System Overview
Dell™ PowerVault™ 770N Systems Service Manual
Your Dell™ PowerVault™ 770N NAS system provides optimized file-serving capabilities on a robust rackmount or tower
platform. The base configuration features one Intel® Xeon™ microprocessor with 512 MB of memory. The maximum
configuration includes two Xeon microprocessors with up to six memory modules.
This section describes the major features of the system, including those that simplify servicing. It also provides information
about other documents you may need when setting up your system, and technical specifications for the system.
System Features
One or two Intel Xeon microprocessors with an internal operating speed of at least 1.8 GHz, a 512 KB cache, and a
front-side (external) bus speed of 400 MHz.
SMP is available on systems with two Xeon microprocessors. SMP greatly improves overall system performance by
dividing microprocessor operations between independent microprocessors. To take advantage of this feature, you must
use an operating system that supports multiprocessing.
NOTE:
If you decide to upgrade your system by adding an additional microprocessor, you must order the
microprocessor from the company where you purchased your system. Not all versions of the Intel Xeon microprocessor
will work properly as an additional microprocessor. The upgrade kit contains the correct version of the microprocessor
as well as the instructions for performing the upgrade. All microprocessors must have the same internal operating
frequency and cache size.
A minimum of 256 MB of system memory. To add additional system memory, install identical pairs of DDR SDRAM
DIMMs in the six DIMM sockets on the system board.
Support for up to six 1-inch, internal Ultra320 or Ultra160 SCSI hard drives.
Support for two additional 1-inch internal hard drives in the external peripheral bay.
Support for one full-height or one half-height tape drive.
Support for RAID levels 0, 1, 5, and 10.
A 1.44-MB, 3.5-inch diskette drive.
An IDE CD drive.
Up to two hot-pluggable, 730-W power supplies with optional 1 + 1 redundant configuration.
Five hot-pluggable system cooling fans.
An intrusion switch that signals the appropriate systems management software if the bezel is removed.
