Crashed Microsoft Exchange 2013 Database? No sweat. Learn how to recover it with ease

Companies often store critical client mailbox data on an Exchange server database. The Exchange database is a warehouse of critical mailbox information such as contacts, notes, calendar items and emails of thousands of users. One of the most serious issues companies can face is the corruption of the Microsoft Exchange 2013 database file leading to unavailability of important data for the client. The Microsoft Exchange 2013 database can become vulnerable to crashes due to unavoidable hardware issues, software malfunctions, system freezes, server or boot failures, accidental shutdowns or any unforeseen circumstances. Since the last thing a company wants is to endanger business goals such as data availability during disasters, the first step is to make efforts to recover the damaged file.

How to configure a Multi-Resilient Volume on Windows Server 2016 using Storage Spaces

Plenty of articles have been released about Storage Spaces and everything around this topic. However, I would like to absorb all actual information and lead you through the journey of configuring Storage Spaces on a Standalone host. The main goal of the article is to show a Multi-Resilient Volume configuration process. In order to use Storage Spaces, we need to have faster (NVMe, SSD) and slower (HDD) devices. So, we have a set of NVMe devices along with SAS HDD or SATA HDD, and we should create performance and capacity tier respectively.

SMB Direct in a Windows Server 2016 Virtual Machine Experiment

Ever since Windows Server 2012 we have SMB Direct capabilities in the OS and Windows Server 2012 R2 added more use cases such as live migration for example. In Windows Server 2016, even more, workloads leverage SMB Direct, such as S2D and Storage Replication. SMB Direct leverages the RDMA capabilities of a NIC which delivers high throughput at low latency combined with CPU offloading to the NIC. The latter save CPU cycles for the other workloads on the hosts such as virtual machines.

Google Cloud Trying to Catch Up: NVIDIA GPUs and Discounts for Virtual Machines

We’ve reviewed several times about the large supremacy around AWS and Azure regarding cloud services market share (more details about recent surveys can be found here: “AWS Bigger in SMBs but Azure is the Service Most Likely to Renew or Purchase”) and Google Cloud lands in third place for most of the services.  Now they are implementing new NVIDIA GPUs for their virtual machines and sustained discounts for customers using the new NVIDIA VMs.

Hyperconvergence – another buzzword or the King of the Throne?

Before we have started our journey through the storage world, I would like to begin with a side note on what is hyperconverged infrastructure and which problems this cool word combination really solves. Folks who already took the grip on hyperconvergence can just skip the first paragraph where I’ll describe HCI components plus a backstory about this tech. Hyperconverged infrastructure (HCI) is a term coined by two great guys: Steve Chambers and Forrester Research (at least Wiki said so). They’ve created this word combination in order to describe a fully software-defined IT infrastructure that is capable of virtualizing all the components of conventional ‘hardware-defined’ systems.

Ceph-all-in-one

This article describes the deployment of a Ceph cluster in one instance or as it’s called “Ceph-all-in-one”. As you may know, Ceph is a unified Software-Defined Storage system designed for great performance, reliability, and scalability. With the help of Ceph, you can build an environment with the desired size. You can start with a one-node system and there are no limits in its sizing. I will show you how to build the Ceph cluster on top of one virtual machine (or instance). You should never use such scenario in production, only for testing purposes. The series of articles will guide you through the deployment and configuration of different Ceph cluster builds.

3 Generations of My Homelabs

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.

VMware vCenter Server Appliance Homelab tips

Many IT administrators or virtualization guys run their homelabs at home. It is a good way to learn new technologies, be able to break things in a lab to get stronger skills. It is sometimes a challenge, to squeeze as much RAM as possible from it. The main challenge is always a memory utilization. VMware VMs are getting memory hungry all the time and they are not “optimized” for Homelab use, but rather for production environments. Yes, it is the main purpose of those VMs after all.
