This presentation discusses storage solutions for VMware Horizon View environments. It begins with several tips for evaluating storage needs such as performing an assessment of the current environment. Various storage technologies are then compared, including virtual SAN, all-flash arrays, and hybrid arrays. VMware Virtual SAN is discussed in more detail as a simple, hyper-converged solution that provides high performance. The presentation concludes with considerations for using all-flash arrays with Horizon View to provide consistent high performance for virtual desktop infrastructures.

- 26. 26 View Storage Accelerator SE Sparse Virtual Volumes Storage IO Controls What is it? In-memory cache of common block reads Reclaim unused space and keep linked clones small. Deploy desktop pools based on storage characteristics Provide I/O prioritization for virtual machines running on a group of VMware vSphere hosts that have access to a shared storage pool Pro’s Decrease Peak IOPS load by up to 80% Lower storage capacity requirements even on lower-end platforms Great way to segment and tier based on use- case. Completely automated; works with any storage Con’s May slow down recompose operations dramatically Reclaim operations MUST be scheduled during off hours. No View Integration; hardware specific No View Integration; usually too late to protect user experience Ideal for Protect from read storms on a budget Limited storage capacity; flexible maintenance windows. Large environments with well-defined use cases Smaller environments with demanding workloads
- 27. 27 7. The Importance of Tuning
- 28. OS Optimization Tool (OSOT) • What – A standalone tool to optimize Windows OS image for Horizon View. • Benefit – Improve performance and optimize infrastructure. Reduce CPU/memory/storage/network overhead. • How – By disabling unnecessary services/features, customize configurations, etc. • Fling – https://labs.vmware.com/flings/vmware-os- optimization-tool • Derived from VMware OS Optimization Guide f or Horizon View. 28

- 30. Calculators and Formulas • Calculators will use rule of thumb numbers – unless you have real numbers • Very high tech napkin • Great for planning, bad to solely on for implementation • Our PSO and Partners never rely strictly on calculator 30
- 31. Space and Performance • Always do space calculations – Trust but verify • Things that impact space calculations: – Using Local SSD or PCI Flash • Stateless Desktop for example – Full Clones – Linked Clones • Persistent disks • Disposable Disks • Recompose frequency & SESparse – View Storage Accelerator (CBRC) – Memory Reservations (vswap) • Do IOPS calculations – Except when it doesn’t matter • Things that impact performance: – View Storage Accelerator (CBRC) • Don’t overcommit server RAM!! – Array type – Array cache – Storage tiering – Storage Network – VAAI 31 Space Performance
- 32. 32 9. Rules of Thumb
- 33. Rules of Thumb 33 • You will find other rules of thumb guide numbers – that’s why they can be dangerous…confusing…wrong • Keep in mind these are average numbers – Read / Write Mix – Bursts – Boots, Provisioning. Logins, Lunar Cycles, Antivirus – Average Numbers = Likely failure
