Page 3: Introduction
RAID technology takes advantage of Serial Advanced Technology Attachment (SATA) and the integration of RAID into the Intel Q965/ICH8-D0 chipset. The HP Compaq dc7700 and dx7300 Business PC prod- ucts are the first business desktops to incorporate RAID drive support through factory configurations. This... - Page 4 Mode RAID 0 RAID 1 RAID 5 RAID 0 + 1 Intel’s Matrix Technology * Not supported on HP Compaq dc7700 and dx7300 Business PCs. Purpose Striped for Performance. Mirrored for Protection. Parity for Accuracy. Mirrored and Striped. 4 logical drives on 2 physical disks, to emulate RAID 0 and 1.

Page 5: Basic Raid Types
RAID 0 with two hard drives (Striped) Even though HP supports RAID 0, it is not the recommended configuration for business PC users. Lack of redundancy causes less than half the reliability of a single hard drive system since the Mean Time Between Failure (MTBF) of RAID 0 is equal to the MTBF of an individual drive, divided by the number of drives. - Page 6 Performance - RAID 0 with two hard drives At a higher reliability cost with faster performance, HP Compaq dc7700 Business PC Convertible Mini- tower and dx7300 Microtower also allow for RAID 0 with three hard drives. RAID 0 with two or three hard drives is a supported 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 dc7700 and dx7300 Busi- ness PCs. RAID 1 provides high availability with minimal performance impact, as well as greater reliabil- ity 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. - Page 9 Table 5 RAID 5 with 3 hard drives (Parity) First Disk Data Segment 1 Data Segment 3 Parity for 5 and 6 Data Segment 7 Data Segment 9 Parity for 11 and 12 Data Segment 13 Data Segment 15 Parity for 17 and 18 In the previous table, each “Data Segment x”...

Using Intel Matrix Storage technology, you can configure the HP Compaq dc7700 Business PC Convert- ible Minitower or the HP Compaq dx7300 Business PC Microtower with two RAID volumes using three hard drives - a RAID 0 volume for ultimate performance, and a second volume as RAID 5 with reliability... -
Page 11: Configurations
Configurations Recommended configurations HP recommends factory configurations of the preinstalled RAID offerings for the HP Compaq dc7700 and dx7300 Business PCs. The preinstalled RAID offering is a RAID 1 volume of two identical SATA hard drives, and either two SATA 80GB/8MB cache or two SATA 160GB/8MB cache drives. -

HP Backup and Recovery. These steps are necessary for the F11 restore to function properly. HP also recommends keeping the default options in the RAID Option ROM and in the Windows RAID application. Options like “chunk” size for changing the size “stripe” size have more history in their defaults settings. -

To reset to factory settings, select Set Defaults and Exit. This option restores the original • factory defaults. CAUTION: Do NOT turn the computer power off while the ROM is saving the F10 Computer Setup changes as the CMOS could become corrupted. Only turn the computer off after exiting the F10 Setup screen. -

Configuring RAID Volume using the Option ROM Once you are in the Option ROM, if there are no previous RAID member hard drives, press Ctrl + I to enter the RAID configuration utility. - Page 16 With Create RAID Volume selected, press Enter to access the Create Volume screen. Select or enter the desired RAID Level. Use the information on the bottom half of the screen if neces- sary.

Page 17: Notes For Operating System Installation
After creating a RAID disk volume in the option ROM, you can install the operating system. • HP provides a download for the required F6 disk for Windows XP CD installation. • Customer-created images MUST account for the RAID controller. -

The configuration steps are for application usage and supported RAID migrations. Console Software Installation The Intel Matrix Storage Manager Software has been preloaded in all HP Compaq dc7700 and dx7300 Business desktops at “C:\COMPAQ\Intel MSM”. To execute the software, run the setup.exe file. You can also get this software from the HP and Intel Web sites. -

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. -

NOTE: Back up all data before proceeding. NOTE: HP Compaq dc7700 and dx7300 Business PC products support only RAID based on three identi- cal SATA hard drives RAID in either RAID 0 or RAID 5 or Matrix Mode of RAID 0 and RAID 5. - Page 25 Type the RAID Volume 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 128KB). There is a performance relation between the type of data and the strip sizes.
- Page 26 Click Next to display the selection of hard drives that will be part of this RAID volume. Select all three hard drives (Port 0, Port 1, and Port 2), and then click the right arrow to place them in the Selected box. Click Next.
- Page 27 Selection all hard drive members of the RAID volume, and then click the right arrow to place all three hard drives in the Selected box. Click Next. Complete the volume size selection screen, and then click Next. NOTE: If users consume all available storage for this RAID volume, there will be no space to create another RAID volume for this hard drive, thereby not allowing for Matrix mode RAID.
