Marvell QLogic QME2742-DEL Adapter
Product Brief
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.
