The Need For Liquidity in Data Storage Infrastructure

Liquidity is a term you are more likely to hear on a financial news channel than at a technology trade show.  As an investment-related term, liquidity refers the amount of capital available to banks and businesses and to how readily it can be used.  Assets that can be converted quickly to cash (preferably with minimal loss in value) in order to meet immediate and short term obligations are considered “liquid.” When it comes to data storage, liquid storage assets can be viewed as those that can be allocated to virtually any workload at any time without compromising performance, cost-efficiency/manageability, resiliency, or scalability.  High liquidity storage supports any workload operating under any OS, hypervisor, or container technology, accessed via any protocol (network file systems, object storage, block network, etc.), without sacrificing data protection, capacity scaling, or performance optimization.

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.

Disaster Recovery and why hypervisor HA may not be best

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”.

StarWind Cloud VTL for AWS and Veeam

These days, almost every company that stores its own data on-premise, will it be the virtual machines, databases or just plain files, needs to be sure that this data won’t be lost due to some accident or human error. More to say, backup solutions are usually requested to be flexible, feature-rich and utilize different storage-optimization technologies for increased cost-efficiency. The additional requirement of the long-term data retention significantly increases the overall cost of the final solution, which resulted in an increased demand for public clouds like Amazon Web Services and Azure as a backup repository for their data.

Azure Stack in GA. Part II: Deployment Models and How Much is Going to Cost

I’ve recently covered in my previous post about Azure Stack being finally released to the Integration Systems (Dell EMC, HPE and Lenovo). We covered in the article the clarification of what Azure Stack actually means, features and functionalities available. In this second part will go beyond, reviewing how much is going to cost, deployment alternatives, Azure integration, and the disconnected scenario.

Free SMB3 Failover File Server on Microsoft Hyper-V Server 2016

In the previous article, we have created a free SMB3 file server. I decided to proceed with the testing of Microsoft Server Hyper-V 2016 free version possibilities. In this post, I will try to create Highly Available devices with VSAN from StarWind and then create a Microsoft Failover Cluster to make a Highly Available File Server. We are using 2 servers with Microsoft Hyper-V 2016 added into a domain (Hyper-V-1; Hyper-V-2). Client node with Windows Server 2016 (2016-client-test).

How to join VMware vCenter server appliance (VCSA) 6.5 to the Microsoft Active Directory (AD) Domain

VMware Photon OS has been the latest OS used for vCenter Server Appliance 6.5. This is the latest move from SUSE Linux Enterprise Server (SLES) as VMware wants to own the Operating system (OS) and manage its development cycles and patches releases. Things that aren’t possible on Windows OS or SLES. That’s why VMware used Photon Linux and continues to develop Photon OS which is optimized for VMware platforms.

Free SMB3 File Server on Hyper-V 2016

This series of articles will guide you through creating a free SMB 3.0 file server in Microsoft Windows Hyper-V 2016. Hyper-V 2016 is an absolutely free GUI-less version of Microsoft Windows Server for virtual machines. Hyper-V 2016 Server has been specifically developed and created only for virtual machines. According to Microsoft EULA, StarWind does not recommend repeating the steps below, because this process is a violation of the license agreement. The reason why we can create SMB File Share on Hyper-V 2016 is simple: all Windows servers require SMB 1/2/3 to work, and Hyper-V 2016 is not an exception. But it does not mean you should create any unsupported Microsoft services on GUI-less Hyper-V 2016.
