16 Chapter 3 System Configuration Chapter 3 System Configuration This chapter describes an overview of the system, software, and hardware of ism. * A personal computer on which Windows 2000, Windows XP, Windows Server 2003, Windows Vista, Windows Server 2008, or Windows 7 operates is referred to as a PC in this manual. Windows 2000, Windows XP, Windows Server 2003, Windows Vista, Windows Server 2008, or Windows 7 is generally referred to as Windows in this manual System Overviiew ism consists of server and client functions. The server function operates on a management server, and directly monitors the disk arrays connected through a LAN or FC (Fibre Channel). The client function operates on a PC connected with the management server through a LAN, and provides the user with the monitoring and operation functions through the GUI. In addition, the client function provides the following two GUIs: GUI based on Windows GUI based on the Web In this manual, ism client or client is used for describing the client function without separating the above two. Also, to describe the former GUI only, ism client (Win GUI) or client (Win GUI) is used, and to describe the latter GUI only, ism client (Web GUI) or client (Web GUI) is used. ism provides various functions to operate the disk arrays. Figure 3-1 shows a system configuration example using ism. 10

Storage Control Software *1 DynamicDataReplication RemoteDataReplication DynamicSnapVolume VolumeProtect AccessControl PerformanceOptimizer CachePartitioning VirtualStoragePartitioning ThinProvisioning Figure 3-1 System Configuration Example It is recommended that the management server and the disk array be connected through a LAN. They can also be connected through a fibre channel. In this case, however, if the application server is subjected to a high load, contention may occur between application I/O and performance monitoring, performance optimization, or data replication I/O. The I/O path of each server also needs to be specified in the AccessControl setting. Thus, connection through a LAN from a separate management server is safer than connection through FC. A disk array supporting iscsi can be connected with the management server only through a LAN. If connecting the management server and a disk array through a LAN, you need to set the network information (e.g., IP address) for the disk array. Set the information correctly according to the manual provided with the disk array. ism can monitor more than one disk array simultaneously. However, do not use more than one ism programs to simultaneously monitor a single disk array. If multiple ism programs are used to monitor a single disk array, a repeatedly noticed error or a conflict between their statistical information of performance may cause operation trouble. 11

(1) BaseProduct BaseProduct includes storage control software, which is responsible for the basic control of disk arrays, and the software of ism, which enables the monitoring of the basic state of disk arrays. The storage control software performs basic control such as host interface control, disk control, RAID control, logical disk control, and cache control for disk arrays. The software of ism is explained in (2) Storage Manager below. For details, refer to the NEC Storage Manager User s Manual of the OS in which the ism server is installed. BaseProduct is a program product required for operating the S series, A series, and D series disk arrays. (2) Storage Manager ism is software that enables the monitoring of the basic state of disk arrays. ism has the following functions: Centralized management of storage Manages multiple storages (up to 64) through a single control server. Storage state management and configuration management Centrally manages the storage state and configuration information, and displays the information through the GUI under Windows. Configuration setting Enables users to arbitrarily set a storage internal configuration. Users can build logical disks from physical disks through the GUI under Windows. Available functions depend on the model of the storage. For details, refer to the Configuration Setting Tool User s Manual (GUI). Error notice function 13

20 Chapter 3 System Configuration If a storage error occurs, this function sends mail and starts the program. The function enables the sending of error notices to remote maintenance persons and the customization of system-specific error management. For details, refer to the NEC Storage Manager User s Manual of your OS in use. For the S series, A series, and D series, ism is included in BaseProduct that is a program product required for operating the disk arrays. For the E series, only the summary status and basic information of the disk array are displayed. To display detailed configuration management/status monitoring/configuration settings, use NEC Storage Manager Express. NEC Storage Manager Express can be started from the ism client (Web GUI). 14

21 Chapter 3 System Configuration 3..3 Hardware This section explains the overview of the disk array, which is the managed object of the ism. Each disk array consists of a controller (DAC: Disk Array Controller) and one or more disk enclosures (DE: Disk Enclosure). The controller contains control-system components such as a host director (HD: Host Director), replication director (RD: Replication Director), disk director (DD: Disk Director), and cache module (cache module card), and controls a disk enclosure(s) in which multiple physical disks (PD: Physical Disk) are installed. A single disk enclosure can contain 10, 12, or 15 physical disks, and 4 disk enclosures are managed as an array group, although it differs depending on the disk array model. (The D series and 100/1000/2000/2800 series do not have the concept of an array group.) For details, refer to the Configuration Setting Tool User s Manual (GUI). 15

22 Chapter 3 System Configuration (1) D series In recent years, the explosive growth of the broadband increases various exchanges via the Internet and the amount of data, such as s and video contents. The most noteworthy problems about storages in IT systems are the surge in the amount of data, complexity of management, and great effect when operations are stopped. The D series, which is the next generation storage that adopts advanced virtual technology, has been developed to solve the storage problems every company might have. The D8, the scalable storage model, which enables flexible expansion of capacity up to PETA byte level, and the D1 series, D3 series, and D4 series, the high cost-performance storage models, which are intended to small- to medium-sized systems, are added to the product line. This enables to respond to user s demands for the entry class to the high end class. D8 series The D8 series has three advantages: non-disruptive scalability that enables to expand the capacity of the system which was started as a small system at the initial installation up to PETA byte level and to improve the performance linearly, manageability that creates a pool of physical resources in a storage and configures a virtual storage to which necessary resources are allocated from the pool according to the operation types, and availability that takes multiplexing and module configuration to minimize the risk of system stop due to an occurrence of a failure.

25 Chapter 3 System Configuration D3 series/d4 series The D3 series and D4 series, the low end disk array of the D series, achieve little space consuming (one controller and maximum of 12 PDs may be attached per 2U), and high availability (main components are redundant (however, except the single controller model)). Furthermore, it provides the function to replicate logical disks (DynamicDataReplication, RemoteDataReplication (only for the FC model)) in a disk array and between disk arrays, and enables effective backup and batch processing. This series provides two models that are equipped with different interface types. One is equipped with iscsi and the other is equipped with high-performance FC. For the iscsi model, an inexpensive IP-SAN (Storage Area Network) can be configured by using Ethernet equipment. The iscsi model provides a Dual Controller model and Single Controller model. The FC model provides a Dual Controller model. Adding a parity disk supports high-reliability RAID (RAID6, RAID-TM) which does not lose redundancy when an error occurs in one physical disk. D1 series The D1 series, the entry model disk array only for Windows/Linux of the D series, achieves little space consuming (one controller and maximum of 12 PDs may be attached per 2U), and high availability (main components are redundant (except the single controller model)). Furthermore, it provides the function to replicate logical disks (DynamicDataReplication) in a disk array, and enables effective backup and batch processing. This series provides two models that are equipped with different interface types. One is equipped with iscsi and the other is equipped with high-performance FC. For the iscsi model, an inexpensive IP-SAN (Storage Area Network) can be configured by using Ethernet equipment. Both the iscsi model and FC model provides a Dual Controller model and Single Controller model.
