Networking & Infrastructure · Servers & Storage
Recording storage is where retention requirements are won or lost. FISSS sizes, supplies and configures servers, NVRs, NAS and SAN storage that keep every camera recording for the period you need.
We calculate capacity from camera counts, bitrates and retention, then design RAID groups, hot spares and throughput so arrays keep writing during a disk rebuild. Servers are specified with redundant power and network, drives are surveillance or enterprise class, and health monitoring warns before a failure becomes data loss. Our storage calculator shows the method.
| Storage types | NVR, NAS, SAN and direct-attached SAS storage |
|---|---|
| Drives | Surveillance and enterprise-class hard drives |
| Protection | RAID 5, 6 or 10 with hot spares |
| Servers | Recording, VMS and application servers with redundant PSUs |
Storage sized against the applicable MOI-SSD retention requirement and manufacturer RAID guidance.
When a disk fails, the array must rebuild while still recording every stream; we size for that worst case.
Surveillance and enterprise drives are rated for continuous writing, unlike desktop drives.
Spare bays and expansion shelves let you add cameras without replacing storage.
RAID 6 is common for large surveillance arrays because it survives two disk failures. The right choice depends on capacity, performance and budget.
Often, yes — with additional drives or expansion units — depending on the recorder model and licence.
