Can I Attach Multiple Vultr Block Storage Volumes to One Vultr Compute Instance?

Updated on 15 September, 2025

Yes, Vultr allows attaching up to 16 Block Storage volumes to a single Compute instance, with each volume appearing as an independent disk device in the operating system.

Yes. A single Vultr Compute instance can be attached to up to 16 Vultr Block Storage volumes simultaneously. Each attached volume is recognized by the operating system as an independent virtual disk device, allowing you to format, mount, and manage them individually.

When you attach multiple volumes, consider:

  • Device Mapping: Each volume is assigned a unique device path (for example, /dev/vdb, /dev/vdc, …).
  • Filesystem and Mount Points: You must format and mount each volume individually, unless you aggregate them using RAID.
  • Performance: Volumes are independent. Aggregate throughput depends on how your workload distributes I/O across the attached devices.
