Frans Van Rooyen Cloud Architect, Adobe 10

11 Virtual SAN Delivers Enterprise-Grade Scale Maximum Scalability per Virtual SAN Cluster 32 Hosts 2M IOPS 3,200 VMs 4.4 Petabytes Virtual SAN allows us to build out scalable heterogeneous storage infrastructure like the Facebooks and Googles of the world. Virtual SAN allows us to add scale, add resources, while being able to service high performance workloads. Dave Burns VP of Tech Ops, Cincinnati Bell 11

12 Virtual SAN Puts The App In Charge Simpler and Automated Storage Management Through Application-centric Approach Today Today Virtual SAN 1. Pre-define storage configurations 2. Pre-allocate static bins 3. Expose pre-allocated bins 4. Select appropriate bin 5. Consume from pre-allocated bin Overprovisioning (Better safe than sorry!) Wasted resources, wasted time Frequent data migrations Virtual SAN Shared Datastore 1. Define storage policy 2. Apply policy at VM creation Resource and data service are automatically provisioned and maintained. No overprovisioning Less resources, less time Easy to change 12

13 Virtual SAN Simplifies And Automates Storage Management Per VM Storage Service Levels From a Single Self-tuning Datastore Per VM Storage Policies Policies Set Based on Application Needs Software Automates Control of Service Levels Capacity Storage Policy-Based Management Performance vsphere + Virtual SAN SLAs Availability Virtual SAN Shared Datastore No more LUNs/Volumes! 13

14 Virtual SAN Is Highly Resilient Against Any Hardware Failure Virtual SAN is Designed to Ensure Data is Never Lost in Case of Failures Simple to set up via policy Delivered on per VM basis vsphere + Virtual SAN 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 14

16 Virtual SAN Requirements

17 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 Locally attached disks Magnetic disks (HDD) Flash-based devices (SSD) vsphere 5.5 U1 Cluster local storage local storage local storage HDD HDD HDD cluster Network connectivity esxi-01 esxi-02 esxi-03 1GB Ethernet 10GB Ethernet (preferred) VSAN License. Per CPU / per user (VDI) 17

18 Two Ways to Build a Virtual SAN Node Completely Hardware Independent 1. Virtual SAN Ready Node Preconfigured server ready to use Virtual SAN 2. Build Your Own Choose individual components Any Server on vsphere Hardware Compatibility List SSD or PCIe SAS/NL-SAS/ SATA HDDs HBA/RAID Controller with multiple options available at GA + 30 using the Virtual SAN Compatibility Guide* Note: For additional details, please refer to Virtual SAN VMware Compatibility Guide Page Components for Virtual SAN must be chosen from Virtual SAN HCL, using any other components is unsupported 18

23 Configuring VMware Virtual SAN Radically Simple configuration procedure Setup Virtual SAN Network Enable Virtual SAN on the Cluster Select Manual or Automatic If Manual, create disk groups 23

24 Configure Network Configure the new dedicated Virtual SAN network vsphere Web Client network template configuration feature. 24

25 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 uplink1 uplink2 vmk0 Management Virtual Machines vmotion Virtual SAN 20 shares 30 shares 50 shares 100 shares Distributed Switch vmk1 vmk2 19

26 Enable Virtual SAN One click away!!! Virtual SAN configured in Automatic mode, all empty local disks are claimed by Virtual SAN for the creation of the distributed vsandatastore. Virtual SAN configured in Manual mode, the administrator must manually select disks to add the the distributed vsandatastore by creating Disk Groups. 26

27 Virtual SAN Disk Groups Virtual SAN uses the concept of disk groups to pool together flash devices and magnetic disks as single management constructs. 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. Each host: 5 disk groups max. Each disk group: 1 SSD + 1 to 7 HDDs disk group disk group disk group disk group disk group HDD HDD HDD HDD HDD 15

28 Virtual SAN Datastore A single Virtual SAN Datastore is created and mounted, using storage from all multiple hosts and disk groups in the cluster. Virtual SAN Datastore is automatically presented to all hosts in the cluster. Virtual SAN Datastore enforces thin-provisioning storage allocation by default. 28

29 VM Storage Policies VM Storage Policies are accessible from vsphere Web Client Home screen. 29

30 Virtual SAN Capabilities Virtual SAN currently surfaces five unique storage capabilities to vcenter. 30

31 Number of Failures to Tolerate Number of failures to tolerate. Defines the number of hosts, disk or network failures a storage object can tolerate. For n failures tolerated, n+1 copies of the object are created and 2n+1 host contributing storage are required. esxi-01 esxi-02 esxi-03 esxi-04 Use case: Redundancy raid-1 vsan network vmdk vmdk ~50% of I/O ~50% of I/O witness Virtual SAN Policy: Number of failures to tolerate = 1 31

32 Number of Disk Stripes Per Object Number of disk stripes per object The number of HDDs across which each replica of a storage object is distributed. Higher values may result in better performance. esxi-01 esxi-02 esxi-03 esxi-04 Use case: Performance vsan network raid-0 raid-1 raid-0 stripe-1a stripe-1b stripe-2a stripe-2b witness VSAN Policy: Number of failures to tolerate = 1 + Stripe Width =2 32

33 Virtual SAN Storage Capabilities Flash read cache reservation (%). Flash capacity reserved as read cache for the storage object. Specified as a percentage of logical size of the object. Use case: Performance Object space reservation (%). Percentage of the logical size of the storage object that will be reserved (thick provisioned) upon VM provisioning. The rest of the storage object is thin provisioned. Use case: Thick provisioning Force provisioning. Use case: override policy if yes, the object will be provisioned even is the policy specified in the storage policy is not satisfiable with the resources currently available. Use case: override policy 33

34 Virtual Machine Provisioning Operations If the VSAN Datastore can satisfy the VM Storage Policy, the VM Summary tab will display the VM as compliant. If not, due to failures, or the force provisioning capability, the VM will be shown as non-compliant. 34

35 Magnetic Disk Failure Instant mirror copy Degraded - All impacted components on the failed disk will be instantaneously created onto other disk, disk groups, or hosts. Disk failure, instant mirror copy of impacted component esxi-01 esxi-02 esxi-03 esxi-04 vsan network raid-1 vmdk vmdk X vmdk witness Instant! new mirror copy

36 Host Failure 60 Minute Delay Absent will wait the default time setting of 60 minutes before starting the copy of objects and components onto other disk, disk groups, or hosts. Greater impact on the cluster overall compute and storage capacity. Host failure, 60 minutes wait copy of impacted component esxi-01 esxi-02 esxi-03 esxi-04 vsan network raid-1 X vmdk vmdk vmdk witness 60 minute wait new mirror copy
