Educational Episodes: Hyperconverged Infrastructure (HCI)

Let’s imagine a situation: a power outage went out and an incorrect server shutdown has occurred. Everything is aggravated by the fact that you have no power backup. What will happen to your write operations? They sink into oblivion and data will be lost. But StarWind says “no” to these troubles! Log-structured Write-Back Cache (LSWBC) is a StarWind feature which speeds up the processing of write requests and saves data when the server is incorrectly shut down. What about RAM caching? Your data also will be saved.

Do you know that not every solution requires high available storage? Sometimes there is a need in functionality that gives us the option not to leverage any OS caching. Precisely this UseWriteThrough option you can find in the New-SBMMapping commandlet in Windows Server 2019. It allows a user to disable caching with SMB mappings in certain scenarios thus giving a possibility to prefer reliability over performance in non-continuously available file share scenarios. So, always check “paper proof of concepts” and find the best options for your IT infrastructure and business development!

One, two, three … Let’s roll! StarWind presents an updated functionality of V2V Converter. The utility enables conversion of a physical machine into a virtual one (P2V) and other way around. For example, you have a server with Windows Server 2012R2 installed running some critical application. With physical-to-virtual (P2V) entire host or specific physical drive (or volume) can be migrated. What else? The pressure is on! Now your VMs can be migrated directly between Hyper-V and ESXi (and backwards). Moreover, StarWind V2V Converter offers bi-directional conversion between all the major VM formats: VMDK, VHD/VHDX (Windows Repair Mode aware), QCOW2, and StarWind native IMG.

VPN connections provide remote access to the necessary data and you can get information about your company’s assets at any time. The connection to Azure virtual networks is possible by configuring two types of VPN, namely Site-To-Site (S2S) and Point-To-Site (P2S). S2S VPN allows you to connect two networks and constantly maintain communication between them. P2S VPN is effective for connecting to a virtual network from a remote location if you have a small number of clients for whom such an access is needed. You’re asking how to establish a secure connection of individual clients running Windows 10 to the Azure Virtual Network?

VMware vSphere 6 offers all new and new features including a new VMware vCenter management services architecture. vCenter 6.0 can be deployed in embedded and external options and separately as a Platform Services Controller (PSC) and as vCenter. If the Platform Services Controller (PSC) provides common infrastructure services for the data center, then the vCenter Server ensures the remainder of the vCenter Server functionality. But you’ll agree, it would be great to have a common platform that combines both solutions. This option would help reduce the number of VMs per sites without any load balanced dependencies and provide fault tolerance.

Migrating sites to the cloud can be quite troublesome. For such cases, Microsoft introduced the Windows Site Migration Tool. This is a program that can collect the necessary information about a website hosted on IIS, analyze it, and then automatically transfer all settings, files, and even the database directly to the Microsoft Azure cloud. Make sure that the migration of the sites is really easy and can be completed within a few minutes!

The latest technology allows moving as separate databases and log files and the entire system. In this context, speed, ease, and lack of downtime are critical factors for the success of this process. How to ensure them and not to get lost in a variety of options for migrating SQL Server databases to Azure?

StarWind & VMware vSphere users get unrestricted VSAN from StarWind features, storage capacity, and outstanding cost-efficiency. Using StarWind VSAN, the process of deploying VMs, providing fault-tolerant storage, connecting it to hypervisor, and creating highly available VMs becomes a “piece o’ cake!”. But what about software RAID configuration? How not to get lost in a variety of choices between the different RAID levels?

Everyone knows that modern operating systems write data into the empty blocks but not in the ones that are just marked as deleted. VMware vSAN 6.7 Update 1, TRIM/UNMAP feature to be exact, will help you to easily restore data that marked as deleted. For space-saving concerns, vSAN allows creating thin provisioned disks that grow gradually as they are filled with data.
