Data Management Moves to the Fore. Part 2: Data Management Has Many Moving Parts

In the previous blog, we established that there is a growing need to focus on Capacity Utilization Efficiency in order to “bend the cost curve” in storage.  Just balancing data placement across repositories (Capacity Allocation Efficiency) is insufficient to cope with the impact of data growth and generally poor management.  Only by placing data on infrastructure in a deliberative manner that optimizes data access and storage services and costs, can IT pros possibly cope with the coming data deluge anticipated by industry analysts.

vRealize Operations Manager Gems

Working with vRops over the last years has taught me one thing. The development of vRops goes so fast. Sometimes so fast that you do not realize when or what has changed. However, there are many “hidden” gems in vRops, which will make you and the product shine even more. So come along, as I will show you my top ten hidden gems of vRops…

Benchmarking Samsung NVMe SSD 960 EVO M.2

Everyone knows that, currently, the SSDs are one of the best storage devices that allow you to upgrade your architecture and significantly accelerate the performance of the computer. SSD accelerates the loading speed of your PC, applications opening and files searching speed, and generally increases the performance of your system. Despite the fact that solid-state drives are more expensive than standard hard drives, the performance improvement can hardly be overlooked.

Hyper-V Networking 101. Part 1: NICs and Switches

There are lots of posts regarding Hyper-V networking. But there doesn’t seem to be a single compiled and up to date guide covering fundamentals and some advanced topics alike. This article aims to fill that gap, without a wall of text but a few easy to understand diagrams, tables, and PowerShell snippets. We will take a look at Hyper-V’s basic networking concept, NIC teaming (Network Interface Card) and different approaches to let VMs (Virtual Machines) talk to specific VLANs or even VLAN trunks. The first article in the Hyper-V Networking 101 series will cover everything you need to know about virtual switches and NICs. The last post is planned as a real-world example: A way to implement a secure Wi-Fi (and/or wired) guest network on top of a virtual firewall.

Eliminating Blue Screen or Errors during failover

The reason for writing this post was a recent case from one of our customers, who ran into an issue when their SAN switch failed. The problem was that their VMs were generating an enormous amount of errors that were caused by the switching of active paths at the time of failover.

Microsoft Expands Olympus: Adds NVIDIA support

We’ve talked before in this blog about Microsoft Project Olympus and the Open Compute Project (OCP): “Microsoft, the Open Source Cloud Hardware and Why is it Important to You”. This time, Microsoft is expanding the Olympus ideal by adding NVIDIA support with their GPU capabilities into their Open Source Hardware.

RAM Disk technology: Performance Comparison

Since every computer now has a volatile amount of available storage located in the RAM, when compared to other direct-access memory used for data storage, for example, hard disks, CD-RWs, DVD-RWs and the older drum memory, the amount of time used to read/write the data differs in correspondence to the physical location and/or the medium used for reading/recording (rotation speeds and arm movement) the data. The implementation of RAM as a storage provides a list of benefits over other conventional devices, due to the fact of the data being read or written in the same amount of time irrespective of the physical location of data inside the volume. Taken into consideration all the information mentioned above, it would be a crime not to take advantage of the provided conditions.

Storage HA on the Cheap: Fixing Synology DiskStation flaky Performance with StarWind Free. Part 3 (Failover Duration)

We are continuing our set of articles dedicated to Synology’s DS916+ mid-range NAS units. Remember we don’t dispute the fact that Synology is capable of delivering a great set of NAS features. Instead of this, we are conducting a number of tests on a pair of DS916+ units to define if they can be utilized as a general-use primary production storage. In Part 1 we have tested the performance of DS916+ in different configurations and determined how to significantly increase the performance of a “dual” DS916+ setup by replacing the native Synology DSM HA Cluster with VSAN from StarWind Free.
