Looking to upgrade Kemp LoadMaster in a High Availability (HA) mode? Our guide is focused on simplicity and practicality.

Running a company heavily reliant on IT services and wondering how to improve business continuity? Our new article explains the key differences between High Availability (HA) and Fault Tolerance (FT) and will help you choose the right IT resilience strategy.

A Kemp LoadMaster appliance is a critical service for load balancing and application content delivery. Thanks to flexible deployment options for a wide range of hypervisors and cloud platforms, Kemp LoadMaster allows you to distribute user traffic and improve application performance in private and hybrid cloud systems intelligently and efficiently. At the same time, usually Kemp is in front of critical services such as E-mail, web applications, SharePoint and if you lose it, you’ll get service outage. Deploying an HA cluster will solve this problem and provide a high availability, especially for a physical appliance!

VMware vSphere 6.5 is the latest version of the enterprise server virtual platform from VMware, but the new beta it’s already there for testers. Actually the next version it’s (in the beta). If you are building a new infrastructure from scratch the latest stable version is probably the best choices (for most cases); but what about if you have an old environment and you plan to upgrade it?

In this article, we will discuss the split brain issue, and different approaches to prevent it from happening. The situation when communication loss between the cluster nodes is caused by network connection problems is called network partition, which can lead to split brain. According to Wikipedia, split brain is a computer term, based on an analogy with the medical split-brain syndrome. It can be a real horror for a system administrator to handle the consequences of a split brain.

There’s, probably, no IT administrator who hasn’t heard of SMB3 (Server Message Block). is an application-layer network protocol, developed by Microsoft mostly to provide shared access to the files, and allowing communication between nodes. SMB has been designed as a tool for the creation of a DOS-based network file system, but Microsoft took the initiative and renamed SMB into CIFS later on (Common Internet File System) and continued further developing it. The second version – SMB 2.0, has been introduced in Windows Vista with a wide range of new features, thus it became clear that Microsoft was working hard to improve this protocol.

Sooner or later every single IT guy comes to the idea of having some lab. There are a million reasons why you would need a lab: learning new technologies, improving skills, trying crazy ideas you would never dare to try in the production network, you name it. Even though it is a work-related activity for most home labbers this is just another hobby for many of us.  That’s why people spend so many hours of their personal time building the homelab, investing significant funds into new hardware, thoroughly planning its setup, looking for a help in online communities or sharing their experience to help others. There is a whole universe of home labbers and I am happy to be part of this community. In this post, I would like to share my experience with 3 generations of home labs I have had so far and the thoughts about next generation.

A lot of the time I see and speak to people asking about DR solutions when what they really want is HA with a few backups so I wanted to use a blog article to go through some of the technical terms used in conjunction with DR. When people say “I want DR”, I’ll ask them about the sort of disasters they are looking to protect against and most of the time the response is “I want to keep working if my hypervisor crashes”.
