-SeaweedFS started as an Object Store to handle small files efficiently.

+SeaweedFS can transparently integrate with the cloud. With hot data on local cluster, and warm data on the cloud with O(1) access time, SeaweedFS can achieve both fast local access time and elastic cloud storage capacity, without any client side changes.
 
 There is only 40 bytes of disk storage overhead for each file's metadata. It is so simple with O(1) disk reads that you are welcome to challenge the performance with your actual use cases.
 
 SeaweedFS started by implementing [Facebook's Haystack design paper](http://www.usenix.org/event/osdi10/tech/full_papers/Beaver.pdf). Also, SeaweedFS implements erasure coding with ideas from [f4: Facebook’s Warm BLOB Storage System](https://www.usenix.org/system/files/conference/osdi14/osdi14-paper-muralidhar.pdf)

@@ -318,6 +318,16 @@ Each individual file size is limited to the volume size.
 
 All file meta information stored on an volume server is readable from memory without disk access. Each file takes just a 16-byte map entry of <64bit key, 32bit offset, 32bit size>. Of course, each map entry has its own space cost for the map. But usually the disk space runs out before the memory does.
 
+### Tiered Storage to the cloud ###
+
+The local volume servers are much faster, while cloud storages have elastic capacity and are actually more cost-efficient if not accessed often (usually free to upload, but relatively costly to access). With the append-only structure and O(1) access time, SeaweedFS can take advantage of both local and cloud storage by offloading the warm data to the cloud.
+
+Usually hot data are fresh and warm data are old. SeaweedFS puts the newly created volumes on local servers, and optionally upload the older volumes on the cloud. If the older data are accessed less often, this literally gives you unlimited capacity with limited local servers, and still fast for new data. 
+
+With the O(1) access time, the network latency cost is kept at minimum. 
+
+If the hot~warm data is split as 20~80, with 20 servers, you can achieve storage capacity of 100 servers. That's a cost saving of 80%! Or you can repurpose the 80 servers to store new data also, and get 5X storage throughput.

+## SEAWEEDFS - helm chart (2.x)
+
+### info:
+* master/filer/volume are stateful sets with anti-affinity on the hostname,
+so your deployment will be spread/HA.
+* chart is using memsql(mysql) as the filer backend to enable HA (multiple filer instances)
+and backup/HA memsql can provide.
+* mysql user/password are created in a k8s secret (secret-seaweedfs-db.yaml) and injected to the filer
+with ENV.
+* cert config exists and can be enabled, but not been tested.
+
+### current instances config (AIO):
+1 instance for each type (master/filer/volume/s3)
+
+instances need node labels:
+* sw-volume: true  (for volume instance, specific tag)
+* sw-backend: true (for all others, as they less resource demanding)
+
+you can update the replicas count for each node type in values.yaml,
+need to add more nodes with the corresponding label.
+
+most of the configuration are available through values.yaml
+
