the Virtual Media Key and the ServeRAID-BR10i controller can be installed and replaced
without tools. This means less time (and therefore less money) spent servicing the x3550 M2.
Similarly, hot-swap/redundant HDDs, fans and power supplies, as well as online mirrored
memory, mean greater system uptime while these components are being serviced.
• New toolless slides ship with the server, together with a Cable Management Arm (CMA),
that allows the rack server to easily slide into place
• IBM Thermal Diagnostics allows the administrator to evaluate thermal data on the server
without taking the hardware offline. This can provide greater server uptime.
• The drop-down light path diagnostics panel and individual light path LEDs quickly lead the
technician to failed (or failing) components. This simplifies servicing, speeds up problem
resolution and helps improve network availability.
• Integrated RAID-1 disk mirroring and RAID-10 striped mirrored arrays standard enable
the server to keep operating in the event of a failure to any one drive.
• IPMI 2.0 supports highly secure remote system power control using data encryption. This
allows an administrator to restart a server without having to visit it in person, saving travel time
and getting the server back up and running quickly and securely. It also adds new features to
those provided by IPMI 1.5, including VLAN support, Serial over LAN, enhanced
authentication and encryption algorithms (RMCP+, SHA-1, AES) and a firmware firewall.
• Altitude- and temperature-controlled fans adjust to compensate for changing thermal
characteristics. At the lower speeds they draw less power and suffer less wear. Equally
important in a crowded data center, temperature-controlled fans produce less ambient noise in
the data center than if they were constantly running at full speed.
• The three-year (parts and labor) limited onsite warranty

helps afford you peace of mind
and greater investment protection than a one-year warranty does.
Key Features
High-Performance Xeon 5500 Series Processors
The x3550 M2 supports up to two high-performance Intel Xeon processors, allowing you to
upgrade to a second processor as your business needs require. The x3550 M2 offers a choice of
processor clock rates, memory access speeds and energy efficiency, including:
• 95W quad-core Xeon 5500 Series Processor advanced performance models X5570, X5560,
or X5550 at 2.93, 2.8, 2.66GHz respectively running 6.4GT (gigatransfers/second) with 8MB
of L3 processor cache, 1333MHz memory access, and Intel Turbo Boost technology.
• 80W quad-core Xeon 5500 Series Processor standard performance models E5540, E5530,
or E5520 at 2.53, 2.4, 2.26GHz respectively running 5.8GT with 8MB of L3 processor cache,
1066MHz memory access, and Intel Turbo Boost technology.
• 80W quad-core Xeon 5500 Series Processor basic models E5506 and E5504 at 2.13 and
2.0GHz running 4.8GT with 4MB of L3 processor cache and 800MHz memory access.
• 60W quad-core Xeon 5500 Series Processor low-voltage models 5520, L5506 at 2.26,
2.13GHz respectively running 5.8GTand 4.8GT with 8MB and 4MB of L3 processor cache,
1066MHz memory access, and Turbo Boost technology.
• 80W dual-core Xeon 5500 Series Processor model E5502 at 1.86GHz running 4.8GT with
4MB of L3 processor cache and 800MHz memory access.
With the Xeon 5500 Series processors, Intel has diverged from its traditional Symmetric
Multiprocessing (SMP) architecture to a Non-Uniform Memory Access (NUMA) architecture. The
Xeon 5500 processors are connected through a serial coherency link called QuickPath
Interconnect (QPI). QPI is capable of 6.4, 5.6 or 4.8 GT/s (gigatransfers per second), depending
on the processor model.
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 multiple independent caches (one per 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.
Turbo Boost Technology dynamically turns off unused processor cores and increases the clock
speed of the cores in use, by up to two model frequencies. For example, with three cores active,
