<div id="body0000001145115787"><ul id="evs_faq_0084__ul92766418115"><li id="evs_faq_0084__li72765419117">A system disk runs the <span id="evs_faq_0084__text156518258138">server</span> OS. It is like drive C in a PC.<p id="evs_faq_0084__p845816401249">When <span id="evs_faq_0084__text949714215496">a server</span> is created, a system disk is automatically created and attached. You cannot create a system disk separately. The maximum size of a system disk is 1,024 GiB.</p>

They are like drive D, drive E, and drive F in a PC.<p id="evs_faq_0084__p1755316356109">Data disks can be created during or after <span id="evs_faq_0084__text259185710498">the server</span> creation. If you create data disks during <span id="evs_faq_0084__text196120578497">the server</span> creation, the system will automatically attach the data disks to <span id="evs_faq_0084__text106175764916">the server</span>. If you create data disks after <span id="evs_faq_0084__text16861205525016">the server</span> creation, you need to manually attach the data disks. The maximum size of a data disk is 32,768 GiB.</p>

<p id="evs_faq_0084__p1631710530417">If one system disk already meets your business needs, you do not need to create data disks. As your business grows, you can create data disks when needed.</p>

<p id="evs_faq_0084__p1976285520102">If the disk paths in your service systems cannot be changed or are difficult to change, you are advised to create data disks according to your system planning.</p>
