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.

Efeito 90%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 )

Simplifica o processo de calculo de MSUs em ambientes com multiplos

CECs.

Permite movimentar cargas entre CECs evitando “dupla cobrança”.





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

Machine 1: 145

Machine 2: 150

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

Allows for dynamic workload movement
