Chapter 1. Introduction

This chapter describes the operating specifications, features, and components of the IBM® System StorageDS3200 storage subsystem (hereafter referred to as DS3200 or storage subsystem).

This chapter also includes an inventory checklist and important information about best practices guidelines and product updates for your DS3200.

Overview

The IBM System Storage DS3200 storage subsystem is designed to provide solutions to meet the needs of departmental and midrange storage requirements, delivering high performance and availability, advanced functionality, along with a modular and scalable storage capacity design. With direct-attached Serial Attached SCSI (SAS) connectivity and support for RAID levels 0, 1, 3, 5, and 6, the DS3200 provides an internal physical storage capacity that is scalable up to 5.4 TB (terabytes) when using 450 GB Serial Attached SCSI (SAS) hard disk drives or up to 12.0 TB (terabytes) when using 1000 GB Serial Advanced Technology Attachment (SATA) hard disk drives.

Notes:

1.RAID 6 uses a P+Q design implementation.

2.When RAID level 1 is implemented and the number of hard disk drives increases to more than two, RAID level 10 is automatically implemented.

A 2U rack-mountable DS3200 enclosure houses one or two RAID controllers with up to four SAS ports per controller for attachment of host servers and storage expansion enclosures and up to twelve 3 Gbps SAS or SATA hard disk drives.

The DS3200 supports attachment of up to three storage expansion enclosures, resulting in the capability to connect to up to 48 hard disk drives and enabling storage configurations of over 21 TB using 450 GB SAS hard disk drives or 48 TB using 1000 GB SATA hard disk drives. The DS3200 supports configurations of SAS or SATA disks, or a combination of both types of hard disk drives in the same enclosure. Advanced DS3000 storage management and copy service options are available for the DS3200, including FlashCopy® and VolumeCopy.

The DS3200 supports up to three hosts in a redundant direct-attached SAS configuration.

The DS3000 Storage Manager version 10 software is also available for the DS3200. This storage-management software is designed to help centralize storage management, help simplify partitioning of the DS3000 series storage into as many as 32 virtual servers, and strategically allocate storage capacity to maximize storage space.

If firmware and documentation updates are available, you can download them from the IBM Web site. The DS3200 might have features that are not described in the documentation that comes with the unit, and the documentation might be updated occasionally to include information about those features, or technical updates might be available to provide additional information that is not included in the DS3200 documentation.
