Key Features
High-Performance Xeon Processors
The x3650 supports up to two high-performance Intel Xeon processors, allowing you to upgrade
to a second processor as business needs require. The x3650 offers a choice of processor clock
rates, FSB speeds and energy-efficiency:
•
120W quad-core
Xeon processor models
X5450 or X5460
at 3.0, 3.16Ghz respectively
with
64-bit extensions, a
1333MHz
FSB, and
12MB
of L2 processor cache (2 x 6MB)
•
50W quad-core
Xeon processor model
L5420
at 2.5GHz, with 64-bit extensions,
ultralow
power draw
(
12.5W
per core
), a
1333MHz
FSB, and
12MB
of L2 processor cache (2 x 6MB)
•
80W quad-core
Xeon processor models
E5405
,
E5420
,
E5430
or
E5440
at 2.0, 2.5, 2.66, or
2.8GHz (respectively), with 64-bit extensions, a
1333MHz
FSB, and
12MB
of L2 processor
cache (2 x 6MB)
•
50W quad-core
Xeon processor models
L5310
or
L5320
at 1.6 or 1.86GHz (respectively),
with 64-bit extensions,
ultralow power draw
(
12.5W
per core
), a
1066MHz
FSB, and
8MB
of
L2 processor cache (2 x 4MB)
•
65W
dual-core Xeon processor model
E5205
at 1.86GHz, with 64-bit extensions,
low power
draw
, a
1066MHz
FSB, and
6MB
of
shared
L2 processor cache
•
80W
dual-core Xeon processor model
E5160
at 3.0GHz, with 64-bit extensions, a
1333MHz
FSB, and
4MB
of L2 processor cache (2 x 2MB)
•
65W
dual-core Xeon processor models
E5130
or
E5140
at 2.0 or 2.33GHz, with 64-bit
extensions, ,
only
32.5W
per core of power draw
, a
1333MHz
FSB, and
4MB
of L2 processor
cache (2 x 2MB)
•
65W
dual-core Xeon processor model
E5110
at 1.6GHz, with 64-bit extensions,
only
32.5W
per core of power draw
, a
1066MHz
FSB, and
4MB
of L2 processor cache (2 x 2MB)
Dual-core Xeon
processors contain
two complete processor cores
;
quad-core
processors,
similarly, contain
four
cores. Some processors contain one
unified
cache
shared
by all cores,
while other processors have
independent
caches (one per core or pair of cores). The shared
cache is dynamically allocated between the cores as needed. The multiple cores appear to
software as multiple physical processors. The dual-core processors offer considerably higher
performance than a same-speed Xeon processor with a single core. Likewise, quad-core
processors offer considerably higher performance than a same-speed Xeon processor with dual
cores.
Intel
Extended Memory 64 Technology (EM64T)
64-bit extensions allow the Xeon processor
to use large memory addressing when running with a 64-bit operating system. This in turn lets
individual software processes directly access more than 4GB of RAM, which was the limit of 32-
bit addressing. This can result in much higher performance for certain kinds of programs, such
as database management and CAD. Additional registers and instructions (SSE3) can further
boost performance for applications written to use them. Contact your software providers to
determine their software support for EM64T.
The
1066MHz
FSB (which connects memory to the processor) boasts a peak rate of
8.53GBps
,
or up to
one-third
higher throughput at the same processor clock speed than an
800MHz
FSB
(
6.4GBps
) used in older systems. The
1333MHz
FSB offers a peak rate of
10.67GBps
, or up to
two
-
thirds
higher throughput at the same processor clock speed than an
800MHz
FSB. This
may result in much higher data transfer rates.
Intelligent Power Capability
powers individual processor elements on and off as needed, to
reduce power draw.
Execute Disable Bit
functionality can help prevent certain classes of malicious buffer overflow
attacks when combined with a supporting operating system.
DDR II ECC Fully Buffered Memory with Chipkill Protection
The x3650 supports up to
48GB
of memory in
12
DIMM sockets. Some models include
two
512MB
DIMMs standard, while others ship with
two 1GB
DIMMs. The x3650 uses
PC2-5300
fully-buffered
double data rate II (DDR II) memory (operating at
667MHz
) for faster access,
and provides Active Memory features, including advanced
Chipkill
memory protection, for
up to
16X
better error correction than standard ECC memory.
The fully buffered memory in the x3650 provides up to
triple
the memory bandwidth (up to
21.3GBps
in
four
channels of PC2-5300 fully-buffered DIMMs vs. a maximum of 6.4GBps in two
channels of unbuffered PC2-3200 memory) and up to
triple
the system memory capacity (
12
DIMMs x
4GB
) of the predecessor x346 server (8 DIMMs x 2GB). By performing reads and
writes simultaneously, it eliminates the previous memory read-to-write blocking latency. In
addition, it also offers innovative data reliability and security features to help improve data
integrity, including enhanced CRC protection, data retry on error detect and buffer registers for
