Why Enterprises Are Modernising Storage

Legacy storage arrays are the silent bottleneck in your IT infrastructure. Aging SAN controllers hit IOPS ceilings during peak loads. NAS filers run out of capacity faster than procurement cycles can approve expansions. Tape backups take 8-12 hours to restore a single VM.

End-of-support hardware exposes you to risk — no firmware patches, no vendor assistance during failures, and no compatibility guarantees with newer hypervisors and operating systems.

Modern NVMe arrays deliver 10x the IOPS at lower latency. Inline deduplication and compression give you 3-5x effective capacity. Object storage scales to petabytes for unstructured data at a fraction of the cost of traditional SAN/NAS.

Storage Assessment & Capacity Planning

Performance Baseline

30-day collection of IOPS (read/write ratio), throughput (MB/s), latency (ms), and queue depth. Identify peak periods, hot LUNs, and workload patterns that drive sizing decisions.

Capacity Analysis

Current utilisation, growth rate, deduplication and compression potential, and tiering recommendations. We project 18-24 months of growth to right-size the target array.

Architecture Design

Target topology — active-active HA, replication topology, DR site design, network zoning (FC/iSCSI/NFS), and integration with existing hypervisor and backup infrastructure.

Data Migration Tools & Methods

Array-Based Migration

HPE Peer Motion, Dell Data Mobility, or SAN-level volume mirroring. Data moves array-to-array without host involvement. Fastest for SAN block migrations.

Host-Based Migration

LVM mirroring, Windows disk management, or VMware Storage vMotion. Data moves through the host. Works across any array vendor — no vendor lock-in.

File-Level Migration

Robocopy (Windows) or rsync (Linux) for NAS file migrations. Incremental sync minimises final cutover window. Preserves ACLs, timestamps, and metadata.

Object Migration

MinIO mc mirror, rclone, or AWS DataSync for object-level data movement. Supports tape-to-S3, NAS-to-S3, and cloud-to-cloud migrations with checksum verification.

Backup Modernisation

Legacy Backup Problems

  • Tape backup windows exceed 12 hours
  • Tape restore takes hours for a single VM
  • Tape media failures discovered during restore
  • No off-site copy (tape in the same building)
  • No ransomware-resistant immutable backups
  • Complex tape rotation and manual handling

Modern Backup Architecture

  • Disk-to-disk-to-cloud (D2D2C) architecture
  • Incremental-forever with instant VM recovery
  • Restore single VM in minutes (not hours)
  • Immutable backups resistant to ransomware
  • Cloud copy for off-site DR (AWS S3/Azure Blob)
  • Automated verification and reporting

Our Storage Migration Process

1

Discovery & Assessment

Inventory current storage — arrays, LUNs, shares, capacity, performance. Collect 30-day metrics. Document dependencies.

2

Target Sizing & Design

Right-size target array. Design HA topology, network zoning (FC/iSCSI), replication, and backup integration.

3

Hardware Deployment

Rack, cable, and configure the new storage array. FC zoning or iSCSI networking. Host multipath setup. Initial configuration and testing.

4

Data Replication

Initiate data copy from source to target. Array-based, host-based, or file-level replication depending on the environment.

5

Validation & Testing

Checksum verification, performance benchmarks on target, application smoke tests, and backup validation on new array.

6

Cutover

Final incremental sync, switch host paths to new array, verify applications, confirm backup jobs. Typically 15-30 minutes per host.

7

Legacy Decommission

Remove old LUNs, clean FC zones, reclaim rack space. Secure data wipe on decommissioned arrays per NIST 800-88 guidelines.

8

Hypercare & Handover

30-day post-migration monitoring, performance tuning, alert configuration, and knowledge transfer to your storage team.

Frequently Asked Questions

Common triggers include: storage hardware reaching end-of-life or end-of-support, recurring performance issues (high latency, IOPS bottlenecks), capacity running above 80% utilisation with no room to expand, backup windows exceeding maintenance windows, vendor lock-in preventing flexibility, and compliance requirements for encryption at rest or data tiering that legacy arrays cannot support.

For most SAN migrations, we use host-based or array-based replication to synchronise data to the new array while the source remains online. The actual cutover (switching host paths to the new array) requires a brief maintenance window — typically 15-30 minutes per host. NAS migrations can use robocopy or rsync with incremental sync to minimise the final cutover window. We schedule cutovers during off-hours for zero business impact.

Both are modern NVMe-based storage platforms. HPE Alletra offers cloud-native management through HPE GreenLake with consumption-based pricing and AI-driven predictive analytics via InfoSight. Dell PowerStore provides a unified block and file platform with inline deduplication and compression, AppsON capability (run VMware directly on the array), and native replication. We recommend based on your existing ecosystem, workload profile, and licensing model preference.

Yes. We migrate tape-based archives to S3-compatible object storage (MinIO on-prem or AWS S3/Azure Blob). Object storage eliminates tape handling, reduces retrieval time from hours to seconds, and scales without hardware limits. We handle tape cataloguing, data extraction, metadata preservation, and validation. For regulatory archives requiring immutable storage, we configure object lock and WORM policies.

Tool selection depends on the migration path. For SAN block migrations: vendor-specific tools (HPE Peer Motion, Dell PowerStore Data Mobility), host-based LVM mirroring, or VMware Storage vMotion. For NAS file migrations: robocopy (Windows), rsync (Linux), or vendor tools like HPE Data Migrator. For object storage: MinIO mc mirror, rclone, or AWS DataSync. We always validate with checksums post-migration.

We migrate from legacy tape-based backup to modern disk-to-disk-to-cloud architectures using solutions like Veeam Backup & Replication. This includes: backup target migration (tape library to disk repository), backup job reconfiguration for new storage arrays, backup copy jobs to cloud (AWS S3, Azure Blob) for off-site DR, and tape elimination for organisations ready to decommission physical media.

We use Storage vMotion for live migration of VM datastores from legacy to new storage arrays. VMs remain running throughout the migration with zero downtime. For large-scale migrations with hundreds of VMs, we use PowerCLI automation scripts to batch-migrate VMs during off-hours. VAAI (vStorage APIs for Array Integration) offloads data copying to the array for faster migration.

We collect 30 days of performance data from your existing storage — IOPS (read/write mix), throughput (MB/s), latency (ms), capacity utilisation, and growth trends. We then right-size the new array accounting for deduplication and compression ratios (typically 3:1 to 5:1 on modern arrays), future growth projection (typically 18-24 months), performance headroom (20-30% above current peak), and HA requirements (active-active or active-passive).
