) to work with MirrorView. Testing environment VMware stretched clusters allow you to expand the capabilities of a localized vSphere cluster to include ESXi nodes on separate sites. This includes the ability to vMotion virtual machines and storage across sites. It also allows for HA and DRS across sites. This is made possible by two-way storage replication, stretched networks, and a single vCenter instance for both sites. For our purposes, we used EMC VPLEX with distributed storage groups to handle the two-way data replication between the sites. The network from the primary site was made available (stretched) to all the nodes on the secondary site. The VPLEX data replication was handled via IP over two 10 Gb optical Ethernet links. The following figure shows this testing environment. Figure 4: VMware Stretched cluster using VPLEX Quantifying Performance of Sectra PACS with EMC VNX Storage Technologies 15 Reference Architecture
