Chapter 3. IBM System x3850 X5 and x3950 X5 109
This page lists the third-party vendors that have performed their own testing of their options
with our servers. This support information means that those vendors agree to support the
combinations that are shown in those particular pages.
Although IBM supports the rest of the System x server, technical issues traced to the vendor
card are, in most circumstances, directed to the vendor for resolution.
3.13 Standard onboard features
In this section, we look at several standard features in the x3850 X5.
3.13.1 Onboard Ethernet
The x3850 X5 has an embedded dual 10/100/1000 Ethernet controller, which is based on the
Broadcom 5709C controller. The BCM5709C is a single-chip high performance multi-speed
dual port Ethernet LAN controller. The controller contains two standard IEEE 802.3 Ethernet
media access controls (MACs) that can operate in either full-duplex or half-duplex mode. Two
direct memory access (DMA) engines maximize the bus throughput and minimize CPU
overhead.
The onboard Ethernet offers these features:
TCP off-load engine (TOE) acceleration
Shared PCIe interface across two internal PCI functions with separate configuration space
Integrated dual 10/100/1000 MAC and PHY devices able to share the bus through
bridge-less arbitration
Comprehensive nonvolatile memory interface
Intelligent Peripheral Management Interface (IPMI)-enabled
3.13.2 Environmental data
x3850 X5 has the following environmental data:
Heat output:
– Minimum configuration: 734 Btu/hr (215 watts per hour)
– Typical configuration: 2,730 Btu/hr (800 watts per hour)
– Design maximum configuration:
• 5,971 Btu/hr (1930 watts per hour) at 110 V ac
• 6,739 Btu/hr (2150 watts per hour) at 220 V ac
Electrical input: 100 - 127 V, 200 - 240 V, 50 - 60 Hz
Approximate input kilovolt-amperes (kVA):
– Minimum: 0.25 kVA
– Typical: 0.85 kVA
– Maximum: 1.95 kVA (110 V ac)
– Maximum: 2.17 kVA (220 V ac)
