Storage virtualization
Turn host disks into a manageable storage pool
Build a scalable, verifiable and maintainable storage virtualization model around VMware vSAN, host disks, storage policy, networking, capacity, redundancy and failure domains.
01 / Resource pool
See the resource relationship before deciding how to carry workloads
Storage virtualization puts hosts, disk groups, cache, capacity and workloads into one resource model. Confirm compatibility, disk types, node distribution and growth before implementation so structural limits do not appear after the pool is built.
A resource pool is not an abstract label; it must map to hosts, disk groups, network paths and workload policies.
- 01Hosts and disk groups
Check host count, disk types, cache, capacity and node distribution.
- 02Workload placement
Set resource policy around virtual machines, databases, files and backup workloads.
- 03Growth and headroom
Include data growth, rebuilds and maintenance windows in capacity planning.

02 / Storage policy
Apply capacity, performance and redundancy by workload tier
Workloads differ in performance, availability, space-efficiency and recovery needs. Storage policy must stay consistent through design, deployment, migration and acceptance instead of being configured once at go-live.
Policy gives operations a reasoned basis for why each workload uses a specific replica, protection level and capacity boundary.
- 01Protection level
Choose replicas, erasure or other protection according to workload importance.
- 02Performance tier
Validate IOPS, latency, throughput and peak access within the policy.
- 03Space efficiency
Consider usable capacity, protection overhead, rebuild space and growth headroom together.

03 / Network and failure domains
The storage network sets the pool’s performance ceiling and failure radius
Reads, writes, synchronization and rebuilds depend on a stable storage network. Check bandwidth, latency, MTU, link redundancy, switching, isolation and rack failure domains to judge whether the pool stays within workload boundaries during faults.
Networking is not an accessory outside storage virtualization; it determines whether the pool can rebuild and continue serving workloads.
- 01Connectivity and redundancy
Confirm multipath relationships among hosts, switches, nodes and management.
- 02Traffic isolation
Separate storage, management, workload, migration and backup traffic.
- 03Failure radius
Include node, rack, switch, link and room-level failures in validation scenarios.

04 / Operations handover
Handover includes an observable baseline, not only a pool
After go-live, monitor capacity, nodes, disk groups, cache, networking, alerts and rebuilds. Handover must also explain policy, thresholds, operating order, replacement procedures and data-protection boundaries.
Translate platform state into executable checks so expansion, node maintenance and disk replacement do not depend on one person’s memory.
- 01Capacity trend
Record used, available, reserved, protection overhead and growth rate.
- 02Nodes and disks
Track health, failures, rebuilds, replacements and maintenance.
- 03Policy and handover
Hand over capacity, policy, alerts, changes, backup and recovery guidance.

Next step
Start with the current environment, priorities and recovery requirements
Share the current equipment, dependencies, site conditions, data change, operating issue or delivery window so the service boundary and practical path can be reviewed.
