  1. you can recover sa, no problem, here is a tutorial I prefere the second method (Command line) https://www.wikihow.com/Reset-SA-Password-in-Sql-Server
  2. H730 is good enough for a raid 5 or 6 for windows server, just make sure that if all your drives are mechanical that you leave cache enabled (Defult values should be ok) but if you are using SSDs disable write cache and put it in passthrough mode.
  3. What are you exactly wanting to do? just data protection? I mean depending on what PERC you R730 has.... that could be a good idea or atleast a much more simpler one. You have all your firmwares in the latest version, correct?
  4. Nope... I mean servers as in server nodes. S2D hyperconverged infrastructure in Windows server depends of the number of servers which should have similar (same preferred) hard drive configurations.
  5. Um... Storage Spaces is about providing fault tolerance, often called 'resiliency', for your data. Its implementation is similar to RAID, except distributed across servers and implemented in software. Single parity keeps only one bitwise parity symbol, which provides fault tolerance against only one failure at a time. It most closely resembles RAID-5. To use single parity, you need at least three hardware fault domains – with Storage Spaces Direct, that means three servers. Because three-way mirroring provides more fault tolerance at the same scale, we discourage using single parity. Dual parity implements Reed-Solomon error-correcting codes to keep two bitwise parity symbols, thereby providing the same fault tolerance as three-way mirroring (i.e. up to two failures at once), but with better storage efficiency. It most closely resembles RAID-6. To use dual parity, you need at least four hardware fault domains – with Storage Spaces Direct, that means four servers. Resiliency Minimum required fault domains Two-way mirror 2 Three-way mirror 3 Dual parity 4 Mixed 4
  6. 1) what about in your network switch? was the jumbo frames configuration applied there as well? 2) the machines you used for testing, are they in separate hosts? are they in the same host? would you care to draw a simple diagram of your infrastructure and post it? would be easier to troubleshoot
  7. Have you tried booting your server in safe mode?
  8. Just a "control" question... if you have 2VMs in the same host and assigned to the same virtual switch, if you do an iperf3 test...whats the speed you are getting? Is it superior to 10Gbps? Oh! and another thing! you did configue jumbo frames on your physical switches and virtual switches besides your host OS, correct?
  9. You could use the lifecycle controller to do the update of all your hardware just point it to ftp.dell.com (I can confirm this method still works) https://www.dell.com/support/article/us/en/04/sln292343/poweredge-server-lifecycle-controller-update?lang=en Also when installing an OS in Dell servers always do it through lifecycle controller as it will preload all the recommended drivers for you (this is wy its important to keep all the driver packages/firmwares up to date. (Except for ESXi, that is reccommended to be done with the Dell custom ESX image). Protip: Dont forget to first assign an IP address to the lifecycle controller adapter so it can go out to ftp.dell.com when doing the upgrade through lifecycle controller.
  10. 1) (you surely must have this but Ill put it anyways) make sure you are running latest virtual hardware version supported by your vmware version and latest vmware tools installed. 2) You may need to disable LRO in a VMXNET3 network adapter. On Windows, the LRO technology is also referred to as Receive Side Coalescing (RSC). For more information search Microsoft help for how to Enable or Disable LRO on a VMXNET3 Adapter on a Windows Virtual Machine. https://kb.vmware.com/s/article/2129176 Let me know how it goes, Ive seen this before, mainly when dealing with SQL Server VMs.
  11. Glad you had success. Mirror is 50% capacity loss, Parity space loss is similar to a raid 5 configuration
  12. Hey man, my apologies, I've been busier than expected all this year... Congrats on the advances, I'll figure out the command for parity when I get home. Ssd and HDD always go in the same pool for a hybrid build, so I would discard 100% having to separate them.
  13. My best advice is to do it through PowerShell (ISE) with admin priviledges, you can autocomplete an see the suggestions for the commands there. If you have spare time let me know through a PM and we can do a remote session, Ill give you a hand.
  14. When you create the separate NAS network dont forget to add the route https://www.howtogeek.com/howto/windows/adding-a-tcpip-route-to-the-windows-routing-table/
