Your challenge is to do more with less—serve more Web pages, handle more secure connections, support more e-mail users. You need to reduce the costs of doing business and improve the service you deliver to your customers while lower your overall risk. The dual-socket IBM® System x3550 M2 can reduce your costs with its new energy smart design. It can improve y service with reduced operational complexity and increased management functionality. It will lower your IT risk with the resiliency that comes from no single point of failure. And like all IBM servers, the x3550 M2 offers you the trust that comes from the IBM global reach, service and support. The x3550 M2 is not simply an upgrade on a previous server. It is one of our new generation of X-Architecture servers. It is a game-changing, completely redesigned rack server using significantly less power with unified systems management tools, leadership reliability, availability, serviceability features and broad systems flexibility housed in a compact 1U mechanical package. The x3550 M2 features the Intel® Xeon® 5500 Series Processors, designed with 64-bit extensions (EM64T), and either 8MB or 4MB of L3 cache, to help provide you with the computing power you need to match your business needs and growth. This new line of Intel processors delivers unprecedented intelligent performance with features like adaptive performance for applications and environments, turbo boost and hyper-threading technology, and integrated power gates and automated power management. The x3550M2 uses up to 16 DIMMs with 128GB of registered 1333MHz DDR3 memory with Chipkill™ ECC (Error Checking and Correcting) protection—for high performance and reliability. For even higher levels of availability, the x3550M2 also offers online memory mirroring. Up to 4 integrated high-speed Gigabit Ethernet controllers with TOE (TCP Offload Engine) and Jumbo Frame support are available, as are two high-performance adapter slots (PCIe x16). The x3550M2 offers an optional embedded hypervisor to manage your virtual workloads. The x3550 M2 offers a choice of up to six high-performance hot-swap hard disk drives with an internal storage capacity of 1.8TB (six 2.5-inch hot-swap Serial-Attached SCSI (SAS) or SATA HDDs) Optional solid-state drives are also available to keep power low and improve resiliency and offer up to 300GB of storage. The server supports a choice of four IBM ServeRAID® storage controllers which provide broad levels of hardware-based RAID solution
The x3550 M2 offers numerous features to boost performance and reduce costs: • Up to two quad-core or dual-core Xeon 5500 Series processors and 8MB or 4MB of integrated Level 3 cache per processor, offer superior performance capable of tackling the toughest jobs. 64-bit extensions provide the flexibility to run 32-bit and 64-bit applications concurrently. Xeon 5500 series processors offer up to 225% better performance than the previous-generation 5400 series processors and up to 900% better performance than the single-core processors of a few years ago that you may still be using. • Low-voltage processors draw less energy and produce less waste heat than high-voltage processors, thus helping to reduce data center energy costs. Some quad-core Xeon 5500 Series processors use only 60W. This is less than half the wattage consumed by older 130W processors. • Sixteen DIMMs of ultra-fast registered 1333MHz DDR3 ECC memory with Chipkill1 protection provides speed, high availability, and a memory capacity of up 128GB. • Optional 32GB and 50GB solid-state drives (SSD) use only 2W of power per drive, vs. 910W for 2.5-inch HDDs. This is as much as 80% less power than a 2.5-inch HDD would use (with a corresponding reduction in heat output). • The x3550 M2 is a leader in server resiliency. With hot-swap power supplies, fans, and storage, the x3550 M2 has no single point of failure. • The altimeter works in conjunction with IMM to govern fan rotation based on the readings which it delivers to save money under normal conditions because the fans do not have to spin at high speed. • Two high-speed PCIe x16 adapters (Gen 2) slots offer investment protection by supporting high-performance adapters, such as 10Gb Ethernet, Fibre Channel and InfiniBand™ cards, none of which will run in older 33MHz and 66MHz conventional PCI slots. • Integrated ServeRAID-BR10i provides RAID-0/1/10 support without consuming a valuable adapter slot. RAID-0/1/10 offers improved disk performance via data striping; RAID-1 offers disk mirroring for high availability, and RAID-10 combines the benefits of speed and availability. The x3550 M2 also supports full RAID-0/1/10/1E/5/6 support using the optional ServeRAID-MR10i card. It also offers higher performance, due to the 256MB battery-backed onboard cache. • Up to six 2.5-inch hot-swap SAS hard disk drives offer high-performance with high availability. The SAS controller provides full-duplex (2 x 300MBps) data transfers for SAS drives. • The integrated dual Gigabit Ethernet controllers with IPMI 2.0 support provide high-speed network communications. Jumbo Frames offer higher efficiency transfers for large data packets. Two more NICS can be supported on the planar with an additional Dual Port GbE daughter card. • The TCP Offload Engine (TOE) feature offers higher performance for TCP/IP traffic, with less overhead on the system processor. • A high degree of device integration—including SAS/SATA or SSD, multiple ServeRAID options, up to four Gigabit Ethernet ports, systems management and video controllers— lowers costs and frees up valuable adapter slots.
High-Performance Adapter Slots The x3550 M2 provides two x16 (“by 16”) 5GBps PCIe (PCI Express) Gen 2 high performance I/O slots help double performance vs. x3550 for added long-term investment protection (2 PCI x16 std). Each is capable of supporting x1/x4/x8 adapters at full speed. One slot is full height, half length The other is low profile.. Two (2) PCI-E Gen 2 slots 1 x16- Full height, half length, Convertible to one PCI-X/133 MHz with riser option 1 x16 – Low Profile Convertible to one PCI-X133 MHz with riser option All new adapter development is on PCI Express Example no 8GB fibre for PCI-X Good for digital media, 2D graphics environments PCI Express is a high-performance, low-latency, next-generation serial I/O bus that is rapidly replacing the older parallel PCI and PCI-X buses. A x16 PCIe adapter offers approximately eight ttimes the maximum throughput of a 133MHz PCI-X adapter7. (A x1 adapter offers throughput similar to a 66MHz PCI-X slot.
The x3550 M2 supports up to 128GB of memory in sixteen DIMM slots. Redesign in the architecture of the Xeon 5500 Series processors bring radical changes in the way memory works in these servers. For example, the Xeon 5500 Series Processor integrates the memory controller inside the processor, resulting in two memory controllers in a 2-socket system. Each memory controller has three memory channels. Depending on the type of memory, population of memory, and processor model, the memory may be clocked at 1333MHz, 1066MHz or 800MHz.
Note: If only one processor is installed, only the first eight DIMM slots can be used. Adding a second processor not only doubles the amount of memory available for use, but also doubles the number of memory controllers, thus doubling the system memory bandwidth. If you add a second processor, but no additional memory for the second processor, the second processor has to access the memory from the first processor “remotely,” resulting in longer latencies and lower performance. The latency to access remote memory is almost 75% higher than local memory access. So, the goal should be to always populate both processors with memory. The X55xx models support up to 1333MHz memory, while the E55xx-and-up and L55xx-and-up models support up to 1066MHz memory, and the E550x models support 800MHz memory only. Using 1333MHz memory (where supported) versus 1066MHz offers up to 9% better performance, while 1066MHz memory produces up to 28% better performance than 800MHz memory. Xeon 5550 series processors access memory with almost 50% lower latency than the previous generation 5400 series processors. That can result in faster processing of latency-sensitive workloads. This new processor design comes with some trade-offs in memory capacity, performance, and cost
application performance and scalability. Memory interleaving refers to how physical memory is interleaved across the physical DIMMs. A balanced system provides the best interleaving. A Xeon 5500 processor-based system is balanced when all memory channels on a socket have the same amount of memory. A memory rank is simply a segment of memory that is addressed by a specific address bit. DIMMs typically have 1, 2 or 4 memory ranks, as indicated by their size designation. A typical memory DIMM description is 2GB 4Rx8 DIMM The 4R designator is the rank count for this particular DIMM (R for rank = 4) The x8 designator is the data width of the rank It is important to ensure that DIMMs with appropriate number of ranks are populated in each channel for optimal performance. Whenever possible, it is recommended to use dual-rank DIMMs in the system. Dual-rank DIMMs offer better interleaving and hence better performance than single-rank DIMMs. For instance, a system populated with six 2GB dual-rank DIMMs outperforms a system populated with six 2GB single-rank DIMMs by 7% for SPECjbb2005. Dualrank DIMMs are also better than quad-rank DIMMs because quad-rank DIMMs will cause the memory speed to be down-clocked. Another important guideline is to populate equivalent ranks per channel. For instance, mixing one single-rank DIMM and one dual-rank DIMM in a channel should be avoided. Note: It is important to ensure that all three memory channels in each processor are populated. The relative memory bandwidth decreases as the number of channels populated decreases. This is because the bandwidth of all the memory channels is utilized to support the capability of the processor. So, as the channels are decreased, the burden to support the requisite bandwidth is increased on the remaining channels, causing them to become a bottleneck. For increased availability, the x3550 M2 offers an additional (but mutually exclusive) level of IBM Active Memory protection: online memory mirroring.. Memory mirroring works much like disk mirroring. The total memory is divided into two channels. Data is written concurrently to both channels. If a DIMM fails in one of the DIMMs in the primary channel, it is instantly disabled and the mirrored (backup) memory in the other channel becomes active (primary) until the failing DIMM is replaced. One-half of total memory is available for use with mirroring enabled. (Note: Due to the double writes to memory, performance is affected.) Mirroring is handled at the hardware level; no operating system support is required. DDR-3 memory is available in 1GB, 2GB, 4GB and 8GB DIMMs. DIMMs are installed individually (not in pairs).
The x3550 M2 contains six drive bays in all. Hot-swap drives may be inserted or removed through the front of the server without powering off the system. Simple-swap solid state drives can be inserted or removed through the front of the server as well; however, the system power must first be turned off. For additional storage, a direct-attach, NAS or SAN external expansion option can be added, using an optional controller. A 24X/24X/24X/8X5 speed (ultraslim, 0.5”) CD-RW/DVD-ROM Combo drive with an IDE interface ships standard in all x3550 M2 servers. No diskette drive is supplied with any model; an external USB floppy drive may be used, if needed.
Disk Controllers All SAS-equipped x3550 M2 models include an integrated ServeRAID-BR10i SAS/SATA controller. This controller supports up to six internal SAS, SATA or solid state drives. The integrated ServeRAID-BR10i controller offers hardware RAID-0/1/1E support. The controller provides data transfer speeds of up to 3Gbps6 per SAS port on an 8-lane 2.5 Gbps PCIe card. It connects to both SAS, SATA and SSD HDDs and tape drives. The x3550 M2 also supports full RAID-0/1/10/1E/5/6 support using the optional ServeRAIDMR10i card. It also offers higher performance, due to the 256MB battery-backed onboard cache. The x3550 M2 also supports hardware based full disk encryption with RAID-0/1/10/1E/5/6
support using the optional ServeRAID-MR10is card. For external storage, the ServeRAID MR10M controller enables connection to up to four IBM System Storage EXP3000 SAS expansion units (48 HDDs total). It provides RAID-0/1/10/5/50 support and 256MB of onboard cache Additional external storage is available.
HDD Storage Capacity The x3550 M2 offers a flexibility with up to six (6) 2.5” HDD bays; optimal price/performance disk drives that provide ultimate drive density and allow you to scale up as your business grows Support for 6 x 300GB SAS hot swap HDD ~ 1.8TB total internal SAS storage Support for 6 x 300GB SATA hot swap HDD ~ 1.8TB total internal SATA storage (500GB SATA HDD planned 3Q09) Support for solid state drives (SSD); 32GB or 50GB capacity deployable in all 6 HDD bays • 32GB SSD – Slim FF (2.5”) HS HDD (SATA interface) or Simple Swap HDD • 50GB SSD – Slim FF (2.5”) High IOPS Hot Swap HDD (SATA Interface) or Simple Swap HDD • High IO Performance – Up to 8X IOPS more than HDD (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, Business Intelligence Lower Cost IOPS Performance – Yield better $/IOPS: Less capacity (GB) required to achieve higher IOPS – Utilizes Less power and heat than conventional disk drive Superior Uptime – 3X the availability of mechanical drives with RAID-1 – No moving parts to fail – Enterprise wear leveling to extend life even further Flexible Deployment With Full OS Support – Traditional HDD Form Factor Offerings – Supports Linux, Windows and VMware 2-5-inch drives not only require less space than 3.5-inch drives, they weigh less, consume half the power, produce less noise, seek faster, and offer increased reliability. 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 directattach, NAS and SAN solutions.
Powerful systems management features simplify local and remote management of the x3550 M2: • The x3550 M2 includes the IMM to monitor server availability, perform Predictive Failure Analysis, etc., and trigger IBM Systems Director alerts. The IMM enables service personnel to use sophisticated diagnostic tools, such as light path diagnostics, to resolve problems quickly. • Integrated industry-standard Unified Extensible Firmware Interface (UEFI) next-generation BIOS. New capabilities include: Human readable event logs – no more beep codes Complete setup solution by allowing adapter configuration function to be moved into UEFI Complete out-of-band coverage by Advance Settings Utility to simplify remote setup • Integrated Trusted Platform Module (TPM) 1.2 support. • Integrated IPMI 2.0 support alerts IBM Systems Director to anomalous environmental factors, such as voltage and thermal conditions. It also supports highly secure remote power control using data encryption. • IBM Systems Director Active Energy Manager™, an IBM-exclusive, is designed to take advantage of new system power management features, by providing power monitoring and power capping features. • Text Console Redirection support allows the administrator to remotely view x3550 M2 text messages over Serial or LAN. • The completely redesigned IBM Systems Director is included for proactive systems management. IBM Systems Director comes with a portfolio of tools, including Management Processor Assistant, Rack Manager, RAID Manager, Update Assistant and Software Distribution. In addition, IBM Systems Director offers extended systems management tools for additional server management and increased availability. When a problem is encountered, IBM Systems Director can issue administrator alerts via e-mail, pager, and other methods. • An optional Virtual Media Key provides additional systems management capabilities, including Web-based out-of-band control; virtual floppy and optical drive support; Windows “blue screen” error capture; LDAP and SSL support; and remote redirection of PCI video, text, keyboard and mouse. And it does all this without consuming a valuable adapter slot.
Dual Gigabit Ethernet Controllers The x3550 includes two integrated Broadcom 5709 Gigabit Ethernet controllers for up to 10X higher maximum throughput than a 10/100 Ethernet controller, as well as support for Jumbo Frames and TOE (TCP Offload Engine). Jumbo Frames—those larger than the standard frame (packet) size of 1,500 bytes—can be more efficient, dramatically increasing network performance and reducing server CPU overhead. TOE helps improve overall system performance by offloading TCP/IP protocol processing from the system microprocessor to the onboard Ethernet TOE processor. There is no additional charge for this capability. 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 GbE Ports via Broadcom 5709 GbE Controller. Up to four (4) GbE ports ideal for virtualization and I/O intensive workloads o 2 ports standard plus two additional ports optional via adapter card Improves system performance by offloading protocol processing from CPU to a separate engine Primary performance improvement for data copying (CPU) where CPU utilization is 90100% The embedded NIC/TOE supports software iSCSI using MS iSCSI initiator SW initiator enables offloading the processing of TCP frames with the TOE engine in the adapter card but the processing of iSCI packets themselves is not HW offloaded at the Broadcom NIC Broadcom HW offloaded iSCSI (using TOE engine) of the iSCSI frames ISCI and RDMA are not supported
Two Broadcom 5709 Gigabit Ethernet Controllers (one on-board and one on optional daughter card) provide four Gigabit ports supporting 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. This controller supports PXE 2.0 remote boot, TCPIP Offload Engine (TOE), Internet SCSI (iSCSI), Remote Direct Memory Access (RDMA), and jumbo frames (9KB). License key will be required to enable iSCSI and RDMA feature. There are two green LEDs on the connector: Activity LED on the upper left side and Link Status LED on the upper right side (viewed facing the connector). TOE support on Windows is available today. But, Requires Windows Scalable Network Pack (SNP) installed. Linux has no plan to support TOE at this time. Please refer to TOE_RDMA_iSCSI.doc for technology details.
