SOFTCAP

OVERVIEW


SOFTCAP• Allows you to evaluate CPU, real storage impact of a

migration from OS/390 V1.1 through z/OS V1.6• Options

– ESA/390 vs. z/Architecture, or 31-bit vs. 64-bit– WLM Compatibility vs. Goal Mode– Demand Paging to/from Expanded Storage– RSM Services Intensity

• CICS, IMS release migration estimation is also provided– CICS/ESA V3.1.1 through CICS TS V2.3 + MRO (FOR, AOR, TOR)– IMS V3 through V8 + Fast Path & Full Function

• You can specify workload % for CICS, IMS, DB2, TSO, batch, and system where total = 100%

• Requires Java Runtime 1.4.1, part of download package• www.ibm.com/support/techdocs/atsmastr.nsf/WebIndex/PRS268

CONCLUSIONS• The mean CPU utilization increase between OS/390 V2.10 &

z/OS V1.4 is 1.26%, 1.38% for V1.4.2, 1.56% for V1.5– For 31-bit to 31-bit or 64-bit to 64-bit– z/OS V1.6 only requires .5% more

• The mean CPU increase between OS/390 V2.10 & z/OS V1.4 is 4.4%, 4.5% for V1.4.2, 4.76% for V1.5, 3.6% for V1.6– For ESA mode/31-bit to zArchitecture/64-bit migration

• The CPU increase between z/OS V1.2 & V1.4 through V1.5 is between .4% and .7%, V1.6 is actually a decrease of .34%– The increase between V1.4 & V1.5 is .34%, V1.6 is a .8%

decrease

• Batch processing appears to benefit the most from z/OS V1.6 • In zArchitecture/64-bit mode, OS/390 requires the least

storage (35M), z/OS V1.2, V1.4, & V1.4.2 the most (42M), and V1.5/ V1.6 requires marginally more than OS/390 V2.10 (37M)

• z/OS V1.6 is the best performing z/OS release

CP2000• Uses RMF or SMF input• Analyzes and estimates processor utilization,

workloads, storage usage, and I/O performance• Evaluates parallel sysplex• Simulates zSeries performance

– ITR ratios and partitioning costs are derived from zPCR– LSPR data is also factored in

• Simulates non-zSeries performance– PCRW data is used instead of zPCR data– LPAR/CE is used to estimate partitioning overhead

• Results are shown in Smart Tex format– Graphs and charts are included

• Techline provides support at 1(888)426-5525 or http://www.ibm.com/support/americas/atechline.html


zPCR• zPCR is comprised of LSPR ITR ratios and detailed LPAR

configuration detail that predict performance/capacity• Capacity figures are derived from user-defined values

– User-selected processors– Scaling-factor and scaling metric

• Processor Capacity Tables include standard CPs, ILF CPs– z/OS, z/VM, and Linux workload-based LPAR configurations are

supported– LSPR workload primitives, predefined workloads, user-defined

workloads can be used• Primitives and predefined workloads are different mixes of work, such

as transaction intensive, batch intensive, blends of the 2, Websphere, Linux, and I/O intensive

• LPAR configurations include traditional, IFL, and ICF CPs– Capacity assessment is performed for each LPAR and overall host


Non-zSeries Tools• PCRW provides similar function to z/PCR for processors

and LPAR configurations on pre-zSeries processors– OS/390, VM/ESA, and VSE/ESA environments are supported– Evaluates processor consolidation as well– Sizes applications– Analyzes workload growth– Analyzes workload characteristics

• LPAR/CE evaluates LPAR performance/capacity for pre-zSeries processors– Provides detailed LPAR capacity analysis and planning

information

• These tools can be used in conjunction with zPCR– They can provide capacity data, etc., for processors not

supported by zPCR (for example, upgrade from non-zSeries to zSeries)

– Workloads must be similar and base ITR, scaling, etc. must be similar

• z/OS V1.4 CS versus z/OS V1.2 CS– RR TCP transactions/second is 17.85% better,

cost/transaction is 6.43% better– RR UCP transactions/second is 12.11% better,

cost/transaction is 31.64% better– CRR transactions/second is .66% worse, cost/transaction is

1.8% better– STR transactions/second is .81% better, cost/transaction is

1.24% better


COMBINED COMPARISON

• A hybrid comparison of z/OS V1.4 CS to OS/390 V2.10 CS• Results are extrapolated based on differing measures• Each is expressed in % changed, providing commonality• A “Transput” is a blended measure of transactions per

second and throughput• RR throughput was was not delineated by TCP & UDP• RRTCP transput is 23.55% better than OS/390 V2.10 CS• RRUDP transput is 17.5% better than OS/390 V2.10 CS• Blended RRTCP/UDP transput is 20.55% better than

OS/390 V2.10 CS• CRR transput is 2.34% better than OS/390 V2.10 CS• STR transput is 7.08% better than OS/390 V2.10 CS


FTP SERVER COMPARISON• The 2 benchmarks use similar workloads

– The number of sessions are different, 16 (V1.2) vs. 8 (V1.4)

• Both benchmarks are AIX to MVS• Throughput

– z/OS V1.2 CS vs. OS/390 V2.10 CS single session is 3.75% better– z/OS V1.2 CS vs. OS/390 V2.10 CS multi-session is .08% better– z/OS V1.4 CS vs. z/OS V1.2 CS single-session is 1.98% better– z/OS V1.4 CS vs. OS/390 V2.10 CS multi-session is 2.06% better

• CPU cost per kilobyte– z/OS V1.2 CS vs. OS/390 V2.10 CS single session is 8.12% better– z/OS V1.2 CS vs. OS/390 V2.10 CS multi-session is .32% better– z/OS V1.4 CS vs. z/OS V1.2 CS single-session is 9.43% better– z/OS V1.4 CS vs. z/OS V1.2 multi-session is 9.8% better


BENCHMARK CONCLUSIONS• z/OS V1.4 CS performance is superior to OS/390 V2.10 CS

– RR performance is significantly better– CRR performance is marginally better– STR performance is noticeably better– Single session FTP server gains came with z/OS V1.2 CS– Multi-session FTP server gains came with z/OS V1.4 CS– z/OS V1.2 CS also offers improvements with CLAW packing

• Multiple datagrams in a single channel frame• Improvements were also made regarding CISCO 7200/7500 routers• Results: throughput improved 46.73%, CPU/KB is reduced 13.34%

– z/OS V1.4 CS improves performance for inbound data• 17.25% reduction in CPU cost per kilobyte

– z/OS V1.4 CS Bind V9.2 performs significantly better than V9.1• 186% improvement in trans/sec or more, depending on threads• 44% or greater reduction in CPU per transaction

– The performance impact of IP V6 is negligible


MISCELLANEOUS• z/OS V1.4 CS recommended maintenance

– APAR OW56019– Informational APAR II11952
