OVERVIEW

SERVER CONNECTIVITY FOR NEXT-GENERATION DATA CENTERS

Today’s IT professionals face the difficult challenge of reducing data center cost and complexity while satisfying numerous service-level agreements (SLAs) and performance requirements. As a result, organizations are seeking ways to improve server and storage usage, reduce ongoing operational costs, and increase their flexibility and responsiveness.

Two major industry trends aimed at reducing cost and complexity— server consolidation and virtualization—have quickly become the highest priorities for server administrators. Most data centers were designed

to meet basic connectivity needs for physical servers, switches, and storage. However, consolidation and virtualization drive new connectivity requirements that legacy solutions are no longer able to meet, such as streamlined manageability, increased performance, and virtualization awareness. Performance of the applications under load and manageability are often critical concerns for organizations deploying server virtualization.

The BR-815 and BR-825 Fibre Channel adapters are a new class of server connectivity products with unmatched hardware capabilities and unique software features. This new class of adapters is designed to help IT organizations deploy and manage end-to-end SAN services across nextgeneration data centers.

CENTRALIZED ADAPTER MANAGEMENT

QLogic’s Host Connectivity Manager (HCM) is an easy-to-use adapter management tool for configuring, monitoring, and troubleshooting the QLogic BR-series adapters. HCM enables server administers to quickly configure BR-series adapters locally or remotely.

HCM scans the SAN environment to discover visible storage resources and display target LUNs. A simple to use graphical tree view provides fast access to the managed Host Bus Adapters, Converged Network Adapters, ports, and target storage resources. HCM also provides notifications of various conditions and problems through a user-defined event filter.

In addition to providing a graphical interface, QLogic also provides a powerful command line interface (BCU CLI), for scripting and task automation.

For holistic data center wide management, QLogic HCM is tightly integrated with Brocade® Network Advisor (BNA) to provide end-to- end configuration and management of the entire SAN infrastructure.

Administrators can launch QLogic HCM from within BNA to provide single- pane-of-glass management of QLogic BR-series adapters and Brocade switches.

QLogic also provides open APIs and standards-based interfaces for integration with popular third party applications.

QLogic adapters also enable VM discovery in VMware® ESX® environments within BNA. VM discovery provides an end-to-end view of the VM-to-

LUN path information for all the VMs running on each physical server, with detailed information such as host OS, assigned CPU and memory resources, and all the data stores associated with each VM. This level of visibility into the virtual server infrastructure for SAN administrators

enables them to more efficiently manage their storage network resources. Coupled with N_Port ID virtualization (NPIV), Network Advisor can also provide end-to-end performance statistics with VM granularity, increasing visibility down to the LUN level.

Boot-over-SAN enables the deployment of both direct-attached storage (DAS) point-to-point topology as well as diskless servers and centralized management of OS images in the shared storage pool. Traditional boot- over-SAN environments, however, require access to each individual adapter BIOS (and each individual server console), making them cumbersome to configure, laborious to maintain, and prone to human error. To simplify the management of boot-over-SAN environments, QLogic adapters provide fabric-based boot LUN discovery—a feature that enables each server to automatically retrieve its boot LUN information from the switch fabric. Boot LUN discovery provides a centralized management point for all boot-over-SAN operations, enabling organizations to fully

reap the benefits of diskless servers. In addition, to account for the disk spinup delay time when servers and storage devices are powered on simultaneously, users can configure a 1-, 2-, 5-, or 10-minute delay to boot with the boot-up delay feature.

UNMATCHED PERFORMANCE

With the recent advances in server technology, including Intel® Romley processors, servers are now capable of running more workloads than ever. This increased capacity drives higher consolidation and virtualization ratios, with more VMs being deployed per server, which in turn drives unprecedented I/O requirements. The superior performance of QLogic adapters provides the necessary bandwidth and I/O power for the most demanding environments.

Ultimately, increased performance means that businesses of all sizes can scale their virtual server deployments and virtualize highly demanding applications with greater confidence, resulting in better server resource utilization and lower capital and operational costs.

OPTIMIZED FOR VIRTUAL ENVIRONMENTS

In a non-virtualized environment, every application is tied to a physical server, which in turn connects to a physical SAN switch port in a “static” manner. Applying network policies such as zoning or QoS—or

monitoring application performance—is simple because the application is permanently associated with the physical port.

With server virtualization, multiple applications reside in a physical server and share a physical SAN port. Furthermore, applications can move across the virtualized server infrastructure, based on a number of user-defined policies, to respond to dynamic business requirements. A virtualizationaware SAN infrastructure and server connectivity solution enables organizations to apply network policies at the VM level. Such policies will then be able to “follow” the application transparently as it moves to a new physical server.

QLogic adapters were built from the ground up with virtualization in mind. They support NPIV with up to 255 virtual ports, and they are qualified with all major hypervisor solutions in the industry. Leveraging NPIV technology, organizations can not only extend QLogic fabric services to the server, but all the way to the VM and application level. Brocade Server Application Optimization (SAO) helps IT organizations avoid downtime and more effectively meet their SLAs by allowing them to apply QoS policies with a per-VM granularity and ensure that mission-critical VMs will not be affected in the event of adapter link congestion—even as they move across the infrastructure. SAO also provides isolation to protect individual

VMs from the effect of slow-drain devices that would otherwise impact the entire physical server and all applications.
