4. RAID 5 2 3 Data Parity The controller can generate parity for the ability to protect and rebuild data Parity protects stored information without requiring data mirroring When data is protected by parity it is still available if a drive fails Parity protected data is reconstructed using the parity formula You can remove and replace a failed disk known as hot swapping and the controller then rebuilds the data using the information on the remaining drives 5 3 RAID Levels The ExaSAN RAID system supports several RAID levels and configurations Each level has a different architecture and provides varying degrees of performance and fault tolerance Each level has characteristics to achieve maximum performance or redundancy depending on the data environment 5 3 1 RAID 0 Striping RAID level 0 striping only is the fastest and most efficient array type but offer no fault tolerance Any drive failure destroys the data in the array 9 3 2 RAID 1 Mirroring RAID level 1 mirroring has been used for Metadata LUN because of its simplicity and high levels of reliability and availability Mirroring uses two drives each drive stores identical data RAID 1 provides very high data reliability and improved performance for read intensive applications but this level has a high capacity cost because it retains a full copy of your data on each drive in mirror set In a RAID 1 configuration the capacity of the smallest drive is t

8. 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 in that logical unit 5 2 Data Storage Methods The controller stores and retrieves data on a RAID system using techniques such as data striping data mirroring and data parity 5 2 1 Data Striping Multiple hard disk drives in a RAID group referred to as a set or array are divided partitioned into stripes The controller spreads stripes across the disks in alternating sections on each drive In data intensive environments such as digital video editing performance is optimized by writing data across small stripes so that each record spans all drives This method ensures that access to large records is very fast because data is transferred in parallel across multiple drives 5 2 2 Data Mirroring To mirror data the RAID controller duplicates all data on two different disks One disk is the primary the other is the mirrored disk The primary and mirrored disks are synchronized that is anything written to one disk is also written to the other Mirrored data is very secure because if one disk fails the data is available from the other disk e Pe storage a swihes User Guide 5 1
