HCI Failure Modes and Maintenance

I got the idea for this blog after speaking with multiple customers that were contemplating switching to certain kinds of grid computing/storage (like HCI) without fully understanding the ramifications of doing so.

You see, they were (rightly so) enamored by concepts such as automation, ease of consumption and scaling. But they forgot to ask some very important questions. See here for the dangers of getting too carried away with something new and taking things for granted.

This isn’t a post claiming HCI and grid-type storage constructs are bad. Like any tool, they can be used in various ways, some of them aggressively ill-advised. The point of this post is to help customers ask for the right configuration so they don’t get stuck with a sub-optimal and risky design.

I tried to make this post as short as possible but as someone once said, “Everything should be made as simple as possible, but not simpler”. Which, ironically, is a simplification of what Einstein actually said 🙂

The Importance of SSD (and other) Firmware Updates

I wanted to bring this crucial issue to light since I’m noticing several storage vendors being either cavalier about this or simply unaware.

I will explain why solutions that don’t offer some sort of automated, live SSD firmware update mechanism are potentially extremely risky propositions. Yes, this is another “vendor hat off, common sense hat on” type of post.
