6 RAID Basics PRIMERGY Installation Release November 2007 © Fujitsu Siemens Computers 2007 All rights reserved 6 Redundant Array of Independent Disks A way of organizing several disks to provide performance OR resilience: Tolerant to a disk failure Types of RAID: Standard: Level 0 - 5 Vendor Specific: 7 > Associated technology Hot plug Hot Spare More about RAID and RAID sizing on Student CD disk_subsystem_sizing_-_raid_controller_1.0__en_.pdf What is RAID ?

7 RAID Basics PRIMERGY Installation Release November 2007 © Fujitsu Siemens Computers 2007 All rights reserved 7 RAID Level 1+0 (10): Striped Mirrored Sets Host System Disk Array Controller (DAC) Resilience Reads Cost Writes Data Disk 1 Mirrored Disk 1 Data Disk 1

8 RAID Basics PRIMERGY Installation Release November 2007 © Fujitsu Siemens Computers 2007 All rights reserved 8 RAID Level 7: JBOD – Just a bunch of disks Host System Disk Array Controller (DAC) JBOD Just a way of declaring normal disks under a RAID controller. (May include COD information)

9 RAID Basics PRIMERGY Installation Release November 2007 © Fujitsu Siemens Computers 2007 All rights reserved 9 RAID 1E: An LSI specific Level Host System Disk Array Controller (DAC) Data Disk 1 Mirroring over more than two disks. During the “Mylex era” this was called Mylex-RAID 6, This is confusing since there is a standard RAID level called RAID6 that has a completely different function Data Disk 2 Data Disk 3 3 3 44 2 21 1

10 RAID Basics PRIMERGY Installation Release November 2007 © Fujitsu Siemens Computers 2007 All rights reserved 10 Standard O/S Support  Windows 2000/2003 includes RAID 0, 1 & 5  Netware offers RAID 0, 1, 5 & 10  Unixware offers Online Storage Manager (0, 1, 0+1 & 5)  Redhat & Suse Linux Include RAID 0, 1 & 5 Fujitsu-Siemens products  DDM, Duplex Data Manager, Includes RAID 1 w Hot-spare (Important for MS Cluster configuration ) Implications of Software RAID RAID 5/3 needs a Math Co-processor (for parity creation) RAID often not supported on System/boot Partition (Except for FSC DDM) No instant fail-over ( Except for FSC DDM) Hot-Plug Support requires HW Control Mechanism. Software RAID Support

11 RAID Basics PRIMERGY Installation Release November 2007 © Fujitsu Siemens Computers 2007 All rights reserved 11 Cache Policy Write back  Only enable with BBU or UPS Support Write Through  Does not use cache  Big Impact on Parity RAID performance Predictive cache (Read Ahead pattern matching) (for RAID disable it)  Switch off – most requests are not synchronous Cache Size Must Support BBU for a weekend. Larger cache boosts parity raid if using write back policy HW RAID
