Storage Overview

DanubeData provides high-performance, reliable storage solutions for your cloud infrastructure. This guide covers storage types, features, and best practices.

Overview

Storage options include:

  • NVMe SSD Storage: Ultra-fast NVMe storage included with all instances
  • Block Storage: Additional persistent storage volumes
  • Snapshots: Point-in-time backups of volumes and instances
  • Database Storage: Managed database storage with automatic scaling
  • Backup Storage: Long-term backup storage

Storage Types

NVMe SSD Storage

Included with all VPS instances:

  • Performance: Up to 3,000+ MB/s read, 2,000+ MB/s write
  • IOPS: 100,000+ random read IOPS
  • Latency: Sub-millisecond latency
  • Reliability: Enterprise-grade NVMe SSDs
  • Included: Part of instance profile

Block Storage

Additional persistent volumes — the productized Volumes feature:

  • Capacity: 10–500 GB per volume
  • Performance: network-attached SSD storage
  • Flexibility: Attach/detach from instances
  • Snapshots: Create point-in-time backups
  • Scaling: Resize volumes without downtime

Snapshots

Backup volumes and instances:

  • Full Backups: Complete volume/instance copies
  • Incremental: Only changed data after first snapshot
  • Instant Recovery: Restore in minutes
  • Retention: Keep snapshots as long as needed

Storage Performance

NVMe Performance

Typical performance metrics:

MetricValue
Sequential Read3,000+ MB/s
Sequential Write2,000+ MB/s
Random Read IOPS100,000+
Random Write IOPS80,000+
Latency< 1ms

Block Storage Performance

Volumes are network-attached, with throughput up to ~1 Gbps. For the highest IOPS, use the local NVMe on your VPS root disk.

Best Practices

Storage Management

  1. Right-Size Volumes: Start small, scale as needed
  2. Regular Snapshots: Backup important data
  3. Monitor Usage: Track storage consumption
  4. Clean Up: Delete unused volumes and snapshots
  5. Use Block Storage: For data that needs to persist independently

Performance Optimization

  1. Use NVMe: Fastest performance for OS and applications
  2. Separate Data: Use block storage for data volumes
  3. RAID Not Needed: Storage already redundant
  4. Filesystem Tuning: Use ext4 or xfs for best performance
  5. Monitor IOPS: Ensure not hitting limits

Data Protection

  1. Regular Backups: Automate snapshot creation
  2. Test Restores: Verify backups work
  3. Multiple Copies: Export important snapshots for offsite copies
  4. Encryption: Enable encryption for sensitive data
  5. Access Control: Limit who can delete volumes
