operating systems on the same integrated hardware
•
Support for
up to two ServeRAID-MR10k options

Key Features
High-Performance Xeon Processors
The x3850 M2 and x3950 M2 ship with
two
high-performance Intel
Xeon
processors, and
support up to
four
, allowing you to upgrade as business needs require. The eX4 servers also go
a step further by allowing you to add additional nodes (chassis) to increase the number of
sockets from
4
to as many as
16
(using
four
total chassis). (The
ScaleXpander Option Kit
converts a 4-socket x3850 M2 into an ultra-expandable x3950 M2.) With multiple chassis, you
can use physical partitioning to segment the one physical server into multiple logical servers for
virtualization.
Processors can be added or replaced through the top cover of the system. The system offers a
choice of processor clock rates, FSB speeds and power draw:

The
dual-core Xeon
processors contain
two complete processor cores
. Each processor
contains
two 4MB
L2 caches,
4MB
per
core
(
8MB
total
per processor). The two cores appear
to software as separate physical processors. The dual-core processors can offer more than
double the performance of a same-speed single-core Xeon processor (depending on workload).
Similarly,
quad-core
Xeon processors contain
four
processor cores. The cores share dual
2MB
,
3MB
, or
4MB
L2 caches (
4MB
,
6MB
, or
8MB
total per processor). That is,
two
cores per
L2 cache. They can offer more than double the performance of dual-core Xeon processors
(again, depending on workload). The
six-core
processors contain
six
processor cores. The
cores share dual
4MB
,
6MB
, or
8MB
L2 caches (
8MB
,
12MB
, or
16MB
total per processor).
The servers provide
four
separate
1066MHz
FSBs
(front-side buses),
one per processor
.
Each
of the four FSBs (which connect memory and I/O to the processor) boasts a peak rate of
8.53GBps
(
34.1GBps
aggregate).This contrasts to the
two 667MHz FSBs
(with up to two
processors per FSB) provided in the original x3850/x3950 models. In other words, you now have
