Chapter 1

Overview

This chapter provides an overview of the ETERNUS2000 features, and specifications.

1.1 System Features

Special features of the ETERNUS2000 are shown below:

■ Space and Energy Savings

• Compact design to make effective use of rack space

• There are two models available; ETERNUS2000 model 100 and ETERNUS2000 model

200. Both models are designed to be 2U size at the minimum

(*1)

. Up to 12 disk drives and

up to 12TB disk capacity

(*2)

can be installed.

•2U

(*1)

of drive enclosure can be expanded in the ETERNUS2000 models 100 and 200.

ETERNUS2000 model 200 allows up to 120 disk drives and 120TB as the disk capacity

(*2)

*1: 2U indicates the device height that can be installed in two units of 19-inch rack (88mm). *2: Physical capacity is calculated based on the assumption 1,000GB = 1TB (including Hot Spare Disks).

• Energy savings by the latest technology

Using the latest 1-chip RAID controller that is configured by multiple chips and reducing number of components allows energy savings.

• ECO mode to reduce environmental load

Using the ECO mode function to start and stop the spindle rotation in the disk drive for each RAID group during the specified hour. Stop the spindle rotation when there is no access to the disk drive to reduce power consumption and decreases environmental load.

■ Easy Installation

• Easy setup

The ETERNUS2000 can be configured easily using a web browser. When installing the ETERNUS2000, follow the setup wizard and just input parameters for displayed setting items to create RAID groups and volumes, and assign to the server.

1.1 System Features

ETERNUS2000 disk storage system User Guide P3AM-2512-03EN

■ High scalability and versatile connectivity

• Utilizes the latest disk technology

ETERNUS2000 utilizes the SAS disk drives

(*1)

(450GB/300GB/146GB (15,000rpm), 400GB

(10,000rpm)).

Also, ETERNUS2000 supports large capacity / cost effective Nearline SAS disk drives

(*1)

(1TB/

750GB/500GB (7,200rpm)) for data backup and archiving.

*1: SAS: Serial Attached SCSI

• Supports capacity expansion during system operation

• Disk drives and drive enclosures can be added during the system operation.

• RAID group capacity can be expanded by adding disk drive from the unit of one.

• Volume can be expanded during the system operation. Even when the work load increased rapidly, ETERNUS2000 flexibly expand the volume capacity with no interruption of the operation.

• High connectivity supports the multi-platform environment

• ETERNUS2000 supports FC-SAN, IP-SAN, or DAS environment by utilizing the Fibre Channel interface (maximum transfer speed: 4Gbps), iSCSI interface (maximum transfer speed: 1Gbps), or SAS interface (maximum transfer speed: 3Gbps) as the host interface.

• ETERNUS2000 supports multiple Operating Systems such as UNIX, Linux, and Windows®, and can be connected as a storage system for PRIMEQUEST, SPARC Enterprise, and PRIMERGY servers as well as for UNIX/IA servers of other companies. Also the RAID aggregation using SAN (Storage Area Network) is available.

■ Data integrity with high-speed backup

• Nearline SAS disk drives for data backup and archiving

• Using large capacity / cost effective Nearline SAS disk drives allows low cost D2D (Disk to Disk) backup and high-speed recovery in the case of unexpected failure.

• Storing the less frequently accessed data such as archive data in the Nearline SAS disk drives allows easy reading. Nearline SAS disk drives and SAS disk drives can be installed in the same drive enclosure.

• Various backup function

Cooperation between the Advanced Copy function for ETERNUS2000 models 100 and 200 (Optional), and the high-speed backup replication software "ETERNUS SF AdvancedCopy Manager" allows OPC (One Point Copy), the high-speed copying of disk volumes at specified times.

P3AM-2512-03EN ETERNUS2000 disk storage system User Guide

■ High reliability supports 24/7/365 operation

• Duplication of important components

Important components such as controllers, power supply units, and fans are duplicated to continue the operation in the case of unexpected failure. Also this allows the hot swapping of failed components with the device power on. In addition, the latest firmware can be applied during system operation.

• RAID6 responds to the double failure of disk drives

ETERNUS2000 supports RAID6, using two parity disks in one RAID group. RAID6 ensures the data safety in the unlikely case of a fatal second malfunction within a single RAID group. Also the ETERNUS2000 supports RAID1, RAID1+0, and RAID5 to realize the flexible RAID configuration.

• Redundant copy ensures disk drive redundancy

ETERNUS2000 diagnoses the disk drives to detect the failure prediction. When the disk drive requires preventive maintenance, ETERNUS2000 automatically copies the data in the target disk drive to ensure data redundancy.

• Block Guard ensures data integrity

ETERNUS2000 adds check codes and check them at multiple checkpoints on data transfer path to ensure the data integrity.

1.2 Configuration

1.2 Configuration

This chapter describes items to be noted before configuring the ETERNUS2000 systems.

1.2.1 RAID Level

This section describes the supported RAID level and usage (RAID level selection criteria), and RAID group configuration.

■ Supported RAID levels and mechanism

ETERNUS2000 supports the following RAID levels.

• RAID0 (striping)

• RAID1 (mirroring)

• RAID1+0 (striping of pairs of disks for mirroring)

• RAID5 (striping with distributed parity blocks)

• RAID6 (striping with distributed double parity blocks) (*1)

*1: RAID6 ensures data safety and continues system operation in the case of a second malfunction within a

single RAID group. RAID6 redundancy allows high availability system operation.

Each RAID level description is shown below.

CAUTIO

Remember that a RAID0 configuration is not redundant. This means that if a RAID0 disk drive fails, the data will not be recoverable. Therefore, using RAID1, RAID1+0, RAID5, or RAID6 configuration is recommended.

Chapter 1 Overview

P3AM-2512-03EN ETERNUS2000 disk storage system User Guide

• RAID0 (striping)

Data is split in unit of blocks and stored across multiple disks.

Figure 1.1 RAID0 Concept

• RAID1 (mirroring)

RAID1 stores the same data on two duplicated disks at the same time. If one disk drive fails, other disk drive continues operation.

• RAID1+0 (striping of pairs of disks for mirroring)

RAID1+0 combines the performance of RAID0 (striping) with the reliability of RAID1 (mirroring).

Figure 1.3 RAID1+0 Concept

• RAID5 (striping with distributed parity)

Data is allocated in units of blocks across multiple disks to duplicate data.
