Here are some of the latest executive hirings, promotions and staff changes that happened in September. If you’d like SDxCentral to report on your company’s movers and shakers, or if you’ve got a tip about layoffs and restructuring, please send the information to Emma Chervek ([email protected]) for inclusion in our monthly headcount column.

Ilan Eframian recently joined Comcast as VP of its Xfinity Communities division, a move that he told SDxCentral provided something he did not have with similar roles at Google Fiber and Verizon: “a single word: scale.”

“Comcast is just so big,” Eframian told SDxCentral. “I didn’t really appreciate how big it was until I joined. Verizon is not a tiny company. Google’s obviously a big company but Google Fiber is very small. Xfinity is the largest provider of gigabit broadband in the U.S. … When that opportunity came up for me it was pretty easy.”

Xfinity Communities is Comcast’s division that focuses on providing broadband and cable television connectivity to multifamily properties, campus locations, apartments and mixed-use developments. Xfinity Communities currently serves approximately 200,000 properties and 15 million units.

The Linux Foundation‘s Open19 project has rebranded as the Sustainable and Scalable Infrastructure Alliance (SSIA) in a move to address the growing presence of sustainability challenges in the data center and IT infrastructure industries. The newly-dubbed SSIA also shared Chairperson Zac Smith’s plans to step down from the post he has held since 2016, with Equinix Field CTO My Truong taking his place.

According to Truong, the current technology landscape boasts significant opportunities to innovate while “reducing the environmental impact of IT as a good business practice,” he said. “I’m committed as the SSIA chairperson to being a part of getting this important mission right.”

Smith plans to remain “heavily involved” in SSIA as a board member and was part of the process to change the face of Open19 — an open-source project focused on developing a community-driven framework that approaches complex issues like sustainability and open standards within “one part of the digital infrastructure landscape,” Smith told SDxCentral.
