book.book Page 10 Monday, September 15, 2008 2:47 PM 1 Turn off the system and any devices. 2 Ground yourself by touching an unpainted metal surface on the chassis before touching anything inside the system. 3 While you work, periodically touch an unpainted metal surface on the chassis to dissipate any static electricity that might harm the internal components. 4 Disconnect your system and devices from their power sources.
book.book Page 11 Monday, September 15, 2008 2:47 PM Overview The Dell™ Serial-Attached SCSI (SAS) 6/iR controller is Dell’s next generation controller with integrated redundant array of independent disks (RAID) capabilities. SAS technology is not backward compatible with the previous generation of SCSI devices. All SAS 6/iR controllers are half-length, standardheight PCI-E cards, except for the SAS 6/iR Integrated controller on the blade servers and on the Precision workstations.
book.book Page 12 Monday, September 15, 2008 2:47 PM About RAID RAID is a group of multiple independent physical disks that provide high performance or better data availability by increasing the number of drives used for saving and accessing data. A RAID disk subsystem improves I/O performance and data availability. The physical disk group appears to the host system as a single storage unit. Data throughput improves because multiple disks can be accessed simultaneously.

NOTE: There is an option to create a hot spare for a RAID 1 virtual disk.
book.book Page 45 Monday, September 15, 2008 2:47 PM Synchronizing a Virtual Disk Synchronizing a virtual disk means that the firmware synchronizes the data on the secondary disk(s) with the data on the primary disk of the mirror. Follow these steps to start synchronization for a RAID 1 virtual disk: 1 Select Synchronize Mirror. 2 Press Y to start the synchronization or N to cancel it.
book.book Page 46 Monday, September 15, 2008 2:47 PM replacing drives. Volumes that are migrated to another controller will be inactive and must therefore be activated.To activate a virtual disk see "Activating a Virtual Disk" on page 45. Deleting a Virtual Disk NOTICE: Before deleting a virtual disk, be sure to back up all data on the virtual disk that you want to keep. Follow these steps to delete a selected virtual disk: 1 Select Delete Virtual Disk.
book.book Page 47 Monday, September 15, 2008 2:47 PM NOTE: During the rebuilding of a volume the synchronization will be restarted from the beginning if a hard drive is added or removed from the system.

book.book Page 65 Monday, September 15, 2008 2:47 PM Glossary This section defines or identifies technical terms, abbreviations, and acronyms used in this document. A Adapter An adapter enables the computer system to access peripheral devices by converting the protocol of one bus or interface to another. An adapter may also provide specialized function. Adapters may reside on the system board or be an add-in card. Other examples of adapters include network and SCSI adapters.
book.book Page 66 Monday, September 15, 2008 2:47 PM Controller A chip that controls the transfer of data between the microprocessor and memory or between the microprocessor and a peripheral device such as a physical disk or the keyboard. In Storage Management, the hardware or logic that interacts with storage devices to write and retrieve data and perform storage management. RAID controllers perform RAID functions such as striping and mirroring to provide data protection.
book.book Page 67 Monday, September 15, 2008 2:47 PM F Firmware Software stored in read-only memory (ROM) or Programmable ROM (PROM). Firmware is often responsible for the behavior of a system when it is first turned on. A typical example would be a monitor program in a system that loads the full operating system from disk or from a network and then passes control to the operating system.
book.book Page 68 Monday, September 15, 2008 2:47 PM M MHz Megahertz or one million cycles per second is a unit of frequency commonly used to measure the operating speed of a computer processor or any other electronic component. Mirroring The process of providing complete redundancy using two physical disks, by maintaining an exact copy of one physical disk’s data on the second physical disk.
book.book Page 69 Monday, September 15, 2008 2:47 PM connections. These connections fan out from the switch, leading directly to the devices where the data needs to go. Every device has its own dedicated connection, so devices no longer share bandwidth like they do on a normal bus. PHY The interface required to transmit and receive data packets transferred across the serial bus. Each PHY can form one side of the physical link in a connection with a PHY on a different Dell-qualified SATA device.
book.book Page 70 Monday, September 15, 2008 2:47 PM ROM Read-only memory (ROM), also known as firmware, is an integrated circuit programmed with specific data when it is manufactured. ROM chips are used not only in computers, but in most other electronic items as well. Data stored in these chips is nonvolatile i.e., it is not lost when the power is turned off. Data stored in these chips is either unchangeable or requires a special operation such as flashing to change.
book.book Page 71 Monday, September 15, 2008 2:47 PM SCSIport SCSIport driver is a Microsoft® driver for Windows® XP storage architecture, delivering SCSI commands to the storage targets. The SCSIport driver works well with storage using parallel SCSI. Serial Architecture Serial architectures have emerged to deliver higher performance by allowing more bandwidth per device pathway than their parallel counterparts.
book.book Page 72 Monday, September 15, 2008 2:47 PM Storport The Storport driver has been designed to replace SCSIport and work with Windows 2003 and beyond. In addition, it offers better performance for storage controllers, providing higher I/O throughput rates, improved manageability, and an upgraded miniport interface. Stripe Element A stripe element is the portion of a stripe that resides on a single physical disk. Striping Disk striping writes data across all physical disks in a virtual disk.
