  • Page 6 Performance - RAID 0 with two hard drives At a higher reliability cost with faster performance, the HP Compaq dc7800 Business PC Convertible Minitower also allows for RAID 0 with three hard drives. RAID 0 with two or three hard drives is a sup- ported configuration.

  • Page 7: Raid 1 With Two Hard Drives (Mirror)

    Because it is a very cost-effective way to increase system storage reliability and a great value proposition, RAID 1 is the only RAID configuration that HP preconfigures for HP Compaq dc7800 Business PCs. RAID 1 provides high availability with minimal performance impact, as well as greater reliability compared to a single hard drive configuration.

  • Page 8: Raid 5 With Three Hard Drives

    Figure 3 Reliability: RAID 1 - Mirroring RAID 5 with three hard drives RAID 5 has been used in servers for many years and is one of the most common types of RAID. RAID 5 uses striping with parity data in distributed blocks across all member disks. Therefore, the mass storage controller can simultaneously write new information to two hard drives and parity information to the third hard drive, so if one hard drive fails, the RAID controller can rebuild all the information after the volume degradation occurred.

    Migration to RAID 1 from two non-RAID hard drives using Intel Matrix Stor- age Console NOTE: HP Compaq dc7800 Business PC products only support RAID based on two identical SATA hard drives in either RAID 0 or RAID 1 or Matrix Mode of RAID 0 and RAID 1.
  • Page 21 Open the Intel Matrix Storage Console and in the left pane select either Protect data from a hard drive failure with RAID 1 or Improve storage performance with RAID 0. In the right pane, select Protect data from a hard drive failure with RAID 1. Click Create a RAID 1 volume to open a verification window.

  • Page 22: Degradation

    Degradation In the unlikely event that one of your hard drives malfunctions, you will be notified with the following mes- sage: Run the Intel Matrix Storage Console application on the system experiencing a degradation to iden- tify the hard drive that failed and to which port it is connected. After identifying the hard drive, close all applications, shut down the operating system, power down the unit, unplug the power cord, and replace the defective hard drive.

  • Page 36 Click Finish to start the migration process, which can take a few hours. Reboot the system after the migration finishes. NOTE: Back up all data before proceeding. After the first RAID volume has been created, create the second RAID volume by opening the Intel Matrix Storage Console, clicking View>Advanced Mode, and then clicking Actions/Create RAID Volume from Existing Hard Drive.
  • Page 37 Click Next. Use the same values you entered in the previous RAID volume confirmation and type the RAID Vol- ume Name, select the RAID Level (for three hard drive RAID 0 or RAID 5 only), and select the Strip Size. NOTE: HP currently supports only the default Strip Size (in this case 64KB).
  • Page 38 Because this is the second volume for this set of hard drives, select the existing name in the Avail- able box (Array 0000), and then click the right arrow to move this array into the Selected box. Click Next. The Specify Volume Size screen is grayed out because the second volume of this matrix mode takes the remaining space.

  • Page 41: Migration To Raid Matrix Mode (0 + 1) From Two Non-Raid Hard Drives Using Matrix Storage Console

    Migration to RAID Matrix Mode (0 + 1) from two non-RAID hard drives using Matrix Storage Console The migration process for two hard drives to RAID Matrix Mode (0 + 1) is very similar to the process described in the section about migration of three hard drives to matrix mode RAID (0 + 5). The difference in the process is selecting two hard drives as part of the volume created and selecting RAID 5 instead of RAID 1.
