Page 9: Chapter 1 Overview
1 Overview The disk array system uses groups of inex- pensive disks to provide flexibility when balancing data availability, access rate, and capacity management needs. High data availability is achieved by using the fault tolerance features of RAID (Redundant Array of Inexpensive Disks); hot spare disks with automatic on-line rebuild;... -
Page 10: Features
S16 Serial ATA Disk Array Systems Features The main features of the disk array system are listed as follows. Refer to the specifications table on page 31 for more detailed information. • Operating system independent • Up to eight JBOD, RAID 0, 1, 3, 5, 0+1, 30, or 50 array groups •... -
Page 11: Understanding Raid
S16 Serial ATA Disk Array Systems Understanding RAID Read this section to understand how to balance data availability, access rate, and capacity man- agement needs. Just a Bunch Of Disks Just a Bunch Of Disks (JBOD) consists of two or more disks that can be different sizes. Disk 1 is completely filled, then disk 2, disk 3, and so on until the final disk is full. - Page 12 S16 Serial ATA Disk Array Systems A RAID 0 array is useful in the following situations: • Storing program image libraries or run-time libraries for rapid loading. A backup exists because these libraries are usually supplied on read-only media.
- Page 13 S16 Serial ATA Disk Array Systems RAID 3 In RAID 3, data is divided into pieces; the parity of these pieces is calculated; and the pieces are written to separate disks in parallel with the writing of the parity to a dedicated disk. This process is called striping with parity.
-
Page 14: Hot Spare Disks
S16 Serial ATA Disk Array Systems RAID 5 In RAID 5, data is divided into pieces; the parity of these pieces is calculated; and the pieces and parity are written to separate disks in parallel. The parity is written to a different disk each time. -
Page 15: Summary Of Raid Levels
S16 Serial ATA Disk Array Systems Summary of RAID Levels The following table summarizes the performance characteristics of each RAID level. A high availability or access rate number indicates high availability or quick access rate. Array Access Capacity Availability... -

Page 23: Installing Disks
S16 Serial ATA Disk Array Systems Installing Disks This section describes how to install disks in the disk array system. Read “Understanding RAID” on page 3 to decide how many disks are required. 1 Unlock the disk tray. 2 Pull the disk tray handle to the open position. - Page 24 S16 Serial ATA Disk Array Systems 4 Insert the disk into the disk tray. The disk should face up with the connectors directed toward the open rear of the tray. 5 Align the rear of the disk with the rear of the disk tray.
- Page 25 S16 Serial ATA Disk Array Systems 8 Push the disk tray handle closed. 9 Lock the disk tray. 10 Repeat steps 1 to 9 until all of the required disks have been installed.

Page 26: Making Connections
S16 Serial ATA Disk Array Systems Making Connections After the required number of disks have been installed, external connections to the disk array system must be made. This section describes how to make all of the necessary connections. Connecting the Host Interface The disk array system has either dual SCSI interfaces or dual fibre channel interfaces. -
Page 27: Connecting The Rs-232 Cable
S16 Serial ATA Disk Array Systems Fibre Channel Interface The ERX16S-F2R4 has dual 2 Gbit fibre channel interfaces. Each interface can be used with opti- cal or copper transceivers and cables. Follow these instructions to make optical connections. 1 Insert the LC Optical SFP transceiver (A) in to the ERX16S-F2R4 host port 1 (primary fibre channel) at the rear of the disk array system. -
