Dell EMC Series, Server Sizing Manual

Dell EMC Isilon node and cluster (SMB2)

The test results are based on a model in which the constant-bandwidth surveillance
video traffic remained unaffected during a single node maintenance cycle, disk rebuild,
SP failure, or non-disruptive upgrade.

We used 10 Gigabit Ethernet (10 GbE) interfaces with no more than four SMB
connections per interface. A 1 GbE interface can accommodate up to a single Video
Server connection at the maximum ISS SecurOS-supported values.

We performed all tests with a per-camera bandwidth of 7 Mb/s, so a single Video
Server that handles 65 MB/s can support 75 such cameras. If the planned deployment
requires many more cameras per Video Server, for example 200 low-resolution
cameras, the numbers in the following table are valid with a high confidence level for
bandwidth performance for up to 2,000 cameras.

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.

The following table provides bandwidth-sizing guidelines based on our test results.
