(While the server is stopped, only the basic disk fee to install the operating system will be incurred.) | ### Server creation limit by server type The server creation limit differs according to the country and member type (individual, corporate) selected upon signing up. If you want to change the limit, request it through [Customer support > Contact support](https://www.ncloud.com/support/question/service?parentCode=O2O_SVR&code=O2O_SVR_001_005). Note If you need more servers than the server creation limits, check the [FAQs](https://www.ncloud.com/support/faq/all/3178) and contact [Customer support](https://www.ncloud.com/support/question/service?parentCode=O2O_SVR&code=O2O_SVR_001_005) to increase the limit. ## Server image specifications For more information on server images provided by NAVER Cloud Platform, see [Various server images](https://www.ncloud.com/product/compute/server). ## Storage specifications Additional Block Storage specifications are as follows: | Item | HDD | SSD | | --- | --- | --- | | Minimum size | 10 GB | 10 GB | | Maximum size | 2 TB | 2 TB | | Maximum number of additional storages | 15 (may vary depending on the operating system) | 15 (may vary depending on the operating system) | Note - The maximum number of additional storages does not include the default storage. 1 default storage is provided when you create a server, and you can add 15 additional storages. - When it comes to SSD block storage, 4000 IOPS is provided between 10 GB to 100 GB. Afterward, it increases by 40 IOPS per 1 GB. Up to 20,000 IOPS (4 KiB I/O) is provided. ## ACG specifications Each account of NAVER Cloud Platform has a default ACG created. The ACG provided by default follows the basic rules as follows: - Block all inbound traffic. - Allow all outbound traffic (specified as rule). - Allow bidirectional network communication between servers in Default ACG (added as rule, can be deleted). Note ACGs directly created by users have no rules for outbound traffic, so all outgoing connections are blocked. ## Pricing information Server is serviced on a pay-as-you-go pricing plan.
