Facing heavy competition, telecommunication carriers try to seek the method of low costs and high flexibility, well use the expansible standard platform and transfer to the newgeneration network environment, to integrate services.
The traditional Mini Computer networking is not flexible.
In the beginning, users of new services are few. The small capacity solution is required to reduce the one-time investment. Afterwards when the traffic increases, it is convenient for the capacity expansion.
Telecommunication carriers need standardized, modular and flexible networking telecommunication equipment as well as more flexible solutions.

Advanced telecom computing architecture (ATCA) is developed from the next generation mainstream industrial computing technology -- CompactPCI standard, which is widely applied in telecom, astronautics, industrial control, medical appliance, intelligent traffic, and military facility. The ATCA provides a modularized, compatible, scalable, and excellent price-performance-ratio hardware architecture for the next generation integrated telecom and data network application.
Basic features:
Dual -48VDC redundancy power supply
High-speed differential signal connector
8U x 280mm blade size；
1.2 inches spaces between every two blades, convenient for heat dissipation design
High-speed hot swap daughter card
Standard Intelligent Platform Management Bus(IPMB), every component in the system is manageable
Open Software Architecture
A pure ATCA system defined in PICMG 3.X only includes Frame, Computing Board and Switch Board. So each vendor of ATCA has to provide a complete solution which includes all of the other management modules as mentioned in above diagram.
HUAWEI ATAE is one of such commercial system, which is based on ATCA and provides a powerful environment for telecom system.
ATAE solution is consisted of two parts: hardware and software.
The hardware platform contains:
Shelf: Frame + Computing Board + Switch Board + Management Board
Network Devices
Storage Devices
Rack (Cabinet)
The software part is USM, and USM is consisted of 3 parts: USMAS, DMS and IPA, that means:
USM = USMAS + DMS + IPA
Furthermore, the whole platform can be managed by HUAWEI NMS: I2000.
According to the power entry type:
AC Rack: If the entry power is DC, then it’s called DC rack.
DC Rack: If the entry power is AC, then it’s called AC rack.
According to the devices installed:
Basic Rack
Shelf, USM、storage, minicomputer, LAN switch.
The necessary configuration of ATAE，small office can configure one basic rack only.
Extended Rack
Storage Rack
2 shelves.
Hard disk array.
Network Rack
Network equipments, such as LAN switch 、firewall、load balancer.
This is just an example, actual deployment may be different.
Below is the introduction of these devices:
Shelf: ATAE solution core hardware.
N240: Minicomputer.
CX300/SUN3510/S3100: Storage.
5624: LAN switch.
The difference between AC rack and DC rack is:
Because the Shelf can accept -48V DC power only, so the AC rack need a AC/DC power converter.
According to the real configuration on-site, the ATAE solution is 80% the consumption of the servers. As the consumption is reduced, the air-condition consumption will be reduced too. The proportion between system consumption and air-condition is 1:3(that means 1W system consumption need 3W heat dissipation consumption). A full configured ATAE can save 57600W air-condition consumption every hour compared with the servers.
Advantage hot simulation analysis
Guarantee that the system can run normally under the extreme situation
Local Enforced Cooling Design
Pump air from bottom to top and from front to back; Guarantee the system dissipating heat equably
Intelligent Cooling Technology
The cooling system can adjust the fan speed according to the internal temperature
Fans Redundancy Protect Technology
The core components of the cooling system -- Fan tray use the double design. Support the Redundancy Protect.
In this Architecture, we can see these devices:
PC Servers
LAN Switches
FC Switches
Storage
KVM and KVM Switches
Power Cords
Ethernet Cables
Fiber Cables
Too Many kinds of devices, and too many cables, it’s very hard to maintenance.
In this Architecture, we can see these devices:
Server Boards
Switch Boards
Storage
In ATAE architecture, we just need some boards, they are server boards and switch boards. The size is much more smaller.
This is the physical device, and you can see all the server boards and switch boards are in the same frame, and they are connected internally through the backplane which is also responsible for power supply, so you just need connect it to Internet and storage.
Very simple architecture, highly integrated, easy to understand and maintenance.
iKVM
iButton
Simultaneously monitoring four servers
Remote power-on/off and start/stop (i-Button)
iMedia
Remotely monitoring software and hardware information including BIOS and OS boot
Remote access by protocols
Linux/Unix OS
Telnet and SSH protocols
Window OS
RDP
High Density and Scalability
High Reliability
Compliant with NEBS L3 / ETSI Full redundancy supported, dual power supply Hot plug replacement of all blades Electronic anti-misplug Protection Over-loading Protection of Power Supply
High Availability
1 Rack,2 shelf, 24 Blades Cascade shelf supported Calculating: dual and quad-core processors, from Intel, AMD Storage: internal, attached (SCSI, FC, SAS), Up to many TBs Networking: 112 GE per shelf
Configuration auto-recovery Software deployment and upgrade by batch Consolidates management for the entire shelf iTools for remote maintenance: iButton, iMedia, iKVM USB based Local KVM
Power-saving
The intelligent variable frequency converting for processor The intelligent activator for fan The high conversion efficiency of power supply is up to 90% High performance fan group
