User Guide 5 RAID 5 RAID Overview c paestorageaswiches User Guide RAID 5 RAID Overview This chapter gives an overview of RAID storage system within the context of recommended setting of ExaSAN based SAN environment to provide fast shared storage to client computers 5 1 How RAID Works RAID or Redundant Array of Independent Disks is a data storage technology that spreads data across multiple drives This technology provides several benefits over a single large hard disk including e Data redundancy for protection and availability e Higher performance as a result of reading or writing on several drives simultaneously e Scalability for expansion of storage The ExaSAN family RAID systems use a hardware controller which manages up to 48 HDDs By segmenting and writing or reading data on multiple drives simultaneously the RAID controller achieves fast and highly efficient storage and access The way the controller stores and retrieves data on the RAID system is determined by the RAID level and storage method you choose For ExaSAN applications the recommended setting is mainly RAID 1 and RAID 5 which will be discussed in details later in this chapter Once you have defined a group of drive modules as a RAID set the controller groups those drives into logical disks On the ExaSAN RAID system each logical disk appears to the client system as one Logical Unit LUN regardless of the number of actual drives i
