S1400, a low-end model disk array, realizes space saving (one controller and a maximum of 15
PDs may be installed per 3U) and high availability (main components have redundancy). In
addition, it provides a function to replicate logical disks (DynamicDataReplication) in the disk
array, which enables effective backup and batch processing.
Furthermore, this version can support an additional parity disk for the high reliability RAID
(RAID6) to secure the redundancy against an error in one physical disk.
(6) 100 series

<Components identification>
In the 3000/4000 series disk array, the cabinet composed of Disk Array Controller and two or more disk
enclosures is called as “Basic Cabinet (BC)” and the cabinet that is composed of multiple disk
enclosures to be connected to basic cabinet is called as “Extended Cabinet (EC)”. The 3000/4000
series disk array can mount 10 or 15 Physical Disks (PDs) per disk enclosure, and 4 disk enclosures are
managed as 1 group (array group). Individual PD has identification number per PD management
group (PD group) that includes the above 4 array groups. Thus the combination of PD group number
and PD position number enables identifying of the physical mounting place of the PDs.
In the same way, unique identification number is assigned to other components in disk enclosure
(shown below), per controller unit, and this identification number enables components in the same disk
enclosure to be specified. But assignment of identification number depends on number of component in
disk enclosure.
The 2800 series disk array is composed of Disk Array Controller (DAC) and one or more disk
enclosures. (There has no concept of basic cabinet and extended cabinet as in the 4000 series). It
can mount 15 physical disks (PDs) per disk enclosure. Only one PD management group (PD group) is
defined in it (i.e., all physical disks belong to one PD group). There is no concept of array group.
The 2000 series disk array is composed of Disk Array Controller (DAC) and one or more disk
enclosures. (There has no concept of basic cabinet and extended cabinet as in the 4000 series). It
can mount 10 or 15 Physical Disks (PDs) per disk enclosure. PD management group (PD group) is
defined depending on the connection relation to disk array controller. (PDs connected to the same
group are defined as one PD group) There is no concept of array group.
In the 100/1000 series disk array, Disk Array Controller (DAC) and DE which are in different cabinets
in the 2000 series are put in the same cabinet. 15 Physical Disks (PDs) can be carried in Disk Array
Controller (DAC). Because there is not the concept of array group, the Physical Disks connected to
the same group are managed as one group (PD group).

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.
The virtual medium is called a pool or RANK, and it supports different logical disk configurations
depending on the disk array.
• Pool
Disk arrays with pool
*The disk arrays with pool are the following:
S400/S1400/S2400/S2800
In the disk array indicated above, multiple physical disks put together to make up a virtual
medium for RAID is called a pool. The logical disks usually belong to one pool, and the
required amount of space is assigned from the pool.
There are two types of pool available as described below. They function in different manners.
Basic pool
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.
For the practical configurations of physical disks that bind a basic pool, refer to C.3 “List of
Pool-Configurable RAID Types”.
Note that the basic pool does not allow using any additional features such as pool capacity
expansion or logical disk capacity expansion.
I-18
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. 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.
The dynamic pool moderates the limit on the number of constituent physical disks and enables
flexible configurations. In addition, the dynamic pool allows to use additional features such as
pool capacity expansion and logical disk capacity expansion. For details on the dynamic pool,
refer to 2.1.2 “Dynamic Pool”.
For the practical configurations of physical disks on a dynamic pool, refer to C.3 “List of
Pool-Configurable RAID Types”.

Figure 2-3 Logical Configuration of Disk Arrays (Dynamic Pool)
S400/S1400/S2400/S2800 disk array supports the dynamic pool function.
The dynamic pool function puts a set of physical disks on the disk array together to make up a virtual
storage pool. That is, it picks up the amount of storage required for the transaction from space unused
in the pool and bind logical disks. If the storage capacity becomes short, you can add physical disks
one by one as required and putting them into the pool to expand the unused space of the pool. The
additional unused space of the pool can be used to bind a new logical disk or expand the existing logical
disk capacity, keeping the current data. In addition, you can put back logical disks no longer needed
to the pool to extend the unused space of the pool.
Therefore, the dynamic pool function helps to manage the capacity of the storage efficiently and make a
large reduction in the cost on additional storage space. It also helps to flexibly support any
configuration changes or expansion of the storage to be done for addition of new transactions or
modification to existing transactions.

The dynamic pool function provides the following advantages:
• Reduction in the cost of storage expansion
When some additional storage space is required due to an addition of new transactions and so forth,
you can add physical disks one by one as required to bind a new logical disk or expand the logical
disk capacity at that time. This means that you can add physical disks just enough for the required
capacity only with the least additional cost.
• Better flexibility of storage configuration
If the amount of data to be handled increases and the storage capacity becomes short, you can expand
the logical disk space, keeping the existing data in the logical disks. In addition, returning logical
disks no longer needed to the pool secures the unused space of the pool which can be used for another
purpose. With these features, you can flexibly support any configuration changes of storage to be
made for modification to existing transactions or operation of existing transactions.

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. The two types of configuration have
different capacity efficiencies:
RAID6 (4+PQ): 6 or more physical disks required (capacity efficiency: 67% approx.)
RAID6 (8+PQ): 10 or more physical disks required (capacity efficiency: 80%)
For details on how to bind a dynamic pool, refer to 7.1.1 “Binding a Pool” in Part IV
“Operations”.

(120 or 240)*1
10 to 60
(120 or 240)*1
*1: The maximum number of physical disks is 60 when pools are in use.
To use 61 or more disks, you need to add physical disks by extending dynamic pools.
(2) You can expand the dynamic pool capacity:
You can expand the capacity of the dynamic pool by selecting unused physical disks on the disk
array and putting them into the dynamic pool. The capacity actually added is the capacity of the
additional physical disk(s) multiplexed by the pool capacity efficiency. You can add physical
disks one by one. Naturally, you can add multiple physical disks at one time.
Usually, expanding the dynamic pool rebuilds data on the additional physical disk(s) to keep the
redundancy of RAID. Rebuilding data puts some load to the physical disks of the dynamic pool
and influences access to the existing logical disks which belong to the pool. The additional
space becomes available after the rebuild process finishes.
However, when the number of physical disks simultaneously added to the pool is a specified
number or more, the dynamic pool is expanded and made available without the rebuild process.
The additional space is usable immediately after the physical disks are added to the pool.
The RAID configuration cannot be changed from RAID6 (4+PQ) to RAID6 (8+PQ) or vise versa.
You need to add physical disks to the pool, keeping the RAID configuration.

(3) You can bind the logical disks:
You can pick up the amount of storage required from the unused space in the dynamic pool and
bind logical disks required for it. For details on how to bind logical disks, refer to 7.2.1
“Binding Logical Disks” in Part IV, “Operations”.
(4) You can expand the logical disk capacity:
Configuration Rebuild after Expansion of Pool
The pool is rebound. Rebinding the pool influences
access to the existing logical disks which belong to
the pool. The additional space to the pool becomes
available after the rebind process finishes.
The pool is not rebound. The expansion of the pool
puts no influence on any existing logical disks which
belongs to it. The additional space to the pool
becomes available immediately after it is added.
You can pick up the amount of storage required from the unused space in the dynamic pool and
increase the existing logical disk capacity. While data stored in the logical disks is secured,
some space usable for additional logical disks is added after the existing logical disks. The way
of having the host identify the additional space depends on the platform.
For details on how to expand the logical disk capacity, refer to 7.2.2 “Expanding Capacity of
Logical Disks” in Part IV “Operations”.
Some platforms do not support expansion of logical disk capacity. For details about it, ask the
maintenance personnel. In addition, in case of an error or failure, it is recommended to make a
backup of data stored in the existing logical disks before expanding the logical disk capacity.

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.
Physical Disks
Multiple physical disks
are bound to form a
pool or RANK.

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.
Spares can be set for physical disks which are not used in pool or RANK binding, thus making it
possible to recover data to a Spare in the same PD group when a physical disk fails. When recovery to
Spares is started, the pool or RANK is rebuilt and the Spares become physical disks which comprise the
pool or RANK. The failed physical disk can be replaced without stopping the access to the disk array.
Considering the physical layout, it is normally desirable to set one spare disk per DE for the physical
disk in the rightmost slot in the DE.

Nicknames refer to any names that can be set for the disk array, the logical disk, the port, and the pool
with regard to iSM’s management target. Since the names thus set are stored in the disk array, they
are held regardless of whether iSM or a disk array is restarted or not.
(1) Disk Array Name
Refers to any ID name for iSM’s management target disk array. When the disk array is
specified with iSM, the disk array name is used.
(2) LD Name
Refers to any ID name for a logical disk in iSM’s management target disk array. When the
logical disk is specified with iSM, the LD name is used.
(3) Port Name
Refers to any ID name for a port in iSM’s management target disk array. When the port is
specified with iSM, the port name is used.
(4) Pool Name
Refers to any ID name for a pool in the iSM’s management target disk array. When the pool is
specified with iSM, the pool name is used.

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.

Logical disk groups hidden from the business server by using the AccessControl function exist in this area.
This area is called Preserve Group.
[Preserve Group] Logical disks hidden from the business server and inaccessible exist in this area. Contents of
the logical disks are retained and existing logical disks include logical disks with no special purpose settings,
logical disks set in pairs for replication (MV, RV), volume for snapshots (BV), and link-volume (LV).
y [Accessible area]
Logical disk groups accessible from the business server by using the AccessControl function exist in this area.
Contents of the logical disks depend on the business server, and existing logical disks include ordinary logical
disks with no special purpose settings, replication volume (MV, RV), volume for snapshots (BV), and
link-volume (LV). In addition, each logical disk is assigned to an LD Set.

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.
That is, when you add or remove an LD Set after setting up Access Control, you can collectively handle
ports and WWNs with an LD Set specified.
When a disk array with the program product AccessControl(WWN) applied is in use, only WWNs can
be defined as paths of LD Sets.

Set level 1 to 3 as a user level. The following shows target users and executable functions at each level:
• Level 1 (L1):
This level is defined for general users. The users are permitted to perform only reference operation focusing on
status display or monitoring.
• Level 2 (L2):
This level is defined for operators. The operators are permitted to perform the level 1 operations and execute
functions necessary for daily operations.
• Level 3 (L3):
This level is defined for system administrators. The system administrators are permitted to execute all functions
including various settings for disk arrays.
After connection to the iSM server, the user level is displayed on the status bar of the iSM client. Each user can use
the functions allowed for the indicated level only.

Specify the physical disks of the disk array to be put in the RAID configuration and assign the RAID type to bind a
pool. Then, bind the logical disks to the pool to bind the logical disks. In addition, bind a control volume
individually. A control volume is a volume for control over snapshot operation. (For the details of control volumes,
refer to "Snapshot User’s Manual (Function Guide)" (IS030).)
After adding physical disks, take the steps stated above to the added physical disks to bind the logical disks. Adding
physical disks puts no influence on any existing logical disks, which belongs to the pool and already in use. Adding
and binding logical disks to the pool also puts no influence on any existing logical disks.
Pools are classified into two types; the dynamic pool allows expanding the capacity of the pool and the logical disks,
and the basic pool does not allow expanding the capacity of the pool and the logical disks.
The logical disk configurations selectable by the pool are as follows:
Logical disk configuration: Dynamic pool RAID6 (4+PQ)/(8+PQ)
Basic pool RAID1 (1+1)
Basic pool RAID5 (4+P)
Basic pool RAID10 (1+1) × 2/(1+1) × 4/(1+1) x 8
Basic pool RAID50 (4+P) × 2/(4+P) × 4
Bind logical disks in accordance with the following procedure.

With Pool rebuilding: Allows expanding the capacity of the pool without any restriction on the
number of the logical disks, in a relatively longer time.
Specify Expansion Time: Allows specifying the duration of time to expand the all physical disks only
when you specified “With Pool Rebuilding”. Although specifying 0 expands
the capacity in the shortest time, select an appropriate time taking account of
the load to the host I/O. The time specified in the field is just a target, thus it is
not assured to take the specified time.
Selection PD for Expansion
Unused PDs: Lists disks still unused.
Pool PDs: List of disks that will compose the pool after expansion
Number of Adding PDs: Number of physical disks to be added to the pool
[Add] button: Select unused physical disks to use for the pool in the “Unused PD” list, then click this
button to add them to the pool.
[Delete] button: Select any physical disks to be removed from the pool in the “to Pool” list, then click this
button. The selected physical disks are restored to the list of unused physical disks.
* It is not allowed to select any physical disks already put in the other pools.
Clicking the [OK] button displays a confirmation to ask whether you want to expand the capacity of the pool.

Specify the duration of time to do rebuild if a physical disk becomes faulty in the disk
array. You can specify 0 to 24 hours. Although specifying 0 rebuilds the faulty disk in
the shortest time, select an appropriate time taking account of the load to the host I/O.
The time specified in the field is just a target, thus it is not assured to take the specified
time.

Chapter 7 Disk Array Configuration Setting
Expansion Time: Specify the duration of time to expand the (Only Dynamic Pool) pool.
You can specify the duration of time to expand the physical disks added to the pool.
Although specifying 0 expands the pool in the shortest time, select an appropriate time
taking account of the load to the host I/O. The time specified in the field is just a target,
thus it is not assured to take the specified time.
5. Put a checkmark on the item you want to change, then specify the time.

Bind logical disks of the disk array in accordance with the following procedure in terms of each PD group.
(1) Spare Bind
It is necessary to set Spares in accordance with their applications. For information on Spares, refer to 2.3 “Spare”.
(2) Pool/RANK Bind
After considering the RAID characteristics, bind the RAID type pools suitable to the application.
Refer to Appendix C “RAID” for the types of RAID.
In pool or RANK binding, pay attention to the fact that the maximum capacity of the logical disk is less than the
pool or RANK capacity.
(3) LD Bind
Bind the logical disk with the most suitable capacity in accordance with its application. It is impossible to set a
pair unless the logical disk capacity is the same; therefore, when using data replications, it is necessary to bind
logical disks of the same capacity beforehand.
