A Battle Rages Blade Servers ATCA Telecom Applications Market 4

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 c. PCI • ETSI and NEBS-ready • Many redundancy features • Highly Scalable • Centralized management Alliance Systems ATCA Chassis 5

ATCA Physical Form Factor • Dimensions: – Front board size 8 U x 280 mm – Rear board size 8 U x 70 mm • Connects directly to front board 6

ATCA – Benefits for Telecom • Larger physical board – More usable board space • 200 W / board – Faster / more processors • Improved mechanical design – Better heat dissipation – Interface to rear transition modules • 1 Gbps Base Interface • Choice of Fabric Interfaces – Ethernet, Fibre Channel, Star. Fabric, PCI-Express, Rapid. IO • Separate IPMI management 7 Audio. Codes TP-12610

ATCA vs. CPCI Attribute PICMG 2. 16 (c. PCI/CPSB) PICMG 3 ATCA Size 6 U x 160 mm x. 8” ; 57 sq in 8 U x 280 mm x 1. 2”; 140 sq in 2 x PMC 4 x PMC ; 8 x AMC 35 -50 W, central converter 5/12/3. 3 V on backplane 150 -200 W, distributed converter Dual 48 V on Backplane 38 Gb/s 2. 4 Tb/s Managment OK Advanced Clocks, update bus No Yes Regulatory conformance Vendor specific In-standrad Mezzanine Power Bandwidth 8

ATCA Interfaces • Zone 1 – Power – Dual 48 V, 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 – 8 KHz, 19. 4 MHz, GP, dual redundant • Zone 3 – Vendor-specific Rear connections – Backplane is open 9

ATCA Fabric Interface Types The Fabric is Dedicated for Bearer Data: – Packet voice (IP/ATM) – TDM voice (H 110 - like) PICMG 3. X – 3. 1 – Ethernet and Fiber Channel – 1 GBit/s ü Very common and widely supported o TDM and ATM support problematic – 3. 2 – Infini. Band, 2. 5 Gb/s – 3. 3 – Star. Fabric, 2. 5 Gb/s ü Designated for TDM, Packet and PCI transport o Questionable availability so far o Supported by Star. Gen only – 3. 4 – PCI-Express & Advanced Switching ü ü ü o 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 – Rapid. IO & Advanced Fabric Interface, 2 Gb/s The Big Question: Which 10 one will dominate?

Comparison: ATCA vs. Blade Servers 21 Feature / Capability ATCA Blade Servers Commercial Volumes No Yes Modular (AMC / Micro. TCA) Yes Limited Enterprise and Telco versions No Yes Chassis Management Yes Telecom-friendly Rear Transition Modules Yes Limited NEBS Yes Some Interoperability / Open Specification High Low

Where will they fit? Telecom Applications Billing / Management Applications Access / Edge 22 ATCA Fit Blade Server Fit Too expensive Excellent Good Excellent Poor

Other Interesting Facts: ü Intel is investing heavily in ATCA ü Sun abandon their proprietary blade server and has adopted ATCA ü HP has strong telecom history/partnerships ü HP has struck a deal with Intel to deliver ATCA ü IBM has opened up the Blade. Center specification via IEEE and Blade. org ü IBM is aggressively working with a range of ISV partners 23
