How to Replace Your Default ESXi SSL Certificate With a Self-Signed Certificate: a 101 Introduction

Everybody knows that SSL certificates are a must-have for every safe network. However, anybody who has ever worked with ESXi hosts has sometimes had to deal with untrusted certificates, which can become quite tedious. Fortunately, there is a sure fix.

How to Replace Your Default ESXi SSL certificate With the Help of a Local Domain Certificate Authority (CA): a 101 Introduction

In the previous article, I have shared a working algorithm on replacing the ESXi SSL certificate with a self-signed one, but, as you know well, there’s always room for perfection. So, I have been practicing with a more universal scenario that could also work with a domain infrastructure and domain certificate services. That’s what I came up with.

Virtualization: Performance Comparison

As you remember from my previous article, I have been interested in testing the performance levels of two virtual SAN configurations from different vendors. I got my results, but this experience prompted me to continue. Here, I’ve chosen to try another configuration for performance comparison, albeit with only a slightly different list of participants.

Since no one needs an introduction from VMware vSAN, I’d like to say a few words about its companion – Ceph. Basically, it is an object-based software storage platform. I know that doesn’t sound epic at all, but Ceph is also completely fault-tolerant, uses off-the-shelf hardware, and is extremely scalable. The most interesting thing is that some Ceph releases apply erasure-coded data pools so that it would be a less resource-hungry solution than traditional replicated pools. In practice, that means the following: when you store an object in a Ceph storage cluster, the algorithm divides this object into data and coding chunks, stored in different OSDs (that way, the system could lose an OSD without actually losing the data).

Now, that’s when I thought that theoretically, Ceph could make a good virtualization platform (proper configuration, of course), so I had to see whether it would be justified in terms of time and resources spent. Naturally, I hardly could have done it without a credible comparison, hence VMware vSAN (with a similar configuration, of course, otherwise it would make no sense).

So, shall we?

Virtual SANs: Are They Really All Alike?

As time goes on, fewer and fewer people tend to rely on cumbersome SANs. It doesn’t mean that they have become obsolete; it’s just that many small and medium-sized enterprises (SMEs) simply don’t require all the broad specter of services and resources that a storage area network system can offer. That makes perfect sense: if you can farewell with a less complicated and resource-hungry configuration – why pay more?

Virtual SANs have become the newfound Holy Grail of small infrastructures. And why not? They offer software-defined storage solutions that support HCI systems and leave external shared storage out of the picture. An introduction of virtual SAN solutions to the market has changed a lot, opening the way for simple storage configurations that can provide maximum possible performance with minimum possible resources required, respectively.

Since the market has emerged, it didn’t take long to recognize the leaders, which are StarWind Virtual SAN (VSAN) and VMware virtual SAN (vSAN). All else being equal, neither is considered better or worse. However, each IT environment is, in a way, unique. I don’t need to tell you about the multitude of configurations out there. So, with the diversity of HCI systems and hardware requirements in mind, this begets a question: are these solutions really giving away an equal performance, all things considered?
