3 VMware Virtual SAN 6.0 Radically Simple Hypervisor-Converged Storage for VMs Overview SSD vsphere + Virtual SAN Hard disks SSD SSD Hard disks Hard disks Software-defined storage optimized for VMs Hypervisor-converged architecture Runs on any standard x86 server Pools HDD/SSD into a shared datastore Delivers enterprise-level scalability and performance Managed through per-vm storage policies Deeply integrated with the VMware stack Virtual SAN Datastore

4 Virtual SAN Is Hypervisor-converged Virtual Storage Appliance Virtual SAN is embedded in the vsphere Kernel Consumes <10% CPU Virtual SAN is Embedded inside VM Kernel vsphere... Simple to manage No need to install and manage separate virtual appliances No single point of failure Provides the shortest path for I/O Seamless integration with vsphere and VMware stack

5 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 Performance Storage Policy-Based Management vsphere + Virtual SAN SLAs Availability Virtual SAN Shared Datastore No more LUNs/Volumes!

6 What s New in Virtual SAN 6.0 All Flash Architecture 4x Performance 2x Scale Enterprise Data Services Broader Hardware Support Data persistence on SSD Intelligent caching and two-tier architecture 90K IOPS/host (4.5x more) Scale to 64 nodes (2x more) 200 VMs/host (2x more) 62 TB max. virtual disk size New high performance snapshots & clones Rack awareness to tolerate rack failures HW-based checksum & encryption Expand scalability for blades with direct-attached JBODs Expanded HCL and more ready nodes

7 Virtual SAN Can Be Deployed With A Tiered Hybrid Or All-Flash Architecture Hybrid All-Flash New! SSD PCIe Ultra DIMM Caching SSD PCIe Ultra DIMM Read and Write Cache Writes cached first, Reads go direct to capacity tier Virtual SAN Capacity Tier SAS/NL SAS/SATA/Direct-attached JBOD Data Persistence Capacity Tier Flash Devices Reads go directly to capacity tier 40K IOPS per Host 90K IOPS per Host + sub-millisecond latency

8 Virtual SAN 6.0 Now Ready For Business-Critical Apps Virtual Infrastructure Best storage for VMs Optimized for Virtual Infrastructure Enterprise-class Business Critical Apps VDI DR Test/Dev Ready for business critical apps

9 Why Customers Love Virtual SAN? Radically Simple High, Predictable Performance with Elastic Scalability Lower TCO Two click install Single pane of glass Policy-driven Self-tuning Integrated with VMware stack Flash-acceleration and SSD persistence Consistent IOPS with submillisecond response times Linear, non-disruptive scaling Embedded in vsphere kernel Server-side economics No large upfront investments Grow-as-you-go Easy to operate with powerful automation No specialized skillset needed

11 vsphere Virtual Volumes Management & Integration Framework for External Storage Virtual Volumes Overview Virtualizes SAN and NAS devices Virtual disks are natively represented on arrays Enables finer control with VM level storage operations using array-based data services Storage Policy-Based Management enables automated consumption at scale Supports existing storage I/O protocols (FC, iscsi, NFS) Industry-wide initiative supported by major storage vendors Included with vsphere

12 vsphere 6.0 -VMware Virtual Virtual Volumes VI admin Ability to express application (VM/VMDK) granular data services Provide easy on-demand Capacity provisioning Compliance Monitoring Ability to get most out of the storage system Storage admin Easy Capacity management Meet VM SLOs Access Control and Security

13 vsphere Virtual Volumes Architecture Storage Policy-Based Mgmt One-to-one mapping of Storage Container to VVOL Datastore VVOL Datastore Control Path Data path leverages existing storage I/O protocols Data Path NFS, iscsi, FC Protocol Endpoint Storage Container Control Path Vendor Provider (VASA) Out of band communication using VASA VVOL-enabled array

14 vsphere 6.0 Virtual Volumes External Storage Architectures Without Virtual Volumes With Virtual Volumes vsphere datastore a vsphere Provides Per-VM Granularity Offloaded Data Services Policy based Management AND LUN LUN LUN LUN LUN Eliminates LUN Management Array-a Array-b Replication Snapshots Caching Encryption De-duplication 1

15 vsphere High Level Storage Architecture Storage Policy Overview Storage Policy-Based Mgmt. vsphere Virtual Volumes PE PE VASA Provider Capacity Performance Availability Data Protection Security 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 Published Capabilities Snapshot Replication Deduplication Encryption 16

16 vsphere Storage Container (SC) SC vcenter Virtual Volumes 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

17 vsphere Storage Container (SC) Do I still need to create Datastores? vsphere Datastore Storage Container

18 vsphere Storage Policy Based Management (SPBM) Array Capabilities Storage Policy-Based Mgmt. Virtual Volumes APIs Disk Types Disk Encryption Dedupe CV Replication Snapshot CV CV Publish Capabilities Array based features and data services Defines what an Array can offer Advertised to ESX through VASA APIs Storage admin
