• Critical services converged in
hypervisor kernel
• Minimal software for reliability
• Direct I/O path from VMs to hardware
• No physical or virtual appliances to
manage
• Tight management & policy integration
• Easy scale-up & scale-out

19. Two clicks to deploy!
vSAN Simplifies Storage
If You know vSphere, You know vSAN, You know SDDC

20. Define a policy first…
Virtual SAN currently surfaces multiple storage capabilitiesto vCenterServer
WhatIf APIs

21. Assign it to a new or existing VM, or vmdk
• When the policy is selected, vSAN
uses it to place/distribute the VM
to guarantee availability and
Performance
• Policies can be changed without
any interruption to the VM

22. 25©2018 VMw are, Inc.
Deliver Performance and Protection Based on Application Needs
• Define storage protection
and performance levels per
VM or per VMDK
• Managed in hypervisor

• Virtual SAN cluster split across 2 sites!
• Site-level protection with zero data loss
and near-instantaneous recovery
• Support for up to 5ms RTT latency
between data sites
– 10Gbps bandwidth expectation
• Witness VM can reside anywhere
– 200ms RTT latency
– 100Mbps bandwidth required at most
• Automated failover
• Requires vSAN Enterprise license
