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. We recommend...

		scheme = strings.ToLower(proto)
	} else if proto = r.Header.Get(xForwardedScheme); proto != "" {
		scheme = strings.ToLower(proto)
	} else if proto := r.Header.Get(forwarded); proto != "" {
		// match should contain at least two elements if the protocol was
		// specified in the Forwarded header. The first element will always be
		// the 'for=', which we ignore, subsequently we proceed to look for
		// 'proto=' which should precede right after `for=` if not

	// assert the content body for the expected object data.
	c.Assert(true, bytes.Equal(responseBody, []byte("hello one")))

	// data for new object to be uploaded.
	buffer2 := bytes.NewReader([]byte("hello two"))
	objectName = "testObject2"
	request, err = newTestSignedRequest(http.MethodPut, getPutObjectURL(s.endPoint, bucketName, objectName),
		int64(buffer2.Len()), buffer2, s.accessKey, s.secretKey, s.signer)
	c.Assert(err, nil)

## Overview

MinIO supports two storage classes, Reduced Redundancy class and Standard class. These classes can be defined using environment variables

		if err != nil {
			return nil, err
		}
		// If there is a multipart upload with the same bucket/object name,
		// create the new multipart in the same pool, this will avoid
		// creating two multiparts uploads in two different pools
		if len(result.Uploads) != 0 {
			return z.serverPools[idx].NewMultipartUpload(ctx, bucket, object, opts)
		}
	}

	// any parallel writes on the object will block for this poolIdx

		t.Fatalf("%s: <ERROR> %s", instanceType, err)
	}
	if len(buckets) != 1 {
		t.Errorf("%s: Expected number of bucket to be `%d`, but instead found `%d`", instanceType, 1, len(buckets))
	}

	// add two and test exists.
	err = obj.MakeBucket(context.Background(), "bucket2", MakeBucketOptions{})
	if err != nil {
		t.Fatalf("%s: <ERROR> %s", instanceType, err)
	}

	buf.WriteString("Records")

	fmt.Println(buf.Bytes())

// Header specification
// --------------------
// Continuation messages contain two headers, as follows:

// Continuation messages have no payload.
