 - [Implementation Principles](#implementation-principles)
 
-## Server-side components
-
-- **OSD** (Object Storage Daemon) is a process that directly works with the disk, stores data
-  and serves read/write requests. One OSD serves one disk (or one partition). OSDs talk to etcd
-  and to each other — they receive cluster state from etcd, and send read/write requests for
-  secondary copies of data to other OSDs.
-- **etcd** — clustered key/value database, used as a reliable storage for configuration
-  and high-level cluster state. Etcd is the component that prevents splitbrain in the cluster.
-  Data blocks are not stored in etcd, etcd doesn't participate in data write or read path.
-- **Монитор** — a separate node.js based daemon which monitors the cluster, calculates
-  required configuration changes and saves them to etcd, thus commanding OSDs to apply these
-  changes. Monitor also aggregates cluster statistics. OSD don't talk to monitor, monitor
-  only sends and receives data from etcd.
-
 ## Basic concepts
 
-- **Pool** is a container for data that has equal redundancy scheme and disk placement rules.
-- **PG (Placement Group)** is a "shard" of the cluster, subdivision unit that has its own
-  set of OSDs for data storage.
-- **Failure Domain** is a group of OSDs, from the simultaneous failure of which you are
-  protected by Vitastor. Default failure domain is "host" (server), but you choose a
-  larger (for example, a rack of servers) or smaller (a single drive) failure domain
-  for every pool.
-- **Placement Tree** (similar to Ceph CRUSH Tree) groups OSDs in a hierarchy to later
-  split them into Failure Domains.
-
-## Client-side components
-
-- **Client library** encapsulates client I/O logic. Client library connects to etcd and to all OSDs,
-  receives cluster state from etcd, sends read and write requests directly to all OSDs. Due
-  to the symmetric distributed architecture, all data blocks (each 128 KB by default) are placed
-  to different OSDs, but clients always know where each data block is stored and connect directly
-  to the right OSD.
-
-All other client-side components are based on the client library:
-
-- **[vitastor-cli](../usage/cli.en.md)** — command-line utility for cluster management.
-  Allows to view cluster state, manage pools and images, i.e. create, modify and remove
-  virtual disks, their snapshots and clones.
-- **[QEMU driver](../usage/qemu.en.md)** — pluggable QEMU module allowing QEMU/KVM virtual
-  machines work with virtual Vitastor disks directly from userspace through the client library,
-  without the need to attach disks as kernel block devices. However, if you want to attach
-  disks, you can also do that with the same driver and [VDUSE](../usage/qemu.en.md#vduse).
-- **[vitastor-nbd](../usage/nbd.en.md)** — utility that allows to attach Vitastor disks as
-  kernel block devices using NBD (Network Block Device), which works more like "BUSE"
-  (Block Device In Userspace). Vitastor doesn't have Linux kernel modules for the same task
-  (at least by now). NBD is an older, non-recommended way to attach disks — you should use
-  VDUSE whenever you can.
-- **[CSI driver](../installation/kubernetes.en.md)** — driver for attaching Vitastor images
-  as Kubernetes persistent volumes. Works through VDUSE (when available) or NBD — images are
-  attached as kernel block devices and mounted into containers.
-- **Drivers for Proxmox, OpenStack and so on** — pluggable modules for corresponding systems,
-  allowing to use Vitastor as storage in them.
-- **[vitastor-nfs](../usage/nfs.en.md)** — NFS 3.0 server allowing export of two file system variants:
-  the first is a simplified pseudo-FS for file-based access to Vitastor block images (for non-QEMU
-  hypervisors with NFS support), the second is **VitastorFS**, full-featured clustered POSIX FS.
-  Both variants support parallel access from multiple vitastor-nfs servers. In fact, you are
-  not required to setup separate NFS servers at all and use vitastor-nfs mount command on every
-  client node — it starts the NFS server and mounts the FS locally.
-- **[fio driver](../usage/fio.en.md)** — pluggable module for fio disk benchmarking tool for
-  running performance tests on your Vitastor cluster.
-- **vitastor-kv** — client for a key-value DB working over shared block volumes (usual
-  vitastor images). VitastorFS metadata is stored in vitastor-kv.
-
-## Additional utilities
-
-- **vitastor-disk** — a Vitastor OSD disk management tool. You can create, remove,
-  resize and move OSD partitions with it.
-
-## Overall read/write process
-
-- Vitastor stores virtual disks, also named "images" or "inodes".
-- Each image is stored in some pool. Pool specifies storage parameters such as redundancy
-  scheme (replication or EC — erasure codes, i.e. error correction codes), failure domain
-  and restrictions on OSD selection for image data placement. See [Pool configuration](../config/pool.en.md) for details.
-- Each image is split into objects/blocks of fixed size, equal to [block_size](../config/layout-cluster.en.md#block_size)
-  (128 KB by default), multiplied by data part count for EC or 1 for replicas. That is,
-  if a pool uses EC 4+2 coding scheme (4 data parts + 2 parity parts), then, with the
-  default block_size, images are split into 512 KB objects.
-- Client read/write requests are split into parts at object boundaries.
-- Each object is mapped to a PG number it belongs to, by simply taking a remainder of
-  division of its offset by PG count of the image's pool.
-- Client reads primary OSD for all PGs from etcd. Primary OSD for each PG is assigned
-  by the monitor during cluster operation, along with the full PG OSD set.
-- If not already connected, client connects to primary OSDs of all PGs involved in a
-  read/write request and sends parts of the request to them.
-- If a primary OSD is unavailable, client retries connection attempts indefinitely
-  either until it becomes available or until the monitor assigns another OSD as primary
-  for that PG.
-- Client also retries requests if the primary OSD replies with error code EPIPE, meaning
-  that the PG is inactive at this OSD at the moment - for example, when the primary OSD
-  is switched, or if the primary OSD itself loses connection to replicas during request
-  handling.
-- Primary OSD determines where the parts of the object are stored. By default, all objects
-  are assumed to be stored at the target OSD set of a PG, but some of them may be present
-  at a different OSD set if they are degraded or moved, or if the data rebalancing process
-  is active. OSDs doesn't do any network requests, if calculates locations of all objects
-  during PG activation and stores it in memory.
-- Primary OSD handles the request locally when it can - for example, when it's a read
-  from a replicated pool or when it's a read from a EC pool involving only one data part
-  stored on the OSD's local disk.
-- When a request requires reads or writes to additional OSDs, primary OSD uses already
-  established connections to secondary OSDs of the PG to execute these requests. This happens
-  in parallel to local disk operations. All such connections are guaranteed to be already
-  established when the PG is active, and if any of them is dropped, PG is restarted and
-  all current read/write operations to it fail with EPIPE error and are retried by clients.
-- After completing all secondary read/write requests, primary OSD sends the response to
-  the client.
-
-### Nuances of request handling
-
-- If a pool uses erasure codes and some of the OSDs are unavailable, primary OSDs recover
-  data from the remaining parts during read.
-- Each object has a version number. During write, primary OSD first determines the current
-  version of the object. As primary OSD usually stores the object or its part itself, most
-  of the time version is read from the memory of the OSD itself. However, if primary OSD
-  doesn't contain parts of the object, it requests the version number from a secondary OSD
-  which has that part. Such request still doesn't involve reading from the disk though,
-  because object metadata, including version number, is always stored in OSD memory.
-- If a pool uses erasure codes, partial writes of an object require reading other parts of
-  it from secondary OSDs or from the local disk of the primary OSD itself. This is called
-  "read-modify-write" process.
-- If a pool uses erasure codes, two-phase write process is used to get rid of the Write Hole
-  problem: first a new version of object parts is written to all secondary OSDs without
-  removing the previous version, and then, after receiving successful write confirmations
-  from all OSDs, new version is committed and the old one is allowed to be removed.
-- In a pool doesn't use immediate_commit mode, then write requests sent by clients aren't
-  treated as committed to physical media instantly. Clients have to send separate type of
-  requests (SYNC) to commit changes, and before it isn't sent, new versions of data are
-  allowed to be lost if some OSDs die. Thus, when immediate_commit is disabled, clients
-  store copies of all write requests in memory and repeat them from there when the
-  connection to primary OSD is lost. This in-memory copy is removed after a successful
-  SYNC, and to prevent excessive memory usage, clients also do an automatic SYNC
-  every [client_dirty_limit](../config/network.en.md#client_dirty_limit) written bytes.
