In a traditional virtual desktop infrastructure (VDI) deployment, one of the biggest costs is storage. In the past, the storage infrastructure required to meet the needs of a demanding, real-world VDI could quickly outprice any VDI solution, especially when compared to the falling cost of desktops and laptops. This brings the need for a solution that provides speed, reliability and scalability for VDI at a price-point that doesn’t doom the project to failure before it even begins.

Nutanix has a better approach to scalable VDI infrastructure

Utilizing a brand-new file system, Nutanix is a 100% software-defined solution that turbocharges your virtualized data center. With the Nutanix Distributed File System (NDFS), local storage is transformed into a scalable, virtualized storage cluster that supports all the advanced hypervisor features your data center relies on, including vMotion, DRS, HA and FT. Each 2U Nutanix appliance (block) can contain up to four nodes with their own compute and storage resources, giving you true freedom to scale out at a pace that fits your project. With auto-tiered, server-attached PCIe flash, SSD and large-capacity SATA drives, Nutanix takes the guesswork out of designing a VDI solution for your business.

VDI performance on Nutanix

Starting at 2,000 MB/s of sequential throughput and 30,000 random IOPS in a four-node cluster, the potential for VDI with Nutanix is limitless. One of the biggest problems with VDI in the past, especially on traditional SAN storage, was the scalability. Every disk tray added represents a significant investment and eventually runs into IO limits. Once that capacity is maxed out, you must purchase a completely new storage rack at a significant increase in both purchase and run costs (power, cooling and data center floor space).

Most VDI projects that begin on traditional SAN storage eventually end when performance can no longer be consistently maintained. As anyone who has ever had to go back to the CFO and request additional post-deployment dollars can attest, it’s not something you want to do just to maintain reliable VDI performance. The only way around this problem in the past was to buy a lot more storage than you initially needed to assure that, when fully in production, you could meet future requirements – usually at astronomical costs on day one.

VDI requires the same level of high performance day in and day out. End-users are counting on an experience that replaces their traditional desktop, and degraded performance at scale is not an acceptable option for any user.


In a Nutanix deployment, you scale out at your own pace. Because performance is the same at 400, 800, 1,200 or even 12,000 users, its predictable, linear scale-out performance is a great advantage in getting Nutanix approved by whomever oversees the budget. You can reliably plot a course from start to finish and know with complete confidence that, on a predictable increase of users, you can move up without needing to go back to the storage vendor. Simply slide in a new node, and continue along the deployment schedule.


Ease of deployment

Taking the best methodologies from cloud providers, Nutanix is designed to be ready for your virtual desktops within an hour of racking the hardware, significantly increasing time-to-value and speed-to-market. Now with just three clicks, your new storage and compute resources are ready for virtual desktops. Software-defined replication enables granular per-VM data protection policies that can easily be grouped for effective DR planning and runbook automation, even across multiple data centers.

A Nutanix solution is ready to help your VDI project succeed by:

  • Eliminating harmful boot storms
  • Providing predictable scale-out performance
  • Reducing CAPEX by 40% to 60%
  • Enabling efficient clones with VAAI and VCAI
  • Providing up to 10x reduction in rackspace
  • Offering a 5x reduction in project completion times
  • Deploying easily in remote offices.
  • Offering VDI performance assurance: Nutanix is the only vendor that guarantees in writing your VDI will perform
