Reed-Solomon code to shard objects into variable data and parity blocks. For example, in a 12 drive setup, an object can be sharded to a variable number of data and parity blocks across all the drives - ranging from six data and six parity blocks to ten data and two parity blocks.

By default, MinIO shards the objects across N/2 data and N/2 parity drives. Though, you can use [storage classes](https://github.com/minio/minio/tree/master/docs/erasure/storage-class) to use a custom configuration....

on 16 drive MinIO deployment. If you use eight data and eight parity drives, the file space usage will be approximately twice, i.e. 100 MiB
file will take 200 MiB space. But, if you use ten data and six parity drives, same 100 MiB file takes around 160 MiB. If you use 14 data and
two parity drives, 100 MiB file takes only approximately 114 MiB.

// returns it.
// This is not a critical function, and it is allowed
// to fail with a ten seconds timeout, returning nil.
func getClusterMetaInfo(ctx context.Context) []byte {
	objectAPI := newObjectLayerFn()
	if objectAPI == nil {
		return nil
	}

	// Add a ten seconds timeout because getting profiling data
	// is critical for debugging, in contrary to getting cluster info
