# XSDS Administration Guide

> Deploy and operate Xloud Software-Defined Storage clusters — pool management, CRUSH maps, storage tiers, encryption, capacity planning, and maintenance.

<p style={{ fontSize: '1.25rem', fontWeight: 700, marginBottom: '0.75rem' }}>Overview</p>

As an XSDS administrator, you are responsible for deploying and operating the distributed
storage cluster that underpins block, object, and file storage for all Xloud tenants.
This guide covers cluster architecture, pool and CRUSH map management, storage tier
configuration, capacity planning, encryption, monitoring, and common operational procedures.

<Warning>
  **Administrator Access Required** — This operation requires the `admin` role. Contact your
  Xloud administrator if you do not have sufficient permissions.
</Warning>
