Leadership enterprise server with significantly lower cost of ownership in a highly available and expandable, rack-dense, 1U dual-socket server
the Virtual Media Key and the ServeRAID-BR10icontroller 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 warranty4 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-coreXeon 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-coreXeon 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-coreXeon 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-coreXeon 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-coreXeon 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,
