Need for Virtualization

66

Today’s enterprise computing environments

are multi-platform for a reason. They’re

optimized to run different workloads:

– Database and Transaction processing.

– Analytics.

– Web-based interactions.

– Enterprise applications such as ERP.

– The myriad of x86 applications.

Complex solutions are optimally deployed

on multi-tier heterogeneous infrastructures

And cost less on IBM System z®….

Despite the Allure of a “one size fits all”

Server Approach …

A Fundamental Shift in Costs, Driven by x86 Sprawl

Sizing Estimate – zEC12

This chart shows, in terms of MIPS, the capacity needed to support the

workload. A zEC12 with 16 IFL engines is the target machine.

For this workload we can expect the 16 IFL engines to be 82% busy.

26

This chart compares the cost of energy for 73 distributed servers to

the cost for one zEC12 with 16 IFL engines.

Sizing Estimate – zEC12

This chart shows, in terms of MIPS, the capacity needed to support the

workload. A zEC12 with 16 IFL engines is the target machine.

For this workload we can expect the 16 IFL engines to be 82% busy.

Energy Savings

This chart compares the cost of energy for 73 distributed servers to

the cost for one zEC12 with 16 IFL engines.

Basics of Linux Memory Management

• The Linux OS was built to run on hardware that had slow I/O

subsystems. Therefore it buffers all I/O to “Buffer” and “Cache”

areas.

• Linux will consume all available memory as buffer/cache.

• This raises it’s memory footprint in z/VM.

• There is no way to prevent the Linux kernel from using available memory

as buffer/cache.

• So, we define Linux guests to have the smallest memory size

possible, so that you can run many of them while buying the

least real memory.

• Use z/VM VDISKs for swap disks.

• Allocate no more than 15% of the guest size to the swap file size. This

small swap file ensures that Linux will not be able to heavily swap.

Remember, we want z/VM to do the heavy lifting when it comes to paging

virtual memory.

51

Real Memory guidance

Using the Conservative ratio, 84 GB of real memory is the suggested starting

point. Actual results in production may show either higher or lower

requirements.

52

Why Good Memory Allocation for Linux is

Important

53

zSeries Advantages

• zEnterprise Network Performance, Throughput,

and Simplification

– HiperSockets

• Up to 32 high-speed virtual LAN attachments

– Virtualized network switches

• zEnterprise Positioning for Disaster Recovery

• zEnterprise for Systems Management

– With Single System Image, z/VM has the ability to move

guests through the Live Guest Relocation facility, also new in

z/VM 6.2.

• zEnterprise Environmentals
