I have one Dell PowerEdge R640 server contains 8 disk NVMe. the server will use high i/os. what's the recommendation for create RAID? thanks for helping.
RAID0 for high throughput but no redundancy.You may consider RAID 10 or RAID 5
●RAID 0 uses disk striping to provide high data throughput, especially for large files in an environment that requires no data redundancy.
●RAID 1 uses disk mirroring so that data written to one physical disk is simultaneously written to another physical disk. RAID 1 is good for small databases or other applications that require small capacity and complete data redundancy.
●RAID 5 uses disk striping and parity data across all physical disks (distributed parity) to provide high data throughput and data redundancy, especially for small random access.
●RAID 10 is a combination of RAID 0 and RAID 1, uses disk striping across mirrored disks. It provides high data throughput and complete data redundancy.
You would be using S140 controller. See manual for configuration:
