Proč je vSAN č. 1 v software defined storage a HCI

  1. 1. ©2018 VMware, Inc. VMware and HCI vSAN Software Defined Storage Senior Systems Engineer October 2018 Pavel Kovář
  2. 2. Complex and Separate Silos Servers and Blades External Storage Networking Hardware Limitations of Traditional 3-Tiered Architecture 2
  3. 3. Modernization of the Data Center Being Fueled by HCI 3-Tiered Architecture Built on proprietary hardware Virtualization Compute Storage Networking Storage Greater agility and scale Lower total costs Simplified management Built on industry-standard servers and components Hyper-Converged Infrastructure Virtualization, Compute, Storage and Networking
  4. 4. Fundamental system design shift with HCI Storage Servers Converged SAN Hyper-Converged
  5. 5. Fundamental system design shift with HCI Fast network Scale-out Scale-out Software-defined storage
  6. 6. HCI is the Fastest Growing Storage Segment Hyperscale HCI and Server SAN Traditional Storage 2012 2026 2015 2016 2017 2018 2019 2020 2021 $10.7 B $4.4B $2.8B $1.5B $0.5B 0 $10B $20B $30B $40B $50B Total Storage Market Source: Gartner Forecast Analysis: Integrated Systems Worldw ide, 1Q17 UpdateSource: Wikibon Server SANResearch Project, 2016 $60B $8.7B Hyper-Converged Infrastructure $6.4B

VMware HCI 9 • Critical services converged in hypervisor kernel • Minimal software for reliability • Direct I/O path from VMs to hardware • No physical or virtual appliances to manage • Tight management & policy integration • Easy scale-up & scale-out vSphere Compute – vSphere Storage – vSAN Networking & Security – NSX The Key Difference: One Software Platform

  16. 16. vSphere vSAN The vSAN difference – Scale UP and OUT vSphere vSAN • Add capacity the way you want • Scale UP by adding drives • Scale OUT by adding hostsvSphere vSAN Compute Utilization
  17. 17. Tiered Hybrid vs All-Flash All-Flash 150K IOPS per Host + sub-millisecond latency Caching Writes cached first, Reads from capacity tier Capacity Tier Flash Devices Reads go directly to capacity tier SSD PCIe Data Persistence Hybrid 40K IOPS per Host Read and Write Cache Capacity Tier SAS / NL-SAS / SATA SSD PCIe Ultra DIMM Virtual SAN NVMe

  19. 19. Two clicks to deploy! vSAN Simplifies Storage If You know vSphere, You know vSAN, You know SDDC
  20. 20. Define a policy first… Virtual SAN currently surfaces multiple storage capabilitiesto vCenterServer WhatIf APIs
  21. 21. Assign it to a new or existing VM, or vmdk • When the policy is selected, vSAN uses it to place/distribute the VM to guarantee availability and Performance • Policies can be changed without any interruption to the VM
