1: Introduction and Overview
Serial ATA
Each node board chipset includes a Serial ATA controller. Some workstation boards use the
ICH10R chipset for up to six Gb/s SATA drive transfers. The SATA drives are connected to
power, bus termination and configuration settings on each tray. Optional SATA RAID may be
supported depending on the configuration you ordered. Contact your sales or service provider to
order a specific RAID upgrade if your system was not ordered with that option.
PCI Expansion Slots
PCI expansion is available as part of specific workstation tray configurations. Each tray within the
cluster system supports the use of PCI Express 2.0 x16, and 2.0 x8 slots. Riser cards are
pre-installed to support the optional low-profile add-on PCIe cards. The type of graphics card(s)
used with the workstation will determine which slots are used and the availability/usability of
additional slots.
Note that PCIe cards (other than graphics cards) must be for internal applications as there are
limited external ports on the enclosure.
Optional Ethernet Ports
An optional network controller can be integrated into some models of the internal
compute/graphics tray to support additional Gigabit LAN ports with 1000BaseTX, RJ45 output.
Optional Graphics Controllers
Different optional graphics cards may be available for specific tray configurations, check with
your sales or service representative for additional information.
Other Features
Other node-board features that promote system health include voltage monitors, auto-switching
voltage regulators, chassis and CPU overheat sensors, virus protection and BIOS rescue.
