IBM System X M4 Server Overview

Dual-socket servers that use Intel® Xeon® processors have become the most widely used servers due to their outstanding performance, large memory capacity, and excellent performance per watt. They are commonly found throughout the data centre running applications such as virtualisation, web infrastructure, databases, general office applications, and high-performance computing (HPC). In March 2012, Intel performed a major redesign update on these processors, launching the Intel Xeon E5-2600 product family and C600 chipset. These processors feature a number of new and innovative improvements that help to deliver improved performance, bandwidth, and energy efficiency.

    IBM System x leverages these Intel platform improvements in its new System x M4 servers, the x3550 M4, x3650 M4, and x3500 M4. These servers not only have outstanding performance and energy efficiency, but they also feature advanced manageability and resiliency features. A wide range of storage options are available as well, including both 2.5-inch and 3.5-inch hard disk drives, and 1.8-inch solid-state drives (SSDs). IBM’s Feature on Demand allows customers to customise and upgrade the servers as business needs change and evolve.

    The performance and energy efficiency of these new M4 servers make this generation a compelling choice for those who have older servers in their  data centres. Performance has improved over 10x compared to servers purchased just six years ago, and energy efficiency has improved 5x over the last four generations.

    1 As a result, Ideas International (IDEAS) recommends that all data centre managers reassess their installed servers and replace all servers using Intel Xeon 5500 or older processors with new M4 servers. This server upgrade will not only bring the data centre up to date, but it will also save money through better energy efficiency and reduced management complexity due to server sprawl.

How IBM Is Leveraging This New Technology with the M4 Servers

IBM is rolling out the new Intel E5-2600 product family platform across all its dual-processor Xeon server product lines, including the x3500, x3550, and x3650. These are some of IBM’s best-selling servers because they deliver outstanding performance and energy efficiency for mission-critical applications at an excellent price point. Many of IBM’s customers rely on these dual-socket servers to run their core business operations. IBM’s new M4 servers include the following:

    The  x3650 M4 is the flagship of IBM’s rack server lineup. With support for up to 16 highperformance, hot-swappable 2.5-inch hard disk drives (or 6 x 3.5-inch drives, or 32 x 1.8- inch SSDs) and four to six PCI Express Gen 3.0 I/O slots in an energy efficient 2U chassis, the x3650 M4 is well positioned to handle cloud computing, virtualisation, databases, Web 2.0, file/print, web serving, enterprise business infrastructure, virtual PC consolidation, and low-end UNIX migration. 

    The  x3550 M4  is similar to the x3650 M4 in that it supports the same processors and memory, but in a 1U rack format. With its smaller size, it only supports eight 2.5-inch drives or three 3.5-inch drives and two PCI Express or PCI-X slots. The x3550 M4 serves the same markets as the x3650 M4.

    The x3500 M4 is IBM’s dual-socket tower server that can be converted to a 5U rackmount server. With the same processors and memory as its rack-server cousins, the x3500 M4 delivers similar performance and thermal efficiency. Where it differs is in its much greater expandability and physical size. The x3500 M4 supports up to 32 x 2.5-inch disk drives (8 x 2.5-inch or 3.5-inch drives are standard), up to seven PCI Express G3.0 slots, and one G2.0 slot (PCI-X slots are optional). The x3500 M4 is ideal for small businesses and branch offices. With up to 32 TB of SAS or SATA capacity, it can also be used as a storage server. For many small and midsize businesses, this server may be the only one they will need to purchase. 

    IBM’s M4 servers are an evolutionary improvement to the prior-generation M3 servers. The M3 servers were very balanced, well-designed servers with great energy efficiency. This new generation adds a number of enhancements over prior generations, including:

    Performance – The new Intel Xeon processor E5-2600 product family helps to deliver up to a 10x performance improvement over servers purchased just six years ago.

    6 A 270% increase in memory capacity over the last generation

    7 ensures that the M4 servers will never run low on memory, even when virtualised, as the x3650 M4, x3550 M4 and x3500 M4 will support an amazing 768 GB. All of that performance needs a way to communicate, and the new PCI Express I/O subsystem helps to deliver. With four or six PCI Express (including double-width PCI Express) or PCI-X slots, the x3650 M4 delivers strong I/O flexibility as well as performance. For those who need them, 10GbE mezzanine cards are available and InfiniBand cards will be available soon.

    Energy efficiency –  The Intel Xeon E5-2600 product family platform delivers outstanding energy efficiency over previous generations. The efficiency of servers employing this new Intel platform is especially compelling when compared to servers with processors that are
