6 Enterprises Adopting vSAN in Production for Tier 1 Apps

US One of the One of the Largest Leader in Large Retailer Largest Airlines Pizza Outlet in the US Social Media

Largest vSAN ROBO deployment Plans to move their entire Tier 1 vSAN is the primary production 1.5PB of streaming video data on (1200 sites) and the largest All Flash apps to HCI (vSAN) and retire all storage deployed on SQL vSAN stored across 100 sites deployment across 32 SAN storage vSAN delivers high storage vSAN All Flash delivered highest vSAN is able to sustain and performance to handle transactional performance on NVMe at the lowest scale both workload performance data on SQL database price (20% cheaper than SAN) and capacity More Customers Enable HCI with VMware HCS than Competition

VMware is, as far as we’re 7,000 + concerned pretty much the most solid approach to Customers choose VMware hyperconvergence. HCS

It really did work as advertised…the fact that I have been able to set it and forget it is huge! VMware vSAN

9 VMware vSAN Radically Simple Hypervisor-Converged Storage for VMs

VM VM VM VM VM VM Overview

• Software-defined storage optimized for VMs vSphere + vSAN • 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
