  11. The Evolution of VMware-powered HCI Deployment Options

  12. VMware-powered HCI Service Offerings

  13. More Customers Enable HCI with VMware HCS than Competition 3,000+ Customers choose VMware HCS “ “ In my experience VMware solutions are rock solid…we’re ready to nearly double our Virtual SAN deployment. It really did work as advertised…the fact that I have been able to set it and forget it is huge! ” ”

  14. Why VMware Hyper-Converged Software? Radically Simple Highest Performance Lowest Cost Any App,Any Scale 1 >100K 50% >6M $ Integrated SW stack IOPS per node Lower TCO IOPS per cluster >100 <1ms $1/GB 1 Pre-Certified Ready Nodes to Match Existing Infrastructure Latency with all-flash systems As low as $1 per usable GB of all-flash Virtual SAN Platform for business critical apps, Openstack and containers

  15. Virtual SAN Enables a Radically Simple HCI Solution

  16. VMware Virtual SAN Radically Simple Hypervisor-Converged Storage for VMs Overview • 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 VM VM VM VM VM VM vSphere + Virtual SAN … Virtual SAN Datastore

  17. VMware Virtual SAN 6.2 Ready For All vSphere Workloads Best storage for VMs Business Critical Apps DR / DA Optimized for vSphere Management ROBO DMZ Staging Enterprise-class resiliency VMware vSphere + Virtual SAN Business critical app ready Test/Dev End User Computing

  18. Tiered All-Flash and Hybrid Options All-Flash Hybrid Caching NVMe NVMe SSD SSD PCIe PCIe Writes cached first, Reads from capacity tier Read and Write Cache Data Persistence Virtual SAN Capacity Tier Flash Devices Reads primarily from capacity tier Capacity Tier SAS / NL-SAS / SATA 100K IOPS per Host + sub-millisecond latency 40K IOPS per Host

  19. Virtual SAN Enables the Lowest Cost HCI Solution

  20. Beta All Flash Only Deduplication and Compression for Space Efficiency • Nearline deduplication and compression per disk group level. • Will be called “Space Efficiency” • Space Efficiency enabled on a cluster level • Deduplicated when de-staging from cache tier to capacity tier • Fixed block length deduplication (4KB Blocks) • Compressed after deduplication esxi-01 esxi-02 esxi-03 vSphere & Virtual SAN vmdk vmdk vmdk

  21. All Flash Only RAID-5 Erasure Coding • With “FTT=1” availability  RAID-5 • 3+1 (4 host minimum) • 1.33x instead of 2x overhead • 20GB disk normally takes 40GB, now just ~27GB RAID-5 parity data data data parity data data data data data data parity data data data parity ESXi Host ESXi Host ESXi Host ESXi Host

  22. All Flash Only RAID-6 Erasure Coding • With “FTT=2” availability  RAID-6 • 4+2 (6 host minimum) • 1.5x instead of 3x overhead • 20GB disk normally takes 60GB, now just ~30GB RAID-6 data data data parity data parity data parity data data parity data parity data data data data parity ESXi Host ESXi Host ESXi Host ESXi Host ESXi Host ESXi Host

  23. New in 6.2 Total Space Efficiency Savings Enable “All-Flash First” Choice Space Efficiency features work together to provide up to 10x reduction in dataset size 10x $1/GB 2x All-Flash for as low as $1 per usable GB * Actual deduplication and compression storage reduction will vary based on workload and configuration.

  24. New in 6.2 Virtual SAN Quality of Service • Complete visibility into IOPS consumed per VM/Virtual Disk • 1 Click-to-configure limit • Eliminate noisy neighbor issues • Granularly manage performance SLAs: independent of VM provisioning order vSphere + Virtual SAN vSphere & Virtual SAN …

  25. New in 6.2 New in 6.2 Virtual SAN Core - Support For Pure IPv6 Overview • Operate VSAN in IPv6-only mode. All network communications are through IPv6 network • Configuration through UI • VSAN supports L2 or L3 multicast • Monitor/Management through HealthUI • Support mixed IPv4 & IPv6 for upgrade process Benefits • Address the needs of the customers who are moving to IPv6 (e.g. Federal, Service Providers) • Align with vSphere support of IPv6 Support for pure IPv4 or IPv6 networks vSphere & Virtual SAN VSAN network VSAN network VSAN network Virtual SAN Datastore

  26. Virtual SAN Core - Software Checksum Overview • End-to-end checksum of the data to detect and resolve silent disk errors • Checksum is enabled by default as a cluster wide setting • Fetch the data from another copy in case of checksum verification failures • Disk scrubbing will run in the background Benefits • Provide additional level of data integrity • Automatic detection and resolution of silent disk errors Virtual SAN

  27. New in 6.2 Virtual SAN Core - Other Improvements Client Cache • Write through read memory cache • “Local” to the virtual Machine • Low overhead, big impact Sparse Swap • Reclaim Space used by memory swap • Host advanced option enables setting policy for swap to no space reservation.

  35. Module Overview CONFIDENTIAL

  36. Module 1 - Requirements VSAN Requirements • vCenter Server • Virtual SAN 6.0 requires ESXi 6.0 and vCenter Server 6.0 • VSAN is configured and monitored via the vSphere Web Client and this also needs to be version 6.0. • vSphere ESXi • Virtual SAN requires at least 3 vSphere hosts. (where each host has local storage) in order to form a supported Virtual SAN cluster. This is to allow the cluster to meet the minimum availability • The maximum number of hosts supported is 64. • Each vSphere host in the cluster that contributes to local storage to Virtual SAN must have at least one hard disk drive (HDD) and at least one solid state disk drive (SSD). CONFIDENTIAL

  37. Module 1…Requirements continued VSAN Requirements • Disk and Network • IMPORTANT : All components ( hardware, drivers, firmware ) must be listed on the vSphere Compatibility Guide for VSAN. All other configurations are unsupported. • One SAS or SATA host bus adapter (HBA), or a RAID controller that is in passthrough or RAID 0 mode. • Hybrid disk group configuration. At least one flash cache device, and one or more SAS, NL-SAS or SATA magnetic disks. • All-flash disk group configuration. One SAS or SATA solid state disk (SSD) or PCIe flash device used for caching, and one or more flash devices used for capacity. • VSAN datastore. • Each host must have minimum bandwidth dedicated to Virtual SAN. 1 GbE for hybrid capacity, 10 GbE for all-flash capacity • A Distributed Switch can be optionally configured between all hosts in the VSAN cluster CONFIDENTIAL
