Industry-proven Solutions for VDI with Tintri and Citrix
The decision to virtualize desktops can get stuck when the storage underneath can’t keep pace with the demands. Managing a virtual desktop infrastructure (VDI) can be complex and costly due to the large number of components involved. You need industry-proven solutions such as Tintri VMstore and Citrix XenDesktop to help you guarantee performance and flip storage from anchor to enabler.
Challenges of VDI Deployments
The promise of VDI is clear. Virtualizing and centralizing desktops offers a more secure and man- ageable end-user computing model. However, managing an increasing number of users while maintaining user experience remains very challenging for IT organizations.
Organizations that have decided to enable VDI often accept that it’s supposed to be complex, and that storage in particular will be a source of pain. Tintri challenges those assumptions.
Common barriers to realizing the full potential of VDI include:
Poor Performance: Performance can be impacted by: boot storms, virus scans, latency spikes and even unpredictable user workloads. The performance shortfalls can inhibit user acceptance and diminish productivity.
Lack of Visibility: LUNs, volumes, RAID groups, and other components of conventional storage systems render it virtually impossible to have visibility. Problem outliers and one-off perfor mance issues that degrade system reliability and usability can remain hidden behind a veil of complexity.
Management Complexity: Most VDI administrators are not storage experts. Yet conventional storage systems require expert-level knowledge just to troubleshoot. That complexity can hinder the rapid resolution that is sometimes essential to properly managing VDI.
Combining the Power of Citrix and Tintri
With industry-proven Tintri VMstore and Citrix XenDesktop solutions:
Your VDI team shouldn’t require a storage PhD to deliver great performance. Keep Citrix XenDesktop deployments and management both simple and scalable – as many as 5,000 desk tops in a single logical datastore on one Tintri VMstore.
Each desktop VM, whether it’s a task worker or power user, has its own “lane”. Tintri quality of service (QoS) guarantees performance. Desktop and server workloads can coexist on the same VMstore without creating contention.
No more overprovisioning – Tintri provides higher VM density than other storage providers—up to 5,000 desktop VMs in two rack units—and simply scales as you grow.
Tintri Unique Features for VDI
Predictable performance with sub-millisecond latencies can be achieved in a fraction of the footprint of conventional storage. The Tintri VMstore keeps users productive, effectively handling boot and login storms, desktop updates, and performance-hungry applications.
Tintri VM-aware storage (VAS) lets you focus on VMs and applications, not LUNS and volumes, consistently providing the best performance without requiring manual tuning or storage man agement. This is possible through Tintri VM-level QoS and the ability to eliminate “noisy neigh bor” effect between end-user and server VMs.
A single pane of glass interface provides end-to-end, VM-level visibility into performance latency across compute, networking, and storage, enabling IT to proactively solve end-user experience issues quickly and efficiently.
Direct provisioning of user desktops includes support for Citrix Provisioning Services (PVS), Citrix Machine Creation Services (MCS), and Tintri Native Clones. Tintri’s vStorage API for Array Integration (VAAI) seamlessly enhances all supported provisioning methods.
Citrix Ready VDI Capacity Program Phase II
Under this program, Tintri VMstoreTM storage system supported a realistic Citrix XenDesktop workload leveraging Citrix Provisioning Services in a simulated 1,500-user environment.
Login Virtual Session Index (Login VSI) is the industry-standard tool used for this performance and capacity testing. A total of 1,500 virtual desktop sessions were successfully launched and stress tested, running in benchmark mode as required by the Citrix Ready® program. The latency limit of VSI max was not reached at any point of the test. The VSI max average response time threshold was 1,717 milliseconds. The VSI max baseline average response time was 716 milliseconds. VSI response time threshold headroom was 1,857 milliseconds.
As conclusively shown by the results of the Citrix VDI Capacity Program benchmark test, Tintri VMstore serves as a perfect symbiotic partner for Citrix XenDesktop, handily meeting or exceeding all the requirements of the Citrix Ready® Program.
Choosing the Right VDI Software
The key to success of any VDI initiative is choosing the right desktop virtualization broker. Citrix XenDesktop delivers virtual apps and desktops as mobile services for multiple use cases. It enables increased employee productivity with anywhere access, simplifies support of BYOD (bring-your- own-device) and conventional VDI endpoints, provides desktop security to protect sensitive infor- mation, and reduces cost and complexity. Citrix XenDesktop helps solve top IT and business challenges
If VDI is on your list of priorities or you are looking to expand your current environment, Tintri can help you successfully and cost effectively deploy desktop virtualization. Tintri has developed exten- sive guides to deploying Tintri VMstore with Citrix XenDesktop, and deep dives on Tintri with XenDesktop PVS, XenDesktop MCS, and XenDesktop with Tintri Native Clones.
