I’m about to run a new a server, 10x256GB SSD Disks, i plan to use RAID5 (i know it’s bad, but that’s my only option).
I will have an adaptec 5445 raid controller with BBU.
I’m starting to test xfs on some hardware, it’s seems as it’s faster so i might opt for it.
i’m planning to create the RAID5 array with 16k chunk size, that makes me mount the xfs with sunit=32,swidth=320,nobarrier
mkfs.xfs -f -d sunit=32,swidth=320 , am i correct?
I will use innodb_flush_method = O_DIRECT and innodb_flush_log_at_trx_commit = 1, i should be fine with that?
