Microprocessor:
v Intel Xeon EX versions of the 6000
and 7000 Series or E7 Series
multi-core microprocessor with up
to 24 MB or 30 MB last level cache.
v 1066 MHz front-side bus (FSB)
v Support for up to four
microprocessors
– Four Quick Path Interconnect
(QPI) links per microprocessor at
up to 6.4 GT/s (gigatransfers per
second)
– Four Scalable Memory
Interconnect (SMI) links per
microprocessor at up to 6.4 GT/s
Note: Use the Setup utility to
determine the type and speed of the
microprocessors. The server does not
support mixing microprocessor types.

GB, and 32 GB (Types 7143 and
7191 only) (PC3L-8500-777 DDR3
ECC running at 1066 Mb/sec) in
pairs
v Minimum (Types 7145 and 7146): 2
GB (two DIMMs per memory card
minimum)
v Minimum (Types 7143 and 7191): 4
GB (two DIMMs per memory card
minimum)
v Maximum: 1 TB (2 TB when using
32 GB DIMMs in Types 7143 and
7191) (eight memory cards, each
card containing 8 DIMM connectors
for a total of 64 DIMMs)
v Connectors: Two-way interleaved,
eight dual inline memory module
(DIMM) connectors per memory
card
v Supports 1.35-volt (low-voltage)
and 1.5-volt registered DIMMs
v Machine Types 7145 and 7146 uses
the Intel 7500 Scalable Memory
Buffer only
v Machine Types 7143 and 7191 uses
the Intel 7510 Scalable Memory
Buffer only
Expansion slots:
v Six non-hot-swap PCI Express x8
(three full-length and three
half-length) slots (slot 2 is
electrically x4)

x16 (full-length) slot
v Emulex 10 GbE Custom Adapter
for IBM System x in slot 7
(optional in some models)
Upgradeable microcode:
System UEFI, FPGA, diagnostics,
service processor, IMM, and SAS
microcode
Power supply:
v Standard: One or two dual-rated
power supplies (depending on the
model).
– 1975 watts at 220 V ac input
– 875 watts at 110 V ac input
v Hot-swappable and redundant at
220 V ac, only with two power
supplies
v If the server is operating at 110 V
ac, a second power supply must
be installed.

altitude: 0 to 914 m (3000 ft).
- 10°C to 32°C (50°F to 90°F);
altitude: 914 to 2133 m (7000
ft).
– Server off: 10°C to 43°C (50.0°F to
109.4°F); maximum altitude: 2133
m (6998.0 ft)
v Humidity:
– Server on: 8% to 80%
– Server off: 8% to 80%
v Particulate contamination:
Attention: Airborne particulates
and reactive gases acting alone or in
combination with other
environmental factors such as
humidity or temperature might pose
a risk to the server. For information
about the limits for particulates and
gases, see “Particulate
contamination” on page 123.
Heat output:
Approximate heat output:
v Minimum configuration: 648 Btu per
hour (190 watts)

hour (1100 watts)
v Design maximum configuration:
– 5971 Btu per hour (1930 watts) at
110Vac
– 6739 Btu per hour (2150 watts) at
220Vac
