iv BladeCenter S Type 7779/8886: Planning Guide

Chapter 1. Introduction
The BladeCenter®S Type 8886 is a high-density, high-performance rack-mounted
server system. It supports up to six blade servers that can share common resources,
such as power, cooling, management, and I/O resources within a single
BladeCenter S chassis. In addition, it provides support for up to twelve 3.5-inch,
hot-swappable SAS or SATA hard disk drives.
The BladeCenter S system provides the following features:
vIBM®Enterprise X-Architecture®Technology
IBM Enterprise X-Architecture Technology leverages proven innovative IBM
technologies to build powerful, scalable, and reliable blade servers. It provides
features such as IBM Predictive Failure Analysis (PFA) and real-time diagnostics.
vServer expansion capabilities
You can add up to six blade servers to the BladeCenter S chassis. Some blade
servers have connectors for additional optional devices that you can use to add
capabilities to the blade server. For example, you can connect either a storage
expansion unit or a PCI expansion unit to a blade server. Alternatively, you can
add optional I/O expansion cards to add network interfaces or storage through
I/O modules. SAS expansion cards provide access through SAS connectivity
modules or SAS RAID controller modules that are installed in I/O bays 3 and 4
to the hard disk drives in the BladeCenter S chassis.
Note: SAS connectivity modules support the use of SAS or SATA hard disk
drives. SAS RAID controller modules support the use of SAS hard disk drives
only.
vHot-swap capabilities
Bays in the BladeCenter S chassis are hot-swappable. For example, you can add,
remove, or replace a blade server or a SAS or SATA hard disk drive without
removing power from the BladeCenter S chassis.
The midplane provides hot-pluggable connectors for the following components:
– Six blade servers
– Four I/O modules
– One advanced management module
– One serial pass-thru module
– Four power modules
– Four fan modules
– Two storage modules
– One media tray
vHigh-availability design
Components in the BladeCenter S system enable continued operation if one of
the components fails:
–Power modules. In normal operation, the power modules provide power to
share the system load. If a power module fails, the working power modules
can continue to handle the entire load. You can replace a power module
without shutting down the BladeCenter S system.
© Copyright IBM Corp. 2007, 2010 1

Note: The power management policy that you have implemented for the
BladeCenter S system determines the result of a power module failure.
Power modules also provide cooling fans for the storage modules. Therefore,
if you are using storage module 1, you must install power modules 1 and 2. If
you are using storage module 2, you must install power modules 3 and 4.
–Fan modules. In normal operation, fan modules share the cooling in the
BladeCenter S system. If one fan module fails, the other three fan modules
handle the entire load. You can replace a fan module without shutting down
the BladeCenter S system.
–BladeCenter S system midplane. The midplane has the following
characteristics:
- Redundant high-speed serialize/deserialize (SERDES) interconnects
between blade servers and switches
- I2C communication between the advanced management module and all
modules (except blade servers)
- RS-485 (EIA 485) communication between the advanced management
module and blade servers
- Analog video connectors from the blade servers to the advanced
management module
- USB connections between the blade servers and the advanced management
module
–Redundant storage access. Installing a pair of SAS connectivity modules or
SAS RAID controller modules in I/O module bays 3 and 4 provides support
for redundant access to the storage modules in the BladeCenter S chassis (if
both storage modules are installed).
vSystems management
The advanced management module is used to communicate with the service
processor in each blade server to provide system monitoring, event recording,
and alerts. You can manage the BladeCenter S chassis, its devices, and the blade
servers remotely.

Storage modules
You can install a maximum of two storage modules in the BladeCenter S chassis
and each storage module contains hot-swap hard disk drives. A storage module
and the hard disk drives installed in that storage module are commonly referred to
as integrated shared storage because this storage is integrated in the BladeCenter S
chassis and shared among the blade servers in the BladeCenter S system.
Each storage module can support up to six hot-swap, 3.5-inch hard disk drives. If
you are installing SAS connectivity modules, both SAS and SATA hard disk drives
are supported, and you can use both types of hard disk drives in each storage
module. If you are installing SAS RAID controller modules, you must install SAS
hard disk drives.
Within each storage module, hard disk drives are numbered 1 through 6 from left
to right, and top to bottom.
Note: Each hard disk drive bay must contain either a hard disk drive or a
drive-bay filler.
6BladeCenter S Type 7779/8886: Planning Guide

Note: Four power modules are required in the BladeCenter S chassis if both
storage modules are installed.
To access the hard disk drives in the storage module, the following devices must
be installed:
vSAS I/O modules. You can choose to install either SAS connectivity modules or
SAS RAID controller modules.
Note: You cannot mix these module types in the same BladeCenter S chassis.
– SAS connectivity module. At least one SAS connectivity module must be
installed. If a single SAS connectivity module is installed, it controls access to
both storage modules in the BladeCenter S chassis. If two SAS connectivity
modules are installed, the module in I/O module bay 3 controls access to
storage module 1, and the module in I/O module bay 4 controls access to
storage module 2.
– SAS RAID controller module. Two SAS RAID controller modules must be
installed, one in I/O module bay 3 and the other in I/O module bay 4. Each
SAS RAID controller module will have access to both storage modules (for
high availability).
vA SAS expansion card in each of the blade servers, which provides access
through the SAS I/O modules in I/O module bays 3 and 4 to the SAS or SATA
hard disk drives in each storage module.
There is one LED on each storage module:
Fault Solid (amber) when there is a storage module failure.
Chapter 1. Introduction 7

There are two LEDs on each hard disk drive:
Green Flashing when an operation, such as a read or a write, is being performed.
Amber
Flashing when the hard disk drive is being rebuilt (fast blink) or identified
(slow blink).
Note: When power is restored to the BladeCenter S chassis after a
complete loss of power and you have implemented the hard disk drives as
a mirrored array, the fault light will blink as the hard disk drive is being
resynchronized.
This resynchronization occurs because the blade servers are attempting to
power on before all of the storage modules and SAS connectivity modules
are powered up and available. The mirrored array is accessible during
resynchronization although performance may be slightly slower.
Solid when there is a drive failure.
Media tray
The media tray contains the DVD drive (which can be either a CD-RW/DVD-ROM
drive or a DVD/RW drive) and two USB v2.0 ports, which are shared by the blade
servers. The media tray also contains two battery backup units, which provide
backup for SAS RAID controller modules cache
Note: The port on the side of the media tray is reserved for future use.
