With the modular design of the NX 7500, you can purchase the features you need today and add what you need tomorrow. As the number of users and application bandwidth requirements increase, upgrade to 10 Gigabit (10G) Ethernet, right in your facility. The fully-programmable multi-core network processing engine makes it easy to add features that require in-line data processing, without the typical limitations of hardware ASIC-based solutions. And the powerful control processor for management is accompanied by a high-throughput cryptographic engine for extreme security.
