Figure 2: Ultrastar Data60
1. Overview
1.1 Ultrastar Data60 Description
The Ultrastar Data60 is a 4U form factor, high availability, high density, rack-mounted storage enclosure
that is capable of hosting up to 60 SAS or SATA drives. The maximum data storage capacity of the Ultrastar
Data60 is 840 TB using 14TB HGST Ultrastar® HC530 drives . (For a full list of compatible drives and total
storage capacities, see the List of Compatible Drives (page 22).) The enclosure runs on an input voltage
of 200 - 240 VAC and consumes ~1000W of power under typical conditions. It requires a maximum of
~1250W at full load.
It is designed to fit within a 4U rack space and requires 900mm (35.43in.) usable rack space, frame to frame.
A fully loaded system will add 79.4 kg. / 175 lbs. of static load when fully loaded with drives.
•4U Storage Enclosure
•Supports up to 60 Drives
•Can support 3.5” drives and 2.5” SSD drives (2.5" requires an adapter) in the 60 available drive bays.
•Up to 12W per drive slot for the 60 data storage drives (Cannot exceed 85A on the 5V rail)
•House and control four (4) N+1 redundant 80mm rear fans
•House and control a dual rotor 40mm internal IOM Fan
•Controlled by two (2) redundant I/O Modules
•Powered by two (2) redundant 1600W PSUs
•Supports High Line (220-240 VAC) Input Power
•Full high availability with independent dual paths to all HDDs
•Toolless replacement of all Customer Replaceable Units (CRUs)
•Fits within a standard EIA-310 rack including all necessary cable management (see Compatible Rack
Hardware Configuration (page 17))
•Supports up to 3m passive SAS cables (limited to 3m or less) or active cables (any length) (see SAS
Cabling (page 20))

1.2 System Architecture Overview
1.SATA based models will only include 1 IOM
2
User Guide
The Ultrastar Data60 IOM uses a cascaded expander design to allow for connection to all 60 drives. A
48-port primary expander connects with the six host ports, has a x3 link to the other IOM for IOM-IOM
communication and syncing, and also has a x10 SAS link to each secondary expander. One secondary
expander then connects with fifty-one (51) drives, while the other connects with nine (9) drives.
The out-of-band management microprocessor provides an Ethernet connection using a Redfish/RESTful
API to access the various enclosure services. All the SES enclosure information can be obtained through the
out-of-band management port. Major use cases for this feature include obtaining storage subsystem health
information, locating enclosure components using the IDENT LEDs, and updating firmware.
The system FPGAs control and report the states of the system fans, enclosure LEDs, connector LEDs, drive
LEDs, and T10 drive power disable signals on the 60 data storage drives.
The I2C architecture is designed to support only one single master on any given bus. The primary expander
will be the master on each I2C bus. There are eight I2C buses used in the Ultrastar Data60 enclosure.
The number of devices on each bus are balanced to allow communication to peripheral devices and not
overload any one bus. The devices connected on the I2C buses include the enclosure VPDs, temp sensors,
baseboard FPGAs, and SAS connectors among others.

Note: To use T10 power disable, the drives installed must also support this feature.

Caution: The Ultrastar Data60 can only be plugged into high line (200 - 240 VAC) power. If
the unit is plugged into low line (110-127 VAC), the PSU will report a "Critical" state when status
pages are queried using SES. In this case, the enclosure will power up, but the drives will not.
The enclosure will remain in low-power mode.
AC line inrush current shall not exceed 40A peak, for up to
one-quarter of the AC cycle after which, the input current
should be no more than the specified maximum input current.

Function LED
Note: During service events—when a drive is hot plugged or replaced and the drive installed
properly—the LED state of that drive slot will change to solid ON. This is to provide the user
with visual feedback that the drive has been successfully connected and has been discovered
by the expander. Once the enclosure has been slid back into the rack and the OPEN bit on the
door sensor element is 0, the LED will return to the previously set state (Ident, Fault, or Off).
For example: A drive in slot 0 needs to be replaced. The fault bit on Array Slot descriptor
0 is set to indicate to the service technician which drive slot to replace. This will cause the
LED to blink at 1Hz (50% duty cycle). When the service technician pulls out the enclosure,
inserts a new drive, and successfully installs the drive, the slot LED state will change to solid
ON to indicate that the drive was properly installed. When the service technician pushes the
enclosure back into the rack and the OPEN bit of the door sensor element changes from 1
to 0, the LED state of drive slot 0 will change back to the fault indication blink rate (1 Hz 50%
duty cycle).
Blink @ 1 Hz (50% duty cycle) – Drive fault
Off – Drive has no faults
Note: LEDs have a 50% duty cycle (On for 2

User Guide
The Ultrastar Data60 is designed to be installed into a rack that meets the EIA-310 standard at a minimum
900mm (35.43in.) usable rack space, frame to frame. The vertical rack rails must be set between 24 in. 32 in. to support the enclosure. It requires 4U of rack space, and it should be installed into the rack at the
lowest possible U height to keep the load on the rack balanced.

Warning: When extended out of the rack on the rail system, the Ultrastar Data60 will be
~630mm / 24.8in. extended outward. This may be a potential tipping hazard depending on
the configuration of the rack. Ensure that leveling feet, anti-tilt, and any other safety features
recommended by the specific rack manufacturers have been deployed before servicing.
