  • Page 155 You can run rebuild and verification operations without taking an array offline. These functions are performed as background tasks on the SmartRAID V controller and are transparent to the host operating system. However, the controller interleaves I/O from the operating system with I/O from the background task and this can affect system performance.
  • Page 156 SmartRAID V controllers keep a cumulative record of I/O operations in cache RAM for use in analyzing the efficiency of the storage subsystem. You can view this data by selecting in the Information window for any, controller, drive or array. By analyzing these statistics, the array configuration, cache and stripe size can be optimized for your particular system configuration.

  • Page 158 In RAID 1 arrays, can be up to twice the value of because each sector written from the host results in a write to each mirrored disk. In RAID 5 arrays, each write from the host can generate up to two disk reads and two disk writes. If the controller has cache memory, this can result in the actual number of sectors read from or written to disk being reported as less than this value.
  • Page 159 If cache hits are low, adding more cache RAM can also increase the hit count. Systems with a large number of disk writes also derive significant performance benefits from the controller cache. For RAID 0 and RAID 5 arrays, the default stripe size is set for optimal performance in most environments.

  • Page 174 The total amount of cache space supported by a SmartRAID V controller is fixed. Some of this total cache space is used when physical memory modules are installed on the controller to be used for standard cache.
  • Page 175 When cache RAM is added to a SmartRAID V controller, the operating system cache buffers must still be flushed. However, the controller receives and caches the flushed data in a fraction of the time required to actually write to a disk.
  • Page 176 1 second instead of 11 seconds. The SmartRAID V controller can then flush its cache to disk in elevator-sorted order using its separate I/O bus, concurrently with other system activity.
  • Page 177 I/O for the host system. This section describes the methods and rules used by SmartRAID V controllers to cache data for host I/O operations. Write-back is a method of postponing data to be written to a peripheral device, such as a disk drive, by temporarily saving the data in a cache.
  • Page 178 SmartRAID V controllers use virtual cache to track the patterns of data access for the most recently accessed disk data without actually caching that data.
  • Page 179 7-11 Theory of Operation The SmartRAID V pre-fetch algorithm analyses disk access patterns to detect whether the host is reading data that it previously read. By using records stored in virtual cache, the caching algorithm determines the boundaries of the contiguous block of previously read data surrounding the current host read request, then reads that data block into cache.
  • Page 180 Most operating systems that have caching capability can automatically manage the size of their disk cache. The SmartRAID V cache is used for predictive reads, elevator sorted write-backs and as temporary storage during RAID 5 parity calculations. Increasing the size of the cache makes these features more efficient. More cache RAM allows the controller to hold and elevator-sort more records, resulting in closer spacing between consecutive write-back segments.
  • Page 181 7-13 Theory of Operation The basic idea of RAID (Redundant Array of Independent Disks) is to combine multiple inexpensive disk drives into an array of disk drives to obtain performance, capacity and reliability that exceeds that of a single large drive. The array of drives appears to the host computer as a single logical drive.
  • Page 182 7-14 Theory of Operation STRIPING DISK DRIVES Disk 1 Disk 2 Disk 3 Disk 4 Data stripes from each drive are interleaved to create one logical drive. By striping the drives in the array with stripes large enough so that each record falls entirely within one stripe, most records can be evenly distributed across all drives.
  • Page 183 ECC information. Because all disk drives today embed ECC information within each sector, RAID 2 offers no significant advantages over other RAID architectures and is not supported by SmartRAID V. RAID 2 Parallel Array with ECC Each write operation spans all drives.
  • Page 184 Synchronized-spindle drives are required for RAID 3 arrays in order to avoid performance degradation with short records. Because RAID 5 arrays with small stripes can yield similar performance to RAID 3 arrays, RAID 3 is not supported by SmartRAID V. RAID 3 Parallel Array with Parity Read and write operations span all drives.
  • Page 185 7-17 Theory of Operation RAID 5, sometimes called a Rotating Parity Array, avoids the write bottleneck caused by the single dedicated parity drive of RAID 4. Under RAID 5 parity information is distributed across all the drives. Since there is no dedicated parity drive, all drives contain data and read operations can be overlapped on every drive in the array.
  • Page 186 At least three drives are required for RAID 5 arrays. In addition to the standard RAID levels, SmartRAID V controllers can combine multiple hardware RAID arrays into a single array group or parity group. In a dual-level RAID configuration, the controller firmware stripes two or more hardware arrays into a single array.
  • Page 187 7-19 Theory of Operation RAID 5 offers improved storage efficiency over RAID 1 because only the parity information is stored, rather than a complete redundant copy of all data. The result is that three or more drives can be combined into a RAID 5 array, with the storage capacity of only one drive dedicated to store the parity information.
  • Page 188 SmartRAID V controllers maintain two lists for each RAID 5 array: a Bad Parity List, and a Bad Data List. These lists contain the physical block number of any parity or data block that could not be successfully written during normal write, rebuild or dynamic array expansion operations.
  • Page 189 A failed drive can be replaced in a RAID 1 or RAID 5 array by physically removing the drive and replacing it or by a designated Hot Spare. SmartRAID V controllers will rebuild the data for the failed drive onto the new drive or Hot Spare. This rebuild operation occurs online while normal host reads and writes are being processed by the array.
  • Page 190 O Messaging, which uses the full performance capability and function of the PCI bus. SmartRAID V controllers can communicate with any ASPI protocol device under Windows NT and Windows 95/98. ASPI support under MS-DOS is limited to CD-ROM drives only. MS-DOS support is provided by the I2ODDL.SYS and DPTCDROM.SYS driver files.
  • Page 191 Command overlapping is a technique that lets a controller receive and respond to multiple host requests before any particular request is completed. SmartRAID V controllers can receive additional commands before the previous command has finished executing. By allowing multiple outstanding commands, SmartRAID V controllers can optimize performance by overlapping commands for multiple devices, thereby keeping all devices busy as much as possible.

SmartRAID V Century controllers are configured by the host BIOS as multifunction PCI devices.
  • Page 194 These SCSI IDs can be any number from 0 – 7 or, for Wide SCSI devices, 0 – 15. The SmartRAID V controller ID is set by default to ID 7. In 8-bit SCSI systems, the device with ID 7 has the highest priority and ID 0 has the lowest priority when arbitrating for use of the SCSI bus.
  • Page 195 Theory of Operation A SCSI device may contain up to eight sub-devices or Logical Units, assigned Logical Unit Numbers (LUN) 0 – 7. SmartRAID V controllers support multiple LUNs. However, most devices other than bridge controllers consist of only one LUN and are accessed as LUN 0 by SmartRAID V controllers.
  • Page 196 It is also possible for a SCSI peripheral device to read or write less data than was requested by the host. If this occurs, SmartRAID V controllers will report the actual number of bytes transferred as less than the requested number of bytes.
  • Page 197 Do not attach High Voltage Differential devices to an Ultra2 bus. The SCSI-2 specification defines 8-bit, 16-bit and 32-bit bus widths. All SmartRAID V controllers use a 16-bit bus and support both 8-bit and 16-bit SCSI devices. SmartRAID V controllers are capable of handling a combination of SCSI devices with different transfer speeds, and both synchronous and asynchronous protocols on the same SCSI bus.
  • Page 198 7-30 Theory of Operation The original SCSI specification synchronous transfer rates of up to 5MHz. The SCSI-2 specification increased the maximum synchronous rate to 10MHz. Devices that support the faster 10MHz rate are called Fast SCSI devices. The SCSI-3 specification defines transfer rates up to 20MHz (Fast- 20/Ultra SCSI).
  • Page 199 7-31 Theory of Operation Beware of capacitance changes. As devices are added to a SCSI bus, capacitance is introduced to each signal from the connectors, receivers, and circuit board traces. The SCSI-3 working specification limits this capacitance to 25pF because added capacitance lowers the impedance of the cable near the device and adds delay.
