Chelsio launches new unified wire adapters for data centers

Chelsio Communications, a provider of 10Gb Ethernet
Unified Wire adapters and ASICs, announced the launch of T440-LP-CR, a 4x10GbE
Unified Wire adapter that enables 10/40 Gigabit Ethernet connectivity to meet
the high performance demands of data center server and network attached storage

Chelsio has also introduced the
T420-BT, a dual-port 10GBase-T Ethernet adapter.  

Both new adapters are based on the fourth generation T4
technology, and enable a Unified Wire for LAN, SAN and cluster traffic,
providing full offload of TCP, UDP, iSCSI, FCoE and iWARP traffic
simultaneously with support for every major virtualization technology in the

The cards are optimized for cloud computing, HPC, storage
and other data center applications.  Benchmark testing of the T440 showed
saturated throughput for the PCI Express 2.0 interface and latencies of sub 3.0
microsecond for WD-UDP and 5.0 microsecond for TCP traffic.

“There is growing demand for 10GbE in datacenter
server and storage networking, with port shipments in this segment almost
doubling year-over-year,” said Seamus Crehan, president of Crehan

The T440-LP-CR is a 4x10Gb Ethernet, low profile, PCI 2.0
Express bus interface, with 32,000 offloaded connections and one QSFP+ port
that uses standard cables or a single octopus cable that has a QSFP+
transceiver on one end and four SFP+ transceivers on the other end.  This
enables the Unified Wire adapter to deliver 40Gb bandwidth without the need for
a premium 40Gb Ethernet switch port, allowing the lowest cost per gigabit link
in the market.

The T440-LP-CR is particularly well-suited to deliver
storage applications via the high throughput and the ability to run NFS, Lustre
and other file systems over RDMA.  In small storage clusters the
T440-LP-CR easily aggregates four servers into a storage target and removes the
need for additional equipment altogether, resulting in significantly lower IT

The T420-BT is a dual port 10GBase-T Unified Wire adapter
with PCI Express 2.0 host bus interface.  It is capable of providing two
1/10GbE ports by using standard RJ-45 connectors with twisted pair Cat-6a

Chelsio recently announced its Unified Storage Router (USR-1100) appliance has been fully certified
as an iSCSI-to-SAS bridging solution for Quantum’s entry-level Scalar i40/i80
and mid-range Scalar i500 tape libraries.

This certification will enable Quantum resellers to offer
high performance iSCSI SAN solutions to their customers using SAS-based tape
libraries. The Chelsio USR-1100 appliance provides 10Gb iSCSI-to-FC and
iSCSI-to-SAS bridging to both tape and disk storage, enabling enterprises with
FC SAN storage and SAS-based targets to leverage IP networks and extend SAN
advantages into smaller departments and locations, thus leveraging the numerous
benefits of an IP-based solution. These benefits include lower costs, easier
maintenance, and less infrastructure hardware.
