    Chapter 2. RAID Array Controller There are two configurations for redundant pairs of controllers: Active/Active Failover mode and Active/Passive Failover mode. In Active/Active Failover, each controller in the redundant pair has one active SCSI host port and one pas- sive SCSI host port. Redundancy Groups (Virtual LUNS) can be mapped only to one active host port and are not accessible from the passive port or the other controller (i.e.

  • Page 37: Logical Units Created From Storagesets, Partitions, And Disk Drives

    RAID Array 3000 Controller Shelf From the storage shelf’s perspective, the controller receives the I/O requests from the host and directs them to the devices. Since the controller processes all the I/O requests, it eliminates the host-based processing that is typically associated with reading and writing data to multiple storage devices.

RAID Array Controller Performance Enhancements The controller employs a number of techniques to achieve as much performance as possible from its design. 2.5.1 Custom Components To increase performance and reliability, the controller’s core functions have been encapsulated in four custom ASIC (Application Specific Integrated Circuits) components as follows: XOR ASIC: Used in the Exclusive -Or parity calculations employed by RAID levels 4 and 5.

  • Page 41: Raid Levels Supported

    RAID Array 3000 Controller Shelf 2.5.2.1 Write-Back Caching When the host sends data to be written to a redundancy group the controller stores the data in its cache and immediately reports to the host it has completed the write. The controller eventually writes the data to the disk drives when the write can be done most efficiently, or when the controller must flush the cache to make room for other data or to prepare for a shutdown.

    Chapter 2. RAID Array Controller There are some restrictions you must adhere to when creating a RAID set using the RAID 3000 shelf. The minimum and maximum number of drives required to support each RAID level is listed in Table 2–3. Table 2–3 Shelf RAID Set Restrictions RAID Level Min.

    Chapter 2. RAID Array Controller 2.6.2 RAID 1 RAID 1 (also known as mirroring or shadowing) takes data sent by the host and duplicates it on all the drives in an array. The result is a high degree of data availability, since you can lose all but one drive in the array and still have full access to your data.

  • Page 46: Raid 4

    Chapter 2. RAID Array Controller 2.6.4 RAID 4 RAID 4 (Figure 2–8) breaks up host data into chunks, calculates parity by per- forming an exclusive-or on the chunks, and then writes the chunks to all but one drive in the array and the parity data to the last drive. When the host requests data from the disk drives, the controller retrieves the chunks containing the ad- dressed data, reconstitutes the data from the chunks, and passes the data to the host.

  • Page 47: Raid 5

    RAID Array 3000 Controller Shelf In the event of a single drive failure, a RAID 4 array will continue to operate in degraded mode. If the failed drive is a data drive, writes will continue as normal, except no data will be written to the failed drive. Reads will reconstruct the data on the failed drive by performing an exclusive-or operation on the remaining data in the stripe and the parity for that stripe.

  • Page 49: Jbod

    RAID Array 3000 Controller Shelf While RAID 5 is ideally suited for applications with many, small I/O operations, there is no reason why it cannot function equally well for applications with large, sequential I/O operations. This makes RAID 5 an excellent all-purpose RAID level.

  • Page 50: Initialization

    Chapter 2. RAID Array Controller When one controller fails, the survivor will process all I/O requests until the failed controller is repaired and powered on.

    RAID Array 3000 Controller Shelf Environmental The controller incorporates a set of on board sensors to detect abnormal operat- ing conditions that may affect data safety. 2.9.1 Backup Power Management The controller must be connected to the Uninterruptable power supply (UPS) to prevent the subsystem cache from being corrupted during unexpected losses of power.
