This is good for small databases or other applications that require small capacity but complete data redundancy NOTICE Lost data on an Integrated Striping virtual disk cannot be recovered in the event of a physical disk failure RAID Terminology Integrated Striping Integrated Striping RAID 0 allows you to write data across multiple physical disks instead of just one physical disk Integrated Striping involves partitioning each physical disk storage space into 64 KB stripes These stripes are interleaved in a repeated sequential manner The part of the stripe on a single physical disk is called a stripe element For example in a four disk system using only Integrated Striping segment is written to disk 1 segment 2 is written to disk 2 and so on Integrated Striping enhances performance because multiple physical disks are accessed simultaneously but Integrated Striping does not provide data redundancy Figure 1 2 shows an example of Integrated Striping Figure 1 2 Example of Integrated Striping RAID 0 Stripe element 1 Stripe element 2 Stripe element 3 Stripe element 4 Stripe element 5 Stripe element 6 Stripe element 7 Stripe element 8 Stripe element 9 Stripe element 10 Stripe element 11 Stripe element 12 Overview Integrated Mirroring With Integrated Mirroring RAID 1 data written to one disk is simultaneously written to another disk If one disk fails the contents of the other disk can be used to run the system
25. and rebuild the failed physical disk The primary advantage of Integrated Mirroring is that it provides 100 percent data redundancy Because the contents of the disk are completely written to a second disk it does not matter if one of the disks fails Both disks contain the same data at all times Either physical disk can act as the operational physical disk Ka NOTE Mirrored physical disks improve read performance by read load balance Figure 1 3 Example of Integrated Mirroring RAID 1 Stripe element 1 Stripe element 1 Duplicated Stripe element 2 Stripe element 2 Duplicated Stripe element 3 Stripe element 3 Duplicated Stripe element 4 Stripe element 4 Duplicated Overview 11 12 Overview SAS 6 iR Features This section provides the specifications of Dell Serial Attached SCSI SAS 6 iR controller The following table compares the specifications of the SAS 6 iR Adapter and SAS 6 iR Integrated Table 2 1 Specifications of SAS 6 iR Specification SAS 6 iR Adapter SAS 6 iR Integrated SAS technology Yes Yes Support for x4 x8 or x16 PCI Yes Yes Express Host Interface Form Factor Standard Height Half Length PCI Adapter System dependent I O controller IOC LSI SAS 1068e LSI SAS 1068e Core Speed 255 MHz Core Speed 255 MHz Operating voltage requirements 12V 3 3V 3 3Vaux 12V 3 3V 3 3Vaux Communication to the system PCI E lanes System dependent Commu

60. ysical link in a connection with a PHY on a different Dell qualified SATA device The physical link contains four wires that form two differential signal pairs One differential pair transmits signals while the other differential pair receives signals Both differential pairs operate simultaneously and allow concurrent data transmission in both the receive and the transmit directions Physical Disk A physical disk also known as hard disk drive consists of one or more rigid magnetic discs rotating about a central axle with associated read write heads and electronics A physical disk is used to store information data in a non volatile and randomly accessible memory space Glossary 57 POST POST short for Power On Self Test is a process performed before the operating system loads when the computer is turned on The POST tests various system components such as RAM the physical disks and the keyboard RAID Acronym for Redundant Array of Independent Disks originally Redundant Array of Inexpensive Disks It is an array of multiple independent physical disks managed together to yield higher reliability and or performance exceeding that of a single physical disk The virtual disk appears to the operating system as a single storage unit I O is expedited because several disks can be accessed simultaneously Redundant RAID levels provide data protection ROM Read only memory ROM also known as firmware is an integrate
