Block Storage

Cloud servers on UpCloud are deployed on high-performance redundancy-enabled block storage, a standard storage technology in cloud servers, analogous to hard drives in physical computers.

All block storage is served from a storage area network where block storage devices are stored in clusters of two separate storage backends to ensure high performance and availability. Additionally, data on the storage backends are stored on multiple disks in a RAID array to further improve redundancy.

Users have a choice between MaxIOPS and HDD storage tiers with user-selectable capacity.

Each storage device can be scaled from 1 GB up to a maximum of 4 TB per volume in 1 GB increments.

Cloud servers can attach up to 16 concurrent block storage devices per server to a total of 64 TB of storage.
