Where the work begins
Build the decision around the business requirement.
Storage architecture influences application responsiveness, recoverability and operating cost. Atmic Systemics assesses file, block and workload requirements before recommending a design, helping teams make informed choices about direct-attached storage, network-attached storage (NAS), storage area networks (SAN) and other appropriate platforms. Capacity is considered alongside latency, throughput, resilience, security, management and future expansion.
Problems we help address
Clarity before configuration.
Capacity growth is visible, but the applications or data sets driving it are not
Slow file access or application response without evidence of the actual bottleneck
Shared storage permissions have become broad, inconsistent or difficult to review
Existing arrays are approaching support, performance or expansion limits
Storage snapshots, replication and backup are being treated as interchangeable protections
Scope and capabilities
What a well-scoped engagement can include.
Final scope depends on the environment, priorities, product entitlements and agreed responsibilities.
NAS and SAN planning
Evaluate file-level NAS and block-level SAN approaches against application, protocol, network, skills and availability requirements.
Performance and tiering design
Match media, caching, connectivity and data placement to measured or stated workload needs, with assumptions clearly recorded.
Access and administration
Plan logical structure, role-based access, administrative separation, monitoring, alerting and capacity reporting.
Protection integration
Align storage snapshots or replication with independent backup, retention and disaster-recovery requirements rather than assuming one mechanism covers every risk.
Potential business benefits
Designed for usefulness after handover.
Capacity and performance decisions based on workload evidence
Clearer separation of production storage, snapshots, replication and backup
Access structures that are easier to administer and review
Documented expansion and lifecycle options
A migration plan designed to limit avoidable disruption
Practical use cases
Consolidate departmental file storage
Create a governed shared platform with defined ownership, access groups, quotas where appropriate, backup and migration controls.
Support virtual server workloads
Plan datastore capacity, latency, paths and resilience around host clusters and the behaviour of priority virtual machines.
Prepare for data growth
Identify growth drivers, reclaim opportunities, archival needs and expansion choices before capacity pressure becomes an operational incident.
Assessment and implementation
A controlled route from current state to usable outcome.
Each stage establishes evidence for the next decision. The sequence is adjusted to suit risk, dependencies and change windows.
Measure and classify
Collect inventories and available metrics, identify data owners and classify workloads by access, performance, protection and retention needs.
Design and compare
Model viable architectures, network and protocol dependencies, usable capacity, resilience overhead and scale paths.
Migrate in stages
Prepare destinations, permissions and backup coverage; schedule data movement, delta synchronisation, cutover and rollback where feasible.
Validate operations
Check access, application connectivity, performance indicators, alerts, capacity reporting and recoverability before handover.
Typical deliverables
Artifacts your team can use.
- Storage inventory and requirement profile
- Capacity, performance and growth assumptions
- Target logical and physical design
- Access-control and management outline
- Migration and validation plan
- Protection and lifecycle recommendations
Planning considerations
Dependencies to surface early.
- Advertised raw capacity differs from usable capacity after formatting, protection and operational reserves.
- Performance estimates require representative workload information; capacity alone does not predict responsiveness.
- Network design and host configuration can be as important as the storage media.
- Snapshots are useful operational restore points but may share the production system's failure domain; they do not automatically constitute independent backup.
- Replication can copy corruption or deletion, so recovery design should include separate copies and tested procedures.
Frequently asked questions
Useful questions before you begin.
What is the difference between NAS and SAN?
NAS commonly provides file-level access over network protocols, while a SAN provides block storage to hosts. The better fit depends on applications, performance, availability, networking, operations and cost—not only capacity.
Can adding faster disks solve a slow application?
Sometimes, but not always. The constraint may be compute, memory, network, application queries, queue depth or configuration. Measurement should guide the change.
Is a storage snapshot a backup?
A snapshot can support rapid rollback, but many snapshots depend on the source array and may be affected by its failure or compromise. Independent backup copies, retention and recovery tests remain important.
Can permissions be preserved during a file migration?
Often they can, provided source and destination identity models, protocols and tools are compatible. Existing permissions should still be reviewed because migration can otherwise preserve unnecessary access.
How much spare capacity should be planned?
That depends on growth, procurement lead time, performance behaviour, data-reduction assumptions and platform guidance. The design documents the chosen threshold and how it will be monitored.
