  • Page 58: Chapter 5- Understanding Raid

    5-Understanding RAID Chapter 5- Understanding RAID The MaxNAS R8 controller subsystem is a high-performance SATA drive bus disk array controller. When properly configured, the RAID subsystem can provide non-stop service with a high degree of fault tolerance through the use of RAID technology and advanced array management features. The RAID subsystem can be configured to RAID levels 0, 1 (0+1), 5, and 6.
  • Page 59 5-Understanding RAID RAID 1 (Disk Mirroring) RAID 1, also known as “disk mirroring”, distributes duplicate data simultaneously to pairs of disk drives. Pros: RAID 1 offers extremely high data reliability as all the data is redundant. If one drive fails, all data (and software applications) are preserved on the other drive. Read performance may be enhanced as the array controller can access both members of a mirrored pair in parallel. Cons: RAID 1 volume requires double the raw data storage capacity Performance penalty when compared to writing to a single disk. RAID 10 RAID 10 is a combination of RAID 0 and RAID 1, combing striping with disk mirroring.
  • Page 60 5-Understanding RAID RAID 6 Also known as dual parity, RAID 6 is similar to RAID 5, but offers double the fault tolerance by performing two parity computations on overlapping subsets of the data. RAID 6 offers fault tolerance greater that RAID 1 or RAID 5 but only consumes the capacity of 2 disk drives for distributed parity data.

  • Page 71 E-Glossary Disk Array A Disk Array is a logical disk comprised of multiple physical hard disks. The number of hard disks in an disk array is dictated by the type of the array and the number of spares that may be assigned to it. Furthermore, whether a disk array can be built using part of the space on a disk (as opposed to being forced to use the whole disk) depends upon the implementation.
  • Page 72 E-Glossary by any RAID array as a backup. In the event a hard disk in a RAID array fails, this backup is automatically mobilized by the RAID controller to step in place of the failed hard disk. The data in the failed hard disk is “reconstructed” and written into the new hard disk. In the case of a RAID 1, data is reconstructed by simply copying the contents of the surviving disk into the spare.

  • Page 74 E-Glossary of the disks fails, its contents can be retrieved from the duplicate disk. Furthermore, a RAID 1 array can also improve the throughput of read operations by allowing separate reads to be performed concurrently on the two disks. RAID 5 A RAID 5 array is similar to a RAID 4 array in that, it utilizes a striped set of three or more disks with parity of the strips (or chunks) comprising a stripe being assigned to the disks in the set in a round robin fashion.
  • Page 75 E-Glossary Secondary Storage Mass storage devices such as hard disks, magneto-optical disks, floppy disks and tapes are frequently referred to as secondary storage. Secure Sockets Layer (SSL) is a cryptographic protocol which provide secure communications on the Internet. SSL provides endpoint authentication and communications privacy over the Internet using cryptography.
  • Page 76 E-Glossary the favoured replication model is the HUB and SPOKE, and thus the WINS design is not central but distributed, each WINS server holds a full copy of every other related WINS system records. There is no hierarchy in WINS (unlike DNS) but like DNS its database can be queried for the address to contact rather than broadcasting a request for which address to contact.
