Related Capabilities
| ID | Title | Description |
|---|---|---|
| CCC.FileStor.CP06 | Performance Tiers | The service may be configured to select throughput and latency performance tiers or modes matched to workload requirements. |
| CCC.Core.CP04 | Transaction Rate Limits | The service can throttle, delay, or reject excess requests when transactions exceed a user-specified rate limit, and always provides industry-standard throughput up to that limit. |
| CCC.Core.CP16 | Budgeting | The service may be configured to take a user-specified action when a spending threshold is met or exceeded on a child or networked resource. |
| CCC.Core.CP19 | Child Resource Scaling | The service may be configured to scale child resources automatically or on-demand. |
Related Threats
| ID | Title | Description |
|---|---|---|
| CCC.FileStor.TH06 | Under-Provisioned Performance Tier Degrades Availability | The selected throughput or performance tier may be insufficient for concurrent client I/O against the shared file system. Read and write operations are throttled or delayed beyond application tolerance. This impacts availability of workloads that depend on timely file access. |
| CCC.Core.TH12 | Resource Constraints are Exhausted | Exceeding the resource constraints through excessive consumption, resource-intensive operations, or lowering of rate-limit thresholds can impact the availability of elements such as memory, CPU, or storage. This may disrupt availability of the service or child resources by denying the associated functionality to users. If the impacted system is not designed to expect such a failure, the effect could also cascade to other services and resources. |
Assessment Requirements
| ID | Text | Applicability |
|---|---|---|
| CCC.FileStor.CN06.AR01 | When throughput or IOPS utilization on the file system exceeds a configurable threshold, the service MUST publish a metric or alert to a monitored channel. | tlp-green, tlp-amber, tlp-red |
| CCC.FileStor.CN06.AR02 | When a performance tier is provisioned, the service MUST expose the configured throughput or IOPS limits to authorized operators. | tlp-clear, tlp-green, tlp-amber, tlp-red |
