Grid or Cluster?

Grid e um modelo computacional capaz de alcançar um alta taxa de

processamento dividindo as tarefas em diversas maquinas, podendo ser local ou

a distancia formando uma maquina Virtual;

Cluster são maquinas interconectadas que trabalham em conjunto para que

possam ser vistas como um Sistema Unico;

What is Extended Cluster?

Oracle Maximum Availability Architecture

Oracle MAA defines a reference architecture that addresses availability and data protection• Client applications stop during recovery

• Make decision to failover

• Remote copies of data must be promoted and made read/write enabled

• Database and application consistency must be checked

• Database redo logs must be applied

• Client applications are restarted

• Similar failback process to return production to original site can be painful

RAC VotingFiles

RAC Interconnect

Merged SAN Fabrics

Mirrored I/O paths

Host Mirroring ConsumesValuable CPU Cycles

Cross-Connect Introduces SAN Complexity

DBA becomes a storage admin. Must configure failure groups, path preferences and ASM mirroring functions

As storage capacity and node counts increase, all of the above need to be re-administered for balanced performance and HA requirements

•Losing one site has no impact on availability

– Client Apps continue non-stop

•Restoring original site is also non-disruptive

– Nodes return to processing – without interruption

LAN Backbone LAN BackboneNo host mirroring which savesvaluable CPU cycles

No need to merge fabrics which reduces SAN complexity and improves fault domain isolation

No need for Oracle DBA to configure failure groups, path preferences and ASM mirroring functions

As storage capacity and node counts increase, VPLEX handles path balancing, scaling storage, non-disruptive movement of data and replication workload

No 3rd site voting disk administration as quorum devices reside on VPLEX

Pontos positivos de Utilizar o

Oracle Distance RAC com

Vplex MetroSegurança

Transparente para o Oracle RAC, em nada muda o gerenciamento do ambiente Oracle; Elimina há a necessidade de merge nas SANs para gestão de múltiplas storages; A solução Vplex e homologada pela Oracle/DELLEMC; O Vplex Metro com Oracle RAC e utilizado por Grandes instituições financeiras; Mitiga possíveis erros humanos na adição/remoção de discos do ASM;

Disponibilidade Única solução de Alta Disponibilidade, ficando o ambiente homogêneo; Possibilita a utilização de múltiplos tipos de Storage; Com o Vplex e possível trocar o storage online e de forma transparente para o banco de dados; Havendo a necessidade de ampliação do ambiente, essa atividade pode ocorrer de forma

transparente; O Witness do Vplex monitora o hardware, utilização de IO e falhas de comunicação, evitando

eficientemente o risco de split brain;

Desempenho Com o Vplex temos todos os benefícios do cache do hardware,

otimizando as operações do banco de dados bem como a repliação; Utilizando o vplex o Trafego do servidor de banco de dados fica

isolado em seu próprio Site; Com o Vplex o ambiente ficara com um numero menor de discos

melhorando ate o tempo de boot do servidor; Elimina a necessidade de replicação por parte do banco de

dados/ASM;
