  • Data Sheet QLE8152 Dual Port 10Gbps Enhanced Ethernet to Pcie Converged Network Adapter
    D ATA S H E E T Third party information brought to you courtesy of Dell. QLE8152 Dual Port 10Gbps Enhanced Ethernet to PCIe Converged Network Adapter Fibre Channel over Ethernet (FCoE) Technology. FCoE provides an opportunity to reduce data center costs by converging data and storage networking. Standard TCP/IP and Fibre Channel traffic can both run on the same high speed 10Gbps Ethernet wire, resulting in cost savings High Performance through reduced adapter, switch, cabling, power, cooling, and management requirements. FCoE has gained rapid market traction because it delivers • 10Gbps per port maximum throughput for high excellent performance, reduces data center TCO, and protects current data bandwidth storage (SAN) and networking (LAN) center investment. traffic • Full hardware offload for FCoE protocol processing iSCSI. The QLE8152 even supports iSCSI storage protocol using iSCSI • 250,000 IOPS per port deliver high I/O transfer software initiators, which are available with all major operating systems. rates for storage applications • Full support for TCP/IP and Ethernet performance High Performance. The QLE8152 boosts system performance with 10Gbps enhancements such as priority-based flow control speed and full hardware offload for FCoE protocol processing. Cutting edge (802.1Qbb), jumbo frames, checksum offloads, and 10Gbps bandwidth eliminates performance bottlenecks in the I/O path with segmentation offloads a 10X data rate improvement versus existing 1Gbps Ethernet solutions. Additionally, full hardware offload for FCoE protocol processing reduces Lower Total Cost of Ownership (TCO) system CPU utilization for I/O operations, which leads to faster application performance and higher levels of consolidation in virtualized systems. • Reduced hardware, cabling, power, cooling, and management costs through convergence of data Lower TCO.

  • Implementing Fibre Channel SAN Boot with Oracle's Sun ZFS Storage Appliance
    Implementing Fibre Channel SAN Boot with Oracle's Sun ZFS Storage Appliance August 2012 By Tom Hanvey; update by Peter Brouwer This paper describes how to implement a Fibre Channel (FC) SAN boot solution using Oracle's Sun ZFS Storage Appliance on a high-availability SAN. This solution has been validated with a variety of servers, operating systems, and hardware configurations. Introduction Overview Benefits of Booting from a SAN FC SAN Boot Configuration Requirements Configuring the Sun ZFS Storage Appliance for Fibre Channel Boot Configuring the Client Server for Fibre Channel SAN Boot Installing the Operating System on the Server FC SAN Boot Time Test Results Best Practices Conclusion Appendix: References Introduction Organizations are continually looking for ways to simplify their management infrastructure, enhance scalability, and reduce costs while increasing reliability and performance in their data center. Booting from a storage area network (SAN) offers many benefits, leading to cost savings as well as higher levels of protection, ease of management, increased flexibility, and reduced down time. Traditionally, operating systems have been installed on internal disks on individual servers or on direct attached storage (DAS). This approach presents a number of challenges to an IT organization. Dedicated internal boot devices cannot be shared with other servers, so are often underutilized. IT staff must perform management tasks on these systems locally rather than from a central management system, leading to increased administrative costs. For optimal redundancy and performance, additional RAID software or host bus adapters (HBAs) are required to manage these storage devices. Local disks on individual servers present particular challenges for multi-site administration and disaster recovery site maintenance.

  • IBM Bladecenter : Qlogic Virtual Fabric Extension Module
    IBM Europe, Middle East, and Africa Hardware Announcement ZG09-0804, dated December 15, 2009 IBM BladeCenter : QLogic Virtual Fabric Extension Module Table of contents 1 Overview 2 Product number 2 Key prerequisites 3 Technical information 2 Planned availability date 4 Terms and conditions 2 Description 5 Prices 2 Product positioning 6 Announcement countries At a glance The QLogic Virtual Fabric Extension Module is the latest Ethernet switching option for the IBM® BladeCenter®. This offering allows BladeCenter integration with virtually any open-standards-based local area network (LAN). Overview Blades have made inroads into enterprise data centers by delivering higher density with a lower footprint and reduced costs for power and cooling compared to traditional rack servers. Now with multicore environments, there is an increased need for faster I/O such as 10 Gb Ethernet. QLogic Virtual Fabric Extension Module for IBM BladeCenter IBM has been at the forefront of offering new technology to clients. The QLogic Virtual Fabric Extension Module is another example of IBM's innovation. IBM was among the first to deliver Fibre Channel over Ethernet (FCoE) across System x® and BladeCenter and this new module takes this a step further by offering clients IO convergence inside the chassis. Clients using the BNT 10 Gb switch (part number 46C7191) for their LAN traffic can now combine it with this module and the QLogic CNA (#42C1830) to converge their LAN and SAN on a single network. This not only offers a simplified fabric, but also offers significant savings over separate 10 Gb/8 Gb infrastructure. Other than the cost and management savings, this solution provides the flexibility to upgrade existing chassis to implement IO convergence without replacing existing 10 Gb switch.
