DirectConnect Architecture and
12MB
of integrated Level 3 cache per processor offer solid
performance capable of tackling the toughest jobs.
•
Each processor includes
4 integrated memory controllers
(one per memory channel), for up
to
16 memory controllers per server
.
•
Energy-efficient processors
use less power and produce lest waste heat than less efficient
processors, thus helping to reduce data center energy costs. For example, the 12-core 115W
(maximum) processors
average
only 80W in typical use, which is under 7W per core.
•
All x3755 M3 servers support 2 DIMMs per channel (
2DPC
) at 1333MHz (using 1.5V DIMMs).
•
Fast
PC3-10600 DDR3
ECC memory with
Chipkill
error correction and
online memory
sparing
protection provides speed and high availability.
•
Four
high-speed
PCIe Gen 2
adapter slots offer investment protection by supporting high-
performance adapters, such as 10Gb Ethernet and InfiniBand cards.
•
Integrated
ServeRAID
controllers support
RAID-0/1/10
or
RAID-0/1/10/5/50
standard (model-
specific), upgradeable to
RAID-0/1/10/5/50
.
•
Up to
eight
3.5-inch
hot-swap
SAS
or
SATA
hard disk drives offer high-performance with
high availability.
•
Two
integrated
dual-port Gigabit Ethernet
controllers with
IPMI 2.0
support provide 4 ports
for high-speed network communications.
•
Support for TCP Offload Engine (
TOE
) and RDMA offers higher performance for TCP/IP
traffic, with less overhead on the system processor.
•
A
high degree of device integration
—including quad Gigabit Ethernet, systems
management and video controllers—lowers costs and frees up valuable adapter slots.
Flexibility
The x3755 M3 has the ability to grow with your application requirements, thanks to:
•
A choice of Opteron processors with
1.8
through
2.3GHz
clock rates and
79
-
137W
maximum
power draw.
•
Up to
256GB
of high-speed DDR3 system memory (
64GB
per processor
).
•
Three
available
high-performance
adapter slots (
one PCIe x16, one x8, one x4
in all
models.
•
Hardware-based
support for
RAID-0/1/10
(upgradeable to
RAID-5/50
) is provided standard in
most models. Other models provide
RAID-0/1/10/5/50
standard (upgradeable with
RAID-6/60
and battery backup).
•
The
five USB 2.0
ports are up to
40X
faster
3
than older
USB 1.1
ports. This provides speedy
access to external HDDs (non-arrayed), optical drives, tape drives, and other USB devices.
Two ports are on the front of the unit, one is internal, and two are on the back.
•
Up to
eight
internal 3.5-inch
hot-swap SAS/SATA
HDDs are supported internally (up to
16TB
SATA
or
4.8TB SAS
).
Manageability
Powerful systems management features simplify local and remote management of the x3755 M3:
•
The x3755 M3 includes an integrated
Baseboard Management Controller (iBMC)
to monitor
server availability, perform Predictive Failure Analysis, etc., and trigger IBM Systems Director
alerts. The BMC enables service personnel to use sophisticated diagnostic tools, such as light
path diagnostics and
Serial over LAN
, to resolve problems quickly. The remote presence
feature offers remote control of keyboard, video, and mouse, graphical console redirection
over LAN, remote virtual floppy and CD-ROM, plus the latest OS failure screen capture.
•
Integrated
IPMI 2.0
support alerts IBM Systems Director to anomalous environmental factors,
such as voltage and thermal conditions. It also supports
highly secure remote power
control
using data encryption.
•
Text Console Redirection
support allows the administrator to remotely view x3755 M3 text
messages over Serial or LAN.
•
Integrated industry-standard Unified Extensible Firmware Interface (
UEFI
) next-generation
BIOS. New capabilities include:
– Human readable event logs — no more beep codes
– Complete out-of-band coverage by the Advance Settings Utility to simplify remote setup
– A complete setup solution, allowing adapter configuration functions to be moved into UEFI
