Chapter 1 Storage Overview (2) Logical configuration of a disk array In a disk array, put multiple physical disks together to set up a virtual medium to compose RAID, and partition the space in the virtual medium to make logical disks. Data on the logical disks is stored into the areas of physical disk associated with the partitions on the virtual medium in which the logical disks are composed.
Chapter 1 Storage Overview Dynamic pool The dynamic pool is a virtual medium, which manages the space on the pool using a virtual storage space. Like block management in a file system, the dynamic pool manages used space and unused space. When making up logical disks, separate unused space from the pool according to the required capacity, then assign the physical disk space corresponding to the logical disk space.
Chapter 1 Storage Overview • RANK Other than disk arrays with pool In the disk arrays indicated above, multiple physical disks put together to make up a virtual medium for RAID is called RANK. Areas on RANK are controlled by using a continuous address space. The logical disks usually belong to one RANK, and a continuous space on one RANK is assigned to them.
Chapter 2 Overview of Disk Array Configuration Setting Chapter 2 Overview of Disk Array Configuration Setting This chapter describes an overview of the disk array configuration setting. The disk array configuration setting is a function for setting the configuration when initializing the disk array and when extending the physical disks. This operation can be performed by using a GUI from the iSM client.

Data on the logical disks is stored into the areas of physical disk associated with the partitions on the virtual medium in which the logical disks are composed.
Chapter 2 Overview of Disk Array Configuration Setting 22..11..11 B Baassiicc P Pooooll The basic pool is a virtual medium, which manages the space on the pool using a continuous address space. As you handle logical disks on RANK, assign the continuous space on the pool to the logical disks. In addition, like a multi-RANK configuration, the basic pool supports a striping configuration for distributing and storing data into multiple RAID configurations.
Chapter 2 Overview of Disk Array Configuration Setting 22..11..22 D Dyynnaam miicc P Pooooll The dynamic pool is a virtual medium, which manages the space on the pool using a virtual storage space. Like block management in a file system, the dynamic pool manages used space and unused space. When making up logical disks, separate unused space from the pool according to the required capacity, then assign the physical disk space corresponding to the logical disk space.
Chapter 2 Overview of Disk Array Configuration Setting Server Add physical disks one by one as required to the pool to expand the available space. Logical Disk Create a new logical disk. Expand the existing logical disk capacity, keeping the current data. Physical Disk Pool Put back a logical disk no longer needed to the pool.
Chapter 2 Overview of Disk Array Configuration Setting (1) You can bind a dynamic pool: You can bind a virtual storage space, or a dynamic pool, by selecting a set of unused physical disks on the disk array. The RAID type usable and the number of physical disks required for a dynamic pool are fixed. Select either of the following two types of RAID6 configuration according to the number of physical disks required.
Chapter 2 Overview of Disk Array Configuration Setting For details on how to expand a dynamic pool, refer to 7.1.2 “Expanding Capacity of a Pool” in Part IV “Operations”. Additional Physical Disks Configuration 1 to 5 RAID6 (4+PQ) 1 to 9 RAID6 (8+PQ) 6 or more RAID6 (4+PQ) 10 or more RAID6 (8+PQ) Rebuild after Expansion of Pool The pool is rebound. Rebinding the pool influences access to the existing logical disks which belong to the pool.
Chapter 2 Overview of Disk Array Configuration Setting 22..11..33 R RA AN NK K The logical disks usually belong to one RANK, and a continuous space on one RANK is assigned to them. In a multi-RANK configuration, the logical disks belong to multiple RANKs, and continuous spaces on the multiple RANKs are assigned to them.

Chapter 2 Overview of Disk Array Configuration Setting 22..22 L Lo og giiccaall D Diisskk The logical disks in the disk array are equivalent to the physical disk when viewed from the OS. the OS, this physical disk is partitioned to be managed as multiple logical disks. In In the disk array, multiple physical disks are bound as a pool or RANK, which is then divided to form logical disks.
Chapter 2 Overview of Disk Array Configuration Setting 22..33 S Sp paarree When binding pools or RANKs other than RAID0, data are still in the disks even when a single physical disk (two physical disks for RAID6) fail(s). However, if one more physical disk fails, data may be in danger of being lost. To cope with this situation, the reliability of the disk array can be enhanced further by switching to a reserve (i.e. Spare) disk which is set beforehand, at the point when a physical disk fails.
Chapter 2 Overview of Disk Array Configuration Setting Before operating the disk array, users can perform efficient management of the disk array by setting the ID information with the nickname.
Chapter 3 Overview of AccessControl Chapter 3 Overview of AccessControl This section describes functions available when program product “AccessControl” is purchased. The AccessControl is optional software. The AccessControl provides functions to set and unset information on accessibility from the business server to logical disks. Using these functions enables users to easily and flexibly change configuration of logical disks and perform accessibility setting.
Chapter 3 Overview of AccessControl 33..11 L LD DS Seett The concept of “LD Set” is introduced to Access Control. The concept of LD Set enables to assign logical disks collectively to ports of multiple disk arrays and WWNs. When one single business server has multiple access paths and if its I/O paths are duplicated or it is clustered, define multiple access paths together by using an LD Set. For ports and WWNs defined as paths of an identical LD Set, Access Control can be collectively set.

Chapter 3 Overview of AccessControl • Business server C can access logical disks LD04 and LD0a. • LD05 and LD0b cannot be accessed from any business server. This function can divide the logical disks which bind the disk array into logical disk groups in terms of each business server HBA (Host Bus Adaptor). It can also restrict the access in terms of each server, thus making possible data protection and security protection, etc.

Chapter 3 Overview of AccessControl • Business server C can access logical disks LD04 and LD0a through port Port3. • LD05 and LD0b cannot be accessed from any business server. This function can divide the logical disks which bind the disk array into logical disk groups and set whether to restrict the access or not in terms of each port. Data protection and security protection, etc. in terms of each business server connected to the port can be achieved through this function.

Appendix C RAID Appendix C RAID C C..11 R RA AIID D The word RAID was first introduced in the thesis “A Case for Redundant Arrays of Inexpensive Disks” released by professors of the University of California at Berkeley of the U.S.A. in 1987. The initials RAID of “Redundant Arrays of Inexpensive Disks” mean literally “a set of redundant and inexpensive disks”. However, RAID has been generally explained with “Inexpensive” replaced by “Independent” in these days.

If processing is performed concurrently for the physical disks of the RAID, the data transfer time is reduced to 1/(number of PDs) and data can be accessed quickly.
Appendix C RAID (2) RAID1 Data Sent from Host Block1 Block 2 Block 1 Block 2 Block 3 Block 4 Block 3 Block 4 Block 5 Block 5 Block 1 Block 2 Block 3 Block 4 Block 5 Physical Disk1 2 This method writes data (sent from the host) onto two disks (or into 2 disk groups).

Appendix D (2) Notes on Use for Data Replication Specifications common to Configuration Settings (GUI and CLI) Configuration Settings (GUI and CLI) process logical disk capacities in megabytes. According to “(1) Disk array specifications” and common specifications in combination, the capacity unit of logical disks to be bound is the lowest common multiple of “128KB × number of data disks” and “1MB (= 1024KB)” as shown in Table D-2.
Appendix D (4) Notes on Use for Data Replication Examples of obtaining capacities of LD to be bound through Individual Setting of Configuration Setting (GUI) The following are examples of capacities obtained by specifying a capacity or the number of data disks when logical disks are bound. Refer to D.3.3 “Method of Specifying Configuration Setting” for details on “Capacity Specification” and “Disk Count Specification”. Examples 1: Binding with Capacity Specification 1.
Appendix D Notes on Use for Data Replication Note that the logical disk capacity displayed by the iSM is that available to the user, not the total capacity including the disk array management area.
Appendix D Notes on Use for Data Replication D D..33..22 D Deettaaiilleedd C Coom mbbiinnaattiioonn ooff R RA AIID D C Coonnffiigguurraattiioonn This disk array series defines that the capacity unit of logical disks to be bound depends on the RAID configuration. Therefore, RV may not be bound in RAID configuration different from that of MV. Table D-3 shows the combinations of RAID configurations in which RV having the same capacity as for MV can be bound.
Appendix D Notes on Use for Data Replication D D..33..33 M Meetthhoodd ooff S Sppeecciiffyyiinngg C Coonnffiigguurraattiioonn S Seettttiinngg There are two methods (Batch Setting and Individual Setting) for binding logical disks through Configuration Setting (GUI). Each method includes another three specification methods “Disk Count Specification”, “Capacity Specification”, and “Disk Count and Capacity Specification”. There are six specification methods in total.

Appendix E Logical Disk Used Capacity When Y > 0, Pool used capacity = X + 2 + N - Y A mode N is a congruence representing the remainder of A divided by N. (2) Examples When you bind 1.0-GB logical disks with RAID10 (16 PDs): Y = (1024 + 2) mod 8 = 2 Pool used capacity = 1024 + 2 + 8 - 2 = 1032 MB When you bind 1.0-GB logical disks with RAID10 (8 PDs): Y = (1024 + 2) mod 4 = 2 Pool used capacity = 1024 + 2 + 4 - 2 = 1028 MB When you bind 1.
