I've worked closely with Dell since 2007. Back then, we could create a "Severity 1" case. I think they've discontinued that option. Now, you can create a "Severity 2" case. For Severity 1 issues, you can call the helpline. I've often recommended to Dell EMC Pakistan that there should be a portal option to create Severity 1 cases. Their engineers are good, but since COVID, many experienced engineers have left the company. This is a problem for every vendor, not just Dell EMC – they face challenges finding experienced technical engineers. So, while I recommend Dell EMC, sometimes they don't have the technical staff for very quick responses. In those cases, you might need to engage your account manager to find the best engineer on a Severity 1 issue.
