The Ideal Entry-level Server

Entry-level server platforms featuring the Intel Xeon processor 3400 series and the Intel 3400 series chipset are ideal for value-conscious organizations looking for their first server or a replacement for an older server. These platforms are designed to deliver 24/7 dependability and improve business productivity with industry-leading performance. These new server platforms are easy to set up and manage, provide trouble-free operation and help ensure that your operational needs are met at every stage of your business growth. Our entry-level server platforms integrate the most advanced technologies:

• Innovative Integration - Intel® Xeon® processor 3400 series is based on the next-generation Intel microarchitecture, with an integrated high speed, 1333 MHz dual-channel DDR3 memory controller and flexible x16 PCI Express* 2.0 controller. The Intel® 3400 series chipset offers additional PCI Express I/O for even more expansion possibilities.
• Memory Flexibility - Intel Xeon processor 3400 series provides flexible memory configurations with support of up to 16 GB of memory with DDR3 Unbuffered DIMMs or 32 GB of memory with DDR3 Registered DIMMs.
• Memory Error Correction – The Intel Xeon processor 3400 series supports Error Correcting Code (ECC) memory to improve reliability and integrity of data by keeping system running by self correcting memory errors.
• Power-Saving Architecture - The Intel Xeon processor 3400 series includes architectural improvements such as Integrated Power Gates that reduce idle CPU cores to near zero power and Automated Low Power States that adjust system power consumption based on real-time CPU loads.
• Intel® Turbo Boost Technology ^2 – The Intel Xeon processor 3400 series is designed with innovative features that adapt performance to software and business needs. With Intel® Turbo Boost Technology, applications take advantage of higher speed execution on demand by using available power to run at a higher frequency.

• Intel® Hyper-Threading Technology ^3 - For applications that lend themselves to parallel, multi-threaded execution, Intel® Hyper-Threading Technology enables simultaneous multi-threading within each processor core, improving multi-threaded application performance.

• Lower Power Option – The Intel® Xeon® processor L3426 operates at only 45W thermal design power (TDP) which provides a 50W TDP reduction from our standard power processors. The lower TDP makes this processor ideal for building entry-level servers for thermally sensitive, space-constrained environments.

• Improved Virtualization Experience – Intel® Virtualization Technology provides hardware assist to virtualization software, enabling your servers to support both 32-bit and 64-bit operating systems and applications on the same server.
• Gigabit Ethernet – Intel® 82574L Gigabit Ethernet Controller and Intel® 82578DM Gigabit Ethernet Connection provide gigabit Ethernet LAN connectivity for high-speed network access.
• External SATA* Support – Native support of external SATA ports (eSATA), combined with Intel® Matrix Storage Technology (Intel® MST), provides the flexibility to add an external drive for increased data storage. Support for eSATA enables the full SATA interface speed of up to 3 Gb/s outside the chassis.
• Data Reliability with RAID – Supports Frame Information Structure (FIS)-based port multipliers, and RAID levels 0, 1, 5, and 10 enable greater reliability for personal data, or maximum storage performance for intensive applications.
• Fast and Easy Recovery – Intel® Rapid Recover Technology (Intel® RRT) provides RAID level 1 configurations, a fast, easy-to-use method to boot instantly off a hard drive clone allowing the end user to recover their data and quickly return their system to an operational status.

Protect Your Critical Data with 24/7 Dependability

Intel Xeon processor 3400 series-based platforms support Error Correction Code (ECC) memory for a high level of data integrity, reliability, and system uptime. ECC can detect multiple-bit memory errors, and locate and correct single-bit errors to keep business applications running smoothly.

With Intel MST, support for RAID levels 1, 5, and 10 data is protected from drive failure through drive redundancy. With RAID 5, digital assets are protected by writing data to multiple hard drives. This makes data recovery easy by simply replacing the failed drive. Intel RRT provides RAID level 1 configurations in a fast, easy-to-use method allowing the end users to recover their data and return their system to an operational status. This is accomplished by supporting the capability to boot instantly off of a hard drive clone.

Improved Productivity

Intel Xeon processor 3400 series-based platforms support technologies that are designed to improve productivity of your server applications. The Intel Xeon processor 3400 series supports up to 6 RDIMMs for flexible memory configurations and future cost-effective upgrades as your business grows. The processors also support up to 32 GB of DDR3 memory to support applications that are memory bound.

Intel MST with Intel® 3420 chipset can improve server performance on disk-intensive retrieval applications by using RAID 0, 5 or 10. In RAID 0 volumes of two drives, and RAID 5 volumes of three to six drives, data can be accessed at higher speeds, because data is striped across multiple drives. Access time is reduced resulting in reduced response time for data-intensive applications. Also, due to drive load balancing, even systems with RAID 1 can take advantage of faster boot times and data reads. In office applications there are more background tasks such as virus scans, data backup, e-mail, and data processing that consume storage resources. Implementing a basic RAID 1 configuration helps alleviate bottlenecks encountered by running these added tasks.

Performance tests and ratings are measured using specific computer systems and/or components and reflect the approximate performance of Intel products as measured by those tests. Any difference in system hardware or software design or configuration may affect actual performance. Buyers should consult other sources of information to evaluate the performance of systems or components they are considering purchasing. For more information on performance tests and on the performance of Intel products, visit www.intel.com/performance/resources/limits.htm or call (U.S.) 1-800-628-8686 or 1-916-356-3104.

All dates and products specified are for planning purposes only and are subject to change without notice.

Relative performance for each benchmark is calculated by taking the actual benchmark result for the first platform tested and assigning it a value of 1.0 as a baseline. Relative performance for the remaining platforms tested was calculated by dividing the actual benchmark result for the baseline platform into each of the specific benchmark results of each of the other platforms and assigning them a relative performance number that correlates with the performance improvements reported.
