Chapter 1 Storage Overview Chapter 1 Storage Overview This chapter describes the overview of a disk array, which is the object of the iSM management. iSM is the software for operating and maintaining the disk arrays. To understand the iSM functions and to use the iSM efficiently, first read through this chapter, then proceed to Chapter 2.
Page 11 Chapter 1 Storage Overview (4) 2000 series - S2100/S2200/S2300 S2100/S2200/S2300, mid-range disk array, realizes high scalability (up to 14 disk enclosures can be extended) and high availability (main components have redundancy). Furthermore, it provides a function to replicate logical disks (DynamicDataReplication) in the disk array, which enables effective backup and batch processing.
Page 12: Disk Array Configuration
Chapter 1 Storage Overview (1) Components The disk array is composed of Disk Array Controller (DAC), which carries the component of control systems, such as host director, disk director and cache, and Disk Enclosure (DE) that carries two or more Physical Disks controlled by DAC.

Page 26 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.
Page 27 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.
Page 28 Chapter 1 Storage Overview • RANK <Supported disk arrays> 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.

Chapter 2 Overview of Disk Array Configuration Setting 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.
Page 31: Basic Pool
Chapter 2 Overview of Disk Array Configuration Setting 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.
Page 32: Dynamic Pool
Chapter 2 Overview of Disk Array Configuration Setting 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.

Page 34 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.

Additional Configuration Rebuild after Expansion of Pool Physical Disks The pool is rebound. Rebinding the pool influences 1 to 5 RAID6 (4+PQ) access to the existing logical disks which belong to...
Page 36: Rank
Chapter 2 Overview of Disk Array Configuration Setting 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.
Page 37: Logical Disk
Chapter 2 Overview of Disk Array Configuration Setting The logical disks in the disk array are equivalent to the physical disk when viewed from the OS. In the OS, this physical disk is partitioned to be managed as multiple logical disks. In the disk array, multiple physical disks are bound as a pool or RANK, which is then divided to form logical disks.
Page 38: Spare
Chapter 2 Overview of Disk Array Configuration Setting 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.

Page 40: Chapter 3 Overview Of Accesscontrol
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.
Page 41: Ld Set
Chapter 3 Overview of AccessControl 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.

Page 266 Chapter 10 Access Control Operations Application of the New Setting invalidates all of the current assignment settings for the logical disks and new assignment settings for the logical disk immediately reflect on the Disk Array. Therefore, if setting information is wrong, the business server suddenly stops recognizing the logical disk in use.

Chapter 10 Access Control Operations When setting permission of access from the business server to logical disks, select LD Sets of a desirable business server from the tree view of the Accessible LD List display area. Then, select logical disks to be added from the [Candidate LD List] display area, and click the [Add] button.
Page 268 Chapter 10 Access Control Operations Furthermore, when selecting multiple LUNs which have not assigned logical disks, the selected LUNs must be sequential. Only a newly added logical disk group can be moved on this dialog screen. Logical disks cannot be moved to the LUN displayed as the icon.

Page 316 Appendix D 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.
Page 317 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.
Page 318: Detailed Combination Of Raid Configuration
Appendix D Notes on Use for Data Replication 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.
Page 319: Method Of Specifying Configuration Setting
Appendix D Notes on Use for Data Replication 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.
Page 320 Appendix D Notes on Use for Data Replication Table D-5 Bound LD Capacity by Specification Method Setting Capacity Specification Method How to Obtain Capacity Method Unit Disk Count Specification Divide the recommended maximum capacity*2, which is within the RANK Batch capacity, by the number of data disks.
