Chelsio から新 ASIC: T4採用の Unified Wire Adaptersが発表されました:


 Chelsio T4 Is Industry's First Converged Network Adapter -
 Enabling TCP, UDP, iSCSI, iWARP, and FCoE Offload Over Single
 Unified Wire With SR-IOV, EVB/VNTag, DCB
 February 28, 2011

  "... today announced availability of its fourth generation Terminator
   4 technology in the first release of a new family of 10Gb Ethernet
   adapter cards.  The T4 cards are the industry's first Ethernet
   converged network adapters capable of simultaneously offloading all
   the major networking and storage protocols (TCP, UDP, iWARP, iSCSI,
   and FCoE) with Single Root IO Virtualization (SR-IOV)."

Targeted at Virtualized Clouds, Data Centers, Storage and HPC
  "...  Along with the extensive offload capabilities of the T4, the
   embedded switch enables further performance advantages for
   virtualized environments, switching traffic from up to 140 virtual
   and physical ports within the T4 adapter.  The T4 supports PCIe
   SR-IOV (8 Physical Functions, 128 Virtual Functions) with advanced
   QoS and traffic management functionality, enabling state-of-the-art
   virtualization design."

[san-tech][02161] Chelsio 新チップ発表

Chelsioが新しいチップ (Terminator 4 ASIC) を発表しました:

 Feature-Rich T4 ASIC Offloads TOE, FCoE, iSCSI, iWARP To Enable
 Converged Networks Over Single Unified Wire", March 22, 2010

  "Targeted at LAN-on-motherboard (LOM) design opportunities, the
   Terminator 4 (T4) is a highly integrated, highly virtualized
   10GbE controller built around a programmable protocol-processing
   engine.  T4 includes Chelsio's fourth-generation TCP offload
   (TOE) design, third generation iSCSI design, and second-generation
   iWARP (RDMA) implementation.  In addition to full TCP and iSCSI
   offload, the T4 also supports full Fibre Channel over Ethernet
   (FCoE) offload."


The Terminator 4 ASIC

"The Terminator 4 ASIC represents Chelsio's fourth-generation TCP
 offload (TOE) design, third-generation iSCSI design, and
 second-generation iWARP (RDMA) implementation."
"The T4 will begin sampling to key OEM partners in Q2, and broad
 availability is expected in Q3."

Key new features include:
   1. PCI Express Gen2 x8 host bus interface
   2. Four ports of 100M/1G/10G
   3. Integrated KX4, CX4, KX, KR, SGMII
   4. Full TCP and UDP offload
   5. Full iSCSI, FCoE offload
   6. Full iWARP RDMA offload  
   7. SR-IOV
   8. VEB/VEPA
   9. NC-SI
  10. Memory-less operation
