# Class: ServerStorage

> A container whose contents are only accessible on the server. Objects
> descending from ServerStorage will not replicate to the client and will not be
> accessible from [LocalScripts](/docs/reference/engine/classes/LocalScript.md).

## Description

A container whose contents are only accessible on the server. Objects
descending from ServerStorage will not replicate to the client and will not be
accessible from [LocalScripts](/docs/reference/engine/classes/LocalScript.md).

As ServerStorage is a service it can only be accessed using the
[DataModel.GetService](/docs/reference/engine/classes/DataModel.md) method.

By storing large objects such as maps in ServerStorage until they are needed,
network traffic will not be used up transmitting these objects to the client
when they join the game.

[Scripts](/docs/reference/engine/classes/Script.md) will not run when they are parented to ServerStorage,
although [ModuleScripts](/docs/reference/engine/classes/ModuleScript.md) contained within can be accessed
and ran. It is recommended developers use [ServerScriptService](/docs/reference/engine/classes/ServerScriptService.md) to hold
[Scripts](/docs/reference/engine/classes/Script.md) they wish the server to execute.

Note that as the contents of ServerStorage can only be accessed by the server,
its contents will need to be parented elsewhere (such as [Workspace](/docs/reference/engine/classes/Workspace.md))
before clients can access them. Developers who require a container that is
accessible by both the server and client are advised to use
[ReplicatedStorage](/docs/reference/engine/classes/ReplicatedStorage.md) instead.

## Code Samples

**ServerStorage Map Rotation**

This is a very simple example of how a multiple map system can be made using
ServerStorage.

It creates three dummy models (to take the place of maps), that are parented
to ServerStorage. Then, it will load a random map (different to the previous
map) and wait a specified duration on a loop.

Developers wishing to integrate something similar into their games should
consider measures to ensure players respawn correctly, or go to a lobby during
intermission periods.

```lua
local ServerStorage = game:GetService("ServerStorage")

local ROUND_TIME = 5

local map1 = Instance.new("Model")
map1.Name = "Map1"
map1.Parent = ServerStorage

local map2 = Instance.new("Model")
map2.Name = "Map2"
map2.Parent = ServerStorage

local map3 = Instance.new("Model")
map3.Name = "Map3"
map3.Parent = ServerStorage

local maps = { map1, map2, map3 }
local RNG = Random.new()
local currentMap = nil
local lastPick = nil

while true do
	print("New map!")

	-- remove current map
	if currentMap then
		currentMap:Destroy()
	end

	-- pick a map
	local randomPick = nil
	if #maps > 1 then
		repeat
			randomPick = RNG:NextInteger(1, #maps)
		until randomPick ~= lastPick
		lastPick = randomPick
	end

	-- fetch new map
	local map = maps[randomPick]
	currentMap = map:Clone()
	currentMap.Parent = workspace

	task.wait(ROUND_TIME)
end
```
