  2. 2. Virtual SAN Stretch Cluster 2 Enterprise Availability and Data Protection  Stretched Cluster with RPO=0, metro-distance  5 min RPO vSphere Replication  Support for SMP-FT  Support for Oracle RAC  Support for Microsoft Failover Clustering – Increases Enterprise availability and data protection – Deploy Virtual SAN between geographically dispersed locations – Based on an Active–Active architecture – Supported on both Hybrid and All-Flash architectures – Enables synchronous replication of data between sites – Site failure tolerated, with no data loss and near zero downtime Site A Active Site B Active vSphere + Virtual SAN Stretched ClusterHDDSSD HDDSSD HDDSSD HDDSSD HDDSSD HDDSSD
  3. 3. Stretch Cluster Based on vSphere and Virtual SAN Technologies 3 – Stretched Cluster is based on Virtual SAN’s 3 Fault Domain architecture – Functions and managed just like any other Virtual SAN cluster – Witness responsible for quorum and voting mechanism during cluster related failures – the witness is an ESXi virtual appliance – Witness only stores meta-data, no running VMs Fault Domain A Active Fault Domain C Active vSphere + Virtual SAN Stretched Cluster HDDSSD HDDSSD HDDSSD HDDSSD HDDSSD HDDSSD Witness Fault Domain B HDD SSD Enterprise Availability and Data Protection  Stretched Cluster with RPO=0, metro-distance  5 min RPO vSphere Replication  Support for SMP-FT  Support for Oracle RAC  Support for Microsoft Failover Clustering
  4. 4. Virtual SAN Stretch Cluster 4 – Witness appliance can be deployed onto a 3rd site or it can be hosted on vCloud Air – Stretched cluster introduces fault domain/site Read Locality – vSphere enterprise features are seamlessly integrated and supported – vSphere Distributed Resource Scheduler (DRS) – vSphere High Availability (HA) Site A Site B vSphere + Virtual SAN Stretched ClusterHDDSSD HDDSSD HDDSSD HDDSSD HDDSSD HDDSSD < 5 ms latency over >10/20/40 gbps Active Active witness appliance L2 with Multicast Fault Domain A Fault Domain C Fault Domain B Enterprise Availability and Data Protection  Stretched Cluster with RPO=0, metro-distance  5 min RPO vSphere Replication  Support for SMP-FT  Support for Oracle RAC  Support for Microsoft Failover Clustering
  5. 5. Any distance >5 min RPO Enhanced Replication with vSphere Replication and SRM 5 – Replication between Virtual SAN datastores enables RPOs as low as 5 minute – 5 minutes RPO is exclusively available to Virtual SAN 6.x site a vSphere + Virtual SAN Stretched Cluster < 5 ms latency over >10/20/40 gbps Active Active site b L2 with Multicast site x vSphere + Virtual SAN VR DR vCenter vCenter witness appliance SRM SRM Enterprise Availability and Data Protection  Stretched Cluster with RPO=0, metro-distance  5 min RPO vSphere Replication  Support for SMP-FT  Support for Oracle RAC  Support for Microsoft Failover Clustering
  6. 6. Any distance >5 min RPO Virtual SAN Stretch Cluster with vCloud Air Disaster Recovery 6 – vSphere Replication is the replication engine for vCloud Air Disaster Recovery site a vSphere + Virtual SAN Stretched Cluster < 5ms RTT over 10/20/40 gbps Active Active site b L2 with Multicast vCloud Air VR vCenter witness appliance VCD Enterprise Availability and Data Protection  Stretched Cluster with RPO=0, metro-distance  5 min RPO vSphere Replication  Support for SMP-FT  Support for Oracle RAC  Support for Microsoft Failover Clustering
