My current hardware setup:
SuperMicro SC216
SuperMicro 847
19x 1.6TB SATA Intel 3500
20x 10TB SATA HGST
Current setup:
Synology 12 bay NAS
6x 10TB SATA HGST BRTFS Raid6
18TB of use
My plan is to move all current storage to a RAIDzN setup on the Intel drives. I will also add numerous VMs to the JBOF. I expect to stay within 22TB of space on the JBOF. My expectation is consuming around 50-80TB on the HGST JBOD.
Now the confusion has started. I have read so many articles and posts about 'best practices' that I feel I have entered analysis paralysis.
1. How do you begin to determine drive setups based on drive profiles? How do account for drives when you are looking at 2/4/8/10/14 and potentially larger drives? At what point in drive size do you say we need to move to RAIDz3 or run RAID60?
2. What is a safe setup for platters and in what quantity? e.g. Is an 8x drive RAIDz2 the standard or does that change based on drive size, cache, and what if a drive is SMR or not SMR... how do you begin to factor all of that?
3. Does the triad of performance, capacity and integrity change when you move to flash storage? Does it change again if using enterprise flash?
4. Does the use of a hot spare change with drive types? My guess would be there is not an issue leaving a hot spare flash drive but I do not think it would be a good practice to leave a platter SATA drive in a hot standby mode.
