Re: Registration Statement on Form S-8

Ladies and Gentlemen:

We have examined the Registration Statement on Form S‑8 (the “Registration Statement”) to be filed by Nutanix, Inc., a Delaware corporation (the “Company”), with the Securities and Exchange Commission on or about the date hereof, in connection with the registration under the Securities Act of 1933, as amended, of 9,200,000 shares of Class A Common Stock reserved for issuance pursuant to the Company’s Amended and Restated 2016 Employee Stock Purchase Plan (which plan is referred to herein as the “Plan” and which shares of Class A Common stock are referred to herein as the “Shares”). As your legal counsel, we have reviewed the actions taken and are familiar with the actions proposed to be taken by you in connection with the issuance and sale of the Shares under the Plan and pursuant to the agreements related thereto.

It is our opinion that the Shares, when issued and sold in the manner referred to in the Plan and pursuant to the agreements which accompany the Plan, will be legally and validly issued, fully paid and nonassessable.

We consent to the use of this opinion as an exhibit to the Registration Statement, and further consent to the use of our name wherever appearing in the Registration Statement and any amendments thereto.

Sincerely,

WILSON SONSINI GOODRICH & ROSATI
