•Introduction to VSAN
•VSAN Architecture
•Configuring VSAN –Demo (Off-Line Demo)
•Additional Resources
•Q & A
•What’s in your vSphere environment?
3. The Hypervisor Opens Up New Opportunities
3
SAN / NAS
x86 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 the HCL: http://www.vmware.com/resources/compatibility/search. php?deviceCategory=vsan
5. 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 vmkConfigured on Each Host
•Supports Virtual Distributed Switch Network I/O Control
•L2 Multicast required on VSAN Network, recommend Jumbo Frames and 10GB
6. VSAN Architecture Contd.
8
•Full integration with HA, DRS, Horizon View (including Linked Clones), and SRM
•Storage Policies assigned at the VM (Storage Policy Based Management)
•vCenterand ESXihosts running 5.5 U1
•Managed with vSphereWeb 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 datastoreper cluster and thin-provisioning is enforced by default
•Does Not Support Storage I/O Control, DatastoreClusters
•VSAN Uses Includes: Management Cluster, DMZ, Remote Office, VDI, DR, Tier 2/3, Test & Dev
7. Two Ways to Build a Virtual SAN Node
9
Completely Hardware Independent1. 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 …
SSDor PCIe
SAS/NL-SAS/ SATA HDDs
Any Server on vSphere Hardware Compatibility List
HBA/RAID Controller
10. vSphere + Virtual SAN
12
Simpleto set up via policy
Delivered on per VMbasis
Zero data loss in case of disk, network or host failures
Ensureszero downtimefrom disk or networkfailures
Interoperable with vSphere HA and Maintenance Mode
Virtual SAN Is Highly Resilient Against Any Hardware Failure
Virtual SAN is Designed to Ensure Data is Never Lost in Case of Failures
11. Virtual Machine Storage Policies
•Storage Capabilities assigned to Storage Policies
•VASA (Storage API’s Storage Awareness) used to show Vendor Storage Capabilities
•Storage Policies assigned to the VM’s
•Storage Policy can be changed while the VM is running
12. Scale UP
Add more Disks
IOPS
Capacity
40 TB
400 TB
4.4 PB
Scale OUT
Add more nodes
ElasticGrow or shrink on demand
GranularAdd single nodes or disks
Non-disruptive No app downtime
VSAN Enables Elastic Linear Scalingof Performance and Capacity
Ability 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.”
