Thank you, Tonya, and good afternoon, everyone. I hope that you and your loved ones are safe and healthy. I appreciate you joining us today on such short notice. I realize that we had a scheduled call next week, but with all the news we had to share, we thought it best to connect with you as soon as possible.
As I speak with you today, I'm filled with a deep sense of gratitude and fulfillment about the year and the decade at large. Earlier this afternoon, in addition to our earnings release, we issued a press release announcing a succession plan around my role, along with news of a significant investment in our business by Bain Capital Private Equity. Before we talk in detail about our results, I'd like to offer some perspective on these announcements.
2020 has been, for lack of a better word, an extraordinary year. For Nutanix, this has been a year marked by continued progress in our journey to become a pioneer in hybrid cloud infrastructure, a self-fulfilling prophecy for a market category best known as HCI. We've also shown deep resilience in a business and an expanded value that our services provide to customers in a rapidly changing and uncertain world. With a focus on innovation and collaboration, we've expanded our customer base, launched a suite in bare metal with AWS and successfully continued towards our transformation to a subscription-based business model. While our progress this year has not always come in a straight line due to the global pandemic, we're extremely humbled by the execution and effort put forth by our more than 6,000 employees around the world to deliver a strong performance in our fiscal fourth quarter.
As the end of our fiscal year approached, I also had the opportunity to step back and consider all that we have achieved. When my cofounders and I started this company 11 years ago, Apple iOS, virtualization beyond test and development workloads and web scale infrastructure using commodity hardware were novel concepts in the enterprise. Thanks to the hard work of so many, both inside and outside the company, that vision to bring an Apple-like simplicity and consumer cloud-like scale to enterprise computing has become a reality. Nutanix has grown from a scrappy start-up to a company with $1.6 billion in annual software and support billings.
With our strong fourth quarter financial results, our future-proof business model in subscription and a meaningful seeding of our hybrid cloud strategy, Nutanix is well positioned as a cloud software company in the era of invisible computing. In addition, the recent $750 million investment by Bain Capital ensures a strong financial foundation to capitalize on the significant growth opportunities ahead. I'm confident, therefore, that there's no better time for a CEO succession plan than now to really shepherd this company through its next decade of growth and success.
I'm proud of all that we've accomplished at Nutanix. It's really been a labor of love. At the same time, getting to this point has meant putting everything else in life on the back burner. In recent months through the lockdown that we've all experienced, I've had the time to reflect and had many conversations with my wife as well as my fellow Board members. And what I have come to conclude is that I need to spend more time with my family and allow myself the space and flexibility to read and write and learn new domains. It simply hasn't been possible while I have been devoted 110% to this company.
That being said, I will continue to lead Nutanix while the Board conducts the search for our next CEO. We'll take the time to find the right leader with a strategic vision, a track record of customer success and all the personal qualities we value at Nutanix. Given our robust people foundation and very loyal customer base, we expect this succession plan to be a natural process of the company's evolution and therefore seamless for both Main Street and Wall Street.
Among other things, a strong balance sheet also ensures that we can cast a wide-enough net to search for a CEO who can maximize long-term value. That is why I'm so excited to announce a meaningfully large $750 million investment from Bain Capital. This investment will provide us robustness to support and even accelerate our subscription transition, help us compete better and help us remain at the forefront of design and innovation in our industry. As part of this investment, David Humphrey and Max de Groen, Managing Directors of Bain, will join the Nutanix Board upon closing, and we look forward to this newly forged partnership.
Founding Nutanix and being subservient to our customers from day one has been my passion and the highlight of my professional career, and I want to thank all the employees, past and present, for helping me bring this idea to life this last decade. I'd like to express my deepest gratitude to my wife and my fellow cofounders for giving me the courage to imagine and help create something out of nothing. As many of you know, Nutanix is coming second only to my family, and I'm extremely proud of what we have built with this monomaniacal focus on commodity-powered innovation, from consolidating proprietary hardware with one-click HCI to consolidating data centers with one-click private cloud to now consolidating a myriad cloud with one-click hybrid cloud.
I was telling Max and Dave from Bain Capital these last several weeks of our financing discussions. We have a tremendous "payload" to deliver in the next 1 to 3 years, owing to both the subscription transition with its efficiency payoff and our product portfolio transition with its platform payoff. That payload over the next 1 to 3 years and Bain's extensive market due diligence is what drove their conviction for such a large investment. The new capital will give Nutanix the staying power to build on our success of hyperconverged infrastructure and extended to build a new HCI category, hybrid cloud infrastructure.
As we reflect back on the year, our narrative has 3 distinct and recurring pillars: Growth, scale and cash. First, the global pandemic reaffirmed our premise that a lift and shift to cloud, both private and public, is more strategic than ever to businesses around the world. And this, in turn, will continue to drive growth for as long as we keep adding new customers to our flywheel. Second, our subscription transition at scale with our loyal customer base, as proven by our industry-leading customer retention, is helping us grow meaningfully, as evidenced in our run rate or book of business ACV. And finally, our execution on OpEx during COVID, both in marketing, sales and in overall expenses, has helped us with both operating margins and free cash flow. Between this OpEx discipline and the Bain investment, we feel very comfortable about cash for the future.
Speaking of the quarter, Q4 ACV billings grew 13% year-over-year to $140 million. Non-GAAP gross margin reached an all-time high at 83%, up 3 points from a year ago. For fiscal 2020 on a year-over-year basis, ACV billings grew 18% to $505 million, run rate ACV or book of business grew 29% to $1.22 billion and deferred revenue grew 30% to $1.2 billion. This is a humbling and gratifying end to the fiscal year in a very difficult macro environment.
In Q4, we also closed a record high of 68 deals worth over $1 million of TCV, up 19% year-over-year. 13 of these customers also spent at least $1 million with us last quarter. We now have a total number of 17,360 customers worldwide, 920 of which are Global 2000 customers. For Global 2000 customers who have been with us for at least 18 months, their repeat purchase multiple has expanded to nearly 14x. We also have 1,207 customers with a lifetime spend of at least $1 million, up from 921 a year ago.
A highlight of the quarter, our largest deal with a subscription contract worth nearly $8 million with a global financial services organization headquartered in Australia. This organization selected Nutanix over the competition in their data center modernization journey off of legacy 3-tier hardware several years ago. They're now running all of their critical and client-facing apps on Nutanix HCI. They love us because of our reliability and ease of use and because our software helps them ensure regulatory compliance around disaster recovery.
Another great example is a company selecting Nutanix for its strategic IT initiative is an existing public sector customer in EMEA. This local government district authority in the U.K., a long-time customer, purchased nearly $2 million of our software and services in Q4 to run all of their core applications and use our disaster recovery as a service, Xi Leap, to power their hybrid cloud infrastructure.
Speaking of software and services, let me underscore our product portfolio and the role it continues to play in the infrastructure market. This month, Forrester once again recognized us as being a leader in the hyperconverged infrastructure wave, notably ahead of other players in the segment. Our customers vouch for us in such analyst research because we work the whole body of delivery, a reliable core product that is simple to use, a phenomenal customer service and an innovation engine that they can subscribe to as they consume a well-integrated platform.
Because of this platform-driven, solutions-focused approach, we continue to see momentum behind adoption of our entire product portfolio in Q4. Specifically, DR-as-a-service, Leap; desktop-as-a-service, Frame; and database-as-a-service, Era products, all had record quarters. In fact, our attach rate for data center, DevOps and desktop services, i.e., products beyond the HCI core, increased to 33% in Q4 from 26% a year ago and now account for 15% of new ACV, up from 12% a year ago.
A great example of a customer repurchasing solutions on top of our core software this quarter is a state and local government organization in the United States that selected $1.5 million of our software in Q4 in a deal that included our core software, our invisible hypervisor AHV as well as Frame, Files, Flow and Era. This customer has a lifetime spend with us of $12.5 million and has grown the Nutanix footprint from 3 nodes in 2014 to over 400 nodes.
This quarter, we also reached significant milestones with our solutions, including our Xi Government Cloud solution achieving FedRAMP authorization, providing our customers with a uniform approach to risk-based security management. We announced new capability for Xi Frame, providing strength in security, increased flexibility and broader regional availability for our multi-cloud desktop service. We also launched new solutions that allow IT teams to deploy, upgrade and troubleshoot their cloud infrastructure while working from anywhere, whether at home or from a central office location. It's something that is even more important now. And finally, we announced a milestone for our Files solution, having reached 2,500 customers globally.
During the quarter, we also reached a significant milestone in our journey to morph HCI from hyperconverged infrastructure to hybrid cloud infrastructure. A few weeks ago, we announced the general availability of Nutanix Clusters on AWS, which extends the simplicity and ease with use of our software to the public cloud. This is a significant step in realizing our vision to make computing invisible anywhere by delivering a singular experience across multiple clouds, public or private. This portability eliminates the complexity of multi-cloud environments with unified operations and seamless app mobility across locations, addressing the key technical and operational challenges of hybrid cloud computing. Nutanix Clusters' ease of use, license portability and networking and data locality architecture are its key differentiators. It allows organizations to build a hybrid cloud in under an hour, including disaster recovery sites, [ legacy ] applications and data-intensive workloads. This architecture and design simplicity make lift and shift of the enterprise's most mission-critical workloads, for example, databases, latency-sensitive applications and DR sites, imminently one-click. Nutanix Clusters provide customers with the flexibility to deploy any application in any cloud with the added benefit of license portability across public and private locations, which meaningfully protects our customers' investment in software infrastructure.
Our subscription journey at scale is another important area that I'd like to highlight. In Q4, 88% of our billings were from term-based subscription contracts. Starting Q1 this new fiscal, we began to align our sales forces' incentives to ACV goals, similar to what we had done with TCV goals when we moved from hardware appliances to software. I'm very excited about the possibilities this new phase of our transition brings to our business model and our go-to-market efficiency. More on this from Duston later.
Another factor that drove our results for the quarter and throughout the year was continued focus on all things digital to help our OpEx. Like many technology companies, our global employee base is still largely sheltered in place due to the pandemic. As I mentioned last quarter, we have moved the marketing and sales efforts to be predominantly digital. We doubled down on Test Drive, a seminal digital initiative within the company to enable our prospects to experience our entire solution portfolio with a zero-touch, self-service, Google Cloud-powered platform.
The same low- to no-touch digital experience is showing in our ability to prospect and sell with virtual meetings throughout the world. The ability to pull off an entirely virtual mega marketing event will be put to test between September 8 through the 11 when we'll have the biggest customer event of the year, our .NEXT event. I encourage all of you to join us remotely. A link to register for free can be found in our earnings press release. .NEXT have been completely reinvented to provide an online interactive experience that includes the visionary keynotes our customers and partners have come to expect as well as hands-on technology sessions and the ability for attendees to interact and learn with us.
Before I turn over to Duston, I'd like to say that it's been an honor to lead this insurgent company over the past decade. Our people have built a unique company that is obsessed with our customers and demonstrated that operating system software can be built from scratch even in the presence of large, well-funded incumbents. It's come to be known as one of the most customer-centric, design-oriented, empathy-driven cloud software companies in the world. I know that my legacy will continue as I pass the baton in the coming quarters. There's a mark of pride I feel in having led the team from $0 to $1.5-plus billion in annual billings in 10-plus years, and I'm very confident that we'll continue to build on this success this coming decade. With an envious customer loyalty scorecard, a delightful platform that will make hybrid clouds elegant and a strong balance sheet to fund our transition and navigate this upcoming economic recovery, Nutanix is a company to watch for this decade.
Now I'd like to turn this over to Duston for him to elaborate on how we plan to cautiously navigate this ACV transition during a highly uncertain macro environment, albeit as a fully capitalized company for the future. Duston?
