Chapter 1. Introduction
Overview
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.
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,intheProduct family field, select Disk systems.

Best practices guidelines
To ensure optimal operation of your system, always follow these best practices
guidelines:
v Make sure that the storage subsystem is in an optimal state before you shut it
down. Never turn off the power if any amber LED is lit; be sure to resolve any
error conditions before you shut down the storage subsystem.
v Back up the data on your storage drives periodically.
v To maintain power redundancy, connect the DS3300 right and left power-supply
units to two independent external power circuits through ac power distribution
units (PDUs) inside a rack cabinet or directly into external receptacles. Similarly,
the right and left power supplies of the storage expansion enclosures (such as
the EXP3000) that are attached to the DS3300 should be connected to the same
two independent external power circuits as the DS3300. This ensures that the
DS3300 and all its attached storage expansion enclosures will have power in the
event that only one power circuit is available. In addition, having all the right or
all the left power cables connected to the same power circuit enables the
DS3000 devices in the configuration to power-on simultaneously during an
unattended restoration of power.
Note: Do not overload the circuits that power your storage subsystem and
storage expansion enclosures. Use additional pairs of ac PDUs. See
Table 1 on page 4 for information about storage subsystem power
requirements. Contact your technical-support representative for additional
information.
v Before any planned system shutdown or after any system additions, removals, or
modifications (including firmware updates, logical drive creations, storage
partitioning definitions, hardware changes, and so on), save the storage
subsystem profile as explained in the DS3000 Storage Manager Version 2
Installation and User's Guide for your operating system. Save the profile in a
location other than in the logical drives that are created for the DS3300.
v During any maintenance or attended power-on procedure, carefully follow the
power-on sequence that is described in “Turning on the storage subsystem” on
page 44. Make sure that each component of the storage subsystem is
powered-on in the correct order during this entire power-on procedure to make
sure that the controller will be able to optimally access all of the storage
subsystems.
v The storage subsystem supports simultaneous power-on to the system
components; however, you should always follow the power-on sequence that is
described in “Turning on the storage subsystem” on page 44 during any attended
power-on procedure.
v A storage subsystem in an optimal state should recover automatically from an
unexpected shutdown and unattended simultaneous restoration of power to

system components. After power is restored, call your IBM technical-support
representative if any of the following conditions occur:
– The storage subsystem logical drives and subsystems are not displayed in the
DS3000 Storage Manager Version 2 graphical user interface.
– The storage subsystem logical drives and subsystems do not come online.
– The storage subsystem logical drives and subsystems seem to be degraded.
Storage subsystem components
The storage subsystem has the following removable components. These
components, called customer replaceable units (CRUs), are accessible from the
front or rear of the storage subsystem.
v Up to twelve 3 Gbps SAS or SATA hard disk drives
v Up to two RAID controllers
v Two power supplies
Disk drives and bezels
Figure 2 shows the locations of hot-swap disk drives and bezels. The hot-swap
features enable you to remove and replace hard disk drives, power supplies, and
controllers (in a dual-controller storage subsystem) without turning off the storage
subsystem. You can maintain the availability of the storage subsystem while you
remove, install, or replace a hot-swap device.
The hot-swap drive bays that are accessible from the front of the storage
subsystem are shown in Figure 2.

You can install up to 12 hot-swap SAS or SATA hard disk drives in the
DS33000.
Filler panel
The DS3300 comes with filler panels in the drive bays. Before you install a
hard disk drive, remove the filler panel and save it for future use. Each of
the 12 drive bays must contain either a filler panel or a hard disk drive.

The DS3300 supports up to twelve 3 Gbps SAS or SATA hard disk drives, which
come preinstalled in drive trays. Install drives in the 12 drive bays on the front of
the storage subsystem. When a drive is installed, the drive and tray bay designation
is set automatically. The hardware addresses are based on the enclosure ID setting
on the controller and on the physical locations of the drives in the storage
subsystem.
There are no serviceable parts in a drive assembly. If it fails, it must be replaced in
its entirety (drive, bezel, and tray). When you replace a drive, be sure to order and
install the correct drive. Using a nonsupported drive causes the drive to be locked
out by the DS3300 controller firmware.

Controllers
Attention:
1. After you remove a drive from a bay, wait 70 seconds to allow the drive to spin
down before you replace or reseat the drive. Failure to do so might cause
unpredictable results.
2. Never hot-swap a drive when its associated green activity LED is flashing or its
associated amber fault LED is flashing. Hot-swap a drive only when its
associated amber fault LED is lit continuously or when the drive is inactive and
its associated green activity LED is not flashing.
Note: If the hard disk drive that you want to remove is not in a failed or bypass
state, always use the Storage Manager software either to place the drive in a
failed state or to place the array that is associated with the drive (or drives)
in an offline state before you remove the drive from the enclosure.
The DS3300 has one or two hot-swappable and redundant RAID controllers. The
controllers are at the rear of the storage subsystem. The left controller is controller
A, and the right controller is controller B. When the DS3300 has two controllers,
one controller will continue to operate if the other controller fails.
The controllers contain the storage subsystem control logic, interface ports, two
gigabyte iSCSI data ports, and LEDs.
Each controller has one drive expansion port for connecting to the DS3000 storage
expansion enclosures and one Ethernet port for DS3300 subsystem management
purposes. See Figure 13 on page 23 and Figure 20 on page 34.
Attention: When a DS3300 has two controllers, the controllers must be identical
to each other in hardware (part number, DIMM size) and firmware.
The storage management software automatically sets the enclosure ID number for
the controllers. You can change the enclosure ID setting through the DS3000
storage management software only. There are no switches on the DS3300 chassis
to manually set the enclosure ID. Both controller enclosure ID numbers are identical
under normal operating conditions.

Power supply and fans
The storage subsystem has two removable power-supply units. Each power-supply
unit contains one power supply and two fans. The four fans pull air through the
drives from front to back across the drives.
The fans provide redundant cooling, which means that if one of the fans in either
fan housing fails, the remaining fans continue to provide sufficient cooling to
operate the storage subsystem. The power supplies provide power to the internal
components by converting incoming ac voltage to dc voltage. If one power supply is
turned off or malfunctions, the other power supply maintains electrical power to the
storage subsystem. To preserve the optimal airflow, do not remove a failed
power-supply unit from the DS3300 chassis until you are ready to replace it with a
new power-supply unit.

Each RAID controller contains 512 MB of cache memory (or more, if you have
upgraded the memory). It also contains a sealed, rechargeable lithium ion battery
that maintains data in the cache for up to 3 days in the event of a power failure.
Figure 9 shows the locations of the battery and memory cache DIMM in the
controller.

The battery chargers in the power supplies perform a battery test when the storage
subsystem is started and on a regularly scheduled interval thereafter. Data caching
starts after the battery tests are completed.
The condition of the battery is indicated by an LED on the rear of the controller (see
“Controller LEDs” on page 52 for the location of the battery fault LED and
conditions that the LED indicates).
Software and hardware compatibility and upgrades
The latest DS3300 controller firmware and NVSRAM, the storage expansion
enclosure (drive enclosure) ESM firmware, and the hard disk drive firmware must
be installed to ensure optimal functionality, manageability, and reliability.

Determining firmware levels
To determine the firmware levels of the DS3300 storage subsystem, the connected
storage expansion enclosures, and the installed hard disk drives, use the DS3000
Storage Manager software that is used to manage the DS3300 storage subsystem.
In the Subsystem Management window, click the Summary tab; then, click Storage
Subsystem Profile in the Hardware Components section. When the Storage
Subsystem Profile window opens, click the All tab and scroll through the Profile
For Storage Subsystem to locate the following information.
Note: The Profile For Storage Subsystem contains all the profile information for
the entire subsystem. Therefore, you might have to scroll through a large
amount of information to locate the firmware version numbers.
