HP EliteBook Folio 9470m Ultrabook Unboxing (HD) by TechBargains

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. These options were manually copying files to a backup drive or using cumbersome backup software. 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. Server and desktop computer users have long enjoyed the security and benefits of RAID (Redundant Array of Independent Disks) technology to recover data in the event of drive failure.

HP now offers a simple RAID solution for notebook computer users who need to protect data on a Serial ATA (SATA) disk drive in case of drive failure or virus attacks. HP’s RAID solution also benefits computer users who frequently work with large files and want to improve the storage performance of their computer.

RAID technology overview

This chapter defines the terms used in this guide and describes the RAID technologies supported by select HP Business computers.

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.
HP Elitebook Folio 9470m User Manual 5

TermDefinition
Fault toleranceThe ability of the computer to continue to operate if one drive fails. Fault tolerance is
often used interchangeably with reliability, but the two terms are different.
HDDOne physical hard disk drive in the RAID array.
Option ROMA software module inside the system’s BIOS that provides extended support for a
particular piece of hardware. The RAID option ROM provides boot support for RAID
volumes as well as a user interface for managing and configuring the system’s RAID
volumes.
Primary driveThe main internal hard drive in the computer.
RAID arrayThe physical drives that appear as one logical drive to the operating system.
RAID migrationThe change of data from a non-RAID to RAID configuration. “RAID level migration,” or
the change of data from one RAID level to another, is not supported.
RAID volumeA fixed amount of space across a RAID array that appears as a single hard drive to the
operating system.
Recovery driveThe hard drive that is the designated mirror (copy of the primary) drive in a RAID 1 and
Recovery volume.
ReliabilityThe likelihood—over a period of time—that a hard drive can be expected to operate
without failure, also known as mean time before failure (MTBF).
StripeThe set of data on a single hard drive in a RAID volume.
StripingThe distribution of data over multiple disk drives to improve read/write performance.
SSD (solid-state drive)A solid-state drive is a flash-based or DRAM-based hard drive with no rotating media.
SED (self-encrypting drive)A self-encrypting drive is a hard drive that uses hardware encryption to protect the data
on the drive.
mSATA moduleAn mSATA module is a flash-memory module with an mSATA connector.

RAID modes supported

The RAID modes supported by HP Business computers include RAID 0, RAID 1, RAID 5, and Flexible data protection (Recovery) as described below. RAID modes 0, 1, and Recovery require two SATA hard drives. RAID mode 5 requires three SATA hard drives. This can be accomplished by inserting a third SATA hard drive into the upgrade bay of specially-equipped computers. RAID 10 is not supported.

HP Elitebook Folio 9470m User Manual 7HP Elitebook Folio 9470m User Manual 9HP Elitebook Folio 9470m User Manual 11NOTE: When the SATA controller is in RAID mode, it will only support up to 4 SATA port devices. Enabling a fifth SATA port device causes the computer to freeze. Removing the fifth SATA port device restores normal operation.
HP Elitebook Folio 9470m User Manual 13

RAID 0

RAID 0 stripes, or distributes, data across both drives. This allows data, especially large files, to be read faster because data is read simultaneously from both drives. However, RAID 0 offers no fault tolerance, which means that if one drive fails, the entire array fails.

RAID 1

RAID 1 copies, or mirrors, identical data on two hard drives. If one hard drive fails, RAID 1 allows data to be recovered from the other hard drive.

RAID 5

RAID 5 distributes data across three hard drives. If one hard drive fails, RAID 5 allows data to be recovered from the other two hard drives.

Flexible data protection (Recovery)

Flexible data protection (Recovery) is a feature of Intel® Rapid Storage Technology software. Recovery enhances RAID 1 functionality with several features that make it easier for users to mirror data to a designated recovery drive. For example, Recovery allows users to determine how the recovery volume is updated, either continuously (the default) or on request. Recovery also enables docking and undocking of the computer if the second drive is in the docking station’s bay.

RAID mode summary

The following table describes the functions, applications, and advantages and disadvantages of the supported RAID modes.

HP Elitebook Folio 9470m User Manual 29

4 Chapter 2 RAID technology overview

Fault tolerance

Fault tolerance is the ability of a RAID array to withstand and recover from a drive failure. Fault tolerance is provided by redundancy. Therefore, RAID 0 has no fault tolerance because it does not copy data to another hard drive. With RAID 1 and Recovery, one drive can fail without causing the array to fail. With Recovery, however, the restoration of a single file or an entire hard drive is much simpler than with RAID 1 alone. With RAID 5, one of the three hard drives can fail without causing the array to fail.

Performance

Performance is easy to understand, but it is difficult to measure because it involves several factors, some of which are beyond the scope of this document. Overall storage performance is determined by write performance and read performance, both of which vary based on the RAID technology selected.

  • RAID 0 (striping) improves overall storage performance because data can be written and read simultaneously across two hard drives.
  • Recovery and RAID 1 (mirroring) writes the same data to both hard drives; therefore, write performance may be slower. However, data can be read from both hard drives, so the read performance can be higher than that of a single non-RAID hard drive.
  • RAID 5 performs at a level between RAID 0 and RAID 1.

HP SATA drive option kits

HP offers SATA drive option kits for the computer Upgrade Bay and the docking station’s SATA-swappable bay to support RAID migration. For optimal RAID performance, it is recommended that both drives have the same speed. However, supported HP Business computers allow drives with different speeds to be used in a RAID volume.

Drives of different capacities are also supported for RAID migration, as long as the capacity of the secondary (recovery) drive is equal to or greater than that of the primary drive. For example, if the primary drive is 200 GB, then at least a 200-GB drive is required in the Upgrade Bay to create a RAID volume. If the capacity of the secondary drive is larger than that of the primary drive, the excess capacity of the secondary (or third) drive will not be accessible. If, for example, the primary drive is 160 GB and the secondary drive is 250 GB, only 160 GB of the secondary drive will be usable in a RAID configuration. Therefore, for optimal use, it is recommended that both drives have the same capacity.

eSATA hard drives (select models only)

External SATA, or eSATA, is an external interface that allows a SATA drive to achieve data transfer speeds up to 6 times that of a SATA drive using a standard USB 2.0 interface. The following illustration shows a supported computer with a primary hard drive (1) and an eSATA drive (2) connected to the eSATA port (select models only) to allow Recovery. Regarding the capacity of the

HP Elitebook Folio 9470m User Manual 41

8 Chapter 3 Operating systems and devices supported

Intel Rapid Storage Technology

Intel® Rapid Storage Technology supports the following Recovery features.

Advanced Host Controller Interface

The Advanced Host Controller Interface (AHCI) is a specification that allows the storage driver to enable advanced SATA features such as Native Command Queuing and hot plug capability. AHCI must be enabled in the Computer Setup (BIOS) for these features to apply (see Enable RAID using the Computer Setup (BIOS) (f10) on page 12). AHCI is enabled by default on supported HP Business computers.

Native Command Queuing

A read/write drive head writes data to a hard drive platter in concentric circles (tracks) based on the order in which the write request was received. Because applications rarely request data in the same order that it was written to the platter, long delays (latency) would result if the drive head had to locate data in the exact order that the hard drive receives read requests. Native Command Queuing (NCQ) allows SATA hard drives to accept multiple commands and change their execution order to improve performance. This is analogous to the way an elevator reorders floor requests to minimize travel time and mechanical wear. Similarly, NCQ reduces the latency and unnecessary drive head movement required to execute multiple outstanding read/write requests, resulting in increased performance and reliability. NCQ requires support from the Computer Setup (BIOS), SATA controller, and controller driver.

Hot plug capability

Hot plug capability allows the SATA recovery hard drive to be removed or inserted while the computer is running. Hot plug capability is supported when the recovery hard drive is connected to the eSATA port or located in the docking station’s SATA-swappable bay. For example, the recovery hard drive in the docking station’s SATA-swappable bay can be removed while the computer is running if you need to temporarily insert an optical drive in the bay. Hot plug capability also allows you to dock and undock the computer at any time.

Intel Rapid Recover Technology

Intel Rapid Storage Technology supports the following recovery features.

Mirror update policies

With Recovery, you can determine how often the mirror hard drive is updated: continuously or on-request. When using the continuous update policy, data on the primary drive is simultaneously copied to the mirror drive as long as both drives are connected to the system. If you undock the computer while using the docking station’s recovery drive, all new or revised data on the primary hard drive is automatically copied to the recovery hard drive when the notebook is redocked. This policy also allows for an unfinished mirroring operation to be completed if it was interrupted when you undocked the notebook.

When using the update on-request policy, data on the primary hard drive is copied to the mirror hard drive only when you request it by selecting Update Recovery Volume in Recovery. After the request, only the new or updated files on the primary drive are copied to the mirror hard drive. Prior to updating the mirror hard drive, the on-request policy allows a file to be recovered if the corresponding file on the primary hard drive is corrupted. The on -request policy can also protect data on the mirror hard drive if the primary hard drive is attacked by a virus, provided you do not update the mirror hard drive after the virus attack.

HP Elitebook Folio 9470m User Manual 49

Automatic hard drive switching and rapid recovery

If the primary hard drive fails, Recovery automatically switches to the mirrored drive without user intervention. Recovery displays a message to notify you of the primary hard drive failure. In the meantime, the computer can boot from the mirrored hard drive. When a new primary hard drive is installed and the computer is booted, Recovery’s rapid recovery feature copies all mirrored data to the primary hard drive.
