Notes:
Performance is in Internal Throughput Rate (ITR) ratio based on measurements and projections using standard IBM benchmarks in a controlled environment. The actual throughput that any
user will experience will vary depending upon considerations such as the amount of multiprogramming in the user's job stream, the I/O configuration, the storage configuration, and the
workload processed. Therefore, no assurance can be given that an individual user will achieve throughput improvements equivalent to the performance ratios stated here.
IBM hardware products are manufactured Sync new parts, or new and serviceable used parts. Regardless, our warranty terms apply.

achieved. Actual environmental costs and performance characteristics will vary depending on individual customer configurations and conditions.

Sugestões de calibragem
 O fator calculado é por volta de 10%. O método recomendado é fazer a
calibragem por CPs :
Capacidade por CP = Capacidade total / #CPs
Calibragem = (%Utilização * #CPs ) / 0.9
Calibragem = (0.5 * 10) / 0.9 = 5.55  6
Com base na capacidade da zEC12-706 no zPCR seria 7.577
Sendo a capacidade por processador 7.577 / 6 = 1.263 (contra 1.217)
 Se assumirmos uma estimativa menos conservadora poderiamos estimar
10% sobre o valor inicial :
Calibragem = (%Utilização * Capacidade total ) * 1,10
Usando o exemplo teriamos (0.5 * 12172) *1,10 = 6.694,6  6.695
 Assim teriamos :
Range 6.695 a 7.577 no total

Mobile workload Pricing
 Oferta para cargas “Mobile”
 Anunciado 6 de maio 2014
 Disponível Julho 2014
 Exige que a instalação possua ao menos uma z13, zEC12 ou zBC12,
embora outros CECs com z196 ou z114 da mesma instalação possam se
beneficiar.
 Retira 60% das MSUs(segundos de CPU ) gerados por requisições
“mobile” (geradas por tablets ou smartfones).
 O impacto de custo varia em função do perfil de uso de software e do
R4HA .

Country Multiplex Pricing (CMP)
 “Evolução” do Sysplex pricing
 Medição consolidada para um mesmo cliente dentro de um mesmo País.
 Pré-anunciado em 14 de Janeirol
 Ainda sem data de disponíbilidade
 zEnterprise (z13, zEC12, zBC12, z196, z114)
 Permite consolidar as MSUs de varios CECs
Processo de transição usa um baseline de custo (possivelmente sem
impacto de custo inicial )

Traditional Sub-Capacity Peak = Sum of individual SCRT machine peaks for the month:
Machine 1: 145

Sum of Peaks: 435
Multiplex Peak = Peak value of the hourly
simultaneous totals of all machines
Peak of Simultaneous Totals: 385
• Cada barra representa o número de MSUs medidos em um intervalo
• Assumindo 3 intervalos no mes :
Reporting dynamics
Multiplex MSUs will be at or below SCRT
values due to the smoothing effect of
measuring all machines at the same time
