We are building a raid-10 with LSI 9260-4i + 4 x Intel DC S3500 SDDs.
From what I understand I need to start fdisk with -H32 -S32 or Ted T'so variant with -H224 -S56 in order to align the partitions to 512k and 128k respectively.
But what about file system alignment?
Normally I understand it's advisable to specify the stride and stripe width when running mke2fs.ext4.
But is it needed for hardware raid? Or because the hardware presents itself as a single storage device it's not needed?
Raid type: Raid 10 hardware Chunk size: probably 64kb File system block size: 4k Number of SSDs: 4 DC S3500 erase block: unknown (maybe 128k)
