Designed for 99.999% availability, SBS is automatically replicated multiple times across a redundant and highly available cluster of storage servers to protect your data from component failure. ### Can I move my SBS between servers in the same location? Yes, you can move your SBS between your servers in the same location. ### Can I move my SBS between servers in different locations? Not currently, but it is on our roadmap. ### Is there a limit on how many SBS volumes I can connect to my Cloud Server? You can connect up to 15 volumes per Cloud Server. ### Can an SBS be attached to more than one Cloud Server at the same time? No, SBS can only be attached to one server at a time. However, SBS can be used as the backing storage for a shared file system, like NFS, that multiple servers/clients can connect to. ### Will I be able to take on-demand snapshots of my SBS and restore my volume from them? No. However, we plan to offer this feature soon. ### If I pay for backups of my Cloud Server, does that include backups of my attached SBS? No, however we do have backup solutions available through our sales team and plan to roll out on-demand options as well. ### Can I add an SBS on the Add Server page when creating a new Cloud Server? No. However, we plan to offer this feature soon. ### You mentioned that you can scale Volumes with no downtime, but I noticed the asterisks there. Can you please explain? Currently, all of our Cloud Server operating systems, except Windows Server 2016, support live scaling of Block Storage Volumes. This means that for all other Cloud Server operating systems, you can resize your Volume while it is connected to your running server. For Windows Server 2016, you will either have to reboot your Cloud Server or detach and reattach the Volume to get your Cloud Server to recognize the additional space after resizing a volume. This is a limitation of Windows Server 2016. ### Is the storage that backs SBS hard disk (HDD) or solid-state disk-based (SSD)? The storage that backs SBS is 100% NVMe SSD based. This ensures you can take advantage of the amazing speed that comes with NVMe SSDs. NVMe, if you are not familiar, stands for non-volatile memory express and is the successor to the SATA drive interface. It allows SSDs to transfer data directly over the server's PCIe bus instead of going over the much slower SATA interface. ### What are the specs of SBS? Pure NVMe based Block Storage; Volume Size: 10 GB to 16 TB; Max volumes per server: 15; Max IOPS per volume: 7,500; Max burst IOPS per volume: 10,000; Max throughput per volume: 300 MB/s; Max burst throughput per volume: 450 MB/s; All-inclusive pricing: 10 cents per GB per month. ### Is SBS encrypted? Yes, every SBS is automatically encrypted at rest using LUKS encryption and is connected to your Cloud Server over an isolated storage network to ensure a secure environment for customer data. ### What is the minimum increment when scaling the capacity of SBS? The minimum scaling increment is 10 GB. ### How does SBS compare to a SAN? A SAN is typically defined as a dedicated storage area network that provides direct access to block-level storage devices with a finite amount of capacity and performance. SBS offers block storage as well, with clear advantages over a SAN in that SBS provides easily scalable capacity, performance, and redundancy coupled with no management costs. ### How does SBS compare to a NAS? A NAS is typically defined as network-attached storage that provides a shared file system, such as NFS, that multiple servers can connect to at the same time. In contrast, SBS is a block-level device that can only be directly attached to one server at a time but provides more flexibility. For example, SBS can be used to provide additional storage capacity for a Cloud Server or can be used as the backing storage for a shared file system, like NFS, that multiple clients can connect to. ### Do you plan to offer SBS at additional locations? Yes, we plan to offer SBS at our other Cloud locations. Currently, SBS is available in our USA-EAST-1 (Orlando, FL) location. Details regarding the launch of SBS at additional locations will be released in the coming months. ## Read More About Block Storage ### [What Is Block Storage?](https://www.atlantic.net/vps-hosting/what-is-block-storage/) - [What Is Block Storage?](https://www.atlantic.net/vps-hosting/what-is-block-storage/) - [Pros and Cons of Offsite and Onsite Data Storage](https://www.atlantic.net/hipaa-compliant-hosting/pros-and-cons-of-onsite-and-offsite-data-storage/) ## Dedicated to Your Success Jason Coleman VP of Information Technology, Orlando Magic > "After evaluating a range of managed hosting options to support our data operations, we chose Atlantic.Net because of their superior infrastructure and extensive technical knowledge."
