Private Cloud Storage: Capacity, Performance and Data Protection
Storage is where private cloud projects quietly succeed or fail. The design must answer three questions separately: how much capacity, what performance each workload needs, and how data survives a site failure.
Key Capabilities
- Tiering - hot SSD tiers for databases and virtualization, capacity tiers for files and backups.
- Scalability - start small, add nodes or shelves without downtime.
- Snapshots and backup - application-consistent local snapshots plus off-site copies.
- Disaster recovery - asynchronous replication to a second site (e.g. Shenzhen <> Hong Kong).
- Compliance - retention policies and audit trails for regulated industries.
Typical Use
A practical starting point for a 50-server estate is 30-50 TB usable with a 10 Gbps backbone; most customers then grow 20-40% per year. We include a 5-year growth model in every storage design so the first purchase is not the last.
