• Separate storage controllers with their own OS to manage
• All storage I/O traverse multiple hardware / software layers
• Minimal management & policy integration with hypervisor
• Scaling requires “shelf” or controller purchase
Traditional SAN/NAS Approach

• Separate storage virtual appliances with their own OS to manage
• All storage I/O traverse multiple software layers
• Lack networking and security virtualization
• Lack management & policy integration with hypervisor

VM submits a read request to VSAN datastore object
VSAN synchronously submits read request to ESXi hosts
ESXi hosts submit read request to cache tier (hybrid) and capacity tier
Cache / capacity tier return data to ESXi host(s)
ESXi host(s) return data to VSAN datastore object
VSAN datastore returns data to VM
VM submits data to be written to the VSAN datastore object
VSAN synchronously submits data to be written to ESXi hosts
ESXi hosts write data to cache tier

Secure Data with vSAN Data-at-Rest Encryption
• Datastore level, data-at-rest encryption for all objects on vSAN Datastore
• Enabled at cluster level, supporting hybrid, all-flash, and stretched clusters
• No need for self encrypting drives (SEDs), reducing cost and complexity
• Works with all vSAN features, including deduplication and compression
• Integrates with KMIP compliant key management technologies, including SafeNet, Hytrust, Thales, Vormetric, etc.
vSphere vSAN

Increase Flexibilitywith Site Affinity for Stretched Clusters
vSphere vSAN
ClusterCluster
• User can specify single site location of VM’s components if site level protection is unnecessary
• Policy driven using SPBM
• Reduces network and storage requirements
• Ideal for solutions that already use application redundancy (Exchange DAGs, SQL Availability groups, etc.)

Witness
• Easy replacement of witness host in stretched cluster environments
• Reduces potential time stretched cluster configuration may be without a witness
• UI driven. Eliminates need for manual steps or scripting
Simplified, Cloud-friendly Networking with Unicast
• Multicast no longer used
• Easier configurations for single site and stretched clusters
• vSAN changes over to unicast when cluster upgrade to 6.6 completes
• No compromises in CPU utilization
• Little effect on network traffic when using unicast over multicast
