A team of migration cloud architects are evaluating different storage options for deploying virtual machines...

OCI Block Storage inherently provides better IOPS performance than vSAN for all workload types

OCI Block Storage can be scaled up or down independently of compute resources, unlike vSAN which scales with the cluster

vSAN requires an external network connectivity to synchronize data across hosts, whereas OCI Block Storage does not

vSAN is tightly integrated with VMware's SDDC ecosystem, thus allowing for storage policies to be directly applied to VMs, whereas OCI Block Storage operates as independent block volumes

OCI Block Storage can utilize VMware-specific storage policies for VM provisioning and management, just like vSAN in the OCVS environment
