Leadership enterprise server with significantly lower cost of ownership in a highly available and

expandable, rack-dense, 1U dual-socket server

Please see the Legal Information section for important notices and information.

– Offers up to 8X more IOPS than HDDs (67/33% read/write OLTP transaction base mix)

– Optimized for heavy mix of read and write operations, such as transaction processing,

media streaming, surveillance, file copy, logging, backup/recovery, and business

Intelligence

 Lower-Cost IOPS Performance

– Yields better $/IOPS: lower capacity (GB) required to achieve higher IOPS

– Uses less energy and generates less heat than a hard disk drive

 Superior Uptime

– 3X the availability of mechanical disk drives

– No moving parts to fail

– Enterprise wear-leveling to extend life even further

 Full OS Support

– Supports all ServerProven OSes

The hot-swap SAS drives use the Converged Tray for interchangeability with other IBM System x

systems. If you need more storage space, terabyte capacities are possible with external IBM

System Storage direct-attach, NAS and SAN offerings.

High-Performance Adapter Slots

The x3550 M3 provides two x16 (“by 16”) 16GBps PCIe Gen 2 (PCI Express) Gen 2 I/O slots for

long-term investment protection. PCI Express Gen 2 is the next-generation of high-performance,

low-latency, serial I/O bus. Each slot is capable of supporting x1/x4/x8/x16 Gen 1 or Gen 2

adapters at full speed. One slot is full-height, half-length. The other is low profile. Each is

convertible to one PCI-X/133 MHz using an optional riser. High-performance x16 Gen 2 slots are

ideal for digital media, 2D graphics environments, and other I/O-intensive applications.

There is also a dedicated riser card in the x3550 M3 that provides a x8 PCIe connector wired with

x4 lanes for an internal ServeRAID card.

Dual-Port Gigabit Ethernet Controller

The x3550 M3 includes one dual-port integrated Broadcom 5709S Gigabit Ethernet controller

standard, for up to 10X higher maximum throughput than a 10/100 Ethernet controller, as well as

support for TOE (TCP Offload Engine), as well as load-balancing and failover capabilities

between the two ports.

TOE helps improve overall system performance by offloading TCP/IP protocol processing from the

system microprocessor to the onboard Ethernet TOE processor.

It also supports highly secure remote power management using IPMI 2.0, plus Wake on LAN

and PXE (Preboot Execution Environment) flash interface. Optional PCI adapters offering failover

and load balancing between adapters are available for added throughput and increased system

availability.

Integrated quad Gb Ethernet ports:

• Up to four Gb Ethernet ports, ideal for virtualization and I/O-intensive workloads

• 2 ports standard, plus two additional ports via optional daughtercard

• Improves system performance by offloading protocol processing from CPU to a separate TOE

engine

• Primary performance improvement for data copying (CPU) where CPU utilization is 90-100%

The 5709S controller supports IEEE 802.3 for 1000Base-T, 100Base-TX, and 10Base-T

applications (802.3, 802.3u, 802.3ab) through a RJ-45 connector to an Ethernet network over a

CAT 5 twisted-pair cable. TOE support on Windows is available today, but requires the Windows

Scalable Network Pack (SNP) installed. Linux has no plan to support TOE at this time.

10 Gigabit Ethernet Integrated Virtual Fabric Adapter for IBM

The Emulex Virtual Fabric Adapter for x3550 M3 (part number 49Y4200 with special riser card,

support by CTO) is an industry-leading performance and scalability per watt, dual-port network

adapter for 10Gbps Ethernet (10GbE) networks. It offers the benefits and flexibility of I/O

convergence in a single end-to-end solution. Protocol offload for stateless TCP/IP and TCP

Chimney provide maximum bandwidth with minimum use of CPU resources. It achieves line rate

10Gbps performance with support for TCP/IP stateless offloads and TCP Offload Engine (TOE)

support. TOE reduces system processor utilization, providing increased system performance and

1TB SAS and 250GB/1TB SATA drives available in 2Q/2011.
