• Introduction to VSAN
• VSAN Architecture
• Configuring VSAN – Demo (Off-Line Demo)
• Additional Resources
• Q & A
• What’s in your vSphere environment?
The Hypervisor Opens Up New Opportunities

SAN / NASx86 Servers Cloud Storage
vSphere
The virtualization platform:
• Knows the needs of all
apps in real time
• Sits directly in the I/O path
• Global view of underlying
infrastructure
• Software Defined Storage
• Hardware agnostic- Check

VSAN Is Not an Appliance
VSAN Architecture
• SSD used for Read Cache & Write
Buffer Cache
• HDD stores VMDK, VM namespace
directory, vswap, Delta disks
created for snapshots
• VSAN IP Network used for Storage
Replication & Connectivity
• A vmk Configured on Each Host
• Supports Virtual Distributed Switch
Network I/O Control
• L2 Multicast required on VSAN
Network, recommend Jumbo
Frames and 10GB
VSAN Architecture Contd.

• Full integration with HA, DRS, Horizon View (including Linked Clones), and SRM
• Storage Policies assigned at the VM (Storage Policy Based Management)
• vCenter and ESXi hosts running 5.5 U1
• Managed with vSphere Web Client
• Minimum of 3 hosts with minimum 1 SSD and 1 HDD
• If more than 3 hosts are in the cluster then not all hosts need to contribute storage
• Maximum of 32 hosts per cluster, 32,00 VM’s, 5 disk groups per host, each disk group
has maximum of 7 HDD and 1 SSD
• Object-based storage with VMFS-L file system
• Single VSAN datastore per cluster and thin-provisioning is enforced by default
• Does Not Support Storage I/O Control, Datastore Clusters
• VSAN Uses Includes: Management Cluster, DMZ, Remote Office, VDI, DR, Tier 2/3, Test

Two Ways to Build a Virtual SAN Node
9
Completely Hardware Independent
1. Virtual SAN Ready Node
…with multiple options available at GA + 30
Preconfigured server ready to use Virtual SAN…
2. Build Your Own
…using the Virtual SAN Compatibility Guide*
Choose individual components …
SSD or PCIe
SAS/NL-SAS/ SATA HDDs
Any Server on vSphere

vSphere + Virtual SAN

Simple to set up via policy
Delivered on per VM basis
Zero data loss in case of disk, network or host failures
Ensures zero downtime from disk or network failures
Interoperable with vSphere HA and Maintenance Mode
Virtual SAN Is Highly Resilient Against Any Hardware FailureVirtual SAN is Designed to Ensure Data is Never Lost in Case of Failures
Virtual Machine Storage Policies

VSAN Enables Elastic Linear Scalingof Performance and CapacityAbility to Expand Storage by Adding Hosts & Disks
“Virtual SAN enables us to scale our
storage infrastructure and while
providing the necessary redundancy.
This allows us to be more agile and
bring our solutions to market faster.”
