4 IBM System x3850 X6 and x3950 X6 Planning and Implementation Guide
Hypervisors struggle to manage and share the heavy I/O loads typical of
performance-intensive workloads. As a result, performance-intensive databases used for
core enterprise workloads, such as CRM, ERP and SCM, are left to run on physical,
non-virtual servers.
The next wave of server virtualization with IBM X6 will expand virtualization footprint to the
workhorse applications of enterprise IT, namely those performance-intensive databases.
IBM X6 makes virtualization of mission-critical, performance-intensive workloads possible in
a number of ways:
IBM FlashCache Storage Accelerator intelligent caching software makes it possible to
virtualize high-performance databases and applications and increases per server VM
density. Customers deploying FlashCache Storage Accelerator can recognize up to a 10X
improvement in IOPS performance, up to 5X faster rich-media web page loads, and
reduces I/O load and increased performance in primary storage. For more information
about FlashCache Accelerator see 1.5, “Flash storage” on page 8.
IBM X6 support for an integrated hypervisor: All x3850 X6 and x3950 X6 models support
the addition of an internal USB key with VMware ESXi installed.
Workload optimized models have been designed to take the guesswork out of deciding
what the best components are for a given workload.
Processor support: The Intel Xeon Processor E7-4800/8800 v2 series support Intel
Virtualization Technology (Intel VT) Flex Priority and Intel VT Flex migration.
Large VM support for enterprise applications:
– Virtualized SAP HANA on X6
– VMware vCloud Suite on X6
– Microsoft Hyper-V Private Cloud on X6
1.1.4 Enterprise applications: ERP and CRM
Enterprise applications, such as Enterprise Resource Planning (ERP) or Customer
Relationship Management (CRM), represent a mixed workload where both transaction
processing and certain level of real-time reporting exist. In a 2-tier implementation, both
database server and application modules reside on a same server. The key performance
metric is response time, as with OLTP and OLAP workloads.
IBM X6 offerings provide low latency, extreme performance, and efficient transaction
management to accommodate mixed workload requirements. IBM X6 in-memory and flash
storage offerings can help to deliver the following benefits for enterprise applications:
Dramatically boosting the performance of existing applications and lowering cost per IOPS
ratio without a need to redesign the application architecture.
Increasing user productivity with better response times, improving business efficiency.
Increasing data availability by using advanced system-level high availability and reliability
technologies, reducing the number of solution components and shortening batch
processing and backup times.
Increasing storage performance and capacity while decreasing power, cooling and space
requirements.
