The Terminator Series ( Terminator 4 (T4) and Terminator 5 (T5) ) adapters are all-in-one Unified Wire Adapters and offer full iSCSI offload Adapters/cards/NIC’s capability in protocol acceleration for both file and block‐level storage (iSCSI) traffic. For file storage, the Terminator Series ( Terminator 4 (T4) and Terminator 5 (T5) ) supports full TCP/IP offload via its TCP Offload Engine ( TOE ) under Linux and TCP Chimney under Windows. For block storage, Terminator Series ( Terminator 4 (T4) and Terminator 5 (T5) ) supports both partial and full iSCSI offload, where the ASICs offload processing intensive tasks such as PDU recovery, header and data digest, CRC generation/checking, and direct data placement (DDP).
Chelsio’s Terminator Series ( Terminator 4 (T4) and Terminator 5 (T5) ) adapters are capable of performing full offload iSCSI as both iSCSI initiatior and iSCSI Target at 1Gbps, 10Gbps, 40Gbps. Click here to read more…
Just as computing power moved to decentralized networks of computers, storage technology has also evolved from host-centric direct-attached storage to network-centric storage area networks (SANs). One of the great challenges facing the storage industry has been how to provide reliable and manageable service over a network of inexpensive storage systems.
Fibre Channel vs. iSCSI
In today’s SANs, Fibre Channel (FC) — featuring high bandwidth, low latency and advanced flow control for burst storage transfers — is the most popular method for connecting storage devices to networked clients. Fibre Channel (FC) does have some drawbacks, including:
Each of these disadvantages ultimately adds to Fibre Channel (FC)’s excessive total cost of ownership. To overcome the problems with Fibre Channel (FC), the storage industry recently developed iSCSI, a new technology which allows a storage network to be built based on the popular TCP/IP protocol and Ethernet. The iSCSI (iSCSI offload) technology features the following benefits:
With the introduction and standardization of iSCSI, Ethernet has become a viable connectivity that development, combined with the 10 GbE and now 40GbE with offload capabilities, overcomes the traditional objections about Ethernet-based storage networks: low bandwidth, high latency, and lack of flow control. Chelsio has taken a leading role in this market segment with the introduction of the Terminator iSCSI/TOE HBA/NIC’s. The Terminator Series ( Terminator 4 (T4) and Terminator 5 (T5) ) stands out as the leading Ethernet storage networking building block thanks to its record throughput and IOPS, as well as its Ethernet-based technology. Chelsio’s Terminator Series ( Terminator 4 (T4) and Terminator 5 (T5) ) has greater throughput and lower latency than competing technologies, and is driving the convergence of LANs, SANs and NAS by supporting multiple protocols. With the Chelsio Terminator Series ( Terminator 4 (T4) and Terminator 5 (T5) ), 40GbE/10GbE/1GbE iSCSI (iSCSI offload) is real and available.
Chelsio Communications, a leading provider of 10Gb Ethernet (10GbE) Unified Wire Adapters and ASICs, today announced the availability of the first set of 40Gb Ethernet (40GbE) network adapters based on the fifth generation of its hyper‐virtualized unified wire Terminator ASIC architecture. The Terminator 5 (T5) powered adapters are the industry’s highest performance Ethernet interfaces, delivering wire speed bandwidth, ultra low latency and high message processing capacity. With a comprehensive suite of offloaded storage, compute and networking protocols – including RDMA, TCP/IP, UDP/IP, iSCSI and FCoE with T10‐DIX – Terminator 5 (T5) enables network convergence and provides unprecedented performance in virtualized environments, while dramatically increasing host system efficiency and lowering communications overhead.

At SNW Spring 2012, Chelsio demonstrated 1.1 M IOPs on a Unified Storage Server system using the Chelsio T4 Unified Wire Adapter. At SNW Fall 2012, Chelsio raised the bar by demonstrating a system that does 2 M IOPs using off-the-shelf hardware. The 2.1M IOPs was to a RAM Disk to establish the capability independent of the # of SSD cards. Once access was made to the 5 SSD cards in the system, 1.7M IOPs were observed. Read More…

Nevertheless, FC addressed the real need for scalable storage area networks (SANs), and has since been widely deployed. Some of this resiliency to competing technologies may be explained by storage centric capabilities and
reliability, offloaded hardware implementations and a dedicated ecosystem. A speciaized technology, FC has kept largely ahead of Ethernet in terms of storage features and performance.Read More…
