VMware vSphere 6.7 Network I/O Control – getting under the hood

If you are a VMware vSphere administrator who wants to solve the problem of a low network throughput, Network I/O Control (NIOC) is exactly what you need! It’s a traffic-specific vSphere Distributed Switch (vDS) mechanism of network bandwidth regulation that was firstly introduced in vSphere 4.1 in 2010. NIOC appeared when 10G networking was increasingly prevalent and became a real breakthrough. With this mechanism, you can ensure high network throughput and go with fewer network adapters in ESXi hosts. That sounds pretty good, doesn’t it?

Complete an infrastructure project for your organization with iSCSI SAN

IT administrators are always confronted with the problem of building innovative, fast, modern, and reliable IT infrastructure that fits the budget and saves resources for future growth. To commence, you should plan, select, re-plan, clarify goals, and so on ad infinitum in a vicious circle. However, the issue of guaranteeing the data safety will always be relevant on the agenda. Choosing a SAN (Storage Area Network) with the iSCSI protocol as one of the possible storage solutions will ensure data security and constant availability. In addition, this approach is cost-effective in terms of maintenance and support.

Log-structured Write-Back Cache – forget about post-blackout full syncs

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.

Windows Server 2019 introduces a new SMB Mapping Option UseWriteThrough

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!
