In Transacon-Intensive and Bandwidth-Intensive Environments
For virtualized environments, the most crical measure of performance is the ability to scale as the number
of VMs and applicaon workloads increase. In tesng conducted by QLogic, the QLogic QLE2672 delivered
three mes the transacons and double the bandwidth of 8Gb Fibre Channel Adapters. The superior
performance of QLogic Gen 5 Fibre Channel Adapters translates to support for both higher VM density and
more demanding Tier-1 applicaons.
QLogic achieves superior performance by leveraging the advanced Gen 5 Fibre Channel and PCIe Gen3
specicaons—while maintaining backwards compability with exisng Fibre Channel networks. The unique
port-isolaon architecture of the QLogic FlexSuite Adapters ensures data integrity, security, and
determinisc scalable performance to drive storage trac at line rate across all ports.
More Virtual CPUs for Scaling Tier-1 Apps
If you’re concerned about hosng Tier-1 apps on VMs, the argument about virtualizing Tier-1 apps is over.
Even agship enterprise applicaons such as Microso SQL Server 2012 and Exchange 2010 have adopted
server virtualizaon as a best pracce. In fact, the CPU,
memory, storage, and networking requirements are
well documented by Microso.
In the example on the right, a mission-crical OLTP
workload running on a single SQL Server 2012 VM
demonstrates linearly increasing transaconal
performance and reduced transacon response mes
as the number of virtual CPUs assigned to the
workload are increased to the maximum of 64 now
supported on Hyper-V.
Scalability with Gen 5 Fibre Channel
Throughput
Gen 5 oers a 3X bandwidth advantage and a 2X throughput
advantage over 8Gb Fibre Channel.
Virtual CPUs were increased from 4 to 64, increasing the
number of transacons per second. Hyper-V scaled
eciently while decreasing the average response me.
