When the Full Bus switch is set to on, BCC A, in the top slot, accesses the disks in all ten slots. When the Full Bus switch is off, BCC A accesses disks in the even-numbered slots and BCC B accesses disks in the odd-numbered slots.
  • Page 27 Each BCC provides two LVD SCSI ports (B in Figure 5) for connection to the controller enclosure.

  • Page 29: Power Supplies

    Power Supplies Redundant, hot-swappable 450-watt power supplies convert wide-ranging AC voltage from an external main to stable DC output and deliver it to the backplane. Each power supply has two internal blowers, an AC receptacle (A in Figure 7), a cam handle (B) with locking screw, and an LED (C).
  • Page 30 Power supplies share the load reciprocally; that is, each supply automatically increases its output to compensate for reduced output from the other. If one power supply fails, the other delivers the entire load. Internal circuitry triggers a fault when a power supply fan or other power supply part fails. If a power supply failure occurs, the amber fault LED will go on.
  • Page 31: Array Controller Enclosure Components

    Array Controller Enclosure Components The array controller enclosure, like the disk enclosure, consists of several modules that can be easily replaced, plus several additional internal assemblies. See Figure 8. Together, these removable modules and internal assemblies make up the field replaceable units (FRUs).

    Figure 10 Controller Enclosure Rear View Front Cover The controller enclosure has a removable front cover which contains slots for viewing the main operating LEDs. The cover also contains grills that aid air circulation. The controller modules, controller fan, and battery backup unit are located behind this cover. This cover must be removed to gain access to these modules, and also, to observe the controller status and BBU LEDs.
  • Page 35: Controller Modules

    Controller Modules The controller enclosure contains two controller modules. See Figure 11. These modules provide the main data and status processing for the Disk Array FC60. The controller modules slide into two controller slots (A and B) and plug directly into the backplane. Two handles lock the modules in place.
  • Page 36 Each controller module has ten LEDs. See Figure 12. One LED identifies the controller module’s power status. A second LED indicates when a fault is detected. The remaining eight LEDs provide detailed fault condition status. The most significant LED, the heartbeat, flashes approximately every two seconds beginning 15 seconds after power-on.
  • Page 37: Controller Fan Modules

    Controller Memory Modules Each controller module contains SIMM and DIMM memory modules. Two 16-Mbyte SIMMs (32 Mbytes total) store controller program and other data required for operation. The controller includes two DIMMs, which provide 256 Mbytes of cache. Cache memory serves as temporary data storage during read and write operations, improving I/O performance.

  • Page 39: Power Supply Modules

    Power Supply Modules Two separate power supplies provide electrical power to the internal components by converting incoming AC voltage to DC voltage. Both power supplies are housed in removable power supply modules that slide into two slots in the back of the controller and plug directly into the power interface board.
  • Page 40: Power Supply Fan Module

    Each power supply is equipped with a power switch to disconnect power to the supply. Turning off both switches turns off power to the controller. This should not be performed unless I/O activity to the disk array has been stopped, and the write cache has been flushed as indicated by the Fast Write Cache LED being off.

  • Page 42: Battery Backup Unit

    Battery Backup Unit The controller enclosure contains one removable battery backup unit (BBU) that houses two rechargeable internal batteries (A and B) and a battery charger board. The BBU plugs into the front of the controller enclosure where it provides backup power to the controller’s cache memory during a power outage.
  • Page 43 The BBU contains four LEDs that identify the condition of the battery. Internally, the BBU consists of two batteries or banks, identified as bank “A” and bank “B.” During normal operation both of the Full Charge LEDs (Full Charge-A and Full Charge-B) are on and the two amber Fault LEDs are off.

  • Page 45: Disk Array High Availability Features

    Disk Array High Availability Features High availability systems are designed to provide uninterrupted operation should a hardware failure occur. Disk arrays contribute to high availability by ensuring that user data remains accessible even when a disk or other component within the Disk Array FC60 fails.
  • Page 46: Data Parity

    The disk array uses hardware mirroring, in which the disk array automatically synchronizes the two disk images, without user or operating system involvement. This is unlike the software mirroring, in which the host operating system software (for example, LVM) synchronizes the disk images. Disk mirroring is used by RAID 1 and RAID 0/1 volume groups.
  • Page 47: Data Striping

    Data Data Data Data Parity If this bit is now written as 1... This bit will also be changed to a 1 so the total still equals 0. Figure 17 Calculating Data Parity Data Striping Data striping, which is used on RAID 0, 0/1, 3 and 5 volume groups, is the performance- enhancing technique of reading and writing data to uniformly sized segments on all disks in a volume group simultaneously.
  • Page 48: Raid Levels

    using a 5-disk RAID 5 volume group, a stripe segment size of 32 blocks (16 B) would ensure that an entire I/O would fit on a single stripe (16 B on each of the four data disks). The total stripe size is the number of disks in a volume group multiplied by the stripe segment size.
  • Page 49 Figure 18 Volume Group RAID 0 RAID 1 RAID 1 uses mirroring to achieve data redundancy. RAID 1 provides high availability and good performance, but at the cost of storage efficiency. Because all data is mirrored, a RAID 1 volume group has a storage efficiency of 50%. A RAID 1 volume group consists of exactly two disks configured as a mirrored pair.
  • Page 50 Figure 19 shows the distribution of data on a RAID 1 volume group. Note that all data on the data disk is replicated on the disk mirror. Figure 19 Volume Group RAID 1 RAID 0/1 RAID 0/1 uses mirroring to achieve data redundancy and disk striping to enhance performance.
  • Page 51 of the pair. If both disks fail or become inaccessible simultaneously, the data on the volume group becomes inaccessible. Figure 20 illustrates the distribution of data in a four-module RAID 0/1 volume group. The disk block addresses in the stripe proceed sequentially from the first pair of mirrored disks (disks 1 and 2) to the second pair of mirrored disks (disks 3 and 4), then again from the first mirrored disks, and so on.
  • Page 52 disk. The rebuilt volume group contains an exact replica of the information it would have contained had the disk not failed. Until a failed disk is replaced (or a rebuild on a global hot spare is completed), the volume group operates in degraded mode. The volume group must now use the data and parity on the remaining disks to recreate the content of the failed disk, which reduces performance.
  • Page 53 RAID 3 works well for single-task applications using large block I/Os. It is not a good choice for transaction processing systems because the dedicated parity drive is a performance bottleneck. Whenever data is written to a data disk, a write must also be performed to the parity drive.
  • Page 54 Figure 22 Volume Group RAID 5 With its individual access characteristics, RAID 5 provides high read throughput for small block-size requests (2 B to 8 B) by allowing simultaneous read operations from each disk in the volume group. During a write I/O, the disk array must perform four individual operations, which affects the write performance of a RAID 5 volume group.
  • Page 55: Raid Level Comparisons

    RAID Level Comparisons To help you decide which RAID level to select for a volume group, the following tables compare the characteristics for the supported RAID levels. Where appropriate, the relative strengths and weakness of each RAID level are noted. Table 1 RAID Level Comparison: Data Redundancy Characteristics Handle multiple disk...
  • Page 56 Table 3 RAID Level Comparison: Relative Performance Compared to an Individual Disk* Volume Group Relative Read Performance Relative Write Performance Configuration for Large Sequential Access for Large Sequential Access RAID 0 The read and write performance of a RAID 0 volume group increases as the multiple of the number of disks in the volume group.

In general, the greater the number of mirrored pairs, the greater the increase in performance. RAID 1 –...
  • Page 58 Table 5 RAID Level Comparison: Application and I/O Pattern Performance Characteristics RAID level Application and I/O Pattern Performance RAID 0 RAID 0 is a good choice in the following situations: – Data protection is not critical. RAID 0 provides no data redundancy for protection against disk failure.
  • Page 59: Global Hot Spare Disks

    Global Hot Spare Disks A global hot spare disk is reserved for use as a replacement disk if a data disk fails. Their role is to provide hardware redundancy for the disks in the array. To achieve the highest level of availability, it is recommended that one global hot spare disk be created for each channel.
  • Page 60 Settings that give a higher priority to the rebuild process will cause the rebuild to complete sooner, but at the expense of I/O performance. Lower rebuild priority settings favors host I/Os, which will maintain I/O performance but delay the completion of the rebuild. The rebuild priority settings selected reflect the importance of performance versus data availability.
  • Page 61 Data and parity from the remaining disks are used to rebuild the contents of disk 3 on the hot spare disk. The information on the hot spare is copied to the replaced disk, and the hot spare is again available to protect against another disk failure.
  • Page 62: Capacity Management Features

    Capacity Management Features The disk array uses a number of features to manage its disk capacity efficiently. Volume groups allow you to partition the total disk capacity into smaller, functional entities. Caching improves disk array performance by using controller RAM to temporarily store data during I/Os.
  • Page 63: Disk Array Caching

    Disk Array Caching Disk caching is the technique of storing data temporarily in RAM while performing I/Os to the disk array. Using RAM as a temporary storage medium can significantly improve the response time for many types of I/O operations. From the host’s perspective the data transfer is complete, even if the disk media was not involved in the transaction.
  • Page 64: Dynamic Capacity Expansion

    In the event of an unexpected disk array shutdown or loss of power, the BBU provides power to cache memory to maintain the cache for 120 hours (5 days). Dynamic Capacity Expansion If slots are available in the disk enclosures, you can increase the capacity of the disk array without disrupting operation.

  • Page 68: Raid, Volume Groups, And Global Hot Spares

    Ultra2 SCSI Channel Operations The disk array controller enclosure provides six Ultra2 SCSI channel connections for up to six disk enclosures. Six separate channels provide several options. One is that the disk arrays can be added incrementally as storage capacity is needed. It also allows six disk enclosures to be connected, as mentioned above, to provide a high volume storage capacity array.

  • Page 70 disk enclosure). This configuration also offers full sequential performance and is more economical to implement. To scale up sequential transfer performance from the host, configure additional disk arrays. This will increase the total I/O bandwidth available to the server. Performance can also be measured by the number of I/O operations per second a system can perform.
  • Page 71: Storage Capacity

    Storage Capacity For configurations where maximum storage capacity at minimum cost is a requirement, consider configuring the disk array in RAID 5 (using the maximum number of data drives per parity drives) and only supplying one or two hot spare drives per disk array. Also, purchase the lowest cost/Mbyte drive available (typically the largest capacity drives available at the time of purchase).

    This section presents recommended configurations for disk arrays using one to six disk enclosures. Configurations are provided for achieving high availability/high performance, and maximum capacity. The configuration recommended by Hewlett-Packard is the high availability/ high performance configuration. The configurations identify the number of disk enclosures, cable connections, disk enclosure bus modes, RAID level, and volume groupstructure.

    • Global hot spares - although none of the configurations use global hot spares, their use is recommended to achieve maximum protection against disk failure. For more information, see "Global Hot Spare Disks" on page • Split bus operation - With three or fewer disk enclosures, increased performance can be achieved by operating the disk enclosures in split bus mode, which increases the number of SCSI busses available for data transfer.

  • Page 336 DIMM Figure 113 Controller Module DIMM Replacement Installing the Controller Module When a new controller module is installed, the resident controller checks the Note firmware version of the new controller. If the versions do not match, the resident controller downloads its firmware to the new controller module. This procedure, called Auto Code Synchronization (ACS), ensures that both controllers are operating with the same version of firmware.
  • Page 337 If Auto Code Synchronization (ACS) occurs when the new controller module AUTION is installed. DO NOT turn array power off, reset the controller modules, or reseat the controller module for approximately 15 minutes after initial insertion. Performing any of these actions during ACS may damage the controller and it will have to be replaced.
  • Page 338: Scsi Cables

    the controller module LEDs do indicate a normal operating state, refer to chapter 6, for troubleshooting information. Figure 114 Identifying the ACS Process SCSI Cables Replacing SCSI cables requires that the disk enclosure be shut down. Shutting down the enclosure will degrade the performance of the array during the replacement. When the replacement is completed and the disk enclosure is powered up, the array will perform a rebuild (since I/O has occurred to the array while the disk enclosure was powered off).
