Did you know?

The System x3100 M5 server is a compact, cost-effective, single-processor tower or rack-mountable server that has been optimized to provide outstanding availability, manageability, and performance features to small-to-medium-sized businesses, retail stores, or distributed enterprises. It supports the Intel Xeon E3-1200 v3 “Haswell” family of processors for applications that require performance and stability, and Core i3, Pentium, and Celeron processors for applications that require lower cost.

The system includes features that are not typically seen in this class of system, such as standard, embedded RAID 0 and RAID 1, remote control capabilities even when the machine is powered off, and Predictive Failure Analysis (PFA) on processor and memory. Some models also support hot-swap redundant power supplies and hot-swap disk drives.

Key features

Often, small-to-medium sized businesses (SMBs) have limited IT budget and resources, and rely on partners or multitalented employees to help manage the company’s network. Business needs for efficiency improvement and retention of critical data require the usage of a server that is easy to get up and running quickly and is dependable. You need to squeeze as much as possible out of your IT dollars while saving costs on features that are not needed in an SMB environment. The System x3100 M5 is an ideal first server to meet those business needs. It was built for speed, yet eliminates costly design features that are found in general-purpose servers that are unnecessary for smaller businesses.

Scalability and performance

The x3100 M5 offers numerous features to boost performance, improve scalability, and reduce costs:

• The single-socket x3100 M5 supports the quad-core Intel Xeon Processor E3-1200 v3 ("Haswell") family of processors, which offer impressive computing power in a space-saving mini-tower design.

• Seven USB ports, two USB 3.0 on the front and four USB 2.0 on the back. In addition, there is one internal port for use with a tape drive or RDX Removable Disk Cartridge drive.

Availability and serviceability

The x3100 M5 provides many features to simplify serviceability and increase system uptime:

• ECC memory provides error correction that is not available in PC-class “servers” that use parity memory. Avoiding system crashes (and data loss) because of soft memory errors can mean greater system uptime.
• Tool-less cover removal provides easy access to upgrades and serviceable parts, such as CPU, memory, and adapters.
• Hot-swap drive bays that are available on some models combined with RAID capabilities offer the potential of no downtime in the event of a drive failure.
• The Predictive Failure Analysis (PFA) detects when system components (for example, processors, memory, and hard disk drives) operate outside of standard thresholds and generates pro-active alerts in advance of possible failure, therefore increasing uptime.
• Built-in Integrated Management Module Version II (IMM2) continuously monitors system health, triggers alerts, and performs recovering actions in case of failures to minimize downtime.
• Built-in diagnostic tests using Dynamic Systems Analysis (DSA) Preboot speeds up troubleshooting tasks to reduce service time.
• A DVD-ROM drive is standard in a dedicated bay for easy software installation.
• Redundant hot-swap power supports on some models helps keep the server always running
• One-year customer replaceable unit and onsite limited warranty, next business day 9x5. Optional service upgrades are available.

Manageability and security

Powerful systems management features simplify local and remote management of the x3100 M5:

• The server includes an Integrated Management Module II (IMM2) to monitor server availability and perform remote management (some features require optional license upgrades).
• Integrated industry-standard Unified Extensible Firmware Interface (UEFI) enables improved setup, configuration, and updates, and simplifies error handling.
• Integrated Trusted Platform Module (TPM) 1.2 support enables advanced cryptographic functions, such as digital signatures and remote attestation.
• Intel Xeon Processor E3-1200 v3 family supports Industry-standard Advanced Encryption Standard (AES) NI support for faster, stronger encryption.
• IBM Systems Director is included for proactive systems management. It offers comprehensive systems management tools that help to increase up-time, reduce costs, and improve productivity through advanced server management capabilities.
• The Intel Execute Disable Bit function can help prevent certain classes of malicious buffer overflow attacks when combined with a supporting operating system.

Energy efficiency

The x3100 M5 offers the following energy-efficiency features to save energy, reduce operational costs, increase energy availability, and contribute to a green environment:

• Energy-efficient planar components help lower operational costs.
• Available 350 W power supply, 300 W 80 PLUS Bronze certified power supply, or 430 W hot-swap 80 PLUS Silver certified power supply.
• With the addition of the Operating Temperature Enhancement Kit, the server supports the ASHRAE A3 standard, which means the server can operate in temperatures as high as 40°C. This means potential savings in environmental cooling costs.
• The Intel Xeon processor E3-1200 v3 product family offers significantly better performance over the previous generation while fitting into the same thermal design power (TDP) limits.
• Low-voltage Intel Xeon processors draw less energy to satisfy demands of power and thermally constrained data centers and telecommunication environments.
• The server uses hexagonal ventilation holes, a part of Calibrated Vectored Cooling™ technology. Hexagonal holes can be grouped more densely than round holes, providing more efficient airflow through the system.
