HP Unified Wired and Wireless
Good afternoon, Habrahabr!
It is no secret to anyone that in the modern world mobile technologies have completely turned people around about where and how to work. High-performance wireless networks have long ceased to be a luxury for companies and have become a necessity. Despite all this, often a wireless network stands apart from a wired campus network with its equipment, management, its settings and policies.
It's time to change the approach and simplify the work, deployment and administration of wireless networks! HP Unified Wired and Wireless Network , part of the HP FlexNetwork architecture , is
called upon to help .
First of all, this solution includes a new line of equipment, namely, wireless access controllers / switches.
Let's start with the HP 830 Unified Wired-WLAN Switch :
The HP 830 Unified Wired-WLAN Switch series combines a wireless access controller and a gigabit PoE + switch.
Such an implementation is convenient for organizing small and medium-sized wireless networks, as it allows you to make an access network using one device. Such a network will be scalable, since the number of access points supported by the controller can be expanded with licenses to 60 access points per controller.
As a result, we get:
• Unified management and policies for LAN and WLAN users;
• Unified management using IMC;
• Built-in portal authentication server and IEEE 802.1X;
• Switches with 8 and 24 GbE PoE + ports;
• Wi-Fi Clear Connect technology for optimizing wireless networks.

For larger solutions, the more efficient HP 850 Unified Wired-WLAN Appliance controller , which has 8 gigabit combo ports and 2 10G interfaces, is suitable .
Such a device provides support for up to 512 access points per controller with a centralized bandwidth of 10G. A distinctive feature of the controllers HP 850 and older is the support of 1 + 1 redundancy of controllers, with the time of detecting a malfunction of the main controller in milliseconds. The IEEE 802.1X hot-backup functionality, which synchronizes the state of 802.1X along with information about connected clients between controllers, allows you to save client connections when the main controller fails. Also do not forget about the possibility of redundant power supplies.
For more information, see the HP 850 Unified Wired-WLAN Appliance .
Next in the line is an even more powerful HP controller .The 870 Unified Wired-WLAN Appliance , which has 40G bandwidth and supports 1,536 access points.
The device has 12 copper and 12 SFP gigabit interfaces, as well as 4 SFP + interfaces. The controller also has redundancy of power supplies and IEEE 802.1X hot-backup technology, which allows for uninterrupted operation of all access points as the central controller of a wireless LAN for large companies and large-scale implementations.

For large solutions with HP wired network, the controller is also implemented as an HP 10500/7500 20G Unified Wired-WLAN Module service card .
As the name implies, this module is suitable for chassis switches of the HP 10500 and HP 7500 series. The bandwidth of traffic processing when deploying the centralized architecture of this module is 20G. One module provides support for up to 1024 access points. By increasing the number of such modules in the chassis, you can get 11264 access points supported by one chassis. Implemented support for the backup of such modules, as well as the functionality of 802.1X hot-backup.

A few words about the functionality of the HP Unified Wired and Wireless Network solution:
• Wi-Fi Clear Connect - technology of radio frequency optimization, automatic noise suppression and dynamic load balancing, which provides more efficient communication in high-density client environments;
• Advanced radio resource management - automatic adjustment of radiation power, channel selection, balancing clients by access points, even distribution of the time the environment is used between clients;
• Spectrum Analysis - spectral analysis that allows you to detect and avoid interference (including not from wi-fi devices);
• Band Navigation - the ability to redirect clients supporting the 5 GHz band to the 5 GHz band, which is less prone to interference;
• VLAN pooling - the ability to dynamically distribute clients across multiple VLANs within the same SSID;
• Policy based forwarding - the ability to create policies that affect the direction of traffic, ACL-based traffic classification, the choice of a centralized or distributed traffic flow direction. Similar policies can be applied to an SSID, user group, or per user;
• Quality of Service (QoS) - classification, polising and prioritization of traffic;
• Integrated Wireless Intrusion Detection System (WIDS) - built-in system for detecting wireless intrusions into the network;
• Integrated Wireless Intrusion Prevention System (WIPS) - built-in system to prevent wireless intrusions into the network;
• Wireless Intelligent Application Aware Feature (WIAA) - built-in firewall that works on SSID or user roles;
• NAT / NAT traversal - the ability to translate addresses, as well as support for access points behind NAT;
• Fast roaming - of course, fast roaming (including 3rd level);
• High reliability - the ability of the controllers to reserve each other according to various schemes (1 + 1, N + 1 and even N + N);
• Bonjour support - support for the "apple" network protocol, which makes life and networking with Apple products easier;
• And much more ... A more complete list can be found at the link (section Overview).
