Thanks for the replies. It turned out to be the SAS3 HBA. I swapped it out and those errors seem to be fixed. I'm running some more tests to be sure but it looks good so far. Thanks again.

I have 2 (new to me) 2U Supermicro servers and 12 Ultrastar HE10 10TB SATA drives. Before I put any data on used drives I always test them with HD Sentinel using the surface test Write + read destructive. Server 1, 6 HDD's completed the write tests with good speeds and no issues but on the read...

Hi, I'm building a 2 server hyper converged system with server 2022 and all I have left to purchase is the fast tiered SSD's. I was going to buy Intel P4610's for that but they are not listed as SDDC certified for server 2022. I tried this previously using server 2016 but windows didn't like...

Thank you!

I hope this isn't too stupid of a post but I'm a bit lost and could use a nudge in the right direction. I just bought a pair of server that use a X11DPU motherboard and I'm confused about which CPU's can be used in it. For some stupid reason there isn't a published CPU compatibility list or...

I followed the guide by dodgy route to convert my EMC switch to an SX6018 and all seems to be good except that the web interface is terribly slow. The CPU usage is between 40% and 100% with nothing going on. I saw the below comments and when I tried the "mlxi2c update_bootstrap166" command I...

Has anybody had any experience with a 7 node S2D using parity? I have not been able to find any sort of comparative benchmarks on the read performance vs what a single server with Storage Spaces and drives in parity. I have 45x 10TB drives in a dual parity setup with journal drives on WS2019...

Sadly no. I should have tried a Multi-Resilient Volume with the HDD's making up both tiers. I have done it before and it worked ok.

Thing to note is that's only for Storage Spaces Direct which is only on the DC edition of server and is for clusters.

As far as I can figure, Storage Spaces will not use the fast tier (SSD) if the fast tier is below a particular percentage (~3.2%) of the total size of the virtual drive. This is a PITA because 1TB of a fast tier with a large dual parity capacity tier still speeds up large writes nicely. The...

I figured out my problem. The Performance tier (SSD) is smaller than the free space threshold that triggers the writes to land directly on the HDD's. I'm reasonably sure it's configured as a % of the total volume. When I created the volume with a capacity tier of 600GB instead of 300TB the...

I setup a tiered storage space with 45x 10TB drives and 3x NVMe 1.6TB SS's. The writes were slow and looking into it a bit it seems the writes all land on the slow tier instead of the fast tier. I have tried with ReFS and NTFS and the results are the same. Any suggestions?

A bit late to the party but for the same type of setup I used a GTX 1660 so the quality of the transcodes wouldn't suffer as the NVENC is Turing based which has addressed the quality degradation of previous generations. It took a bit of messing around but I have it working with the 2 stream cap...

I destroyed the storage pool, rebooted and started again but the results seem to be the same. I had changed the cluster size from 512 to 4096 on the SSD before I put them into a pool but I don't think I rebooted after so I thought maybe a reboot and rebuild would fix it. Nope. I noticed...

I could really use some help. I try hard not to bother other people when there is a possibility that if I keep working on an issue I'll sort it out myself which is why I was a lurker here for so long before posting. I have hit a wall with this storage space and the performance is much lower...
