Updated in Mar 2023: Ignore the May 2022 update, I was right all along. Microsoft actually change the default VMQ in Azure Stack HCI deployments, so that says all I need to know.
**** ALWAYS change base processor to core 2 (or 1 if HT is not enabled) **** Updated in May 2022: For about a year or so now since MS made some tweaks and a growing confidence in the out of the box settings, the optimal position has changed on WS2019.
Excited to be speaking at Microsoft Ignite The Tour in Sydney. For those coming along, below are my sessions and demo times slotsā¦ If you see me make sure you come up and say hi!

The question: To enable or disable CSV balancer in S2D?
Before we continue, I want to clarify the Cluster AutoBalancer and CSV Balancer are separate things.
Cluster Autobalancer is relating to cluster roles, or in this case the VMās. CSV balancer is about the CSV storage.
Info on each can be found here: Cluster Autobalancer aka VM Load balancing:Ā Clustering and High-Availability CSV Balancer, i.e. what we are talking about here:Ā Automatic SMB Scale-Out Rebalancing (this is related to SOFS and 2012R2 but gets the info across)
WORK IN PROGRESS Editors Note: this is still a working document as my priorities have to be on other work right now, but in the interest of sharing I have made this available nowā¦ If you find any issues or errors let me know - thanks for reading!
There are many S2D build blogs out there and I donāt want to just add to the list but given Iām doing this build with SCVMM and SCOM integration I thought Iād run through the additional steps.
A few months ago we placed an order for some slick HPE Gen10 hardware to replace our existing storage service. Our trusty Server 2012 R2 Storage Spaces with DL360 Gen8ās and DataON enclosures has served us well, very well, but itās time to move on to the latest and greatestā¦
āThe SANKillerā
At the time of writing this (10 of April 2018),Ā although theyāve very recently added 2 more SFF configs, HPE have not published a WSSD certified solution for Gen10 LFF chassis.
An interesting solution brief of Hyper-Converged Infrastructure from DataOnĀ got my cogs ticking on a topic that has bugged me for a whileā¦ All-Flash storage.
Firstly, this DataON solution is a seriously slick contenderā¦ a 3M IOPS 4-node HCI in 8U. The tech geek in me would be quite pleased to have that bad boy driving services on my platform.
But is it necessary?
Ultimately, that is a question that only you can answer based on your requirements, but after deploying several Hyper-Converged Infrastructure (HCI) and Storage Spaces Direct (S2D) solutions from various vendorsĀ over the last 12 months, I wanted to share my thoughts on this All-Flash phenomenon.
How many mirrors?
Over the past few months weāve deployed several Storage Spaces Direct solutions, and one question that seems to pop up is the expected performance difference for a 2-way mirror vs a 3-way mirror. The obvious answer is a 2-way will out-perform a 3-way, but by how much?
I wonāt go into the resiliency or design decisions or when either option is preferred, this is purely from a performance based perspective.
