Some say that no one dreads a day of downtime like a storage admin.
I disagree. Sure, the storage admins might be responsible for recovering a whole organization if an outage occurs; and sure, they might be the ones who lose their jobs from an unexpected debacle, but I would speculate that others have more to lose.
First, the company’s reputation takes a big, possibly irreparable hit with both clients and employees. Damage control usually lasts far longer than the original outage. Take the United Airlines case from earlier in 2017 when a computer malfunction led to the grounding of all domestic flights. Airports across the country were forced to tweet out messages about the technical issues after receiving an overwhelming number of complaints. Outages such as this one can take months or years to repair the trust with your customers. Depending upon the criticality of the services, a company could go bankrupt. Despite all this, even the company isn’t the biggest loser; it is the end-user: and that is what the rest of this post will focus on.
Let’s say you’re a senior in college. It’s spring term, and graduation is just one week away. Your school has an online system to submit assignments which are due at midnight, the day before finals week. Like most students at the school, you log into the online assignment submission module, just like you have always done. Except this time, you get a spinning wheel. Nothing will load. It must be your internet connection. You call a friend to have them submit your papers, but she can’t login either. The culprit: the system is down.
Now, it’s 10:00 PM and you need to submit your math assignment before midnight. At 11:00 PM you start to panic. You can’t log-in and neither can your classmates. Everyone is scrambling. You send a hastily written email to your professor explaining the issue. She is unforgiving because you shouldn’t have procrastinated in the first place. At 1:00 AM, you refresh the system and everything is working (slowly), but the deadlines have passed. The system won’t let you submit anything. Your heart sinks as you realize that without that project, you will fail your math class and not be able to graduate.
This system outage caused heartache, stress and uncertainty for the students and teachers along with a whole lot of pain for the administrators. The kicker is that the downtime happened when traffic was anticipated to be the highest! Of course, the servers are going to be overloaded during the last week of Spring term. Yet, notoriously, the University will send an email stating that it experienced higher than expected loads; and that ultimately, they weren’t prepared for it.
During this time, traffic was 15 times its normal usage, and the Hypervisor hosting the NFS server and the file sharing system was flooded with requests. It blew a fan and eventually overheated. Sure, the data was still safe inside the SAN on the backend. However, none of that mattered when the students couldn’t access the data until the admin rebuilt the Hypervisor. By the time the server was back up and running, the damage was done.
High Availability isn’t a simple concept but it is critical for your organization, your credibility, and even more importantly, for your end-users or customers. In today’s world, the bar for “uptime” is monstrously high therefore downtime is simply unacceptable.
If you’re a student, an admin or a simple system user- I have a question for you (and don’t just think about yourself, think about your boss, colleagues, and clients):
What would your day look like if your services went unresponsive right… NOW?!
