HP Business computers Select HP Business computers support RAID using Intel® Rapid Storage Technology software (v10 and higher) and a second SATA drive in the Upgrade Bay. External USB SATA drives connected to the computer or docking station cannot be used for migrating to RAID.ĮSATA drive, the same recommendations apply as stated for secondary drives in the computer Upgrade Bay. Device support is summarized in the following table and then explained in more detail below the table. Devices supported This section describes the devices supported for RAID migration, including the SATA drives, computers, and docking station.

With Recovery, however, the restoration of a single file or an entire hard drive is much simpler than with RAID 1 alone.ģ Operating systems and devices supported Operating systems supported HP RAID supports the Windows 8 operating system. With RAID 1 and Recovery, one drive can fail without causing the array to fail. Therefore, RAID 0 has no fault tolerance because it does not copy data to another hard drive. Fault tolerance is provided by redundancy.

Financial RAID Recovery Storage space may be wasted if the capacities of the primary and recovery hard drives are different (see HP SATA drive option kits on page 6).įault tolerance Fault tolerance is the ability of a RAID array to withstand and recover from a drive failure.

Payroll Only half of the total drive capacity can be used for storage.

RAID levels Function/Applications Advantages/Disadvantages RAID 1 Function: Advantages: Identical (mirrored) data is stored on two drives. However, RAID 0 offers no fault tolerance, which means that if one drive fails, the entire array fails. This allows data, especially large files, to be read faster because data is read simultaneously from both drives. RAID 0 RAID 0 stripes, or distributes, data across both drives.

Removing the fifth SATA port device restores normal operation. Enabling a fifth SATA port device causes the computer to freeze. NOTE: When the SATA controller is in RAID mode, it will only support up to 4 SATA port devices.

Term Definition Fault tolerance The ability of the computer to continue to operate if one drive fails. RAID terminology Some of the terms in the following table have a broader meaning, but they are defined in relation to the RAID implementation described in this guide. If users failed to perform one of these mundane tasks prior to a hard drive failure, they had to spend considerable time and money to recover even a portion of the data on the drive.Ģ RAID technology overview This chapter defines the terms used in this guide and describes the RAID technologies supported by select HP Business computers. These options were manually copying files to a backup drive or using cumbersome backup software. ġ Introduction Until recently, there were limited options for most computer users who wanted to protect their data from loss in the event of a hard drive failure.
