I'm just curious about performance and recommendations for L1 write-through cache. I looked through the documents and white papers and don't really see what I'm looking for. They're great for how to do it, but is it worth it?
Say I have a StarWind VSAN implemented with no L1 or L2 cache, no hardware RAID or BBWC cache, no hardware caching other than what is built into hard drives, only whatever cache the OS provides. There may be UPS, but let's ignore that.
Say I want to add L1 (RAM) cache in write-through only mode. In practice, is it even worth the bother? Does L1 cache in write-through mode, by itself without any other cache, make much difference? If so, is there any info on what improvement might be expected?
Just curious.
