Page 53: Configuring A Storage Solution
Configuring a Storage Solution Chapter 6 Configuring a Storage Solution 6.1 Creating Disk Arrays Configuring a storage solution requires some planning to ensure that you define the correct RAID level and array options, hot spares and logical drives for your solution requirements. This chapter will step you through the process to configure and manage your disk arrays, assign hot spares and create the logical drives.
Page 54: Terminology
StorView RAID Module 6.1.2 Terminology The following describes some of the terminology used when creating disk array’s and logical drives. Term Description Array A group of disk drives that are combined together to create a single large storage area. Up to 64 arrays are supported, each containing up to 16 drives per array.
Page 55 Configuring a Storage Solution Term Description RAID Level 1 RAID 1 is defined as disk mirroring where one drive is an exact copy of the other. RAID 1 is useful for building a fault-tolerant system or data volume, providing excellent availability without sacrificing performance.
Page 56: Optimization And Drive Selection For Raid 5 And 6
StorView RAID Module 6.1.3 Optimization and Drive Selection for RAID 5 and 6 Typical RAID 5 or 6 implementations require a number of steps to write the data to the drives. In order to optimize your system performance based on the type of writes you expect in your operation, we have provided detailed information on optimizing the performance using full strip write operations in an appendix.

Page 186: Access Statistics
StorView RAID Module 15.2 Access Statistics These statistics are for both reads and writes, and can be used to tune the operating system for optimum performance. Figure 15–1 Statistics Screen - Access Tab Every time statistics are viewed, the controller first outputs the time since the statistics were last reset. However, the statistics can be cleared at any time.
Page 187: Command Size - Alignment Statistics
Statistics 15.3 Command Size - Alignment Statistics Command size statistics express the percentage of commands whose size is as specified. The Alignment statistics is the percentage of commands whose address aligned on the specified address boundary. Figure 15–2 Statistics Screen - Command Size/Alignments Tab Statistic Description Command Size...
Page 188 StorView RAID Module Statistic Description How to Use Command Size and To calculate the alignment, we check the LBA for the largest Alignment number of blocks that will evenly divide into it, in powers of 2. So, we can see that in this case, the alignment is 0x10 = 16 blocks.
Page 189: Read-Ahead Statistics
Statistics 15.4 Read-Ahead Statistics If sequential read commands are sent to the controller, it assumes that the commands which follow may also be sequential. It can then go and perform a read of the data, before the host requests it. This improves performance, particularly for smaller reads.
Page 190 StorView RAID Module Statistic Description Read-Ahead Command Hit Rate This is the percentage of read command hits versus the total number of read commands that have been issued. This gives an indication of the sequential nature of the data access pattern from the host.
Page 191: Command Cluster Statistics
Statistics 15.5 Command Cluster Statistics To increase performance, the controller can cluster sequential write commands together to create a larger write command. This results in less commands being sent to the disk drives. Additionally, if sufficient data is clustered by the controller, then it can perform a a full stripe write for RAID5/50/6 arrays. This significantly improves performance.
Page 192 StorView RAID Module Statistic Description Command Cluster Interval In determining whether to cluster write commands or not, the controller will search back in the command queue whenever it receives a new write command. In a multi threaded operating system, commands from each thread may be interspersed with commands from another thread.
Page 193: A Optimizing Write Performance
Optimizing Write Performance Appendix A Optimizing Write Performance A.1 Introduction With a typical RAID 5 implementation, there are a number of steps that are performed when data is written to the media. Every write from the host system will typically generate two XOR operations and their associated data transfers, to two drives.
Page 194: Sequential Access
StorView RAID Module Maximum performance will be achieved when all drives are performing multiple commands in parallel. To take advantage of a Full Stripe Write, the host has to send enough data to the controller. This can be accomplished in two ways. First, if the host sends one command with sufficient data to fill a stripe, then the controller can perform a Full Stripe Write.
Page 195: Sub-Array
Optimizing Write Performance Figure A–2 Distribution of Data and Parity in a RAID 5 with Eight Drives In the figure on the previous page, we can see that seven chunks of sequential data are necessary to fill a stripe. To have multiple commands active for all disk drives, this requires more data than for the case with five drives.
Page 196: Multiple Drive Failures
StorView RAID Module It can be seen that the more sub-arrays used, the more likely it is for a Full Stripe Write to occur, and hence the higher the performance. It is recommended to use either four or five drives in a sub-array, for best performance.

Page 203: C More On Snapshot
More on Snapshot Appendix C More on Snapshot C.1 Overview This appendix is provided to give a more in depth look at Snapshot, in order to provide a better understanding of the technology used. The Snapshot engine has been designed to give the user considerable flexibility when setting up and performing snapshot and snapback operations.
Page 204: Overwrite Data Area
StorView RAID Module Term Description Overwrite Data Area, ODA An internal storage area on an array that is dedicated to storing data from a snapshotted logical drive. The data stored on the ODA is the data from the logical drive that needed to be overwritten after a snapshot was initiated.
Page 205: Overwrite Data Area Location
More on Snapshot C.3 Overwrite Data Area Location The overwrite data areas can be configured in two different ways. On the same disk array as a regular logical drive or on one or more separate disk arrays dedicated for the use of ODAs. If the ODA area is located on the same physical disk array as the logical drive being snapshotted, the performance of both reads and writes to the logical drive will be affected.

If the Overwrite Data Area does get filled to its limit and can no longer store copy-on-write data, the Snapshot will become out of phase with the underlying snapshotted logical drive resulting in all Snapshots for this logical drive being invalidated by the RAID Controller.
Page 207: Operating System Cache
More on Snapshot C.7.2 Operating System Cache The second highest level of caching disk data is provided by the operating system (OS). The OS will dedicate a large percentage of its DRAM space to be used for disk data caching. It is required to ask the OS to flush its entire disk cache just before the snapshot is issued.
