OVERVIEW

The QLogic QME2742-DEL is the industry’s rst Gen6 FC dual-port

mezzanine adapter. Designed with full hardware ofoads, the

QME2742-DEL boasts industry-leading native FC performance with

extremely low CPU usage.

GEN 6 FC TECHNOLOGY

QLogic Gen 6 FC technology provides the industry’s rst 32GFC

mezzanine adapter. QLogic’s Gen6 FC solution offers higher per-port

performance (up to 650K IOPS) with lower power consumption. In

addition, QLogic StorFusion technology delivers streamlined provisioning,

guaranteed QoS, and improved resiliency with built-in forward error

correction (FEC). These features address the needs of IT organizations

that require reliability, integrated management, and guaranteed network

performance.

Gen6 FC technology resolves data center complexities by enabling a

storage network infrastructure that supports powerful virtualization

features, application-aware services, and simplied management. The

QME2742-DEL mezzanine adapter provides advanced storage networking

features capable of supporting the most demanding virtualized and private

cloud environments. This adapter fully leverages the capabilities of high-

performance Gen6 FC, all-ash arrays (AFAs), and demanding enterprise

applications. Powerful management tools automate and simplify SAN

provisioning to help reduce cost and complexity, while the unmatched

32GFC line rate performance eliminates potential I/O bottlenecks in today’s

powerful multiprocessor, multicore servers.

SUPERIOR PERFORMANCE

The QME2742-DEL mezzanine adapter can accelerate mission-critical

enterprise applications by delivering up to 1.3million IOPS for physical,

virtual, and private cloud environments. QLogic adapters deliver the best

storage application performance in both virtualized and non-virtualized

environments with up to 12,000MBps of aggregate throughput.

VIRTUALIZATION OPTIMIZED

The QLogic QME2742-DEL mezzanine adapter supports standards-based

virtualization features. Under VMware

ESXi6.0 and 6.5, I/O requests

and responses can be tagged with the virtual machine-ID (VM-ID) of the

appropriate virtual machine, providing end-to-end visibility at the VM level.

Support for N_Port ID virtualization (NPIV) enables a single FC adapter port

to provide multiple virtual ports for increased network scalability. Standard

class-specic control (CS_CTL)-based QoS technology per NPIV port

allows bandwidth controls and guarantee per VM. In addition, the 32GFC

line rate per physical port delivers unmatched storage performance to

maximize the quantity of VMs per physical server.

Data Sheet

QLOGIC STORFUSION TECHNOLOGY

QLogic Gen6 FC mezzanine adapters powered by StorFusion technology

include advanced capabilities that are enabled when deployed with

supported Brocade

switches. By combining these industry-leading

solutions, SAN administrators can take advantage of enhanced features

that improve availability, accelerate deployment, and increase network

performance. StorFusion solves the top issues for SAN administrators

worldwide.

Improved TCO and Reliability

QLogic technology includes the read diagnostic parameters (RDP) feature,

which provides detailed port, media, and optics diagnostics while the link

is in service. From any point in the fabric, an administrator can use RDP

to easily access diagnostic information, thereby enabling identication of

link-related errors and degrading conditions on any N_Port-to-F_Port link.

The extensive suite of diagnostic tools maximizes uptime and

performance, allowing organizations to address problems before they

impact operations.

Rapid Server Deployment and Orchestration

StorFusion technology includes fabric pre-provisioning services that enable

servers to be quickly deployed, replaced, and moved across the SAN. By

leveraging fabric-assigned port world wide name (FA-WWN) and fabric-

based boot LUN discovery (F-BLD) capabilities, the creation of zones,

LUNs, SAN-based boot images, and other services can be completed

before the servers arrive on site—eliminating time-consuming, manual

tasks that typically delay server deployment.

Performance SLA Enforcement with VM-level QoS

Network performance can be dramatically improved by implementing

the industry-standard class-specic control (CS_CTL)-based frame

prioritization QoS, which helps alleviate network congestion. When Dell

adapters with QLogic StorFusion technology are connected to supported

SAN fabrics, trafc is classied as it arrives at the switch, and is then

processed on the basis of congured priorities. Trafc can be prioritized

for delivery or subjected to limited delivery options. As a result, mission-

critical workloads can be assigned a higher priority than less time-

sensitive network trafc for optimized performance.

Higher Resiliency and Performance with Automatic Error Recovery

FEC is automatically used at 32GFC as required by the

Fibre Channel

Specication

to improve performance and link integrity. FEC automatically

detects and automatically recovers from bit errors, which results in higher

availability and performance.

Automatic buffer-to-buffer credit recovery (BB-CR) helps overcome

performance degradation, congestion, and link resets caused by buffer

credit loss, especially on longer-distance and high-loss ber connections.

SIMPLIFIED MANAGEMENT

The QLogic unied management application, QConvergeConsole

(QCC),

provides single-pane-of-glass management across generations of QLogic

FC adapters. In addition, QLogic supports all major APIs for deployment

exibility and integration with third-party management tools, including

VMware vCenter

™

and Brocade Network Advisor.

HIGH AVAILABILITY AND RELIABILITY

QLogic Gen6 FC mezzanine adapters continue the tradition of providing

complete port-level isolation across the FC controller architecture. This

architecture, unlike other vendor solutions, provides independent function,

transmit and receive buffers, an on-chip CPU, DMA channels, and a

rmware image for each port. These features enable complete port-level

isolation, prevent errors and rmware crashes from propagating across

both ports, and provide predictable and scalable performance across both

ports. The QLogic architecture delivers ultimate reliability to meet the

needs of mission-critical enterprise applications, with lower power and

fewer CPU cycles, all while maintaining peak performance.

In addition, overlapping protection domains (OPDs) ensure the highest level

of reliability as data moves to and from the PCI

bus and FC network.

The QME2742-DEL mezzanine adapter also provides end-to-end data

integrity with support for T10 Protection Information (T10 PI), which

prevents the risk of silent data corruption in environments running Oracle

Linux

with the Unbreakable Enterprise Kernel.

LEADERSHIP, CONFIDENCE, AND TRUST

The QLogic QME2742-DEL mezzanine adapters are compatible with

the same FC software driver stack that has been tested and validated

across all major hardware platforms, as well a all major hypervisors, and

operating systems.

Cavium technology makes it the undisputed leader in FC adapters, with

over 20years of experience, more than 20million ports shipped, and

multiple generations of FC products that have been the leading choice of

Cavium customers. Cavium owns the most established, proven FC stack in

the industry, with more FC ports shipped than any other vendor.
