Characteristics of Data Center Market Segments
Internet Portal Data Centers
Internet based services to consumers and businesses
Concentrated industry, with small number of high growth customers
Enterprise Servers Data Centers
Business workflow, Database, Web 2.0/SOA
Large enterprise to medium Business
HPC and Analytics Data Centers
Large 1000s node clusters for HPC (DOD, Seismic,…)
Medium 100s node clusters for Analytics (e.g. FSIs …)
Complex scientific and technical

Standard networks Ethernet & Infiniband (IB) replacing proprietary networks:
IB leading in aggregate performance
Ethernet dominates in volume
Adoption of 10 Gbps Ethernet in the HPC market will likely be fueled by:
10 Gbps NICs on the motherboard, 10 GBASE-T/10GBASE-KR
Storage convergence over Ethernet (iSCSI, FCoE)
There will always be need for special solution for high end (E.g. IB, Myrinet)
But 10 GigE will also play a role in the HPC market in the future
Challenges: Need Ethernet enhancements - IB claims better technology
Low Latency, traffic differentiation, “no-drop” fabric, multi-path, bi-sectional bandwidth
