New cluster model for Windows 2019 allows router USB to be used as witness node

Cluster arbitration needs a third computer hosting a share folder as judge to facilitate automatic failover between two computers hosting high available service.

However it was costly to have one. It must be joined to domain, must not be a domain controller and must not be down and can't be in DMZ as domain authentication must also succeed.

That is really easy on hardware and software. Good News is MS Windows Server 2019 remove ALL! of these requirements.

This means NO kerberos , NO domain controller , NO certificates , and NO Cluster Name Object needed. While we are at it, NO account needed on the nodes. Oh my!!

Just use even your router's USB share to arbitrate your internal clusters !!!!

Now it does make a lot of sense to use your cloud machine to arbitrate your internal on premise cluster setups!!!

Just need that atleast SMB 2.0 level file sharing is supported by your shares.

Inventory your Servers using PowerShell

Inventory your servers is very time taking task, most the methods to automate collecting inventory information cannot fetch detailed BIOS information and MAC Address.

With powershell and WMI, I've contributed a script that additionally queries and tag that information as well. Details will include BIOS details, Serial number, Platform as well.

Output sample:

SQL Always-On - Choose between Async vs Sync Replication mode.

SQL Always-ON is great technology. Often times architects and decision makes get stuck on a model of replication to decide in it. Confusion arises from the fact that it provides two flavors of replication: synchronous as well as asynchronous. Both approaches come with pros and cos.

Just to settle the confusion and reference for all decision makes and architects, I've documented the MS Article available at below MS Link:
