15 Virtual SAN (VSAN) is NOT a Virtual Storage Appliance (VSA) Virtual SAN is fully integrated with vsphere (ESXi & vcenter) Drivers embedded in ESXi 5.5 contain the Virtual SAN smarts Kernel modules: Provide the shortest path for I/O Remove unnecessary management overheads when dealing with an appliance Do not consume resources unnecessarily VSA Virtual SAN Not a VSA Virtual SAN Embedded into vsphere 15

16 Virtual SAN: Radically Simple Hypervisor-Converged Storage The Basics vsphere + Virtual SAN Software-defined storage embedded in vsphere Runs on any standard x86 server Pools HDD/flash into a shared datastore SSD Hard disks SSD Hard disks SSD Hard disks Managed through storage policy-based management framework Virtual SAN Shared Datastore High performance through flash acceleration Highly resilient - zero data loss in the event of hardware failures Deeply integrated with the VMware stack 16

17 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 Zero data loss in case of disk, network or host failures vsphere + Virtual SAN Ensures zero downtime from disk or network failures w Interoperable with vsphere HA and Maintenance Mode 17

29 Virtual SAN Use Cases Use Cases for Virtual SAN 5.5 Virtual Desktop (VDI) Tier 2 / Tier 3 / Staging DR Target Site A Site B Handle peak performance requirements (boot, login, read/write storms) VSAN is easy to use and will allow us to scale out a VDI environment using existing hardware without impacting our existing storage environment. Granularly scale from POC to production without huge System upfront Admin, investments OfficeMax Joshua Stark Support high VDI density Rapid storage provisioning and complete automation Virtual SAN s simple storage setup and Ideal ability price/performance to scale make it a compelling technology for our Tier II and Enables III workloads. Cloud Virtual Architect SAN greatly to reduces the complexity in managing storage easily compared provision to a traditional storage SAN or NAS. Harry Le System Admin, Travelocity.com Integrated with vsphere Replication and VMware SRM Virtual SAN allows us to build geographically dispersed clusters in a metro area, allowing a level of redundancy Reduces previously cost of storage not available. More importantly, Virtual SAN provides an unmatched TCO for private cloud infrastructures. Minimizes data center footprint Dave Burns VP of Tech Ops, Cincinnati Bell 29
