She joins the company from Anixter where she worked as an inside sales representative.
Du Plessis previously held account management roles at Ultimate IT Services, AtlasCo, Polaris Communications, and sales and related roles at IP Trading and AAPT.
"With the maturing of our new partner program, I'm taking full ownership in helping smaller partners compete in the depths of the channel and become more self-sufficient by taking away the complexity at the user level. We are also injecting incentives for the innovative work they do," said Du Plessis.
"Alongside locally reliable, on-the-ground support, it's the vertical expertise of our partners that will be fundamental to the customisation and flexibility of edge solutions, and we want to be the backbone of that partnership."
Locksley McKay joins Vertiv as an IT channel sales executive.
He previously worked in sales at Sapio after a short stint at Logicalis.
"As a channel organisation, our partners are the lifeblood of our business," said McKay.
"By expanding our support for local partners, we're helping companies build resilience into their architecture and handle both long-term growth and business-as-usual workloads."
Du Plessis and McKay will work closely with Vertiv's local partners, including xAmplify, Data 3 , Dell Enterprise, HPE, and NTT Global.
The company's channel team is participating in the 11 August 2021 healthcare and education-focused roundtable that's being hosted by Vertiv in conjunction with Tech Data, xAmplify and Nvidia. Invitations will be sent in the next weeks.
