SECURITIES AND EXCHANGE COMMISSION

Washington, D.C. 20549

SCHEDULE 14A

(Rule 14A-101)

Proxy Statement Pursuant to Section 14(a) of
the Securities Exchange Act of 1934 (Amendment No.     )

EXPLANATORY NOTE

Set forth below is a Form 8-K and press release first published, sent or given by Datalink Corporation on November 29, 2016.

Subject Line: An Insight & Datalink Update

Email  Body:

We’d like to take just a few minutes of your time to provide an update as it relates to Insight and Datalink coming together.

Things are moving along smoothly, with the preliminary proxy filing taking place Friday, Nov. 18, as expected. In addition, we expect to file the definitive proxy statement this week.

As many of you know, the week of Nov. 7, we also had the opportunity to visit a number of Datalink offices and to share the collective rationale behind this announcement. We came away from the meetings even more excited and convinced this combination is going to be great for both companies. We’d like to reinforce the three key reasons for doing this:

1.               Strategy: Both companies recognize the opportunity for growth in the data center and cloud: private, public and hybrid. Datalink has done an outstanding job with data center, and its technical and architectural skills are second to none.

2.               Culture: We feel strongly that our cultures are well-aligned, and our week traveling made this even more evident. Our purpose to build meaningful connections to help businesses run smarter resonated well with Datalink, and we believe our three core values of Hunger, Heart and Harmony are also well-aligned.

3.               Economics: Coming together makes both companies stronger for the future in the fast-changing data center space.

Also of note, the advantages for both companies:

Insight provides Datalink …

·                   A strong public cloud position with Azure, Amazon Web Services and others with associated technical skills

Datalink provides Insight …

·                   Best-in-class data center skills and technical talent

·                   Complementary geographic strength in many markets

·                   Excellent services capabilities like OneCall

·                   Leading storage expertise

As previously noted, there is a process and protocol to follow, and as such, we must continue to operate as competitors until closing. A core cross-functional team from both companies is working diligently on the plans to ensure an effective and smooth transition after the closing.

It’s our intention to communicate progress to all teammates as definitively as possible in the coming weeks, and we look forward to providing you more details when we can.

Thank you for your time. We hope you and your families had an enjoyable Thanksgiving and wish you a happy holiday season.

Best,

Rule 14a-12 Legends
