The test results are based on a model in which the constant-bandwidth safety and security video traffic remained unaffected during select storage failure scenarios, such as disk rebuild, node failures, and failing network paths.
We performed all tests with disk drive failures, node failures, storage process failures, or NIC failures to ensure a worst-case scenario for all sizing parameters.
We used 10 GbE interfaces with no more than two SMB connections per interface. A 10 GbE interface can accommodate up to four Recorder connections at the maximum XProtect-supported values.
We performed all tests with node or drive failures in place in the cluster (for example, with Isilon FlexProtect running) to ensure a worst-case scenario for all sizing parameters.
We performed all tests with a per-camera bandwidth of 4 Mb/s.
The following table provides bandwidth-sizing guidelines based on our test results.
Isilon cluster | OneFS version | Recorders per node | Bandwidth (MB/s) | Drive size | Tested cluster RAW | |
Per VM | Per node | |||||
A2000 | 8.1.2 | 1 | 30 | 30 | 10 TB | 1.4 PB |
