The Lenovo

ThinkServer

™

RD120 (Machine Types 6444, 6445, 6446, and 6447)

server is a 5-U-high, high-performance server. It is ideally suited for networking

environments that require superior microprocessor performance, improved systems

management, and flexible memory and data management.

The server has two model styles, which are based on the size and number of hard

disk drive bays:

v The 3.5-inch models have six 3.5-inch hot-swap hard disk drive bays. Install only

3.5-inch drives in these models. If you intend to install an optional tape drive, the

tape drive will occupy two of the six 3.5-inch drive bays.

v The 2.5-inch models have eight 2.5-inch hot-swap hard disk drive bays and one

3.5-inch tape-drive bay. Install only 2.5-inch hard disk drives and an optional

3.5-inch tape drive in these models.

Throughout this documentation, the terms 2.5-inch models and 3.5-inch models will

be used to distinguish between the server styles.

Performance, ease of use, reliability, and expansion capabilities were key

considerations in the design of the server. These design features make it possible

for you to customize the system hardware to meet your needs today and provide

flexible expansion capabilities for the future.

The server comes with a limited warranty. For information about the terms of the

warranty and getting service and assistance, see the Warranty and Support
