Currently am trying to upgrade an iSCSI shared storage server for a SQL Server cluster (server is running Windows Server 2012, I plan on upgrading that at a later time). After looking at where to get big wins in hardware I was excited to see the insane access times and IOPS of the Optane 900p SSD's. They market them for gamers, but they're definitely more suited for high IO workloads like databases. I know you can RAID 1 these via Intel's VROC, which requires a specific chipset, which this server doesn't have. So, I figured I can just do a Windows RAID 1. Here is where I run into issues:
- Both drives are recognized in Disk Management.
- Windows Server Storage Manager sees both drives, but only one drive can be added to a storage pool.
- Using the older method of a dynamic disk mirroring in Disk Management works, as it allows me to setup the mirror but it will instantly fail with the error 'failed redundancy.' In this case in event viewer I see a message 'Extent Disk2-01 on disk {id here} that is part of the fault-tolerant volume D: is no longer accessible'
I have tested each drive separately for faults, including software that tests each sector as well as writing to the entire drive and testing for corruption. Nothing says either drive is bad. Worst case I'm thinking I can simply do some block level file mirroring software to mirror the VHD files across the drives, but obviously you won't get the up time benefit of a mirrored RAID. Anyone have any ideas of why this is happening and/or potential fixes?
