www.3ware.com 1 About this CLI Guide 3war e Serial A T A Contr oller CLI Guide provides instructio ns for configuring and maintaining your 3ware controller using 3ware’ s command line interface (CLI). There are often multiple ways to acc omplish the same configuration and maintenance tasks for your 3ware cont roller .
2 3ware Serial ATA RAID Controller CLI Guide 1 Intr oduction to the 3w ar e Command Line Interf ace The 3ware SA T A RAID Controller Command Line Interface (CLI) for Linux, W indows, and FreeBSD is provided to manage 7000, 8000, and 9000-series 3ware A T A and Serial A T A RAID controllers.
Supported Operating Systems www.3ware.com 3 Y ou can use the CLI to view unit status and version information and perform maintenance functions su ch as adding or removing drives. 3ware CLI also includes advanc ed features for creating and deleting RAID units online.

Understanding RAID Levels an d Co nc ep ts www.3ware.com 9 Under standing RAID Le v els and Concepts 3ware RAID controllers u se RAID (Redundant Array of In expensive Disks) to increase your storage system’ s pe rformance and provide fault tolerance (protection against data loss).
Chapter 1. Intr od uc tio n to the 3w ar e Command Line Interfa ce 10 3ware Serial ATA RAID Controller CLI Guide • Array Roaming. The process of removing a unit from a controller and putting it back later , either on the sa me controller , or a dif ferent one, and having it recognized as a un it.
Understanding RAID Levels an d Co nc ep ts www.3ware.com 11 RAID 1 RAID 1 provides fault tolerance and a speed advantag e over non-RAID disks. RAID 1 is also known as a mirrored array . Mirroring is done on pairs of drives. Mirrored disk arrays write the sam e data to two dif ferent drives using RAID 1 algorithms (see Figure ?).

Understanding RAID Levels an d Co nc ep ts www.3ware.com 17 Using Drive Cap acity Efficiently T o make the most efficient use of drive capacity , it is advisable to use drives of the same capacity . This is because th e capacity of each drive is limited to the capacity of the sma llest drive in the unit.
Chapter 1. Intr od uc tio n to the 3w ar e Command Line Interfa ce 18 3ware Serial ATA RAID Controller CLI Guide Through drive coercion, the capac ity us ed for each drive is rounded down so that drives from dif fering manufacturers ar e more likely to be able to be used as spares for each other .

Un punto importante, dopo l’acquisto del dispositivo (o anche prima di acquisto) è quello di leggere il manuale. Dobbiamo farlo per diversi motivi semplici:
Se non hai ancora comprato il AMCC 9500S è un buon momento per familiarizzare con i dati di base del prodotto. Prime consultare le pagine iniziali del manuale d’uso, che si trova al di sopra. Dovresti trovare lì i dati tecnici più importanti del AMCC 9500S - in questo modo è possibile verificare se l’apparecchio soddisfa le tue esigenze. Esplorando le pagine segenti del manuali d’uso AMCC 9500S imparerai tutte le caratteristiche del prodotto e le informazioni sul suo funzionamento. Le informazioni sul AMCC 9500S ti aiuteranno sicuramente a prendere una decisione relativa all’acquisto.
In una situazione in cui hai già il AMCC 9500S, ma non hai ancora letto il manuale d’uso, dovresti farlo per le ragioni sopra descritte. Saprai quindi se hai correttamente usato le funzioni disponibili, e se hai commesso errori che possono ridurre la durata di vita del AMCC 9500S.
Tuttavia, uno dei ruoli più importanti per l’utente svolti dal manuale d’uso è quello di aiutare a risolvere i problemi con il AMCC 9500S. Quasi sempre, ci troverai Troubleshooting, cioè i guasti più frequenti e malfunzionamenti del dispositivo AMCC 9500S insieme con le istruzioni su come risolverli. Anche se non si riesci a risolvere il problema, il manuale d’uso ti mostrerà il percorso di ulteriori procedimenti – il contatto con il centro servizio clienti o il servizio più vicino.
