Bandwidth sizing guidelines
All solution tests were performed in a lab environment. The storage system, cameras,
and VLANs in the lab environment were dedicated to these tests.
Connections to the storage system under test conditions were restricted to SecurOS
Video Server, monitoring, and web management stations. Expect some variance
between the lab results and a production environment.
EMC VNX
We conducted validation tests to determine how ISS works with VNX storage arrays.
The test results shown in the following table are based on a conservative model to
ensure that the constant-bandwidth video traffic is unaffected during a single storage
pool (SP) maintenance cycle, disk rebuild, or similar performance-intensive events.
The VNX 5300 and VNX-VSS100 can exceed 500 MB/s in an environment without
induced errors.

Note
All disks are NL-SAS, 4 TB 7200 RPM drives unless otherwise stated.
The following table lists the firmware builds used in these tests. Expect equal or better
results if you use more recent firmware or newer models of VNX storage.
