Les moteurs DB2 tournent sur n noeuds

– Ils coopèrent entre eux pour délivrer un

accès cohérent

Data sharing architecture– Accès partagés à la base de données

– Chaque noeud écrit ses propres log sur des

disques partagés

PowerHA PureScale technology:

– Global locking & buffer management

– Synchronous duplexing assurant la haute disponibilité

Low latency, high speed interconnect

– RDMA-capable interconnects (Infiniband)

« Clients connect anywhere,… see

single database »– Les clients peuvent se connecter sur chaque noeuds

– Load Balancing automatique

Cluster services intégré

– Détection de la perte ou de l'ajout d'un membre

– Recovery automation,En partenariat avec STG & Tivoli

General Parallel File System( GPFS)

IBM PowerVM Virtualization Features• Processor

– Shared or dedicated LPARs– Capped or uncapped LPARs– Multiple shared processor pools– Dynamic LPAR operations

(add/remove)– Shared dedicated LPARs

• I/O – Shared and/or dedicated I/O– Virtual Ethernet, virtual SCSI– Dynamic LPAR operations

(add/remove)– Integrated Virtual Ethernet– Virtual FC (N_Port ID Virtualization)– Virtual Tape Support

• Memory– Dedicated memory– Active Memory Sharing– Dynamic LPAR operations

(add/remove)– Active Memory Expansion (AIX

6.1)

• Other– Integrated Virtualization Manager– Live LPAR mobility– Workload partitions (AIX 6.1)– Workload partition mobility (AIX 6.1)– Lx86 for Linux applications (Linux)

N_Port ID Virtualization (Virtual FC)

Page 8: Maquette DB2 PureScale - IBM · PDF fileMaquette DB2 PureScale ... Server Workload Partition Web NFS or SAN NetworkNFS or SAN Network ... VIO Server – AIX V5.3, AIX 6, AIX7

N_Port ID Virtualization Simplifies Disk Management

• N_Port ID Virtualization

– Multiple Virtual World Wide Port Names per FC port – PCIe 8 Gb adapter

– LPARs have direct visibility on SAN (Zoning/Masking)

– I/O Virtualization configuration effort is reduced

N_Port ID Virtualization• N_Port ID Virtualization

– Virtualizes FC adapters

– Virtual WWPNs are attributes of the client virtual FC adapters not physical adapters

– 64 WWPNs per FC port (128 per dual port HBA)

• Customer Value– Can use existing storage management tools

and techniques

– Allows common SAN managers, copy services, backup/restore, zoning, tape libraries, etc

– Transparent use of storage functions such as SCSI-2 reserve/release and SCSI3 persistent reserve

– Load balancing across VIOS

– Allows mobility without manual management intervention
