3 Esigenze dei clienti Keeping up with data growth without adding cost or complexity Affordable Budgets aren t all flexible Scalability and Flexibility Growing your storage infrastructure almost always means increasing complexity of your storage architecture Unable to support business needs due to insufficient storage solution. Reliability and Highly available Unpredicted downtime and data loss Everyone s applications are critical Management IT Admin costs increasing due to complexity/obsolescence of infrastructure, interoperability within environment Usability Extensive interoperability testing and migration cycles Easy to use Not everyone is a storage specialist

4 Virtualizzazione e storage VIRTUALIZATION USE IS GROWING: 2006: 6% OF VOLUME SERVERS DEPLOYED IN VIRTUALIZED ENVIRONMENTS 2011: OVER 20% LIVE MIGRATION IS KEY FEATURE: 2006: USED ON 44% OF VIRTUALIZED PLATFORMS 2011: USED ON OVER 80%

6 Tipi di storage Tecnologia Protocollo Velocità Tipo di dati Utilizzo DAS SCSI, SAS 320 MB/s, 1.5 Gb/s blocchi storage locale NAS IP 100Mb/s, 1Gb/s file file sharing CAS IP archivi archiviazione SAN Fibra FC 4 Gb/s blocchi storage condiviso SAN Rame FCIP, iscsi 100Mb/s, 1Gb/s blocchi storage condiviso DAS (Direct Attached Storage) NAS (Network Attached Storage ) CAS (Content Addressable Storage) SAN (Storage Area Network) ESN (Enterprise Storage Network) iban (InfiniBand Area Network)

7 Network-Attached Storage (NAS) Evoluzione dei fileserver Utilizzano protocolli di condivisione file CIFS/SMB NFS FTP Basati su sistemi embedded Custom Windows Storage Linux Funzioni RAID interne Affidabilità e disponibilità?

8 Storage Area Network (SAN) Rete dedicata ad alta velocità per collegare host con dischi e/o librerie di nastri Componente tipica dell Enterprise Storage Tipi di protocolli adottati Fibre Channel networking con SCSI command set iscsi (2003) con SCSI command set over TCP/IP ATA-over-Ethernet (AOE) protocol Lato server (host) Fibre Channel Host Bus Adapter (HBA) Accesso tramite Logical Unit Number (LUN) Differenze dai sistemi NAS

9 SAN FC o iscsi Fibre channel e iscsi entrambi sono dei protocolli per reti SAN entrambi trasportano instruzioni SCSI entrambi permettono la connessione di dischi esterni e condivisi Ma non hanno lo stesso costo non hanno le stesse prestazioni e la stessa affidabilità non hanno la stessa flessibilità Quale scegliere?

10 Fiber Channel (1) Fibre Channel è una tecnologia per reti dati, usata principalmente per implementazioni di SAN in fibra Iniziò per un utilizzo principalmente nel campo dei supercomputer, ma è diventato il tipo di connessione standard per le SAN nell'enterprise storage Il Fibre Channel Protocol (FCP) è il protocollo di interfaccia dello SCSI sul Fibre Channel Nonostante il nome, il segnale Fibre Channel può viaggiare sia su cavi in rame UTP che in fibra ottica Attualmente la velocità tipica è di 4 Gb/s Esistono già i primi prodotti a 8 Gb/s

11 Fibre Channel (2) Rete Fabric Redundant Fibre Channel Switches Dell EMC SAN VMware ESX Server on Dell PowerEdge Alternative DAS?

12 iscsi (1) iscsi sfrutta l infrastruttura IP, tipicamente conosciuta e diffusa, utilizzando il protocollo TCP per muovere dati fra le applicazioni e risorse storage si basa su un modello Target/Initiator può utilizzare NIC Ethernet standard oppure apposite HBA Permette al protocollo SCSI di essere trasportato su LAN Ethernet e su WAN IP Possibili soluzioni per la sicurezza 802.1x, CHAP e IPSec verificare quale è supportata!

13 iscsi (2) iscsi initiator File system Disk driver SCSI SCSI MP File system Disk driver SCSI iscsi MP TCP/IP Ethernet iscsi target iscsi SCSI TCP/IP Ethernet Ethernet Direct attached block storage using SCSI/SAS Remote block storage using iscsi Ethernet header IP header TCP iscsi header SCSI payload data CRC
