SCSI to SATA RAID Subsystem | Administrator’s Manual 1 RAID Functions: Introduction | en 9 RAID Functions: Introduction Redundant Arrays of Independent Disks, or RAID, offers the following advantages: availability, capacity, and performance. Choosing the right RAID level and drive failure management can increase capacity and performance, subsequently increasing availability. Bosch's external RAID controllers and subsystems provide complete RAID functionality and enhanced drive failure management. 1.
PAGE 10
en | RAID Functions: Introduction 1.3 SCSI to SATA RAID Subsystem | Administrator’s Manual RAID Levels Using a RAID storage subsystem has the following advantages: • • Provides disk spanning by weaving all connected drives into one single volume. Increases disk access speed by breaking data into several blocks when reading/writing to several drives in parallel. With RAID, storage speed increases as more drives are added as the channel bus allows.
PAGE 11
SCSI to SATA RAID Subsystem | Administrator’s Manual 1.3.1 RAID Functions: Introduction | en 11 NRAID Disk Spanning NRAID stands for Non-RAID. The capacity of all drives is combined to become one logical drive (no block striping). In other words, the capacity of the logical drive is the total capacity of the physical member drives. NRAID does not provide data redundancy. NRAID Minimum Disks Required 1 Capacity N Redundancy No Fig. 1.2 1.3.
PAGE 12
en | RAID Functions: Introduction 1.3.3 SCSI to SATA RAID Subsystem | Administrator’s Manual RAID0 Disk Striping RAID0 provides the highest performance but no redundancy. Data in the logical drive is striped (distributed) across several physical drives. RAID0 Minimum Disks Required 2 Capacity N Redundancy No Fig. 1.4 1.3.4 RAID0 RAID1 Disk Mirroring RAID1 mirrors the data stored in one hard drive to another. RAID1 can only be performed with two hard drives.
PAGE 13
SCSI to SATA RAID Subsystem | Administrator’s Manual 1.3.5 RAID Functions: Introduction | en 13 RAID (0+1) Disk Striping with Mirroring RAID (0+1) combines RAID0 and RAID1 - Mirroring and Striping. RAID (0+1) allows multiple drive failure because of the full redundancy of the hard drives. If there are more than two hard drives assigned to perform RAID1, RAID (0+1) will be automatically applied. RAID (0+1) Minimum Disks Required 4 Capacity N/2 Redundancy Yes Fig. 1.
PAGE 14
en | RAID Functions: Introduction 1.3.6 SCSI to SATA RAID Subsystem | Administrator’s Manual RAID3 Disk Striping with Dedicated Parity Disk RAID3 performs Block Striping with Dedicated Parity. One drive member is dedicated to storing the parity data. When a drive member fails, the controller can recover/regenerate the lost data of the failed drive by comparing and re-calculating data on the remaining drives. RAID (0+1) Minimum Disks Required 3 Capacity N-1 Redundancy Yes Fig. 1.7 1.3.

SCSI to SATA RAID Subsystem | Administrator’s Manual 1.4 1.4.1 RAID Functions: Introduction | en 15 Spare Drives Local Spare Drives A Local Spare Drive is a standby drive assigned to serve one specified logical drive. When a member drive of this specified logical drive fails, the Local Spare Drive becomes a member drive and automatically starts to rebuild. Fig. 1.9 1.4.2 Local (Dedicated) Spare Global Spare Drives A Global Spare Drive serves more than one specified logical drive.

If yes, rebuild is automatically started. If there is no Local Spare available, the controller will search for a Global Spare.

en | RAID Functions: Introduction 1.5.2 SCSI to SATA RAID Subsystem | Administrator’s Manual Manual Rebuild When a user applies a forced-manual rebuild, the controller will first examine whether there is any Local Spare assigned to the logical drive. If yes, it will automatically start to rebuild. If there is no Local Spare available, the controller will search for a Global Spare. If there is a Global Spare, logical drive rebuild will be automatically conducted. Fig. 1.

SCSI to SATA RAID Subsystem | Administrator’s Manual 1.6 Logical Volume (Multi-Level RAID) 1.6.1 What Is a Logical Volume? RAID Functions: Introduction | en 19 Fig. 1.15 Logical Volume A logical volume is a combination of RAID0 (Striping) and other RAID levels. Data written to a logical volume is first broken into smaller data segments and striped across different logical drives in a logical volume.
PAGE 20
en | RAID Functions: Introduction SCSI to SATA RAID Subsystem | Administrator’s Manual As illustrated above, Configuration A is a RAID5 logical drive consisting of 24 physical drives. Configuration B is a logical volume made of four RAID5 logical drives. Fig. 1.
PAGE 21
SCSI to SATA RAID Subsystem | Administrator’s Manual RAID Functions: Introduction | en 21 Fig. 1.18 Logical Volume with Drives on Different Channels As illustrated above, if one of the drive channels fails, each logical drive loses one of its members. Logical drives still have the chance to rebuild its members. Data remains intact and the rebuild can be performed after the failed channel is recovered. No access interruptions to the logical volume will be experienced from the host side. 1.6.
PAGE 22
en | RAID Functions: Introduction SCSI to SATA RAID Subsystem | Administrator’s Manual When a logical drive is used as a member of a logical volume, this logical drive can no longer be partitioned in “View and Edit Logical Drives.” Instead, the Logical Volume can be divided into eight partitions in “View and Edit Logical Volume.” The procedure for partitioning a logical volume is the same as that for partitioning a logical drive.

A Fibre Channel supports up to 126 drives in a loop.
PAGE 27
SCSI to SATA RAID Subsystem | Administrator’s Manual Fig. 2.5 RAID Planning | en 27 Physical Locations of Drive Members A drive can be assigned as the Local Spare Drive that serves one specific logical drive, or as a Global Spare Drive that participates in the rebuild of any logical drive. Spares automatically joins a logical drive in order to replace a failed member when a drive fails. Spares are not applicable to logical drives that have no data redundancy (NRAID and RAID 0). Fig. 2.
