Features of the 3ware 9000 series controllers include: Advanced RAID features for greater data protection and management. PCI slot that meets the Plug and Play and PC99 specifications. For all 3ware 9000 series models, install the card in a 64- Note: bit, 66MHz PCI or PCI-X slot for best performance. Drives may be of any capacity or physical form factor. If the drives are not already installed in the computer, install them. Connect the interface cables to the drives. Close up the case. Power on the system. www.3ware.com. Save your changes and exit. Specify a hot spare (optional). Install the 3ware driver and make the units available to the operating system. For details see one of the following: “Driver Installation Under Windows” on page 53 “Driver Installation Under Linux”. It contains the following topics: “Before You Begin” things you should consider before starting installation, and tools and equipment you will need. “Safety Factors” personal safety and to protect your equipment and data. Be sure to read this section. The amount of clearance you need will depend on the number of drives you will be connecting to the controller. Safety Factors Be sure to follow the guidelines presented on the next few pages to insure your own safety, and that of your equipment. Handle the 3ware RAID controller by its edges or by the black rail and metal bracket at its two ends. Do not touch any pin, contact, lead or component on the 3ware RAID controller. The earlier models use Pchip v1.4 and are not BBU-compatible. The more recent models use Pchip v1.5 and are BBU-compatible.http://www.roycraft.ca/userfiles/bosch-instant-water-heater-manual.xml

When you work with 3ware software, “unit” is the term used to refer to an array of disks that is configured and managed through the 3ware software. The stripe size is configurable in 3ware BIOS Manager (3BM). Requires a minimum of two drives. When drives are configured in a striped disk array, large files are distributed across the multiple disks using RAID 0 techniques. Like disks in other RAID configurations, single disks contain 3ware Disk Control Block (DCB) information and are seen by the OS as available units.https://tallteknologier.com/userfiles/bosch-integra-300-series-dishwasher-manual.xml Used to store data locally on the drive before it is.

The steps below describe how to do this through the BIOS (3BM). For information about using 3DM 2, see 3ware 9000 Series Serial ATA RAID Controller User Guide. After installing the 3ware 9000 controller in your system, go into the BIOS for your computer system to check and change the boot order. This is necessary because most systems automatically change the boot order when they detect a newly installed controller and device. Will the unit you have created be your system's boot device. If so, you will install the driver for the controller as you install the operating system. A drive or unit managed by the 3ware RAID controller may be configured to be your system’s boot device. Or, you can use another device as your boot device, such as a disk attached to the motherboard. If you are installing Windows, you must create a 3ware driver diskette. If Windows is already installed on another device, you may install the 3ware driver from either the 3ware software CD-ROM or from a diskette. Insert the 3ware driver diskette and press Enter. This wizard guides you through installing the 3ware drivers (see Figure 17). Note that you will see screens for the installation of two drivers during this process. This wizard guides you in installing the 3ware drivers (see Figure 21). Note that you will see screens for the installation of two drivers during this process.

(You will connect one cable for each hard drive you will attach.) To install the controller in the computer 1 If the computer is running, shut it down. Page 26 Installing the Hardware 7 Press down gently on the edge of the 3ware RAID controller directly above the slot until it is fully seated. 8 Check that the 3ware RAID controller’s metal bracket covers the hole in the case and secure the bracket with the screw that was used to secure the filler bracket in step 5. To connect the interface cables to the drives 1 If your drives are not already installed in the computer chassis or hot swap carriers, install them now.

Turn off power to the computer and disconnect the power cord from the outlet. 2 Open the computer case according to the manufacturer’s instructions. 3 Find the PCI slot you want to use for the serial RAID controller. 4 Remove the metal filler bracket for the slot. Finishing Up After you have installed the controller in the computer and attached appropriate cables to the controller and drives, complete the following steps to complete the hardware installation. Page 31 Moving Units from an 8000 Controller to a 9000 Controller Moving Units from an 8000 Controller to a 9000 Controller It is possible to move your 8000 storage units to a 9000 series controller. You will then have the advantages of the 9000 series controller. The drive units must be in normal mode before moving the units. Incomplete, degraded, rebuilding, or initializing units cannot be converted. In addition, RAID 0, 10, and 5 units must use a standard 64 KB stripe size. Page 32 Installing the Hardware To move units under Linux or FreeBSD 1 Upgrade your driver to the 9000 series driver. (For details, refer to the Linux or FreeBSD Driver Installation section.) 2 Run the conversion utility to convert the units. 3 Power down the system, disconnect the drives from the 8000 controller and remove the controller from the system. 4 Install the 9000 controller and attach the drives to the 9000 board, as described earlier in this section. Page 33 Moving Units from an 8000 Controller to a 9000 Controller 4 Reboot the system and enter the 3ware 9000 series BIOS (3BM) by pressing Alt-3. Enable the Export JBOD policy on the Policy screen. (The next section in this guide, “Configuring Units”, describes how to work in 3BM. Additional information about 3BM is available in 3ware 9000 Series Serial ATA RAID Controller User Guide.) 5 Press the F8 or Esc key to save and exit. Page 34 Installing the Hardware 26 3ware 9000 Series Serial ATA RAID Controller Installation Guide Page 35 Configuring Units After you have physically installed your 3ware RAID controller and connected it to your disk drives, you configure how the drives connected to the controller will be used in RAID arrays. Page 36 Configuring Units Note: This section describes how to configure your RAID arrays as part of the installation process. For complete information about using 3ware BIOS Manager (3BM), including how to use it to change existing configurations, and for information about how to define and change the configuration using 3ware Disk Manager (3DM 2), see the 3ware 9000 Series Serial ATA RAID Controller User Guide. Note: You must attach drives before you can configure RAID arrays. Page 37 Understanding RAID Concepts and Levels disk arrays achieve highest transfer rates and performance at the expense of fault tolerance. ? Distributed Parity. Parity works in combination with striping on RAID 5 and RAID 50. Parity information is written to each of the striped drives, in rotation. Should a failure occur, the data on the failed drive can be reconstructed from the data on the other drives. ? Hot Spare. Page 38 Configuring Units cause a system hang, depending on your operating system. RAID 0 arrays are not recommended for high availability systems unless additional precautions are taken to prevent system hangs and data loss. ? RAID 1. Also known as a mirrored array. Mirroring is done on pairs of drives. Mirrored disk arrays write data to two drives using RAID 1 algorithms. This gives your system fault tolerance by preserving the data on one drive if the other drive fails. Page 39 Determining What RAID Level to Use Disk as a replacement for JBOD, to take advantage of advanced features such as OCE, and RLM. JBOD units are not fault tolerant and therefore not recommended for high availability systems unless additional precautions are taken to prevent system hangs and data loss. ? Hot Spare. A single drive, available online, so that a redundant array can be automatically rebuilt in case of drive failure. It includes the following sections. Starting the 3BM configuration utility.

(For information about how many drives to select for a given RAID level, see Table 2 on page 31.) Note: To include drives that are part of an existing unit you must first delete the other unit. Be cautious in doing this, as any existing data on that unit will be overwritten. Figure 10. Page 50 Configuring Units Figure 11. Create Disk Array Display, RAID 0 Example Figure 12.
