The Western Digital Ultrastar Data 60 (UsD-60) is a high-density, rack-mounted storage enclosure available in a 4U form factor. It has the capacity to hold 60 drives.

Additional Documentation References

• Western Digital's documentation for the Ultrastar Data60 is available at the following location Ultrastar Data60 Hybrid Storage Platform.
• Adaptec SmartRAID documentation is available under the Documentation tab at the following location Microchip Technology.

Hardware Requirements

The UsD-60 requires the following hardware configuration:

• NetWitness Series 7
• Adaptec SmartRAID Adapter
• Mini-SAS cables

NetWitness Configuration Guidelines

Zoning: Each UsD-60 supports up to five NetWitness appliances connected simultaneously by using the Ultrastar’s zoning feature.
Cabling: Each NetWitness appliance requires at least two mini-SAS connections: a primary connection and a backup connection. When both cables are functioning properly, they are used simultaneously for communication with the UsD-60. When connecting the mini-SAS cables, make sure the cables on side A match the corresponding numbers on side B. For example, cables A1 and B1 would be connected to a single NetWitness appliance.

Warning: The Ultrastar-connected mini-SAS cable must not be attached to the NetWitness Hybrid appliance until the orchestration is complete. Connecting the cable beforehand will cause orchestration to fail.

The following figure shows the error when attempting orchestration while the Ultrastar is connected to the NetWitness Hybrid appliance.

IMPORTANT: If the Ultrastar-connected mini-SAS cable was attached before orchestration, you must disconnect the mini-SAS cable from the NetWitness Hybrid appliance and re-image the appliance to resolve the issue.

Zoning Configuration

The UsD-60 contains 60 hard drives in five columns of 12 drive physical configuration.

These drives can be divided into separate zones, ensuring that each connected NetWitness device can access only its designated zone.

Predefined Zones

NetWitness uses seven predefined zoning configurations based on files. These file-based zoning configurations must not be combined with any other zoning configuration methods. When file-based zoning is enabled, it will override all other zoning methods after a system reboot. Zone files can be downloaded from this  location NetWitness Zone Configuration on Western Digital Ultrastar 60 Download.

IMPORTANT: 
-The colors in the Disks column align with those in the Interface column, showing the connection between each disk group and its corresponding interface. Make sure the colors on the left match those on the right for each Zoning configuration.
- Each color in the Zone Configurations indicates the unique NetWitness appliances and the connections corresponding to those appliances.

Zone Configuration 0

The UsD-60 comes pre-configured from the factory with a default zone setup. This configuration allows all drives to be accessible from all interfaces on the Ultrastar.

Zone Configuration 1

This configuration uses a 1x1x1x1x1 setup and supports up to five NetWitness devices simultaneously. Each device can access only a maximum of 12 drives.

 

Zone Configuration 2

This configuration uses a 2x1x1x1 setup and supports up to four NetWitness devices simultaneously.

Zone Configuration 3

This configuration uses a 3x1x1 setup and supports up to three NetWitness devices simultaneously.

Zone Configuration 4

This configuration uses a 4x1 setup and supports up to two NetWitness devices simultaneously.

 

Zone Configuration 5

This configuration uses a 2x2x1 setup and supports up to three NetWitness devices simultaneously.

Zone Configuration 6

This configuration uses a 3x2 setup and supports up to two NetWitness devices simultaneously.

Configure Zones Commands

The WDDCS utility must be used to configure a zone. The complete list of steps is available in the zone file (File-Based Zoning) section under the User Guide - WDDCS Tool in the following location Ultrastar Data60 Hybrid Storage Platform.
