1. VVOLs & vSphere 6 STO3161 Matt Cowger
2. vSphere 6 New Features • Fault Tolerance for SMP • 4vCPUS • Long Distance vMotion • 100ms • “Content Library” • fully replicated • Higher Scale • VVOLs • Platform Services • Certificate Mgmt, Licensing, SSO, Root CA, etc. • Larger Clusters • 64 hosts 2 • VSAN 2.0 • All flash configs • Larger clusters (64) • Virsto-based snapshots
3. CONFIDENTIAL Today’s Challenges in External Storage Architectures 3 External Storage vSphere Array-a Array-b Today 1. Create fixed-size, uniform LUNs 2. Lack of granular control 3. Complex Provisioning cycles 4. LUN centric storage configurations ✖ Extensive manual bookkeeping to match VMs to LUNs ✖ LUN-granularity hinders per-VM SLAs ✖ Overprovisioning (better safe than sorry!) ✖ Wasted resources, wasted time, high costs ✖ Frequent Data Migrations LUN LUN LUN LUN LUN
4. CONFIDENTIAL VMware Software-Defined Storage and Virtual Volumes 4 Policy-driven Control Plane Virtual Data Plane Virtual Datastores Performance Mobility Data Protection Virtual Data Services Cloud Object Storage SAN / NAS x86 Servers • Interface between apps and storage services • Interprets VM-policies and composes service • Initial placement and on-going optimization • Abstraction and pooling = Storage container • HW capabilities expressed to control plane • New storage tiers for data persistency • Applied to individual VMs • Dynamically invoked by control plane • Array-based, 3rd party VA Virtual Volumes
5. CONFIDENTIAL Virtual Volumes: Architecture Significant Changes vSphere Block I/F VMFS Block Storage Array Metadata Operations create, delete, etc. Data Operations Read/Write (name, offset) VMFS File Lifecycle Operations LUN SAN I/O 2 I/O VASA
 Provider File I/F 1 1 Out-of-band Lifecycle operations between ESXi and VASA Provider. Create, Delete, etc. 2 VASA Provider handles Virtual Volumes namespace and mapping for Array 3 3 Virtual Volume presented for Block or File I/O Logically part of the Array. May or may not be physically part of array. Must be HA. Based on vSphere 5 VASA interface
 for storage awareness/management Same structure for NFS,
 including out-of-band protocol Minor I/O
 Impacts Management
 Changes Completely New Protocol 5
6. CONFIDENTIAL High Level Architecture 6 Overview • No FileSystem • 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 vSphere Storage Policy-Based Mgmt. Virtual Volumes PE VASA Provider
