The 32Gb Fibre Channel (GFC) QME2742-DEL is the industry’s rst 32GFC dual-port
mezzanine adapter, created for the Dell® modular chassis platform. Designed with full
hardware ofoads, the QME2742-DEL boasts industry-leading native Fibre Channel (FC)
performance with extremely low CPU usage.
32GFC Technology
Marvell 32GFC mezzanine solution offers higher per-port performance (up to 650K
IOPS) with lower power consumption. In addition, Marvell StorFusion
TM
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.
Marvell QLogic FC technology resolves data center complexities by enabling a storage
network infrastructure that supports powerful virtualization features, applica-
tion-aware services, and simplied 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 32GFC, all-ash arrays (AFAs), and demanding enter-
prise 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 1.3million IOPS for physical, virtual, and private cloud
environments. Marvell QLogic adapters deliver the best storage application perfor-
mance in both virtualized and non-virtualized environments with up to 12,800MBps of
aggregate throughput.
Virtualization Optimized
The Marvell QLogic QME2742-DEL mezzanine adapter supports standards-based
virtualization features. Under VMware® ESXi6.7, 7.
x
, and later, 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 virtual-
ization (NPIV) enables a single FC adapter port to provide multiple virtual ports for
increased network scalability. Standard class-specic control (CS_CTL)-based QoS

Marvell® QLogic® QME2742-DEL
Dual-Port, 32GFC Fibre Channel Mezzanine Adapter
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.
Marvell StorFusion Technology
Marvell QLogic 32GFC 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
Marvell 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 identication 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) capabili-
ties, 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 indus-
try-standard class-specic control (CS_CTL)-based frame prioritization QoS, which helps
alleviate network congestion. When Dell adapters with Marvell StorFusion technology
are connected to supported SAN fabrics, trafc is classied as it arrives at the switch,
and is then processed on the basis of congured priorities. Trafc 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 trafc for optimized
performance.
Higher Resiliency and Performance with Automatic Error Recovery
FEC is automatically used at 32GFC as required by the
Fibre Channel Specication
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.
