With the release of Windows Server 2016, Microsoft is introducing Storage Spaces Direct (S2D), which enables building highly available Software-Defined Storage systems with local attached storage. This storage can be leveraged by VMs running on the same cluster (in hyper-converged mode) or the storage can be presented as a File Share (in disaggregated mode). The hyper-converged deployment scenario has the Hyper-V (compute) and Storage Spaces Direct (storage) components on the same cluster. Virtual machine’s files are stored on local CSVs. Once Storage Spaces Direct is configured and the CSV volumes are available, configuring and provisioning Hyper-V is the same process and uses the same tools that you would use with any other Hyper-V deployment on a failover cluster.

Windows Server 2016 will be released the next month said Microsoft the last month. Windows Server 2016 brings a lot of new features compared to the last Windows Server version for Hyper-V, networking and storage. In this topic I will try to convince you to move from prior Windows Server edition to Windows Server 2016 with eight reasons.

Seagate shows off two new SSD products: an 8TB NVMe drive and a spacious 60TB SSD prototype in a 3.5-inch form factor.
This 60TB consists of more than a 1,000 Micron 3D NAND dice fitted into a full-size, 3.5-inch disk form factor package. Apparently, it has dual port 12Gbit/s SAS interface and 150,000 random read IOPS, with undisclosed write IOPS. The sequential read/write numbers should be 1.5 and 1.0GB/sec.

We will see how to install and use tools to manage your SQL Servers. We will use the version 13, who is compatible with Ubuntu. You can use these drivers from SQL Server 2008 to 2016, and it’s compatible with Azure SQL Database too.

Yesterday I saw a blog post in Homelab subreddit discussing what Intel NUC to choose. I have spent quite some time recently to choose the right server for my homelab expansion and I have considered a lot of options.
I was also looking at Intel NUC as many other fellow IT professionals, but luckily last month I read on Tinkertry.com that Supermicro had just released new Mini-1U SuperServers – SYS-E300-8D and SYS-E200-8D. I had some discussions with my colleagues and other people on Reddit and TinkerTry and I came to the conclusion that if you are aimed to run home lab for virtualization Intel NUC shouldn’t be considered. I believe SuperMicro is a new king on the market of mini servers for home lab.

A new feature called VHD Set for Hyper-V in Windows Server 2016 has been introduced by Microsoft. It allows sharing virtual hard disks between several servers in order to implement guest cluster easily without using complex technologies such as NPIV, virtual HBA, or virtual SAN.

VMware has long stopped adding newly released features and functionality into the old С# client in hopes to push their customers into using the vSphere Web Client. However, even by restricting new features only to the Web Client adoption has been slow – partly due to change, no one likes change, but mostly due to the slowness and the overall sluggishness that is experienced using the flash-based vSphere Web Client.

With the release of Windows Server 2016, Microsoft is introducing a new type of teaming approach called Switch Embedded Teaming (SET) which is a virtualization aware, how is that different from NIC Teaming (LBFO), the first part it is embedded into the Hyper-V virtual switch, that means a couple of things, the first one you don’t have any team interfaces anymore, you won’t be able to build anything extra on top of it, you can’t set property on the team because it’s part of the virtual switch, you set all the properties directly on the vSwitch. This is targeted to support Software Defined Networking (SDN) switch capabilities, it’s not a general purpose use everywhere teaming solution that NIC Teaming was intended to be. So this is specifically integrated with Packet Direct, Converged RDMA vNIC and SDN-QoS. It’s only supported when using the SDN-Extension.

New Server Management Tools (SMT) suite now on supports Windows Server 2012 and Windows Server 2012 R2, as it has been recently announced by Microsoft.
SMT includes a collection of well-known tools, such as Task Manager, Registry Editor, Event Viewer, Device Manager and Control Panel. Windows Update has been also added to that list few months ago. The difference is that now these tools actually are services housed in Microsoft’s Azure datacenters. Organizations must set up an on-premises gateway (which is called “server management gateway” by Microsoft) in order to use them.
“All SMT tools, except Windows Update and Device Manager, will now work with Windows Server 2012 R2 and 2012,”- Microsoft.

Microsoft Azure provides a way to deploy Azure VM from the Marketplace or from a generalized image. When you deploy the Azure VM from the Marketplace, no customization is deployed. You have to configure the operating system as your master. When you have several Azure VMs to deploy, the customization of each system can be time consuming. A lot of companies have a master or a baseline image in a VMDK for VMWare, in a VHD(X) for Hyper-V or in a WIM image. In this topic we will see how to create a generalized image from a single Azure VM and how to deploy Azure VM from this generalized image.
