I have a new Dell PowerEdge T320 server with 1 SSD non-RAID and 3 HDDs in RAID 5 all on one Perc H310 controller. RAM is 48 GB and I have Windows Server 2012 R2 Data Center installed on the SSD.
I initially was attempting to create a VHDX on the RAID. The VHDX to create was of fixed size (over a 100 GB) and attempts to do that through the GUI and PowerShell both failed with I/O errors and crashes.
I then, in an attempt to find the problem, tried a simple copy and paste of a 50GB VHDX from the SSD to the RAID. That also caused a crash. I tried further to copy a large file (120 GB) created using fsutil from the SSD to RAID, again fail.
I read somewhere that there was a problem with large files and caching when using the default copy command, so I got a suggested tool "terracopy" which has the option (default) to have system write cache disabled. That went on copying for some time before I decided to stop it since it seemed to be working.
My main need is to create a large VHDX, does anyone have a clue what is going on?
Edit: Additional details:
- Ran Diagnostics, did not yeild anything useful.
- Dell replaced the RAID controller, no change.
- Installed Windows 8 to test the copy and paste, it went on copying for a relatively long time before I stopped it since it looked like there would be no crash.
- Booted from Linux Puppy USB, did a copy paste of a 120GB file from the SSD to the RAID, no issues.
