Chelsio Intros Integrated 10 GbE Drivers for Citrix XenServer 4.1

Chelsio Communications (News - Alert), a provider of Ethernet adapters and application specific integration circuit (ASIC) solutions, announced Monday the release of new software drivers designed for full integration with Citrix Systems’ (News - Alert) XenServer 4.1. These “In-Box” drivers enable seamless deployment of Chelsio’s 10GbE Unified Wire adapters with Citrix XenServer 4.1.

The deployment uses Chelsio’ Unified wired technology and provides high I/O performance for single or multiple Windows and Linux virtual machines (VM).
Using its Unified Wire technology, specializes in the convergence of networking, storage and clustering. The company mainly ships 10-Gigabit Ethernet and multi-port Gigabit Ethernet adapter cards that provide high-performance computing applications with low latency and superior throughput. Chelsio is also a Citrix Ready partner.
Chelsio’s 10GbE Unified Wire adapters are based on 3G T3 ASIC technology, offering high bandwidth with low latency.
The ‘In-Box’ drivers for XenServer 4.1 have been passed through a rigorous qualification process by both companies. Becoming certified means Chelsio is now included in the Citrix hardware compatibility list. The qualification enables and confirms seamless deployment of Chelsio 10GbE Unified Wire adapters with Citrix XenServer 4.1.
“Chelsio’s integrated 10 GbE drivers for XenServer 4.1 are very easy to use, and can substantially boost the network performance of virtualized environments,” said Jason Timmins, technical director at InterLinx, Ltd, a UK-based Internet service provider, in a statement. “We can now run even more network-intensive workloads on each virtual machine without sacrificing application performance.”
Citrix XenServer 4.1 provides enhanced scalability and faster performance along with capabilities for conducting virtual infrastructure platform upgrades and automated patching with zero downtime. The newly released 4.1 version of Citrix XenServer also features new capabilities such as support for 10 GB/s networking, bonding, and 64-bit enterprise Linux guests.  
“Chelsio’s 10GbE drivers for XenServer 4.1 deliver line-rate performance, which greatly boosts the value of XenServer 4.1 for the range of high-throughput applications,” said Matt Fairbanks, vice president of product marketing for XenServer at Citrix, in a statement. “Our customers can now run their most network-intensive workloads on their virtual servers and achieve the best overall performance in the industry.”
“Virtualization support is a key attribute of our T3 unified wire technology, and we are pleased to be the only vendor in the industry that has delivered full 10G line-rate I/O performance for virtualized server environments using a single VM,” said Kianoosh Naghshineh, president and CEO of Chelsio, in a statement. “Citrix’s customers enjoy the cost benefits and richness of XenServer 4.1 virtualization while maintaining the performance and cost advantages of Chelsio’s unified wire solutions.”
Chelsio is conducting demonstrations of its virtualization solutions the Interop (News - Alert) show this week in Las Vegas.
