Virtual SAN Is Hypervisor-converged
Virtual SAN is embedded in the vSphere
Kernel
•Consumes <10% CPU
Simple to manage
•No need to
install and
manage
separate virtual
appliances
•No single point
of failure
•Provides the
shortest path
for I/O

Overview
•No File System
•
ESX manages array through VASA
(vSphere APIs for storage awareness) APIs
•
Arrays are logically partitioned into
containers, called Storage Containers
•
VM disks, called Virtual Volumes, stored
natively on the Storage Containers.
•
IO from ESX to array is addressed through
an access point called Protocol Endpoint
(PE)
•
Data services are offloaded to the array
•
Managed through storage policy-based
management framework

vSphere 6.0 - Storage Container (SC)
What are Storage Containers?
•
Logical storage constructs for grouping of
virtual volumes.
•
Setup by storage administrators
•
Capacity is based on physical storage
capacity
•
Logically partition or VM isolation with
diverse storage needs and requirement
•
Minimum one storage container per
array
•
Maximum depends on the array
•
A single SC can be simultaneously
accessed via multiple Protocol
Endpoints
