How secure is secure enough?

I suppose, you have all seen my first YouTube published presentation, that I was holding in Athens. So you also know, that I was talking about security in IT. This presentation is also the one, that I had to repeat the most often till now. Most repetition have obviously been done for my employer and for our contracting partners. I do not want to repeat here, what I was talking about (because you can see this for yourself), but I want to tell you about 2 extremes that happened to me, when I approached some of our partners with security topic.

After half a year of (blog) silence

I can hardly believe, that it has passed half a year since my last published blog article. To me this time certainly did not seem that long. I would say, it has been at most 2 months 🙂 . But Chronos is merciless and is always right!

However, this does not mean I was lazy all the time! It is true, that we were also having 3 weeks of summer holidays, but also there we were very active. I will not write here about my holidays or about projects I was having at work. But let me describe some of my other (mostly private) projects of last half a year Continue reading “After half a year of (blog) silence”

E2EVC is what I was looking for!

Only few days ago, I published a blog post with tittle “Learn –> Help –> Share –> Repeat”, where I briefly mentioned  E2EVC (Experts 2 Experts Virtualization Conference) as one of the

I was at E2EVC

conferences, that are worth visiting. This was still before I have been to conference itself and I was just relying on experience of a friend and was actually just on a way to the conference itself. Now I am back and I am still trying to grasp it all, since I was literally “Blown away”. E2EVC is much more as I expected or could even hoped for. Most of other conferences, I have been till now, are only a pale imitation. Continue reading “E2EVC is what I was looking for!”

Learn –> Help –> Share –> Repeat

It is not so long time ago, when I was asked how do I manage to stay up to date with so many technologies and how am I able to follow so many streams of news that are available each day.

So many things to learn

The answer is simple. I DO NOT MANAGE IT, but I do the best I can. I do not think, that there is simple solution or single way to walk. I also doubt, that the path I am walking will work for you, but I hope you might find a thing or 2 useful and maybe you can try it out. Please let me know if it worked for you as well.

Some of S2D physical disk drives in Transient error

I was not actively involved in managing our production Storage Spaces Direct (S2D) infrastructure for few weeks now, but this weekend I was asked to help with an issue and through this I again learned a lot new. Some of my findings I want to share here with you.

Story leading to error…

This weekend was reserved for patching production S2D servers (Windows server 2016 RTM – core) with several patches out of 2018-04 bundle (KB4093119, KB4093120 and KB4093137; ##update# Error is not bound to this April CU only and has been seen earlier.##). Prior doing this, we also updated Firmware versions on our Cisco UCS servers. YES, this are the same servers I had trouble connecting to few days ago and I blogged about solution here.

It all started easy and first (out of 6) server was updated without a glitch. There was also no troubles for StorageJobs to complete and all S2D volumes were up and healthy. OK. Time to go to second server… Here all updates also had no trouble to install.

Trouble with Physical drives…

After completed patching, we were faced with surprise. Continue reading “Some of S2D physical disk drives in Transient error”
