User Guide 1. Overview
1.1 Ultrastar Data102 Description
1.1 Ultrastar Data102 Description
Figure 2: Ultrastar Data102
The Ultrastar Data102 is a 4U form factor, high availability, high density, rack-mounted storage enclosure.
It is capable of hosting up to 102 HDD drives (SAS or SATA). The maximum data storage capacity of the
Ultrastar Data102 is 2.0PB using 20TB Ultrastar HC650 drives . (For a full list of compatible drives and total
storage capacities, see the List of Compatible Drives (page 24).) The enclosure runs on an input voltage
of 200-240 VAC and consumes ~1300W of power under typical conditions. It requires a maximum of
1600W (Delta PSU) / 1800W (Artesyn PSU) at full load.
It is designed to fit within a 4U rack space and requires 1181-1197 mm (46.5in. - 47.13in.) of usable rack space,
frame to frame . A fully loaded system will add 118.8 kg / 262 lbs. of static load when fully loaded with
drives.
•4U Storage Enclosure
•Supports up to 102 Drives
•Supports 3.5” drives in the 102 available drive bays.
•Up to 12W per drive slot for the 102 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 Modules1
•Powered by two (2) redundant 1600W or 1800W 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 18))
•Supports up to 3m passive SAS cables (limited to 3m or less) or active cables (any length) (see SAS
Cabling (page 22))
1. SATA based models will only include 1 IOM

User Guide 1. Overview
1.2 System Architecture Overview
1.2 System Architecture Overview
The Ultrastar Data102 IOM uses a cascaded expander design to allow for connection to all 102 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. Each secondary
expander then connects with fifty-one (51) 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 102 data storage drives.
Note: To use T10 power disable, the drives installed must also support this feature.
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 Data102 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.
