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.

  1. 01
    Hosts and disk groups

    Check host count, disk types, cache, capacity and node distribution.

  2. 02
    Workload placement

    Set resource policy around virtual machines, databases, files and backup workloads.

  3. 03
    Growth 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.

  1. 01
    Protection level

    Choose replicas, erasure or other protection according to workload importance.

  2. 02
    Performance tier

    Validate IOPS, latency, throughput and peak access within the policy.

  3. 03
    Space 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.

  1. 01
    Connectivity and redundancy

    Confirm multipath relationships among hosts, switches, nodes and management.

  2. 02
    Traffic isolation

    Separate storage, management, workload, migration and backup traffic.

  3. 03
    Failure 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.

  1. 01
    Capacity trend

    Record used, available, reserved, protection overhead and growth rate.

  2. 02
    Nodes and disks

    Track health, failures, rebuilds, replacements and maintenance.

  3. 03
    Policy and handover

    Hand over capacity, policy, alerts, changes, backup and recovery guidance.
