2X More VMs Per Server with vSphere 5.1, Xeon E5, and QLogic Server Adapters
Any concern about hosng Tier-1 apps on VMs has been elevated with vSphere 5.1, Intel E5 processors, and
next-generaon I/O throughput of the QLogic mulprotocol server adapters. Even agship enterprise
applicaons such as SAP, which typically require dozens of development, QA/test, and producon servers,
have adopted server virtualizaon within these environments as a best pracce. The CPU, memory, storage,
and networking I/O requirements are well documented by applicaon vendors and VMware. If one of your
goals is to increase VM density, the same combinaon allows for double the number of VMs per server while
enjoying the same level of individual applicaon performance.
Generaonal Dierences in Performance Using VMware VMmark 2.5
Using the VMware VMmark 2.5 virtualizaon
benchmark, VMware compared the performance of
four-node clusters consisng of servers with four-
core Intel Nehalem processors versus servers with
eight-core Intel EP processors. The new cluster
scored 120 percent higher than the old cluster. The
performance advantages were largely due to the
generaonal improvements of the eight-core E5-
2665 processor versus the four-core x3460
processor, improved bus speeds, increased
memory, and the resulng increase in I/O
throughput.
Having doubled the throughput rates with the
QLogic QLE2672 Gen 5 Fibre Channel Host Bus
Adapter, the vSphere 5.1 plaorm can also support
more storage devices and meet bandwidth
requirements. Now, using the same number of
Fibre Channel links as before can support double
the bandwidth, beneng virtualized applicaons.

Performance Differences in Intel
Generation Using VMware VMmark 2.5
Business-crical applicaons such as ERP, CRM, eCommerce,
and e-mail need high-performance and high-availability I/O
infrastructure to meet business SLAs.
