Hi, we have a new Dell PowerEdge R540 and I'm looking for opinions on how best to configure the RAID(s). The system has 12 - 8TB SATA drives, PERC controller and has 512GB of RAM. The system will be a Hyper-V Host and will have many (probably a dozen or more) Hyper-V Virtual Machines on it. Some will be database servers like Oracle and SQL and others will be application servers and file servers. The OS will be Windows 2016. The VMs will be mostly 2016/2012 servers with a couple of W10 workstations sprinkled in. Interested in knowing how you would configure those drives. I usually like to use the hot spare option especially if the RAID only allows one drive failure. Years ago we had a RAID (5 I believe) with no hot spare and we lost two drives at the same time and all of our VMs … definitely would not want to go through that again. Thanks for your input.
