Aruba
The Aruba Wireless Controllers tested represent the equivalent models to the Cisco units,
including their network-connectivity bandwidth. The 7210 and 7240 are shown below: Both
models look the same from the front but support substantially different capacities. They also
support dual redundant hot-swappable power supplies.
including their network-connectivity bandwidth. The 7210 and 7240 are shown below: Both
models look the same from the front but support substantially different capacities. They also
support dual redundant hot-swappable power supplies.
The mid-range 7210, tested against the Cisco 5520, supports up to 512 APs and up to 16,384
clients. And while the controller comes with four 10GE interfaces (SFP+), it supports up to 20
Gbps of network-connectivity bandwidth.
The Aruba 7240 is the vendor's current high-end model, which was tested against the Cisco 8540.
Like the Cisco 8540, up to 40 Gbps of network-connectivity bandwidth is supported via the unit's
four 10GE interfaces. The 7240 supports up to 2,048 APs and up to 32,768 clients. Both
controllers were tested with Aruba AP 225 access points.
