For more information about each of the current Blade models, see 1.

This configuration provides the following cost benefits over traditional rack mounted servers, among others: Blades and modules use the space inside their chassis efficiently, fitting more computing density into the same physical space.

Blade nodes share the management, networking, power, and cooling modules, offering lower overhead and cost savings. In contrast to traditional rack-mounted servers, most blades and chassis modules can be replaced without tools or special knowledge.

This advantage translates to improved reliability, faster service restoration after an outage, and cheaper support costs. Replaceable blades, storage, and networking modules mean that you can add new and alternative technologies without replacing entire servers, enduring long outages, or having to go through painful migrations. Blades make it easier than ever to try new ideas and technologies to improve your business.

Chassis The term chassis typically refers to the physical frame of the BladeCenter, including the interconnects that are contained within the frame: The midplane, power supply, and blower modules. Although the chassis does not possess any inherent intelligence, it does contain a significant amount of circuitry.

This circuitry is often referred to as paths within the chassis. These paths comprise the backbone of the BladeCenter and allow it to share the servers, switches, and power. Blade servers Any serve that is designed in the standard BladeCenter form factor is considered to be a blade server, or blade.

Blades are universal in size and shape. They can be inserted in any of the existing BladeCenter portfolio. However, processor power demands might prevent their usage in all chassis.

Blades consist of a system board, processors, memory, expansion ports, and two redundant midplane connections. Blades rely on the chassis to provide all necessary power, cooling, connectivity, and management. The midplane is set up so that there is a series of upper connection points and an identical set of lower connection points. These provide power and redundancy. On the opposite side of the midplane are other numerous connection points, which allow for power supply, blower, and expansion module bay connectivity.

The power supply and blower connections on the midplane function independently of their upper or lower status. However, the expansion bays are uniquely pathed to upper or lower connections points as they relate to blades. The midplane does not possess any intelligence. It is strictly a pass-through mechanism for blade, module bay, and power connectivity.

BladeCenter S also has a serial pass-through bay and two storage module bays. These bays are all directly connected to the midplane. However, they do not necessarily correlate to the upper or lower connections of the blade servers. Power supply and blower modules are independent of blade connectivity.

The management module bay can communicate to a blade through the upper or lower midplane connection. The expansion module bays have committed communication paths that are mapped directly to upper or lower connections for the blade slots in the chassis.

Advanced management module The advanced management module AMM is the center point for the BladeCenter infrastructure intelligence. The AMM is the primary means of management for the chassis, and controls all aspects of power, connectivity, and communication. It uses an upgradeable firmware and web user interface to run all routine hardware-based management tasks for blades, expansion modules, and configuration of storage modules.

The AMM also acts as a proxy for expansion modules. This configuration allows access by using direct that is, IP address or indirect that is, internal chassis methods for specific module management. The module has six external RJ45 console access ports on it, each of which is physically pathed directly to a blade slot. The module was designed for Chapter 1. Introduction to the IBM BladeCenter S chassis 7 26 serial console access only, and it is not intended for use by modems or other serial port devices.

Storage module The concept of a chassis with a self-contained disk subsystem or storage module is unique to the BladeCenter S. The module is fundamentally a collection of disk drives that are made accessible through a SAS module and a SAS daughter card. The SAS module is responsible for both the provisioning of physical disk drives through zoning and for failover redundancy when two SAS modules are present. The expansion card can address only those disks that are assigned to it from the SAS module, and can create arrays only from those disks.

There are various hard disk drive types available, so it is important to understand the features and benefits of each type. Certain considerations must be taken into account because there might be specific hardware requirements to support certain types.

Serial-Attached SCSI disks are designed for high performance requirements where maximum throughput and transaction capability is needed. Serial Advanced Technology Attachment disks are designed to provide lower-cost mass storage capacity, when compared to SAS disk.

They are designed for systems where performance is not a requirement. They do not fit well into server environments. It is intended to overcome performance and scalability limitations of bus topology while providing enterprise-class reliability and software stack compatibility. Because of its high performance, reliability, and scalability features, the SAS interface is widely used in the IBM System x server systems for both internal and external storage connectivity for wide range of applications and usage patterns.

In general, three types of devices form the SAS topology: The targets are the end-point devices, such as disk or tape drives.

The SAS expander is a switch device that connects more target devices to the initiator than the number of ports the initiator has. This dramatically increases SAS fabric scalability without sacrificing reliability and performance. In addition, expanders support wide SAS links or aggregated links that consist Chapter 1. Introduction to the IBM BladeCenter S chassis 9 28 of several narrow SAS links for expander-expander or expander-initiator connections to increase overall performance of the fabric Near line disk drives NL disks Data that are stored on an NL disk drive are intended to be accessed infrequently, but require 24x7 availability.

From the application perspective, these drives are commonly used for storing archives, document images, multimedia libraries, and backups. There are two types of NL drives: Because of these advantages, IBM System x servers always use NL SATA drives as they offer almost twice the reliability, better support of multi-drive RAID array deployments, and 24x7 hours of operation 24 hours per day, 7 days per week in multi-user workload environments.

They do so without significant cost disadvantage when compared to desktop SATA drives. A RAID array is a group of physical disks that uses certain common method to distribute data across the disks. The data are distributed by stripe units.

A stripe unit is the portion of data that are written to one disk drive immediately before the write operation continues on next drive.

When the last drive in array is reached, the write operation continues on the first drive in the block that is adjacent to the previous stripe unit written to this drive, and so on. The process of distributing data in this way is called striping. A stripe unit is a minimal element that can be read from or written to the RAID array.

Stripe units can contain data or recovery information. The particular striping method that is used for data distribution is also known as the RAID level. The RAID level reduces availability, performance, and available storage capacity because achieving redundancy always lessens disk space by the amount reserved for storing recovery information.

Spanned RAID arrays combine two or more basic RAID arrays to provide higher performance, capacity, and availability by overcoming limitation of the maximum number of drives per array supported by a particular RAID controller. This flexibility allows you to run all of your diverse workloads inside a single architecture.

The slim, hot-swappable blade servers fit in a single chassis similar to books in a bookshelf. Each blade server is an independent server with its own processors, memory, storage, network controllers, operating system, and applications. The blade server simply slides into a bay in the chassis and plugs into a midplane or backplane, sharing power, fans, diskette drives, switches, and ports with other blade servers.

The benefits of the blade approach are obvious to anyone tasked with running down hundreds of cables strung through racks just to add and remove servers. With shared switches and power units, precious space is freed up, and blade servers enable higher density with far greater ease. This book covers only a subset of the blade servers that are supported by the IBM BladeCenter S chassis, specifically the latest models.

The following servers are covered in this section: These servers can support up to two multi-core Intel Xeon microprocessors.
