Page 5: Chapter 1 Raid Introduction
RAID technology and advanced array management features. RAC281 controller connects to the host system through an SCSI interface. It can be configured to any RAID level. It provides reliable data protection for servers and offers a new technology to implement the RAID 6 function. -
Page 6: Terminology
Caution RAC281 series controller does not design SCSI terminator on system. It must add external SCSI terminators. Caution Snapshot/rollback features need 512MB RAM or more. Please refer to a certification list for RAM in Appendix A. - Page 7 users could access by using the SCSI commands. Graphic User Interface. RAID width, copy and row are used to describe one VG. RAID width, RAID copy, E.g.: RAID row One 4-disk RAID 0 volume: RAID width= 4; RAID (RAID cell in copy=1;...

Page 8: Raid Levels
MPIO Multi-Path Input/Output. SAF-TE SCSI Accessed Fault-Tolerant Enclosures. 1.3 RAID levels Describe RAID levels as follows: Disk striping. RAID 0 needs at least one hard drive. RAID 0 Disk mirroring over two disks. RAID 1 needs at least two hard RAID 1 drives. -

Page 16: Quick Install
3.3 Quick install It is easy to use “Quick install” function to create a volume. Depend on how many physical disks or how many residual spaces on created VGs are free, the system will calculate maximum spaces on RAID levels 0/1/3/5/6. “Quick install” function will occupy all residual VG space for one UDV, and it has no space for snapshot. -

One shares global cache volume, the other uses dedicated cache volume. - Page 32 (Figure 3.5.7.2: Creating a RAID 5 with 4 physical disks, named “VG-R5”. The total size is 228096MB. Because of no related UDV there, free size still remains 228096MB.) Step 2: Create UDV (User Data Volume). To create a data user volume, please follow the procedures.

Striping with parity on the dedicated disk. RAID 3 allows one RAID 3 hard drive fails or plugs out. Striping with interspersed parity over the member disks. RAID RAID 5 5 allows one hard drive fails or plugs out. 2-dimensional parity protection over the member disks. RAID RAID 6 6 allows two hard drives fail or plug out. - Page 49 Double check the setting of RAID level and RAID PD slot. If no problem, click “ “. Finally a confirm page is shown with detail RAID info. If no problem, click “ “ to start migration. Migration starts and it can be seen from the “status 3” of a VG with a running square and an “M”.

(Figure 4.4.2.1: It will take snapshots every hour, and keep the last 8 snapshot copies.) Tips Daily snapshot will be taken at every 00:00. Weekly snapshot will be taken on every Monday 00:00. 4.4.3 Rollback The data in snapshot UDV can rollback to original UDV. Please follow the procedures. -
Page 55: Appendix
Check the firmware of two systems first. It’s better that both have same firmware version or newer. Whole physical disks of related VG should be moved from system-1 to system-2. The configuration of both VG and UDV will be kept but LUN configuration will be cleared to avoid conflict with system-2. -
