• 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

• Scaling requires expensive node purchase

• 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
