Chapter 1. Introduction
This chapter describes the operating specifications, features, and components of
the IBM
®
System Storage
™
DS3300 storage subsystem (hereafter referred to as
DS3300 or storage subsystem ).
This chapter also includes an inventory checklist and important information about
best practices guidelines and product updates for your DS3300.
Overview
The IBM System Storage DS3300 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 iSCSI host connectivity and
support for RAID levels 0, 1, 3, 5, and 6, the DS3300 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 DS3300 enclosure houses one or two RAID controllers with
up to two iSCSI data ports and one drive expansion port per controller, and up to
twelve 3 Gbps SAS or SATA hard disk drives.
The DS3300 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 DS3300 supports configurations of SAS
or SATA disks, or a combination of both types of disk drives in the same enclosure.
Advanced DS3000 storage management and copy service options are available for
the DS3300, including FlashCopy
®
and VolumeCopy.
The DS3000 Storage Manager version 10 software is also available for the
DS3300. 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 DS3300 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 DS3300
documentation. To check for updates, complete the following steps:
1. Go to http://www.ibm.com/servers/storage/support/.
2. On the “Support for System Storage and TotalStorage products” page, under
Select your product , in the Product family field, select Disk systems .
