when we need it. With non-disruptive
scaling we can add capacity or increase
performance at any time without
interrupting our operations.”

Virtual SAN Puts The App In Charge

VM-centric Service Levels for Simpler and Automated Storage Management Through App-centric Approach
1. Define storage
policy
2. Apply policy at
VM creation
✖ Hardware-centric, vendor-
specific management
✖ Slow provisioning, rigid
storage constructs (LUNs,
Volumes)
✖ Data services aligned to
storage container, not directly
with VM needs
✖ Frequent data migrations
 Fast, VM-centric provisioning
 No need to manage LUNs, Vols.
 Resources and data service are
automatically provisioned and
maintained
 Easy to change without data
migration

14. VMware Virtual SAN Architecture
• Each ESX host contributes SSD and magnetic
disk capacity
• Virtual SAN aggregates these resources into one
global Datastore per vSphere cluster
• Each VM home directory and each virtual disk is
represented by a VSAN object
• Virtual machines run on the ESX hosts that belong
to the cluster
• HA/DRS ensures the VM is restarted if a host
crashes
• Virtual SAN objects can be split into multiple
components for performance and data protection.
This is governed by the storage policies.

• Scale up and Scale out architecture – granular and linearly storage, performance and compute
scaling capabilities
– Per magnetic disks – for capacity
– Per flash based device – for performance
– Per disk group – for performance and capacity
– Per node – for compute capacity

17. Technical Characteristics
VMware Virtual SAN

18. Technical Characteristics
Virtual SAN is a cluster level feature similar to:
– vSphere DRS
– vSphere HA
– Virtual SAN
Deployed, configured and manage from vCenter through the vSphere Web Client (ONLY!).
– Radically simple
• Configure VMkernel interface for Virtual SAN
• Enable Virtual SAN by clicking Turn On
18

19. Virtual SAN Implementation Requirements
• Virtual SAN requires:
– Minimum of 3 hosts in a cluster configuration
– All 3 host MUST!!! contribute storage
• vSphere 5.5 U1 or later
– Maximum of 32 hosts (VSAN 5.5)
– Maximum of 64 hosts (VSAN 6.0)
– Locally attached disks
• Magnetic disks (HDD)
• Flash-based devices (SSD)
– Network connectivity
• 1GB Ethernet
• 10GB Ethernet (preferred)

20. Storage Policy-based Management (SPBM)
• SPBM is a storage policy framework built into vSphere that enables virtual machine policy
driven provisioning
• Virtual SAN leverages this new framework in conjunction with VASA API’s to expose storage
characteristics to vCenter:
– Storage capabilities
• Underlying storage surfaces up to vCenter and what it is capable of offering
– Virtual machine storage requirements
• Requirements can only be used against available capabilities
– VM storage policies
• Construct that stores virtual machine’s storage provisioning requirements based on storage capabilities
20

21. Virtual SAN Disk Groups
• Virtual SAN uses the concept of disk groups to pool together flash devices and magnetic disks
as single management constructs.
• In VSAN 5.5, disk groups are composed of at least 1 flash device and 1 magnetic disk.
– Flash devices are use for performance (Read cache + Write buffer).
– Magnetic disks are used for storage capacity.
– Disk groups cannot be created without a flash device.
disk group disk group disk group disk group
Each host: 5 disk groups max. Each disk group: 1 SSD + 1 to 7 HDDs

22. Virtual SAN Objects
• Virtual SAN manages data in the form of flexible data containers called objects. virtual machine
files are referred to as objects.
• Virtual machines files are referred to as objects.
– There are four different types of virtual machine objects:
• VM Home
• VM swap
• VMDK
• Snapshots
• Virtual machine objects are split into multiple
components based on performance and availability
requirements defined in VM Storage
profile.

23. Virtual SAN Components
• Virtual SAN components are chunks of objects distributes across multiple hosts in a cluster in
order to tolerate simultaneous failures and meet performance requirements.
• Virtual SAN utilizes a Distributed RAID architecture to distribute data across the cluster.
• Components are distributed with the use of two
main techniques:
– Striping (RAID0)
– Mirroring (RAID1)
• Number of component replicas and copies created is
based on the object policy definition.

24. Virtual SAN Network
• New Virtual SAN traffic VMkernel interface.
– Dedicated for Virtual SAN intra-cluster communication and data replication.
• Supports both Standard and Distributes vSwitches
– Leverage NIOC for QoS in shared scenarios
• NIC teaming – used for availability and not for bandwidth aggregation.
• Layer 2 Multicast must be enabled on physical switches.
– Much easier to manage and implement than Layer 3 Multicast
