Dell EMC Series, Server Sizing Manual

Page: 26 / 26

Summary
We performed comprehensive testing with ISS SecurOS against many EMC VNX
arrays and Dell EMC Isilon clusters.
The ISS SecurOS architecture and product suite allows extreme scaling, from a few
cameras to up to tens of thousands of cameras, by using Dell EMC storage.
Dell EMC Isilon scale-out storage
Dell EMC Isilon scale-out storage is ideal for midtier and enterprise customers. An
Isilon cluster is based on independent nodes working seamlessly together to present a
single file system to all users.
Licensed SmartQuotas options can be configured so that each Video Server view of
the storage is based on the assigned quota and not the entire file system. We
recommend using SmartQuotas with ISS SecurOS as a best practice.
EMC VNX arrays
The use of storage pools to create LUNs within the EMC VNX arrays greatly simplifies
the configuration and increases the performance when compared to traditional block-
level storage. Either iSCSI or FC can be implemented. FC performs better than iSCSI.
EMC VNX-VSS arrays
The VNX Video Surveillance Storage (VSS) is a storage solution that is purpose built
to meet the unique demands of the video surveillance environment.
We found that this high availability, low-cost array performs comparably to other
arrays in the VNX family.
