You can review and change these features as a final step in your initial setup, or you can make changes to them later, at your convenience. These features include: • Controller and unit policies, such as Auto Rebuild, Auto Verify, use of write cache, use of queueing mode, and selection of a StorSave profile • Email notification of alarms and other events

2 Introducing the 3ware® 9590SE-4ME RAID Controller The 3ware 9590SE-4ME RAID controller is a 4-lane (x4) PCI Express® card. It can be installed in any of the available x4 or x8 PCI Express slots on your Power Mac® G5 (PowerPC™-based). (The x16 slot is normally reserved for your graphics card.) It features: • Support for up to 4 SATA drives. • AMCC’s remote management software, 3ware Disk Manager 2 (3DM®2) which simplifies storage configuration and management through a web browser. • An e

System Requirements System Requirements 3ware 9590SE-4ME RAID controllers require the following: • Drives Drives must be 3.5" and meet serial ATA 150 (SATA-1) or serial ATA 300 (SATA 2) Gb/s standards. SATA 2 drives will have better performance. A list of drives that have been tested is available at http://www.3ware.com/products/cables.asp • Operating System and Computer Mac OS 10.4 or later, running in a Power Mac G5 (PowerPC-based) with PCI Express.

Chapter 2. Introducing the 3ware® 9590SE-4ME RAID Controller Understanding RAID Concepts and Levels 3ware RAID controllers use a Redundant Array of Inexpensive Disks (RAID) to increase your storage system’s performance and provide fault tolerance (protection against data loss). This section organizes information about RAID concepts and configuration levels into the following topics: • “RAID Concepts” on page 6 • “Available RAID Configurations” on page 7 • “Determining What RAID Level to Use

Understanding RAID Concepts and Levels Available RAID Configurations The following RAID levels and configurations are available for drives attached to a 9590SE-4ME 3ware RAID controller: • RAID 0 • RAID 1 • RAID 5 • RAID 10 • Single Disk • Hot Spare For how to configure RAID units, see “Configuring a New Unit” on page 34. RAID 0 RAID 0 provides improved performance, but no fault tolerance. Since the data is striped across more than one disk, RAID 0 disk arrays achieve high transfer rates be

Chapter 2. Introducing the 3ware® 9590SE-4ME RAID Controller preserving the data on one drive if the other drive fails. Fault tolerance is a basic requirement for critical systems like web and database servers. 3ware uses a patented technology, TwinStor®, on RAID 1 arrays for improved performance during sequential read operations. With TwinStor technology, read performance is twice the speed of a single drive during sequential read operation. The adaptive algorithms in TwinStor technology bo

Understanding RAID Concepts and Levels RAID 10 RAID 10 is a combination of striped and mirrored arrays for fault tolerance and high performance. When drives are configured as a striped mirrored array, the disks are configured using both RAID 0 and RAID 1 techniques, thus the name RAID 10 (see Figure 4). A minimum of four drives are required to use this technique. The first two drives are mirrored as a fault tolerant array using RAID 1. The third and fourth drives are mirrored as a second fa

Chapter 2. Introducing the 3ware® 9590SE-4ME RAID Controller Determining What RAID Level to Use Your choice of which type of RAID unit (array) to create will depend on your needs. You may wish to maximize speed of access, total amount of storage, or redundant protection of data. Each type of RAID unit offers a different blend of these characteristics. The following table provides a brief summary of RAID type characteristics. Table 3: RAID Configuration

3ware Tools for Configuration and Management Through drive coercion, the capacity used for each drive is rounded down so that drives from differing manufacturers are more likely to be able to be used as spares for each other. The capacity used for each drive is rounded down to the nearest GB for drives under 45 GB (45,000,000,000 bytes), and rounded down to the nearest 5 GB for drives over 45 GB. For example, a 44.3 GB drive will be rounded down to 44 GB, and a 123 GB drive will be rounded

Chapter 2. Introducing the 3ware® 9590SE-4ME RAID Controller Monitoring, Maintenance, and Troubleshooting Features Several 3ware RAID controller features aid in monitoring and troubleshooting your drives. • SMART Monitoring (Self-Monitoring, Analysis and Reporting Technology) automatically checks a disk drive's health every 24 hours and reports potential problems. This allows you to take proactive steps to prevent impending disk crashes. SMART data is checked on all disk drives (array mem
