Blatant advertising of app. Edited it down. It okay to put apps in here but not a lengthy adverstisement of apps.

      Hi all,
       
      Here's a guide I would like to share around Windows Storage spaces and creating a 4x drive Parity pool
       
      In a nutshell I have Windows Serer 2019 and storage space parity pool running very nicely on my Gen8. Here's the configuration I used and How to copy my setup.
      (I still believe ZFS or UnRAID are far better choice as a filesystem on these limited servers, but if you need Windows like I do, then storage spaces can be an excellent alternative.)
       
      This is my "best effort" guide and by no means perfect. It does however yield excellent results for both read and write speeds.
       
      Gen8 Microserver
      16GB RAM
      CPU Stock for now (1270 V3 on it's way)
      Disks  4x 3TB WD NAS drives in front bays
      SSD - Samsung Evo 850 265
       
       
      First lesson, DONT use the Windows GUI to create the pool or Virtual disk as the GUI applies terrible defaults that you can't edit and will ruin performance. Also make sure you're on the latest version of Windows server as a LOT has changed and been improved recently.
       
       
      You must use PowerShell.
       
       
      Terms:
      PhysicalDiskRedundancy - Parity Columns - 4 (The data segments stripped to disks. Should match your 4 disks) Interleve - 256K (The amound of data written to each "column" or disk. In this case 256KB interleave gives us a 64K write to each disk) LogicalSectorSize - 4096 PhysicalSectorSize - 4096 REFS/NTFS Cluster - 64K  
       
      Overall configuration:
      4 drive file system, one bootable SSD in RAID mode.
       
      BIOS setup initial
      F9 into the BIOS and set the B120i controller into RAID mode
      F5 into the RAID manager and create 1 individual RAID0 logical drive for the SSD
      Set the SSD as the preferred boot drive (Yes in the same screen)
      Set the cluster size to 63
      Enable caching
       
      Windows install 
      Install Windows 2019 Server Standard GUI edition from ISO
      Offer up the B120i RAID drivers via a USB stick so the wizard can see the SSD RAID0 drive. Filename p033111.exe (Have them extracted)
      Windows update and patch and reboot
       
      BIOS setup post windows
      Once windows is up and running go back into the F5 RAID manager and finish the setup of the 4 front drives into 4x RAID0
      Check the SSD is still set as the preferred boot drive (Yes in the same screen)
      Set the cluster size to 63
       
      Windows config of storage spaces
      At this point you should see 4 individual drives ready to be used as a Storage pool
       
      Try to set each disk to have a cache (Not all drives support this)
      Win + X to open the side menu
      Device Manager
      Expand Disk Drives
      Right Click the "HP Logical Volume" for each drive
      Check - "Enable write caching on the device"
      (If it doesn't work don't stress, it's optional but nice to have)
       
       
      Powershell - Run as Admin
       
      Determine the physical drisks available for the pool we're about to create
      Get-PhysicalDisk | ft friendlyname, uniqueid, mediatype, size -auto  
      Your output will look something like this, so identify the 4 drives that are the same and take note of their uniqueID
       
      Mine are the bottom four drives all 3TB in size
       
      friendlyname            uniqueid                                        size
      ------------                         --------                                        ----
      SSD
      HP LOGICAL VOLUME       600508B1001C5C7A1716CCDD5A706248        250023444480
       
      HP LOGICAL VOLUME       600508B1001CAC8AFB32EE6C88C5530D       3000559427584
      HP LOGICAL VOLUME       600508B1001C51F9E0FF399C742F83A6       3000559427584
      HP LOGICAL VOLUME       600508B1001C2FA8F3E8856A2BF094A0       3000559427584
      HP LOGICAL VOLUME       600508B1001CDBCE168F371E1E5AAA23       3000559427584
       

      Rename the friendly name based on the UniqueID from above and set to "HDD type"
       
      Set-Physicaldisk -uniqueid "Your UniqueID" -newFriendlyname Disk1 -mediatype HDD
       
      You will need to run that 4 times with each UniqueID code and create a new friendly name for each drive. I called mine "Drive 1, Drive 2" etc
      Set-Physicaldisk -uniqueid "600508B1001C2FA8F3E8856A2BF094A0" -newFriendlyname Disk1 -mediatype HDD Set-Physicaldisk -uniqueid "600508B1001CDBCE168F371E1E5AAA23" -newFriendlyname Disk2 -mediatype HDD Set-Physicaldisk -uniqueid "600508B1001CAC8AFB32EE6C88C5530D" -newFriendlyname Disk3 -mediatype HDD Set-Physicaldisk -uniqueid "600508B1001C51F9E0FF399C742F83A6" -newFriendlyname Disk4 -mediatype HDD  
      Verify the disks have been set correctly
      The following example shows which physical disks are available in the primordial server and CAN be used in the new Pool. You're just checking here if the friendly name renaming worked and they are all set to HDD type. Primordial just means on your local server and available.
      Get-StoragePool -IsPrimordial $true | Get-PhysicalDisk | Where-Object CanPool -eq $True You should see your four drives with nice names that you set like "Disk1"
       
       
      Now find out your sub system name, as we need this for the next command. Just take note of it. Example "Windows Storage on <servername>"
       
      Mine is ""Windows Storage on Radaxian"
      Get-StorageSubSystem  
       
      The following example creates a new storage pool named "Pool1" that uses all available disks and sets the cluster size.
      New-StoragePool -FriendlyName Pool1 -StorageSubsystemFriendlyName "Windows Storage on Radaxian" -PhysicalDisks (Get-PhysicalDisk -CanPool $True) -LogicalSectorSizeDefault 64KB  
       
      Now create the Virtual Disk on the new pool with 4x disks and Partity set correctly. (This is critical to do via PowerShell)
      New-VirtualDisk -StoragePoolFriendlyName "Pool1" -FriendlyName "VDisk1" -ResiliencySettingName Parity -NumberOfDataCopies 1 -NumberOfColumns 4 -ProvisioningType Fixed -Interleave 256KB -UseMaximumSize Those two commands should complete without error, if they don't go back and check your syntax
       
       
       
      Go back into the Windows GUI and open this
      Server Manager\File and Storage Services\Servers
      You should see the Storage pool listed and the Virtual disk we created in the previous steps.
       
      Storage pool - Pool1
      Virtual Disk - VDisk1
       
      Select Disks in the GUI
      Identify your new VDisk1 and right click it.
      Set to Online, this will also set it to use a GPT boot record
       
      On the same screen in the below pane Volumes
      Click TASKS and select "New Volume"
      Select REFS and Sector size of 64K
      Enter a volume name like "Volume1" or whatever you want to call it
      Select a drive letter such as Z
      (You can use NTFS here for slightly better performance, but I'm sticking to REFS as it has some benefits)
       
      You'll now have a Storage pool, Virtual disk on top and a volume created with optimal settings
       
       
       
      Go back into Power Shell
      Enable power protected status if applicable (Just try it, no harm)
      (Ideally here you should have your server connected to a basic UPS to protect it from power outages)
      Set-StoragePool -FriendlyName Pool1 -IsPowerProtected $True  
      Check if the new sector sizes of Virtual disk and all relevant settings are correct
      Get-VirtualDisk | ft FriendlyName, ResiliencySettingName, NumberOfColumns, Interleave, PhysicalDiskRedundancy, LogicalSectorSize, PhysicalSectorSize Example output
      FriendlyName  ResiliencySettingName  NumberOfColumns  Interleave  PhysicalDiskRedundancy  LogicalSectorSize  PhysicalSectorSize
      VDisk1                Parity                                      4                       262144                         1                                        4096                       4096
       
       
      You're done.... enjoy the new Volume.
       
      At this point you can share out your new Volume "Z" and allow client computers to connect.
       
       
       
       
      Some other commands in Power Shell that I found useful
       
      Get more verbose disk details around sectors.
      Get-VirtualDisk -friendlyname Vdisk1 | fl  
      Get-PhysicalDisk | select FriendlyName, Manufacturer, Model, PhysicalSectorSize, LogicalSectorSize | ft  
       
      Check if TRIM is enabled. This output should be 0
      fsutil behavior query DisableDeleteNotify If TRIM is not enabled, you can set it on with these commands
      fsutil behavior set disabledeletenotify ReFS 0 fsutil behavior set disabledeletenotify NTFS 0  
       
      Check the Power Protected status and cache
      Get-StorageAdvancedProperty -PhysicalDisk (Get-PhysicalDisk)[0]  
       
      Once your data has been migrated back to your new pool from backup, make sure you run this command to "spread out the data" properly.
      This command rebalances the Spaces allocation for all of the Spaces in the pool named SQLPool.
      Optimize-StoragePool -FriendlyName "Pool1"  
       
      I'm yet to get my Xeon in the mail, but once that's installed I think the disk performance will go up even higher as the stock CPU is junk.

      The SDM R4 is SOLD OUT!
       
       
      The SDM R4 is a bracket that facilitates mounting two additional 2.5″ drives in a HP MicroServer Gen8. There are also mounting holes for fans across the bottom to help cool RAID/SATA cards. The kit includes all the fasteners needed to install.
       
      With optional Stackers you can run four 2.5″ drives on the SDM R4. The SDM R4 will support four 9.5MM 2.5″ drives. If you want to run four drives on the SDM R4, you need to order SSB stacking brackets listed below. One set of SSB per drive pair, four drives will require two SSB kits. Because of the size of the SDM R4, if you are going to boot your server using the internal USB port, you will need to use a USB stick that is shorter than 1″.

      Hi Community,
       
      First, my specs (briefly):
      MicroServer Gen10
      AMD Opteron X3216
      Win Server 2016
      [...]
       
      Problem:
      The Taskmanager shows only 1 CPU-core instead of 2.
      (ref. image 1)
       
      Solutions tried:
      checked msconfig...no CPU-Limit set checked, whether other users see the same amount of CPU-cores in task-manager (ref. image-link (internal) 2)  
      Anyone out there with an idea to solve this?
       
      Greets
      Henrik
