2 Different Public Address for High Availability
pf flag

this is my first time asking a question here, and I was wondering is it possible to have two different ISP public IPs connected to a single system for high availability?

for example, if our ISP 1 became offline the 2nd ISP will be available, just like google and youtube have different Public addresses, I am just at a loss where to config this.

we are currently using fortinet 300D.

Troubleshooting SATA/SAS reverse breakout cable

For a new server build, I'm trying to connect a SAS HDD backplane (SFF-8643) to a SATA motherboard. From my research, this should be possible using reverse breakout cables.

I bought and installed two "SFF-8643 to 4x SATA" reverse breakout cables, but when I start the machine it does not recognize any of the disks (all SATA) on the backplane. As a spot test, I connected one of the disks directly t ...

The Stunning Power of Questions

Much of an executive’s workday is spent asking others for information—requesting status updates from a team leader, for example, or questioning a counterpart in a tense negotiation. Yet unlike professionals such as litigators, journalists, and doctors, who are taught how to ask questions as an essential part of their training, few executives think of questioning as a skill that can be honed—or consider how their own answers to questions could make conversations more productive.

That’s a missed opportunity. Questioning is a uniquely powerful tool for unlocking value in organizations: It spurs learning and the exchange of ideas, it fuels innovation and performance improvement, it builds rapport and trust among team members. And it can mitigate business risk by uncovering unforeseen pitfalls and hazards.

For some people, questioning comes easily. Their natural inquisitiveness, emotional intelligence, and ability to read people put the ideal question on the tip of their tongue. But most of us don’t ask enough questions, nor do we pose our inquiries in an optimal way.

The good news is that by asking questions, we naturally improve our emotional intelligence, which in turn makes us better questioners—a virtuous cycle. In this article, we draw on insights from behavioral science research to explore how the way we frame questions and choose to answer our counterparts can influence the outcome of conversations. We offer guidance for choosing the best type, tone, sequence, and framing of questions and for deciding what and how much information to share to reap the most benefit from our interactions, not just for ourselves but for our organizations.
