Educational Episodes: Hyperconverged Infrastructure (HCI)

Regarding the growing demand on the cloud, it’s no problem finding a cloud storage provider. However, there are only few market players that can be considered true leaders of this industry. Amazon is one of these guys, with S3 cloud storage serving a perfect fit for any business regardless of its size. But still, even Amazon’s customers face several challenges during data migration process to S3, especially, when it comes to petabytes.

Now that VMware vSphere 6.7 has been announced and it’s also available in General Availability (GA), some people may ask if it makes sense upgrade to this version (or when will make sense upgrade to 6.7). Is a GA release ready for a production environment? Or is it mature and stable enough?

Protection Groups is a new feature introduced with the Update 3 of Veeam Backup & Replication 9.5 and allows the administrators to backup physical servers and workstations through the use of Agents.

Recently, I decided to automate some boring routine procedures related to setting up virtual networks in ESXi 6.5. That’s right, I’m talking about PowerCLI. This command-line tools allows automating all aspects of vSphere management, including network, storage, VM and so on and so forth. Sure, I had to dig into the details of orchestrating ESXi with PowerCLI. Yep, it took me some time but at the end of the day, the knowledge and experience I acquired paid back! Apparently, this case is not unique, so I decided to share my experience in today’s scribbling.

PowerShell is a command line (CLI) scripting language developed by Microsoft to simplify automation and configuration management, consisting of a command-line shell and associated scripting language. It’s a (huge) evolution (or better a revolution) from the original DOS batch language (still supported in latest Windows OS with the cmd.exe command), and it’s really better compared to the different previous attempts to replace the batch language (like Windows Script Host).

We live in an age where our technology needs are ever evolving. Right now we may need things we didn’t even know existed until a few weeks back because every little feature or upgrade brings massive value into our everyday lives. The same is the case with the preview release of Microsoft  Windows Server 2019. Let’s take a closer peek at what features Microsoft has in store to serve our evolving needs with its new release.

The RDMA wars in regards to SMB Direct: RoCE versus iWarp.

While updating VMware ESXi servers, VMware vSphere users may encounter the “No space left on device” error that pops up while executing the “esxcli software vib update” command. Interestingly, the problem occurs even though disks are doing well and have enough free space and df -h command proves that.
