How to use a persistent memory disk in a Hyper-V virtual machine

Probably, everyone asked that question when finding out about the support function for persistent memory disks inside a virtual machine (VM) in Windows Server 2019 with the Hyper-V role. Persistent memory disks are good when we need a very high speed and very low latency. Some vendors can provide persistent memory disk option for you in their storage offerings. But why mapping persistent memory storage via the hypervisor host is so important?

Is Microsoft really considering an acquisition of Mellanox?

Mellanox, an Israeli company, is a leader when it comes to FPGAs and all kinds of programmable logic in the switches and NICs. The latter allow having 25Gbps at a cost and quality level traditional network companies won’t allow. Recently rumors about an acquisition of Mellanox by Microsoft began to circulate. The only decision assessment does not exist, as well as the determination of reasons for which Microsoft decided to take this move. Why does Microsoft want to buy Mellanox?

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!

Does low latency, high throughput & CPU offloading require RDMA?

Does low latency, high throughput & CPU offloading require RDMA? What? Blasphemy, how dare we even question this? In my defense, I’m not questioning anything. I am merely being curious. I’m the inquisitive kind. The need for RDMA is the premise that we have been working with ever since RDMA became available outside of HPC InfiniBand fabrics. For us working in the Windows ecosystem this was with SMB Direct. Windows Server 2012 was the OS version that introduced us to SMB Direct, which leverages RDMA.

Replacing a Veeam Agent for Windows host while preserving existing local or share backups

Imagine you have a server with data source volumes that are backed up to local (or a share) target backup volumes with Veeam Agent for Windows (VAW). You might or might not backup the OS as well. That server is old, has issues or has crashed beyond repair and needs to be replaced. You don’t really care all that much about the server OS potentially but you do care about your data backup history! You don’t want to lose all those restore points. Basically, we try to answer how do you replace the backup server when it’s a local Veeam Agent for Windows 2.1 deployment.

Using a VEEAM off-host backup proxy server for backing up Windows Server 2016 Hyper-V Hosts

Many years ago, I wrote a white paper on how to configure a VEEAM Off-host backup proxy server for backing up a Windows Server 2012 R2 Hyper-V cluster that uses a hardware VSS provider with VEEAM Backup & Replication 7.0.  It has aged well and you can still use it as a guide to set it all up. But in this article, I revisit the use of a hardware VSS provider dedicated specifically to some changes in Windows Server 2016 and its use by Veeam Backup & Replication v9.5 or later. The information here is valid for any good hardware VSS provider like the one StarWind Virtual SAN provides (see Do I need StarWind Hardware VSS provider?)
