ATCA and a number of Blade Server platforms offer a number of advantages to developers of next-generation applications. Density, simplicity of cabling and manageability all reduce the cost of ownership. But which platform to choose for your new solution? This session will take a closer look at ATCA, it’s ‘little brother’ MicroTCA, and a number of Blade Server platforms and explore their applicability for telecommunications applications. 1 Hour

A Battle Rages Blade Servers ATCA Telecom Applications Market

ATCA – What is it? Platform for both telecom and computing applications High Availability features Specified by PCI Industrial Computers Manufacturers Group (PICMG 3.0) Successor to cPCI ETSI and NEBS-ready Many redundancy features Highly Scalable Centralized management Alliance Systems ATCA Chassis

ATCA Physical Form Factor Dimensions: Front board size 8U x 280 mm Rear board size 8U x 70 mm Connects directly to front board

ATCA – Benefits for Telecom Larger physical board More usable board space 200W / board Faster / more processors Improved mechanical design Better heat dissipation Interface to rear transition modules 1Gbps Base Interface Choice of Fabric Interfaces Ethernet, Fibre Channel, StarFabric, PCI-Express, RapidIO Separate IPMI management AudioCodes TP-12610

ATCA vs. CPCI Attribute PICMG 2.16 (cPCI/CPSB) PICMG 3 ATCA Size 6U x 160mm x .8” ; 57 sq in 8U x 280mm x 1.2”; 140 sq in Mezzanine 2 x PMC 4 x PMC ; 8x AMC Power 35-50W, central converter 5/12/3.3V on backplane 150-200W, distributed converter Dual 48V on Backplane Bandwidth 38 Gb/s 2.4 Tb/s Managment OK Advanced Clocks, update bus No Yes Regulatory conformance Vendor specific In-standrad

ATCA Interfaces Zone 1 Zone 2 Zone 3 Power – Dual 48V, distributed conversion Management – Dual redundant IPMB Keying Zone 2 Base interface – Dual star GBETH for control (CPSB like) Fabric interface – PICMG 3.X Update channel – between adjacent slots for 1+1 redundancy Clocks – 8KHz,19.4MHz,GP, dual redundant Zone 3 Vendor-specific Rear connections Backplane is open

ATCA Fabric Interface Types The Fabric is Dedicated for Bearer Data: Packet voice (IP/ATM) TDM voice (H110 - like) PICMG 3.X 3.1 – Ethernet and Fiber Channel – 1GBit/s Very common and widely supported TDM and ATM support problematic 3.2 – InfiniBand, 2.5Gb/s 3.3 – StarFabric, 2.5Gb/s Designated for TDM, Packet and PCI transport Questionable availability so far Supported by StarGen only 3.4 – PCI-Express & Advanced Switching Targeted to all types of Fabric applications PCI-express Widely supported – Driven by PC industry Sponsored by Intel, Alcatel, Siemens etc. Chipsets still NA 3.5 – RapidIO & Advanced Fabric Interface, 2Gb/s The Big Question: Which one will dominate?
