22 Virtualizzazione Storage: LeftHand Un cluster di storage nodes Ogni nodo contiene capacità (disk drive) e controller (cache, porte, CPU) L array è l insieme di nodi, da 2 a 30+ gestiti come un singolo sistema cluster I volumi sono distribuiti su tutti i nodi in un cluster Crescita Aggiungere nuovi nodi in ogni momento ed on-line: crescono capacità e performance Riallocazione automatica dei volumi Supporto di multipli tier con migrazione online Gestione Centralizzata Una console per tutti i LeftHand P4000 presenti anche in mulltipli siti local data center e uffici remoti P4000 fisiche e virtuali SAS Storage Node Server A CPU NICs Server B Disk Cache Hardware RAID SAN/iQ Storage Software Redundant Cooling Redundant power Server C Server D SATA Centralized Management Console

23 BC: una sfida complessa! o no? Problema Site/Rack 1 Site/Rack2 Single Cluster Array traditionali proteggono solo da guasti di componenti HW RAID Componenti ridondate Nessuna protezione da Guasti di sistema Room maintenance Data center outage Single Cluster HP LeftHand Multi-Site SAN Mantiene i dati online anche nel caso di: Problemi al sito Disastri naturali A F A B C B C D E D E F = or > 1 Gb Manutenzione del datacenter Single SAN stretched between two sites or racks

24 Storage: alcune importanti considerazioni Integrazioni VAAI Demandare le operazioni di clone, deploy, migrate direttamente allo storage Virtual array Volumi, non array Performance Flessibilità Space efficiency Thin provisioning Zero delete Zero detect Space reclamation Multi-Site cost-effective Network Raid Remote snapshot Integrazioni vcenter Datastore Provisioning Snapshot di volumi vmfs consistenti Multi-Tier Allocazione dinamica Migrazione a caldo 24
