VMware announced on Tuesday that its president and co-COO Carl Eschenbach would resign soon. It was the second news of senior officer resignation in the past week.

Eschenbach will join Sequoia Capital as a partner after his resignation. So far, VMware has not announced its successor yet.

In fact, VMware senior vice president Martin Casado just quit his post a few days ago. Casado joined Andreessen Horowitz as an ordinary partner. However, a month ahead of the brain drain, VMware announced that its CFO & co-COO Jonathan Chadwick would resign from his posts.

In addition to this, VMware also announced the appointment of four senior managers for more responsibilities. Maurizo Carli is appointed as the executive vice president for global sales business. Peter McKay will be the chief supervisor of US sales team. Its current CTO Ray O’ Farrell will be also responsible for the related business concerning global business and consumer plan. Sanjay Poonen will be responsible for business of global sales and public relations.

The management group adjustment is worth noting as Dell just acquired EMC, the parent company of VMware. EMC holds 80% of VMware’s stock equity. The $67 billion acquisition was approved by the US regulatory last week.

VMware streamlined about 800 employees last month. What’s more, VMware announced to decrease the expectation of 2016 revenue in the latest quarterly report.
